Hi Folks,

We need to migrate a J2EE application from version 1.3 to version 1.4.

1. The first thing I don't really understand is what does it mean when we say we are migrating from version 1.3 to version 1.4? Does it mean we need to start using all new API & structure provided in 1.4? Or does it mean just changing the Meta data like ejb.xml, web.xml - so that they now reflect the new standard?

2. We have RAD 6.0 and RAD has a feature to migrate J2EE code from 1.3 to 1.4. After than happens the change happens in only a few META files - no code changes seem to take place. Is it enough to run the migration wizard tool to convert the code to J2EE 1.4 or are there in more changes to look out for?

Any online resources which might help us?

TIA for any help that you can provide!

My general response would be the same I gave in Migrate the J2ee application from from jdk1.4 to jdk1.5. No code changes should be necessary, since J2EE -like J2SE- generally is backwards-compatible.
