Thanks for your help, but that does not work.

I'm not using Apache Forrest. So I tried your 1). But my webapp still does not work; same ClassCastException occures again. What I actually did was copying the xercesImpl.jar and the xml-apis.jar to from %TOMCAT_5.0.28%/common/endorsed to %TOMCAT_5.5.7%/common/endorsed. In Tomcat 5.5 there are no comon/endorsed libs any more, so that could be a reason, but wasn't. And I copied %TOMCAT_5.0.28%/common/endorsed/*.jar (there are only the two jars mentioned above) to %TOMCAT_5.5.7/webapps/myWebApp/WEB-INF/lib, but that does not work, either.

Trying to solve the problem this way (including additional xml parser libs to the webapp and bloat the resulting WAR file) seems to me not to be a good way to go, because every user with Struts and JDK 5.0 and Tomcat 5.5 had to include additional jars to their webapp. Therefor it would be better to solve the problem by change Struts' behavior to respond adequately to the new JDK, new Tomcat or whatever the bug is evoked by. This implicates that there are lots of JDK 5/Tomcat 5.5 users of course, but I think this is the case or at least a matter of time ;-)

Any other ideas now?

Hi Luis.
I'm sorry for not giving this info to you.
Yes, I use JDK 5.0. update 1. The webapp is developed with this jdk and

both, Tomcat 5.0.28 and Tomcat 5.5.7, use this jdk, too. The webapp works on Tomcat 5.0.28, but does not work on Tomcat 5.5.7.

What else could be the problem?

Did you upgrade your jdk to version 5.0?

Hi.

I have a problem migrating to Tomcat 5.5 with my Struts webapp.

I run my webapp with Struts 1.2.4 on Tomcat 5.0.28. Everything works
fine. But when I move the same webapp to a Tomcat 5.5.7 I get a
ClassCastException with message
"org.apache.struts.taglib.logic.IterateTei" whenever I try to send a
request to my webapp.

Started to solve this problem four weeks ago I waited for new Struts Releases (the problem occured with Struts 1.1 four weeks ago) and

tried

to run it with Struts 1.2.4 now. It does not work. Then I tried
different 5.5.x Tomcat versions (5.5.5, 5.5.6 and now 5.5.7). It does
not work, either. Then I posted this problem two weeks ago to Apaches
Bugzilla ( http://issues.apache.org/bugzilla/show_bug.cgi?id=33664 ),
but perhaps that was not the right place, because nobody noticed that
posting there.

Is Bugzilla the right place for something like this? If it is, how

long

does it take to get an answer? If it is not, is this mailing list the
right place? If it is not, please tell me where I can get help. If it
is, please have a look at this problem and help me fixing it.

Thanks a lot so far,
 Bernd

I had a similar problem with jdk 5.0, but with tomcat 5.0.28. In that case
I was using Apache Forrest (as a webapp). Under my Struts webapp I put
Apache Xerces (the latest version) under WEB-INF lib, because it seems
that the parser under jdk 5.0 is buggy (it should be an old version of
Xerces...) then it does not parse correctly tlds.
Now:
1) if you do not use Apache Forrest, try putting libraries from Apache

2) if you use Apache Forrest, undeploy the Forrest webapp and restart the
