JSR-352: Batch
I, the Java EE application developer, wish to create new and maintain Batch (JSR-352) applications in Eclipse. I need XML editing support, content-assist where appropriate and a Maven-based quickstart to help with getting started.
The quickstart should be easily importable into JBDS and allow for editing so that I, the Java EE app dev, can "make it my own" by changing its project name, group, artifact id and version, plus modifying the XML file, adding/removing classes, etc.
This effort should primarily be focused on the XML editing experience. The normal New Java Class wizard should support the batch related super classes (extends). Run As Run on Server should work as well.
Examples of the XML:
