i've had this problem also...what i've found, though, is that the root error
will get logged into the tomcat/logs/servlet.log won't display in
the jboss log, that's the jsp exception...check your tomcat log to see if it
logged it there (my action classes always log a NPE to the tomcat log)...

Custom tags hiding JSP error messages


I was curious whether other people encountered this problem.  I've used tag
libraries before, and am currently using struts' template tag library.  I
have found that runtime JSP errors, such as null pointer exceptions, are
hard to debug because the custom tags "hide" the error message.  The only
message that usually comes up is a JSPException, which isn't really too
helpful.  Without custom tags, you get exact line numbers with exact errors
(NullPointerException).  Perhaps I'm doing something wrong.  Can anybody
give an opinion ?
