Back to top WebLogic section Getting started with Java Cloud Service on the Oracle Public Cloud (WebLogic as a Service) by Lucas Jellema The Java Cloud Service (JCS) in the Oracle Public Cloud allows me to deploy Java EE applications such as JAX-RS and JAX-WS REST and SOAP Web Services, Servlet | JSP | JSF Web Applications, EJB and JMS artifacts and ADF applications to the public cloud and make them accessible to developers, testers and end users anywhere in the world. For components to be deployed to the JCS – I have to do nothing special (!) during development or deployment: anything that runs on premises will run in JCS. In this article, I will describe some of my initial experiences with JCS: what did I have to do to get going the first time – from having nothing more but a (trial) subscription to JCS to deploying and running my first Java EE application on JCS. I thought this would be a very long article with a large number of tips and tricks and with deeply technical steps. I felt some reluctance to even get going – feeling a little daunted by a new world full of new terminology. As it turned out – this is not a long article and it certainly does not contain a lot of tips. My initial reluctance was misplaced. JCS is just WebLogic – hosted on a different machine than my laptop and with a different provisioning interface. The amount of cloud terminology is limited (cloud account, identity domain, service instance is probably the bulk of it – along with simple tooling: dashboard, service console). JCS builds on three other Oracle Public Cloud Services that we need to be aware of: DBaaS (Database), Compute Cloud Service and Storage Cloud Service. You do not need guidance from me for all the steps you need to go through. I worked with an excellent tutorial on Oracle Help Center – Getting Started with Oracle Java Cloud Service – and I heartily recommend you do the same. The steps (described in this tutorial) that you need to go through in order to have your first Java EE application running are: (do: 5 minutes | then wait: days up to months) Get a [Trial] Subscription to the Oracle Java Cloud Service – for your Oracle account (the same one you use for OTN and any other interaction with Oracle); an Oracle Java Cloud Service trial environment or purchased subscription comes with Oracle IaaS Public Cloud Services, which provides you access to Storage CS and Compute CS – both of which underpin the JCS instance; Note: Database Cloud Service is a prerequisite of Java Cloud Service and is priced separately. When you request provisioning of an instance of JCS, you need to specify the DBaaS instance that it should make use of.  Read my previous article on DBaaS to get going with the Oracle Database as a Service offering and prepare a database instance. (do: 5 minutes) Associate the [trial]subscription with an existing or a new Oracle Public Cloud account (and thereby to an identity domain) (do: 5 minutes) Generate SSH keys (you can reuse the SSH key pair you may already have created to get going with Oracle DBaaS) Read the complete article here. Back to top Deployment of a Java EE application to Java Cloud Service (Oracle Public Cloud JCS) by Lucas Jellema In this previous article – Getting started with Java Cloud Service on the Oracle Public Cloud (WebLogic as a Service) – I have taken  you on a introductory tour into JCS. That article describes how to get going – how to provision a JCS instance – associated with an instance in DBaaS and with backup set up with Storage CS. In the article you are currently reading, I show you how to use this instance for deploying a Java EE application onto – and subsequently invoking that application. Since the same consoles are available to us with JCS as with on premises WLS, we can perform an application deployment in the same way from the console by uploading a WAR or EAR file as we can do on premises. I tried my hand at a fairly large application – without any Java EE dependencies (no EJB, JMS or JDBC data source requirements): the ADF Faces Rich Client components Demo application – available from http://www.oracle.com/technetwork/developer-tools/adf/downloads/index.html. The downloaded file is about 105 MB. The subsequent deployment of this file to JCS fails: the step takes quite long – because 105 MB have to be uploaded again, from my laptop into the Oracle Public Cloud. This console could be extended by Oracle perhaps to also offer to upload directly from a URL. On three attempts, after about three minutes into the upload, the deployment process fails. Either on the JCS end or in the browser to server communication is a problem. I am not sure what it is caused by. For now, I will simply try my hand at a smaller WAR. Plan B or Take Two at deploying a Java EE application Instead of looking around for a suitable ready to deploy WAR file, it is probably even more rewarding to quickly develop a Java EE application, build it as a WAR file and deploy it to my new JCS instance. Using