Ant Directory structure.

Question

Hi,
We are developing J2EE application that would contain number of components. Each component would be a ear file that would contain EJB jars and war which can be deployed in any J2EE compliant application server.
We are currently using Bedrock framework for applications deployed in Weblogic. It provides a very robust directory structure with most of the ant targets. However it is very custom for Weblogic.
Is there a similar framework that provides a robust directory structure (with built ant targets) which can be delopyed into Orion/Oracle Application Server.
If not, is there any standard directory structure for building J2EE applications? Any recommended source directory structure and why?
Any help is greatly appreciated.
Thanks
Sumanth

like this the folderers are created for modularizing and also separation of code for
easier maintainance.
the Build.xml for ant i am posting here
