JDeveloper Scales Down Support For Apache Struts
Oracle have announced they will partially remove design time support for Apache Struts from the next major version of JDeveloper 11g. In particular, JDeveloper 11g will no longer feature enhanced editor and diagramming support for Struts Pageflows. In the future, developers will only be able to interact with the Struts code and metadata through the basic Java and XML editors. The ADF + Struts Runtime environment will not be affected.
The latest production release of Struts is Struts 18.104.22.168, which was released in November 2009.
