Re: jsf/Tomahawk - java.lang.ClassCastException: org.apache.xerces.jaxp.SAXParserFactoryImpl incompatible with javax.xml.parsers.SAXParserFactory error

My SystemOut.log contains these error. I look over all the jar files in
my app and only found this xmlparserv2.jar to be the only one that could
be causing the problem. But I'm still getting this same error even
after I removed this jar file from the app. I've spent two days on this
error. I must say Websphere/java is quite frustrating/waste of time
sometime. Sigh....

Lim: I am thinking that your log file should be getting populated

when you

start your WAS on the host side. Check in your IFS to see if you have

a log

file and if it getting populated.

/QIBM/UserData/WebSphere/AppServer/V6/Base/profiles/

The above is an example of the drill down to where the log files

should be

located at.

Hello,
I'm encountering a bit of a problem with jsf/tomahawk and hope

someone

can point me to the right direction.

In RAD, I've created a new test web project to use jsf and tomahawk

to

create a web app. Everything works well.

I then performed that same configuration steps to setup jsf/tomahwak

on

the actual (exisitng) web project that I'm supposed to develope my

apps

in. When I start the WAS6.1 server, I'm getting the following error

in

SystemOut.log:
[6/21/11 9:40:49:332 CDT] 00000016 Digester E
org.apache.commons.digester.Digester getParser Digester.getParser:
java.lang.ClassCastException:
org.apache.xerces.jaxp.SAXParserFactoryImpl incompatible with
javax.xml.parsers.SAXParserFactory


I'm assuming that this is caused by sometype of class conflict

between

the existing web app and jsf/tomahawk. My question is does anyone

know

how I can find out what jar files is causing this conflict?

Thanks
