I've fixed this issue for Remoting release 2.2.2.SP8. org.jboss.remoting.marshal.MarshallerLoaderHandler, which is the ServerInvocationHandler for the classloader Connector, now is able to search org.jboss.mx.loading.HeirarchicalLoaderRepository3s, which allows it to find scoped classes. In order to make it possible to inform the MarshallerLoaderHandler about the HeirarchicalLoaderRepository3s to be searched, a section has been added to the MBean Connector definition. This section should be added to the Connector for which the "loaderport" parameter is defined. A client connected to such a Connector will be able to connect to the associated classloader Connector and download classes from any of the repositories listed in the section. For example, to allow an EJB3 to get scoped classes in an EAR where the jboss-app.xml is | <!DOCTYPE jboss-app PUBLIC "-//JBoss//DTD J2EE Application 1.4//EN" "http://www.jboss.org/j2ee/dtd/jboss-app_4_0.dtd"> | <jboss-app> | <loader-repository>jboss.remoting:loader=titan.ear</loader-repository> | </jboss-app> | the EJB3 Connector should look something like the following: | <mbean code="org.jboss.remoting.transport.Connector" | name="jboss.remoting:type=Connector,name=DefaultEjb3Connector,handler=ejb3"> | <depends>jboss.aop:service=AspectDeployer</depends> | <attribute name="Configuration"> | <config> | <invoker transport="socket"> | <attribute name="serverBindAddress">${jboss.bind.address}</attribute> | <attribute name="serverBindPort">3873</attribute> | <attribute name="loaderport" isParam="true">3883</attribute> | </invoker> | | <repositories> | <repository>jboss.remoting:loader=titan.ear</repository> | </repositories> | | <handlers> | <handler subsystem="AOP">org.jboss.aspects.remoting.AOPRemotingInvocationHandler</handler> | </handlers> | </config> | </attribute> | </mbean> | That is, the classloader Connector is informed about the HeirarchicalLoaderRepository3 with ObjectName "jboss.remoting:loader=titan.ear". An example case is attached to JBREM-962 "Remote classloading does not work with Isolated EARs". View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4159759#...
