RE: Error message for xslt

Caused by: java.lang.NullPointerException

Are you setting all parameters used by the XSLT?  Can you verify you do?

Subject: Error message for xslt

I am doing transformation with XSLT and C2.2. When there's something wrong with the XSL, I get the following message:

javax.servlet.ServletException: org.apache.cocoon.ProcessingException:

Nothing tells me anything about the error message from the XSLT. Is there a way to know what is going on ??

Thank you.