JDeveloper, I quickly whip up a JAX-WS application: a simple Java Class that with some JAX-WS applications is turned to a SOAP Web Service (by right clicking the Class and selecting the option Create Web Service): The functionality of this service should be fairly obvious from the code. The WSDL that the derived service exposes can be previewed in JDeveloper: Deployment of the service can be done from the project navigator: right click on the ViewController project: Read the complete article here. Back to top Java Rock Star Adam Bien Impressed by WebLogic 12.2.1 by Reza Rahman It is not an exaggeration to say Adam Bien is pretty close to a "household name" in the Java world. Adam is a long time Java enthusiast, author of quite a few popular books, Java Community Process (JCP) expert, Oracle ACE Director, official Oracle Java Champion and JavaOne conference Rock Star award winner. Adam most recently won the JCP member of the year award. His blog is amongst the most popular for Java developers. Adam recently took WebLogic 12.2.1 for a spin and was impressed. Being a developer (not unlike myself) he focused on the full Java EE 7 support in WebLogic 12.2.1. He reported his findings to Java developers on his blog. He commented on fast startup, low memory footprint, fast deployments, excellent NetBeans integration and solid Java EE 7 compliance. You can read Adam's full write-up here. None of this of course is incidental. WebLogic is a mature product with an extremely large deployment base. With those strengths often comes the challenge of usability. Nonetheless many folks that haven't kept up-to-date with WebLogic evolution don't realize that usability and performance have long been a continued core focus. That is why folks like Adam are often pleasantly surprised when they take an objective fresh look at WebLogic. You can of course give WebLogic 12.2.1 a try yourself here. There is no need to pay anything just to try it out as you can use a free OTN developer license (this is what Adam used as per the instructions on his post). You can also use an official Docker image here. Solid Java EE support is of course the tip of the iceberg as to what WebLogic offers. As you are aware WebLogic offers a depth and breadth of proven features geared towards mission-critical, 24x7 operational environments that few other servers come close to. One of the best ways for anyone to observe this is taking a quick glance at the latest WebLogic documentation. Back to top WebLogic on Docker Containers Series, Part 2 by Bruno Borges On my previous post, the first part of this series, I've shown to you how to quickly get started with WebLogic on Docker. You've learned how to create a base Docker image with WebLogic and Oracle JDK installed, and then how to create a second image that contains a configured WebLogic domain. Today's post will break down and explain what happens behind the scenes of that process. Note: for the sake of history and keep this blog post useful in the future, I will refer to the commit 7741161 from the docker-images GitHub project, and version 12.2.1 of WebLogic. Walking through the build process of a WebLogic base image A base image of WebLogic means an image that contains only the software installed with minimum configuration, to further be extended and customized. It may be based on a Red Hat base Docker image, but preferably, we recommend you to use the Oracle Linux base image. Samples for how to build a base image are presented in the dockerfiles folder. Files for WebLogic versions 12.1.3 and 12.2.1 are maintained there, as well for two kinds of distributions: Developer, and Generic. Other versions and distributions may be added in the future. Differences between Developer and Generic distributions There aren't many differences between them, except these (extracted from the README.txt file inside the Quick Installer for Developer): WHAT IS NOT INCLUDED IN THE QUICK INSTALLER Native JNI libraries for unsupported platforms Samples, non-english console help (can be added by using the WLS supplemental Quick Install) Oracle Configuration Manager (OCM) is not included in the Quick installer SCA is not included in the Quick Installer Also, the Quick Installer for Developers is compressed using pack200, an optimized compression tool for Java classes and JAR files, to reduce the download size of the installer. Besides these differences, the two distributions work perfectly fine for Java EE development and deployment. Building the Developer distribution base image Although we provide a handy shell script to help you in this process, what really matters relies inside 12.2.1 folder and the Dockerfile.developer file. That recipe does a COPY of two packages, the RPM of JDK, and the WebLogic Quick Installer. These files must be present. We've put these .download files as placeholders to remind you of the need to download them. This same approach will apply for the Generic distribution. Read the complete article here.

