any known issues with WAS 4.0?
Hi,
I am new to Struts and installed Struts-example, Struts-blank etc from the
stable 1.1 release at jakarta.apache.org/struts.
None of these work on my WAS 4.0. I get all sorts of errors and I dug
through news groups applying patches that never worked all of yesterday
trying to get one of them to work.
Then, I installed the struts-stub (struts 1.0) example from the tutorials on
the site and that one deployed perfectly. Does Struts 1.1 just not work on
WAS 4.0? On struts-blank I get
Error 500:
through the web -- no error context provided on the line
index.jsp::<logic:redirect forward="welcome"/>
The activity log reports:

There are several jar files you need. struts.jar is one of them, but
there are many commons- jars as well. Also, for Struts 1.1 apps to
work, you need some Xerces jars. Namely, xmlParserAPIs.jar and
xercesImpl.jar. We're using them from the latest Xerces (2.5) on WAS
5.0, but any recent Xerces should work.
It definitely seems that whatever XML parser WAS has installed isn't
sufficient for Struts 1.1. In WAS 5.0, it does seem sufficient for
Struts 1.0, though, so that could explain what you're seeing.
Finally, you should be able to restart your web-app or app server and
watch the stdout logs for Struts' startup messages. With your "detail"
and "debug" parameters set the way your web.xml shows, you should get
plenty of logging messages to give you some ideas what is failing on
startup.
