load: class query not found in the service PZ21_TC in integrated ITS

Hi Experts,

In the portal which displays the service PZ21_TC in integrated ITS we are getting a page like "Enter some file attributes" with message 'Please wait. You will automatically be forwarded. This page had to be included for technical reasons.'

This is getting displayed while we click on a browse button which was supposed to open a dialog box for selecting file from the PC.

In the bottom we are also getting a message "load: class query not found".

Anyone experienced such a problem before.

Any valuable suggestion will be rewarded.

Thanks & Regards,

Soumya.
