From Weblogic To Websphere?

[kita]

Did any body has done a migration from weblogic to websphere?

[Kyle Brown]

Yes, my group at IBM (WebSphere Services) has done dozens. What in particular do you want to know about the process?

P.S. There is a redbook upcoming on this process...

How to move CMP beans from weblogic to websphere.
I have my beans and my tables. I want to know how to do the "Meet-In-Midlle"? Do I have to use Visual Age to do that? I have been working on this thing for a month, but no success.

You have to rely on VAJ or WSAD to migrate this OR mapping. WAS use VAJ Persistence Builder as PM in EJB container.
If you use TopLink for WLS OR mapping, then you can consider TopLink for WAS for this migration.

Actually, no WAS does not use the VAJ Persistence Builder for its CMP. The container implementations are totally different -- it's just that the tools are similar in V 3.5 and previous...
My advice is to use WSAD 4.0 to map to your tables. Failing that, the best way to learn about how the all-important XML binding files work in WAS 4.0 is to read my articles here and here
