Hi Padma

Are you getting a blank screen when u try to login?

Which patch level are u on?

What is the heap size of the system? If it is 256 MB, change it to 1024 MB.

Can you please post ur default trace as well?

Thanks

Hi Padma,

Check your version of NetWeaver developer studio and Web AS on same SP level.

Same problem but solved see the following threads:
