Subject java.util.EmptyStackException in C2.1.3
Date Sat, 01 Nov 2003 11:46:25 GMT
Hi,

I am getting this error repeatedly in C 2.1.3  on Tomcat 3.3.1 final.
Same code worked fine on C2.0 .

The browser shows -

Internal Server Error
Message: null

Description: No details available.

Sender: org.apache.cocoon.servlet.CocoonServlet

logs show  java.util.EmptyStackException at SitemapSource.java:477

Any pointers/ideas greatly appreciated as we are really stuck here :-(
TIA,
Sandhu