Back to top WebLogic 12.2.1 Multi-Tenant by Raul Castillo As a weblogic administrator the interaction among the application server and the database is often strong. In fact, according to Confio Software (2013) approximately 70% of applications’ performance problems are caused by the dataWith the development of partitions on WebLogic, Oracle has developed an infrastructure that is similar to containers and that takes advantage of the WebLogic server’s capacities such as clustering, transaction management and security [1]. These are the advantages of using WebLogic Server Multitenant [1]: Time to market is improved. The complexity of moving workload to the cloud and from the cloud is reduced. It is possible to convert monolithic applications to smaller services. It allows up to 3x hardware consolidation. Reduction of OPEX by up to 25% Since WebLogic Multitenant is based on the concept of partitions or micro containers. It is important to remark that these partitions allow the portability of applications reducing the time to market and allowing the movement to the cloud or vice versa. Multi-tenant allows group applications that are scattered through several domains, which helps to optimize the use of hardware, making possible the reduction of OPEX. In addition, a partition does not have any Operating System or JVM component. Applications and configuration artefacts compose partitions or micro containers and each one of these micro containers could use a managed server or a cluster. In the following diagram, the topology shows two partitions deployed on the same cluster, which allow them sharing the JVMs that are part of that cluster. With this in mind, in this post, I will show you how to reach the topology described based on partitions. I have created a domain with a cluster and I have an Oracle Pluggable Database available so now these are the additional elements created in this post: Virtual targets. According to [2] a virtual target is the target used by a resource group at the domain level and partition level. Virtual targets are targeted to managed servers or clusters and they define access points to resources. Virtual targets give a separate HTTP per each server as in the case of virtual hosts in WebLogic Server [2]. Since virtual targets set the access to resources and resources are group by resource groups, these require one or more virtual targets. When a resource group has a global scope (related to the domain) it is possible to select any virtual target that is not assigned to a partition. On the other hand, when a resource group is assigned to a partition, this can use only available virtual targets in the partition [2]. Read the complete article here. Back to top Resource Consumption Management with WebLogic Multitenant by OTN What is WebLogic Server Multitenant? Multi-tenancy (MT) in WebLogic Server (WLS) provides a sharable infrastructure for use by multiple organizations. These organizations are a conceptual grouping of your own choosing, which you can think of as tenants. By allowing one domain to support multiple tenants, WebLogic-MT improves density and achieves a more efficient use of resources. WebLogic-MT provides resource isolation within a domain partition, an administrative and runtime slice of a WebLogic domain that is dedicated to running application instances and related resources for a tenant. Domain partitions achieve greater density by allowing application instances and related resources to share the domain, WebLogic itself, the Java virtual machine (JVM), and the operating system, while isolating tenant-specific application data, configuration, and runtime traffic. Read more about WebLogic-MT here. What is Resource Consumption Management? A premium feature in WebLogic-MT 12.2.1, Resource Consumption Management (RCM) provides resource isolation and tries to ensure that resources are allocated fairly to the partitions. It provides a policy infrastructure to limit usage of the shared resources and take appropriate actions when those specified limits are breached. It can also help maximize resource utilization in consolidated deployments. Why is RCM important? As we saw, in WebLogic-MT there can be one or more co-located partitions in a single JVM. When partitions are co-located, they may consume or compete for the low-level resources offered by the OS/JVM. Low-level resources are often limited in nature. The (over-) consumption of these resources by one partition may (adversely) impact the other co-located partitions. Therefore, in WLS-MT, where partitions are co-located, it is important to isolate these partitions and the resources consumed by these partitions. For example: If there are 100 file-descriptors available on a particular OS running WebLogic-MT that has 2 co-located partitions, one partition may end up consuming most of the available file-descriptors, leaving absolutely nothing for the other partition (implying the affected partition cannot function as expected). The affected partition has to bear the cost of being co-located with As we can see, the Blue tenant is affected adversely because the Red tenant consumed most of the shared resources. The solution is to enforce policies through the RCM, so that one partition does not end up consuming all the low-level resources. With RCM, the system admin can define policies so the consumption of resources by one partition does not adversely affect the other co-located partitions. Read the complete article here. Back to top Internet of Things Cloud Service is Now Available by Eric Jacobsen The Oracle IoT Cloud Service is a secure and scalable platform to help organizations quickly build and deploy IoT applications.

