Hi!
I just want to give you some feedback concerning my trials to get a cocoon application
running under IBM Websphere 5.0 EE.
The main problem were broken redirects. Due to a hint from
someone expirencing similar troubles using jetty I found the following workaround:
Changing redirects from something like:
<map:match pattern="documents/index">
<map:redirect-to uri="index.html">
to:
<map:match pattern="documents/index">
<map:redirect-to uri="{request:contextPath}/documents/index.html"/>
seems to fix most of these problems.
Still it's probably not the most elegant solution, is it ?
----
Another issue was that WAS 5.0EE seems to want to use it's own version of the
xml-apis.jar and the xsltc.jar.
Removing both from the WEB-INF/lib directory seems to solve the worst errors
(java.lang.AbstractMethodError, etc.)
but there are still errors in error.log like:
ERROR (2003-02-03) 13:15.17:023 [core.xslt-processor]
(/vdt/vdtportal/sunspotdemo-portal-start) Servlet.Engine.Transports :
0/XSLTProcessorImpl: Cannot find the requested TrAX factory
'org.apache.xalan.xsltc.trax.TransformerFactoryImpl'. Using default TrAX
Transformer Factory instead.
Can this be savely ignored ?
----
While the application now seems to run, I still get errors like the following on the
console (nothing errors.log or core.log):

While this seems not to have any effect on the output, I still dont't feel very
comfortable about it.
And I have no idea what's going on here :-(
Any comments to this and also to the issues mentioned above are very welcome!
thanks,
Gernot.
