Hi All

I am deploying 5.16.3 Activiti-explorer on WAS 7.0. I am able to login and browse through tasks. But when I click on Processes navigation button I get the below error and my left nav is all empty except an image of wheel repeated about 10 times in 10 rows. This is in firefox.

Any suggestions and thoughts on how to fix this?

Thanks
Praveena
