Hello All,
I have *.war* file.File name is '*test.war*'.
I am trying to deploy it on *JBOSS-6.0.0-xxxx-CR1* by isolating classloader for it since I am getting an exception along with stack trace as follows:
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

I have observed that it is because of *commons-collections-3.2.1.jar * in *web-inf\lib* is conflicting with *commons-collections-3.2.jar* which is present in the *default\deployers\jsf.deployer\MyFaces-2.0\jsf-libs*
* *
To remove this exception I have decided to load isolated classloader for my* .war* file.
I searched , read discussions,forums regarrding it and I have taken following steps.
1. Created *-jboss-classloading.xml* and placed it in WEB-INF
WEB-INF\ jboss-classloading.xml
contents :
+ <?xml version="1.0" encoding="UTF-8"?>+
+ <!--See http://phytodata.wordpress.com/2010/10/21/demystifying-the-jboss5-jboss-classloading-xml-file-- http://phytodata.wordpress.com/2010/10/21/demystifying-the-jboss5-jboss-classloading-xml-file-->+
+ <classloading xmlns="urn:jboss:classloading:1.0"+
+ name="test.war" +
+ domain="DefaultDomain"+
+ parent-first="false"+
+ top-level-classloader="true"+
+ export-all="NON_EMPTY"+
+ import-all="true">+
+ </classloading>+
+
+
2. Created -*jboss-web.xml* and placed it in WEB-INF
WEB-INF\ jboss-web.xml
Contents:
+<?xml version="1.0" encoding="UTF-8"?>+
+ <jboss-web>+
+ <class-loading java2ClassLoadingCompliance="false">+
+ <loader-repository>+
+ com.mastek:archive=test+
+ <loader-repository-config>java2ParentDelegation=false</loader-repository-config>+
+ </loader-repository>+
+ </class-loading>+
+ </jboss-web>+
3. Created - *jboss-app.xm*l and placed it in WEB-INF
WEB-INF\classes\META-INF\jboss-app.xml
Contents :
+<?xml version="1.0" encoding="UTF-8"?>+
+ <jboss-app>+
+ <loader-repository>com.mastek:loader=emhada</loader-repository>+
+ </jboss-app>+
I took above mentioned steps but *still that exception occurs*.
Please throw some light on this .So I Can solve this isolation of ClassLoader successfully.
