Hi,

I've configured ExternalConfig as follow:

<mbean code="org.jboss.naming.ExternalContext"
 name="jboss.jndi:service=ExternalContext,jndiName=external/fs">
 <attribute name="JndiName">external/fs</attribute>
 <attribute name="Properties">
 java.naming.factory.initial=com.sun.jndi.fscontext.RefFSContextFactory
 java.naming.provider.url=file:///D:/JBoss/jboss-5.1.0.GA
 </attribute>
 <attribute name="InitialContext">javax.naming.directory.InitialDirContext</attribute>
 <attribute name="RemoteAccess">false</attribute>
</mbean>

InitialContext iniCtx = new InitialContext();
 Context c = (Context) iniCtx.lookup("external/fs");
 System.out.println(c);
