The JSRs 299/330 are pretty interesting as they offer a nice way to use its flexible structure to easily add new features. For instance inside of the Apache implementation (Apache OpenWebBeans) there is already some extension that adds decent support for the JSF2.0 @ViewScoped annotation. The commit shows that the implementation of this wasn’t that [...]

The Apache MyFaces project is very active on the JSF 2.0 front. Recently the first alpha of the MyFaces 2.0 package has been released. Download the alpha here. Today, the Apache MyFaces Trinidad community also released the first alpha release of its JSF 2.0 efforts. Get the download here. In the middle of January we [...]

I mentioned earlier that ADS is pretty much model driven and requires no extra sit-ups in the declarative view. It supports (currently) the following ADF components: activeCommandToolbarButton activeImage activeOutputText table tree All DVT components Most examples that are viewable (or documented) provide an introduction on “How to combine ADS with collection-based data”. Let’s take a [...]

Here is how to close an obsolete registration from JDBC in a case where you don’t have a valid DatabaseChangeRegistration object (for example a JVM crash). 1. Find the obsolete registration as [...]

Normally I would create an EJB session bean to expose my Entity queries from my Entity beans, but I thought it would be easier to just create a Java Service Facade and expose that as a web service as shown below. 1. In my project create an “Entity from table” using the new object gallery [...]

Started setting up some coherence demos through ant, in doing so created a small template to work from which enables me to start a coherence cache server. With this you simply place your source code within the SRC directory and it will compile it, package it (once we add a package task), and run the [...]

I came across a curios bug where the WSDL uses HTTP Binding rather than SOAP Binding. This caused all sort of hell with the proxy wizard in JDeveloper, which I am working on, but I still ran into problems when I tried to run the client that was generated from the wsimport tool. It turns [...]

In the latest release of JDeveloper (11.1.1.2.0) we’ve added new declarative UIs to help simplify those most crucial and complex of SVN tasks – Merging and Branching.
