I am trying to deploy my web application on jboss-6.0.0Final, which is currently deployed on apache tomcat.
I have two jars one that contains same package which is org.apache.axis. I am putting one jar in <Jboss-home>/server/default/lib & another jar in <my-app-war>WEB-INF/lib.
It is required to put both jars in the class path. No way to remove one of the jar. So I need to keep both jars. & It is giving me following error
java.lang.ClassCastException: org.apache.axis.attachments.AttachmentsImpl cannot be cast to org.apache.axis.attachments.Attachments
at org.apache.axis.AxisFault.makeFault(AxisFault.java:101)
at org.apache.axis.client.Call.invoke(Call.java:1828)
I think it is due to conflict of same classes in two different jars.
Now, I want to know the way by which I can force jboss to load classes of this particular package from axis.jar exist in /WEB-INF/lib.
How can I do that?

Explode your war,
In your Exploded WAR web-inf directory add this xml file: jboss-classloading.xml
with content:
(domain is your war name)
<classloading xmlns="urn:jboss:classloading:1.0"
name="mywar.war"
domain="mywar_domain" <!-- (domain is your war name) -->
parent-domain="Ignored"
export-all="NON_EMPTY"
import-all="true">
</classloading>
I'll share quite simple and straight forward process which I had followed when I came across same situation.
1> Create a jboss-web.xml file.
<class-loading java2classloadingcompliance="false">
<loader-repository>
com.rts:archive=DTH_PROD.war
<loader-repository-config>
java2ParentDelegation=false
</loader-repository-config>
</loader-repository>
</class-loading>
</jboss-web>
Points:,
- Begin the xml with tag which is not visible in the code I'm posting
Check 3rd line of above code,
- com.rts - This is your package name.
- DTH_PROD.war - Name of bundle you wish to keep
2> Now place this xml file into WEB-INF directory of your project and voilla!!
