For what it's worth, I just had a successful EJB2 invocation over the servlet transport. In jboss-service.xml I have <mbean code="org.jboss.remoting.transport.Connector" | name="jboss.remoting:service=connector,transport=servlet" | display-name="Servlet transport Connector"> | <attribute name="Configuration"> | <config> | <invoker transport="servlet"> | <attribute name="dataType" isParam="true">invocation</attribute> | <attribute name="marshaller" isParam="true">org.jboss.invocation.unified.marshall.InvocationMarshaller</attribute> | <attribute name="unmarshaller" isParam="true">org.jboss.invocation.unified.marshall.InvocationUnMarshaller</attribute> | <attribute name="return-exception" isParam="true">true</attribute> | <attribute name="serverBindAddress">${jboss.bind.address}</attribute> | <attribute name="serverBindPort">8080</attribute> | <attribute name="path">unified-invoker/ServerInvokerServlet</attribute> | </invoker> | <handlers> | <handler subsystem="invoker">jboss:service=invoker,type=unified,transport=servlet</handler> | </handlers> | </config> | </attribute> | </mbean> | and in web.xml I have | <servlet> | <servlet-name>ServerInvokerServlet</servlet-name> | <description>The ServerInvokerServlet receives requests via HTTP protocol | from within a web container and passes it onto the ServletServerInvoker | for processing. | </description> | <servlet-class>org.jboss.remoting.transport.servlet.web.ServerInvokerServlet</servlet-class> | <!--init-param> | <param-name>invokerName</param-name> | <param-value>jboss.remoting:service=invoker,transport=servlet</param-value> | <description>The servlet server invoker</description> | </init-param--> | <init-param> | <param-name>locatorUrl</param-name> | <param-value> | <![CDATA[servlet://${jboss.bind.address}:8080/unified-invoker/ServerInvokerServlet/?dataType=invocation&marshaller=org.jboss.invocation.unified.marshall.InvocationMarshaller&return-exception=true&unmarshaller=org.jboss.invocation.unified.marshall.InvocationUnMarshaller]]> | </param-value> | <description>The servlet server invoker</description> | </init-param> | <load-on-startup>1</load-on-startup> | </servlet> | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4201207#...
