Description

When using the servicemix jboss deployer with JBoss 4.2.2 there is a conflict between the xercesImpl jar in <jboss>/lib/endorsed and the xerces and xml-api's in many of the Servicemix components. When using servicemix with jboss, this results in a stack trace similar to:

http://www.nabble.com/file/p16140526/DeploySharedException.txt

and the problems described in this thread:

http://cwiki.apache.org/SM/discussion-forums.html#nabble-to15306485|a15306485

The following components are pulling in xml-apis (xml-apis-1.3.04.jar) and xercesImpl:

+ /deployables/sharedlibraries/
servicemix-shared

And also (via a transitive dependency from shared) its being pulled into the following components

+ /deployables/bindingcomponents/
servicemix-file servicemix-http servicemix-truezip target
servicemix-ftp servicemix-jms servicemix-xmpp

+ /deployables/serviceengines
servicemix-cxf-se servicemix-lwcontainer servicemix-script
servicemix-bean servicemix-drools servicemix-wsn2005
servicemix-eip servicemix-quartz servicemix-jsr181 servicemix-saxon

The fix is just to add the xerces and xml-api's exclusion to servicemix-shared/pom.xml

 <dependency>
      <groupId>org.apache.servicemix</groupId>
      <artifactId>servicemix-soap2</artifactId>
      <exclusions>
         <exclusion>
           <groupId>xml-apis</groupId>
           <artifactId>xml-apis</artifactId>
         </exclusion>
         <exclusion>
           <groupId>xerces</groupId>
           <artifactId>xercesImpl</artifactId>
         </exclusion>
       </exclusions>
    </dependency>

I've verified that as both the xml api jars are also below <servicemix>/lib this change shouldn't have any negative affects. Also, this will reduce the footprint of the distribution by about 20mb

I think instructions above should be sufficient to make change. Let me know if you want svn diff output and I will attach.
