Web Dynpro application crashes on startup

Hello Everybody,

I have developed a web dynpro application. The application worked fine. But we have applied the patch level 12 to the NWDS(I mean 2.0.12) today. When I am tried to rebuild, deploy and run the same application,It crashes with the following error. I have also with another new application from scratch but the same error. We have not altered the server settings.

Can anybody suggest the reason behind.

Thanks in advance

Satish