Back to top Development tools section Mobile Cloud Service 3 Days Workshop in Madrid by Rubén Rodríguez Santiago Last week I had the chance to attend a Mobile Cloud Service 3 days workshop in Madrid. This was the first MCS training in Spain where some partners and I were able to get a good insight about what MCS offers and also a complete hands-on. If you want to know MCS functionality you can check my previous post: Oracle Mobile Cloud Service overview. Although I already attended Oracle Summer Camps workshop in Lisbon, we are in the middle of a MCS development and  this workshop was a perfect fit for mastering my MCS skills and also any question we made was perfectly answer by Mireille Duroussaud (Senior Principal Product Manager). We were also able to see some of the features that will bring the next versions of Mobile Cloud Service like Mobile Application Accelerator (Oracle MAX), and hear of others like for example a JavaScript editor for implementing and debugging APIs right in the browser. I was really impressed about Oracle MAX becasue building a Mobile Application connected to Mobile Cloud Service was just a matter of 10 minutes. Although the things you can do with Oracle MAX are limitted, it is likely possible that we will be able to donwload the source code of the generated application to extend it wich is a nice feature.

Back to top Handling ADF BC 12.2.1 REST Validation in Oracle JET by Andrejus Baranovskis CRUD use case would not be complete without validation logic implementation. Oracle JET allows to implement standard and custom validators on the client. Probably most of the simple to average complexity logic will be implemented in Oracle JET. Complex use cases can be handled in ADF BC validation rules, data will be validated through REST calls. When validation fails in ADF BC, error message is propagated through REST back to Oracle JET client, where we can parse it and attach to the UI field. You can watch demo video, it shows how it works. I'm trying to update a row with invalid data, rules are executed in ADF BC and validation messages are displayed next to the UI fields in JET: There are three rules defined in ADF BC. It might be tricky to map UI field with error message. This is easy in case of PATCH method, ADF BC REST returns failed attribute name together with the message. This doesn't work in the same way with POST method, when new row is created. For this reason, I have introduced custom indicator into each validation message *AttributeName*. I'm parsing this value in JET, to understand which UI field should be marked as incorrect. Rule 1. Unique Key validation rule for Email attribute. Rule 2. Hire Date validation rule, it should not be in the future. Read the complete article here. Back to top Push Notification to delete local data oham Dasgupta Power of PUSH In this blog I will explain how you can use Push Notification to delete data saved in local SQLLite database. What I'll explain: Simple MAF app, which will create a table and put some data in it while loading for the first time. It will have one page to display the data stored in the local database. I will configure MCS to send Push notification to the MAF app. On receive the MAF app will fire a delete statement to remove all the data form local database. Requirements : MAF 2.2 MCS or any push server GitHub link : https://github.com/sohamda/PushAndDelete/ The basic architecture of this solution is : Step #1: Configure MCS Backend with Google Project ID and Prepare your MAF code You need to create a Google project and enable messaging API. Then configure the MCS backend with the details. Then create your MAF application to register with MCS to receive push notifications. You can find all the steps here Step #2: Create table and add sample data while app loaded for the first time Add a DB script to create a table and add some sample data, put the script inside ApplicationController > META-INF Read the complete article here. Back to top ADF: Filtering parent and child nodes in af:tree / af:treeTable by Rubén Rodríguez Santiago One of our customers required to filter data in a page with a tree component. Using Ashish's post I am going to show you how to filter both parent and child nodes having just a single filter value. This can also be applied to treeTable component. The first thing we need is a tree component and data structure, in this case we are going to use Oracle's hr schema tables: Departments and Employees. In our page we drag and drop DepartmentsView from datacontrols palette and create a tree component. The next thing we have to do is to create a View Criteria in Departments View Object (parent).

