Java EE (Java Enterprise Edition) General Discussion

I am working on a project by using WebLogic as EJB server, but we want to reduce the cost by changing EJB server from WebLogic to J2EE 1.4 Application Server.

I have a lot of problems when trying to migration the project to J2EE 1.4 Application Server.
And it seems that J2EE 1.4 Application Server doesn't suit large project.
The project I am working on including around 1000 Entity Beans 500 Session Beans, Plus Client side classes and JSPs, (This is not large, really).

But everytime I try to load (only load, not deploy yet) the jar, it took me 5 - 10 minutes. I have no idea what it is doing.

And many strange problems occur during the migration, and I couldn't find much information about J2EE 1.4 Application Server.

Could anyone who had experience with this server give any advice please?

Should I give up, or it is possible, but I was doing the wrong thing?


Thanks
