WAD Java-Call Failed

Hi

I'm using WAD 7 and when I try to save a webtemplate I get this error:

<i><b>Java-Call Failed: Call XMLVALIDATION abandoned (1). Check BI Portal Conne

Java-Call Failed: Call VALIDATION abandoned (1). Check BI Portal Connecti</b></i>

The webtemplate is saved anyway, but always get this error message.

Can you tell me what should I do?

Thanks
