Subject cocoon (2.0.3) on websphere 5?
Date Fri, 14 Feb 2003 10:56:38 GMT
Hi

After playing with the settings in websphere, i have finally managed to
deploy my cocoon in the websphere app server. Most cocoon standard demo
works except the jsp generator and reader stuff. I have changed the jsp
engine setting to use the ibm one in cocoon.xconf and it seems to be picking
up the right jsp engine but I keep on getting an exception when I hit the
demo jsp link:

org.apache.cocoon.ProcessingException: Exception JSPReader.generate():
java.lang.ClassCastException:
org.apache.xerces.parsers.StandardParserConfiguration 


The following is the stack trace:

I have read somewhere that we might need to patch the app server up
regarding to Xerces. I was given this e-fix PQ69817 number but I could not
find it on IBM site. Has anyone managed to get cocoon running on websphere
serving jsp pages?
