      i tried in 2 methods

       

      1. <property name="isolated">false</property>

       

      2. i created Jboss-app.xml and placed in META-INF

       

      <?xml version="1.0" encoding="UTF-8"?>

      <jboss-app>

      <loader-repository>

      org.myapp:loader=MyClassLoader

      <loader-repository-config>

      java2ParentDelegation=false

      </loader-repository-config>

      </loader-repository>

      </jboss-app>
