The problem I reported to the list the other day (that error) in JBoss 2 w/
Tomcat 3.2b7 is actually the same issue as this. Granted, I haven't actually
tested this in WebSphere, but it is the same issue and others have tried it
with success IIRC.
Anyway, the problem is (as others have previously reported), the JASPER
version used by the WebSphere servlet engine is not up to the latest spec
and as such does not support the way the Form tag is currently written. If
you like, I can attach an updated Struts.jar that has the fix compiled and
ready to go. If you want to change it yourself, here's the code:
(This fix was suggested by David Janovy)
In doEndTag on the Form tag, change:
pageContext.removeAttribute(Constants.BEAN_KEY,
PageContext.REQUEST_SCOPE);
pageContext.removeAttribute(Constants.FORM_KEY,
PageContext.REQUEST_SCOPE);
To:
pageContext.getRequest().removeAttribute(Constants.BEAN_KEY);
pageContext.getRequest().removeAttribute(Constants.FORM_KEY);
pageContext.removeAttribute(Constants.BEAN_KEY);
pageContext.removeAttribute(Constants.FORM_KEY);

Subject: Struts 1.0 on WebSphere 3.5.4??
Has anyone been able to get Struts 1.0 to work on WebSphere
3.5.4 (yes, that's with the new patch 4)?
I can get index.jsp to run, but I'm not getting farther
than that. I've made the recommended DTD changes, but that
didn't help (no ActionMapping, or similar, errors have
shown up in the log.) What I'm looking to find out is if I
need to go through the additional process of modifying the
Struts code as was declared necessary for 3.5.2 and
below.
Any ideas? Thanks for your help!!!!
The following is the reported error:
