RE: Problems using LookUp Dispatch Action
Posted by David Friedman <hu...@ix.netcom.com>.
If your class extends LookupDispatchAction, why isn't your own class named
in the stacktrace below? It looks like it is invoking a regular
LookupDispatchAction. Also, you can lookup code online to find the
offending line (just copy it into an editor which has line number so you can
check out line 233. Just substitute the 1_2_9 with your own working version
of Struts:
http://svn.apache.org/viewvc/struts/struts1/tags/STRUTS_1_2_9/src/share/org/
apache/struts/actions/LookupDispatchAction.java?view=markup
(warning: that line will wrap so you'll have to paste it together before
changing the STRUTS_1_2_9 part to your own in-use version of Struts)
Regards,
David
