Developing with JAX-RS 2.0 for WebLogic Server 12.1.3

In an earlier post on the topic of Using JAX-RS 2.0 with WebLogic Server 12.1.3, I described that we've utilized the shared-library model to distribute and enable it.

This approach exposes the JAX-RS 2.0 API and enlists the Jersey 2.x implementation on the target server, allowing applications to make use of it as when they are deployed through a library reference in a weblogic deployment descriptor.

The one resulting (more...)

Using Eclipse (OEPE) to Develop Applications using WebSocket and JSON Processing API with WebLogic Server 12.1.3

Following from my last posting, I thought I'd also show how Eclipse (OEPE) makes the new Java EE 7 APIs available from Oracle WebLogic Server 12.1.3.

The first step was downloading and installing the Oracle Enterprise Pack for Eclipse (OEPE) distribution from OTN.

http://www.oracle.com/technetwork/developer-tools/eclipse/downloads/index.html

Firing up Eclipse, the next step is to add a new Server type for Oracle WebLogic Server 12.1.3, pointing at a local installation.

Getting started with SwitchYard 2.0.0.Alpha1 on WildFly 8.1.0.Final

I've been sticking my head into some hot RedHat technologies lately and among the many interesting parts I found SwitchYard. Without being disrespectful towards everybody wrapping their heads around SOA and service oriented architectures in the past, this has always been kind of weird to me as a Java EE developer.

In the past I've been building component oriented applications with what I had at hand. Mostly driven by the features available in the Java (more...)

Being Right and Proving It

One of the great things about working in IT is that you can often win an argument simply by being right. Not because of who you are or because you are more eloquent than others, but because the facts support your position. Almost every IT person I have ever met respects facts.

In order to win arguments this way, you of course need some facts to work with. And that’s where too many people fail. (more...)

I would like to highlight one interesting improvement implemented in 12c MAF - out of the box support for Master-Detail relationship. In previous 11g release, master (more...)

ADF 12c (12.1.3) Line Chart Overview Feature

ADF 12c (12.1.3) is shipped with completely rewritten DVT components, there are no graphs anymore - they are called charts now. But there are much more, besides only a name change. Previous DVT components are still running fine, but JDeveloper wizards are not supporting them anymore. You should check ADF 12c (12.1.3) developer guide for more details, in this post I will focus on line chart overview feature. You should keep (more...)

Use tree binding accessors to show detail rows

Tree bindings can be very handy, for example to combine details in the same row as the master. Let’s assume we have the following starting point based on the HR schema:


We see the department in a form layout with navigation buttons, with a table under the form showing information about the employees. As you can see in the screenshot below in the ApplicationModule, there is also a Jobs detail under the EmployeeView.

New in Java 8 : Default and static methods in interfaces

Default method’s  (aka Defender methods) in interfaces are new in Java 8. They enable you to define a default implementation of a method in the interface itself.

If an interface is implemented by several classes, it’s hard to add method’s afterwards, as it will break the code and require all implementing classes to define the method as well. Adding a method to the interface, and defining a default implementation for it, will resolve this problem.

ADF BC 12c New Feature – Entity-Level Triggers

We have triggers support in ADF 12c! Powerful new feature is available - Entity-Level triggers. Previously it was often confusing if certain use case belongs to validation rule, or it is more generic business logic. Everything was implemented as part of validation rule in the EO. ADF 12c provides cleaner approach by supporting option of Entity-Level triggers, along with regular validation rules. Validation logic can be implemented as part of validation rule, non-validation (but still (more...)

Debugging Faulty Assumptions

I wanted to install Oracle JDevelper 12.1.3 – a version that I had been eagerly awaiting. Since my primary machine is a MacBook, I wanted to install it on OS X 10.9.3.

I downloaded the generic installer and found that the install didn’t run. Since OS X had disappeared from the documentation, I assumed that I would have to fiddle around until I found a combination of JDK and OS (more...)

Farewell msg systems …

.. and thank you for amazing 14 years. It's true: I've been within the msg group for an incredibly long time  and have been working in the Java/Java EE space almost all of it. Next Friday (07/11/14) will be my last day. Now it is time to move on.
I've been working with customers and internal Java EE projects all over the place, blogged, authored articles and have been speaking at conferences a lot. The passion (more...)
