WSAD 5.0 on XP

I have Windows XP Pro in my system that has Websphere Studio Application Developer 5.0 installed.
However I have a problem that haven't found out a solution yet.
I create a J2EE application and basically it creates 3 different modules web,ejb,application client. After that I created a simple servlet it didn't work.
Then I created a "different enterprise project" and put it on the test enviroment and started the server.But the server gave an error and stopped the application.
By the way: When I create web sproject only it works fine.Thew problem seems to be in ejb part.But why.Even I do create EJB or not the server fails to start my applications.
Has anyone met this sort of problem?Everything was going fine with 4.0 version.But I have to demonstrate EJB 2.0 on my platform thats why I am trying to use 5.0 version.Any suggestion welcome.

Thanks.

I would need more detail about what specific errors you are seeing to diagnose, but I'll take a few guesses and offer some suggestions. First the guess: Assuming you are using the test environment, are you perhaps specifying WebSphere Application Server Express? That particular server doesn't support EJBs and the error that results isn't obvious in its explanation.

Since it sounds like you've only recently started using WSAD, I suggest starting with the samples. The "Auction" scenario is simple to install and verifies that everything is correctly installed (e.g., your database); this tutorial is more EJB-centric. The tutorial includes detailed step-by-step instructions which should take you an hour or so. The "Hospital" scenario is about web services and is more involved than Auction.
Once you've successfully done these tutorials, I suspect the solution to the problem you're seeing will be self-evident. If not, repost with more specifics and I'll try to help.

Salih,
Do you have any errors or warnings in your workspace? Also, there is an IBM/Websphere question further down. More WSAD experts may hang out there.
