Oracle Cloud and Fusion Middleware, Oracle JET, Jakarta EE and all other Open Source Blog!

Hi, After a long time waiting for it, the Oracle Fusion Middleware 12.2.1.4 has been finally released. Oracle Fusion Middleware 12.2.1.4 Official Documentation In this post, I will focus on my personal view over the Oracle Fusion Middleware products which I most commonly use over the last 8 years which are the SOA Suite (including BPM and OSB), WebCenter Suite (Portal, Content, Sites), Oracle ADF and Oracle WebLogic Application Server mainly. Certification Matrix As every release, I make a round around the Certification Matrix of every Oracle Fusion Middleware Release to check if the Java JDK accepted has been increased or not. Oracle Certification Matrix for Oracle Fusion Middleware 12.2.1.4 Java However, I found that we are still in the J2SE / J2EE 8 and the maximum certified JDK is Oracle JDK 1.8.0_211+ which means any 1.8.0_xxx if you are using Oracle JDK as the JDK vendor. Database The biggest new is the certification with 18.3+ and 19.3+ of the On-Premise vers...

This is a post of the series Oracle WebCenter Portal to Oracle JET . In this case I will make another comparison between Oracle ADF Model and Oracle JET Common Model API . WCP to OJET How is the Oracle ADF Model It is not bad to remember that Oracle ADF is based on Java Server Faces 2.2 (Jakarta EE / Java EE). Oracle ADF adds to plain Java Server Faces the following features A Rich set of UI components -> ADF Faces A Model layer to abstract the interaction bewteen the Pages (UI) and the Model. -> ADF Model An implementation of JPA known as Business Components for consuming data from a Database -> ADF Business Components In Java Server Faces , the Model is implemented by Managed Beans as shown in the following Figure. JSF Model - Managed Beans In Oracle ADF , also can be used the ADF Model layer based on the withdrawn JSR-227. This layer is also known as the Binding Layer . The ADF Controller links a Page ( ADF Faces ) to a PageDefinition ( ADF Mo...

This is a post of the series Oracle WebCenter Portal to Oracle JET . In this case I will make another comparison between Oracle ADF and Oracle JET Architectures . Maybe this should be the second and not the third post, anyway here it is. WCP to OJET Oracle ADF is based on MVC (Model-View-Controller) Oracle ADF is a Java EE framework based on JSF 2.2 (Java Server Faces) which implements the pattern Model-View-Controller , but extending the classic Model of plain Java Server Faces based on Managed Beans. Oracle ADF introduces the ADF Model layer ( also known as the Binding Layer ), which was intended to be standarized (JSR-227) to be the way for data binding and access from the view to the sources of data, however it never was approved. The ADF Model abstracts the access to the business services independently of the data source (SOAP, REST, JPA) Knockout (library used by Oracle JET) is based on (Model-View-ViewModel) Oracle JET is a Toolkit which uses Knockout JS...

This is the second post of the series Oracle WebCenter Portal to Oracle JET. In this case I will talk about how to move ADF Task Flows or Portlets in Oracle WebCenter Portal to Oracle JET. WCP to JET ADF Bounded Task Flows and Portlets in Oracle WebCenter Portal The most common way of promoting re-usability in WebCenter Portal Pages is by embedding "widgets" built by using: Oracle ADF Bounded Task Flows based in Page Fragments which can be embedded in a Portal Page as an ADF Region ( <af:region> ) Portlets 2.0 (based on JSR 286) which are consumed remotely by using WSRP 2.0 (Web Service Remote Portlet) specification. Portlets can be based on ADF by using the ADF Portlet Bridge or based on any other Portlet technology. In the above image, you can see there is: A Portal Called Test. Currently in the Page called Home of the Portal Test . The Page has been configured with two components: The Activity Stream Task Flow The Page Traffic Analytics P...

Hi, I had some projects in the past where Oracle BPM has been involved and I have been asked many times on how can we improve the experience of Initiating an Asynchronous Process and redirecting Automatically to the first Human Task UI when available The code of this post can be found in my GitHub https://github.com/DanielMerchan/ActiveWaitingDemo Architecture of the Active Waiting Demo The following diagram describes the Architecture of the Demo. 1. The ADF UI Application starts a Asynchronous BPM Process by calling the start asynhronous interface exposed by the BPM Process. 1.a : The First Activity of the BPM Process registers in a CUSTOM database table the Process Info. This information is needed by useful administrative SOA API which is used to retrieve the Audit Trail and other statuses of a BPEL / BPM Process.   Note: The BPM Process has 3 Timer Activities to simulate processing before a Human Task is reached 1.b: The Poller starts first trying to get...
