Hi all,

I have a got a problem with opening Enterprise Services Builder, I'm able to Open ESB of PI Development system and got a problem with PI Quality system. I don't think this is the problem with Java.

I'm getting the below error after i entered User name and Password of ESB

Could not Initialize class com.sap.aii.ibrep.gui.xiitem.InternalXiItemServiceForTypeObjects

Internal problem occured(INTERNAL_PROBLEM)

Please help me in resolving this issue.
