We are working on Geronimo 2.0 which is Java EE 5.0.  The current  
work on the J2EE 1.4 is Geronimo 1.2 which is currently in beta and  
available from

 From WebSphere not really.  There are some limited conversion tools  
available but w don't have a comprehensive conversion suite.  Help  
would be excellent.

It depends on the nature of the application you are converting.  For  
the Application you described above it sounds like choosing Apache  
Geronimo 1.2-beta would be a good choice.   If you need CORBA you  
will have to use the Sun JDK.   If not, then I think just about any  
1.4 JDK will work as should 1.5 JDKs.  One thing to note is to choose  
a JDK level and stick with it.  If you are using WebServices you will  
have some difficulty changing JDK versions back and forth.
