Hi,

You might need a Porting Set upgrade.

According to KB 1518707, this has been resolved in the porting set 8.9a.05 or later

Following might be some other reasons -

1. Older Java Version
2. Incorrect Classpath(possible duplicate values)
3. Might require apache service restart.

Hi Bhushan,

Performed all the steps but still there is same problem.

Thanks

the reason could be that his webtop profile is not pointing to the correct project model. you can go back and re-configure his profile and make sure that at the last step you click on the correct Project model. alternatively, delete the whole webtop profile and re-create making sure again to SELECT the correct project model.

Thanks to all!!!

Issue Resolved!

Hi Anand,

Please share the solution instead of closing the thread. It might help other people facing similar issues.

Created new profile and deleted existing in Webtop and it works !!!
