problem in moving the code from one computer to other

Hi,

I am working on building a webservice. I started building the EJB teir compnents like (Entity beans, Sessions beans, data base schemas) using the SUN ONE STUDIO 5 and SUN ONE App Server 7.0.

The problem, if I want to move the same entity beans code from one computer to other computer.

I am using same platform except the operating system (XP, and Windows 2000), apart from this every thing is same (Sun one studio 5, sun one app server 7.0). The Entity beans are working on the source computer and tested the beans. But When I moved the code to other computer, I compiled the entity beans code and it compiled perfectly. Then I tested the entity bean, I generated the test client, and deployed it. Till now no problem. When I tried to excute it and invoke the functions then it giving the following error:

Is there any solution, so that I can avoid coding from scrath again when I want to use same on other computer.
