[opencms-dev] weird null pointer exception

Sun Mar 13 19:18:26 CET 2011

If I'm reading the stack trace correctly, it looks like the exception
itself is occurring in your companyhead.jsp, on line 212 of the expanded
version.  You'll find expanded jsps in your opencms webapp folder under
/WEB-INF/jsp(/Offline/system/modules/etc/etc/etc), which should help you
correlate that line number to the actual line of code in your template.
