I am facing a problem with my application.

This application acts as web-service proxy.

It works fine in WTK2.5

I compiled the same code in JDE 4.1.0 and 4.2.1 and there was no errors.

But when I try to execute in JDE 4.1.0 and 4.2.1 it shows uncaught error the description is
"Module 'xxxx' has verification errors" .

In which way I have to solve this problem?
