Need your suggestions...

[Hari Krishna Korrapati <ha...@gmail.com>]

Hi Experts,



We have list of J2EE application (components
Servlets,JSP,Struts,EJB,Hibernate) currently running on Websphere WAS4.0.5
with JDK1.3.

Our plan is to Migrate to Apache Geronimo application server with latest JDK
whatever it supports.

Currently few migrated to Apache Geronimo 1.1.1.



What are the future releases are going to be and time plan/special features.



Want to know any tools available to automate the migration process or can we
customize.

What are the Best Practices and Approaches for migration



Your thoughts are highly valuable.

Hari

Because Yoko wasn't functional in the 1.2-beta

I'm not sure why you say this.  AFAIK we haven't tried any other jdks  
but yoko should run fine in any 1.4+ jdk.

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 http://geronimo.apache.org/downloads.html

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

> What are the Best Practices and Approaches for migration

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.