Back to top Automatic ADF Logout on Browser Close with WebSocket by Andrejus Baranovskis Every ADF project could have a requirement to handle browser close event effectively. Differently than desktop applications where we could handle such events, browser doesn't send any event to the server, when browser page is closed. This is especially important for transactional data, when user locks data row and lock must be released automatically, in case if user is closing browser without unlocking. Besides transactional data management, it is important for performance improvement - Web session will be closed instantly and WebLogic resources will be released. There was no reliable solution to handle this, now we can do it with WebLogic 12c and WebSockets. WebLogic 12c supports WebSockets natively, there is no need to configure anything or add libraries. When WebSocket channel is closed, it delivers event to the server on browser close. We could use this event to release locked resources, we need to logout ADF session to force ROLLBACK. Sample application implements HTTP client invoked by WebSocket server endpoint. This HTTP client simulates browser activity and redirects to adfAuthentication with logout request, using original JSESSION ID from closed browser session. This works also during accidental client computer power off. Download sample application where I have described all important implementation steps - ADFSessionHandlingWebSocket.zip. Sample application is protected with ADF Security, you can login with redsam/welcome1 user. It includes Oracle JET libraries, one of the dashboard tiles implements JET fragment. JET is not required for the sample to work, it is used only to implement dashboard UI. You can observe from browser log when WebSocket connection is opened. Connection is established on initial page load, immediatelly after login. This opens WebSocket communication chanel, as soon as this chanel will be closed - WebSocket server endpoint will force logout for ADF session from closed browser. As soon as WebSocket channel is established, ADF web session ID (JSESSIONID is retrieved from the cookie) is sent to WebSocket server endpoint. Sample logs ID of ADF web session: Read the complete article here. Back to top Close the containing parent popup component without binding using an actionEvent by Marvin Muuß When using popups in ADF we suffered the problem to close the popup after finishing the activity. So this is the request: We have a table providing data with an info facet holding buttons for adding, editing and deleting a selected row. While the add and edit button open a popup with a form the delete button opens a dialog to confirm the delete action. This is realized with a showPopupBeavior. Of course there is a cancel button in all of these popups closing it immediately and rolling back.  So this is an example what a popup might look like. As the cancel button immediately rollbacks, the save button immediately commits the made changes. This cancel button is just out of the box, closing the dialog and not rolling back because there is nothing to rollback. But delete executes this action, commits and closes the dialog.

In same way we can populate values in selectOneListBox as both ADF Faces components are used for single selection and share same structure Here i have used a List to populate values in selectOneListBox (For details read complete article in above link). And to get selected value from af:selectOneListBox/selectOneChoice in bean- Used a String variable, created it's accessors. And see here how both List and String variable are bound to af:selectOneListBox. Read the complete article here. Back to top Edit Use Case for ADF 12.2.1 Dashboard with Masonry Layout by Andrejus Baranovskis I was researching ways to implement edit functionality for dashboard created with ADF 12.2.1 masonry layout. Check my previous post, where dashboard was implemented - ADF 12.2.1 Responsive Dashboard with Masonry Layout. I have decided to use panel drawer component, which would bring editable fields in the context of data displayed in the dashboard. Panel drawer icon is displayed in the top right corner of the dashboard. User can click on the icon and this shows editable form for the data rendered in the dashboard: Dashboard is implemented with masontry layout, it makes it possible to re-arrange tiles. This proves to be useful when editing data. I can move tile with the chart and change salary value. Chart is synched and new value becomes visible. Two actions are done at once - data update and change review in the chart: One more use case - validation. While editing salary, we can check tile with minimum and maximum salary values. This could help to understand, what salary value can be accepted. For example, if too low salary is set, validation error is returned. User can cross check this in the chart with minimum and maximum values: Read the complete article here. Back to top Consuming a SOAP Web Service quickly using Web Service Data Control (WSDL) in ADF by Ashish Awasthi Creating and Consuming Web Servie is an important part development cycle . In earlier posts i have described about creating SOAP/REST Web Service Create REST Web Service with Application Module declaratively in ADF 12.2.1 Create SOAP Web Service with Application Module quickly in ADF 12.2.1 Now this post is about consuming a SOAP Web Service. A very simple way to consume Web Service is to create Web Service Data Control (WSDL) for external Web Service URL. Here i am using a Country-Currency Web Service (http://www.webservicex.net/country.asmx) to create WSDL. Create a Fusion Web Application with default Model and ViewController project Right click on Model project, Select New--> From Gallery--> Business Tier--> Web Services and select Web Service Data Control SOAP/REST It opens WSDL creation wizard , First Step is to provide Web Service Name and URL.

Data could be changed by third party process or by different client session. Notification implementation is important, when we want to inform client about changes in the data, without manual re-query. I had a post about ADS (Active Data Service), where notifications were received from DB through change notification listener - Practical Example for ADF Active Data Service. Now I would like to focus on change notification listener, because it can be used in ADF not only with ADS, but also with WebSockets. ADF BC is using change notification to reload VO, when configured for auto refresh - Auto Refresh for ADF BC Cached LOV. Change notification is iniatilized by DB and handled by JDBC listener. There are two important steps for such listener - start and stop. Sample application - WebSocketReusableApp.zip, implements servlet DBNotificationManagerImpl. I'm starting and stopping DB change listener in servlet init and destroy methods: Read the complete article here.
