RmiServiceExporter On WebLogic

[tpurcell]

Hello

I am trying to expose a Spring bean as a service via RMI using RmiServiceExporter. The bean is part of a Spring MVC app that will be deployed as a war on a Weblogic 9.x server. I am getting a connection refused exception (stack trace below).

Here's the exporter config:

<!-- RMI For Remote Access (Mule) -->
	<bean id="rmiEmployeeService" singleton="true" class="org.springframework.remoting.rmi.RmiServiceExporter">
		<property name="serviceName" value="EmployeeService"/>
		<property name="service" ref="employeeManager"/>
		<property name="serviceInterface" value="com.long.package.name.EmployeeManagerInterface"/>
		<property name="registryHost" value="localhost"/>
		<property name="registryPort" value="50770"/>
	</bean>

I'm guessing I need to do something in the Weblogic server to get this to work but I'm not sure what. Any help would be appreciated.

Thanks
Tom

Well I made some progress. I swithed to the JndiRmiServiceExporter and I can see the beans JNDI name in the server's JNDI tree. So I guess I'm in RMI but, by using JndiRmiServiceExporter, I let weblogic put me there instead of trying to do it myself.

Okay

I'm still stuck here. What I am trying to do is access a POJO from a MUle instance. I want Mule to be able to do a JNDI lookup and call a method on the POJO. I'm getting:

2007-05-21 18:54:57,717 ERROR [org.mule.impl.DefaultComponentExceptionStrategy] - Caught exception in Exception Strategy for: CreateEmployeeService60772: org.mule.umo.ComponentException: Failed to invoke org.springframework.remoting.rmi.RmiInvocationWrapper_921_WLStub. Component that caused exception is: CreateEmployeeService60772. Message payload is of type: com.chariotsolutions.soalab.crm.business.Employee
org.mule.umo.ComponentException: Failed to invoke org.springframework.remoting.rmi.RmiInvocationWrapper_921_WLStub. Component that caused exception is: CreateEmployeeService60772. Message payload is of type: com.chariotsolutions.soalab.crm.business.Employee
	at org.mule.impl.DefaultLifecycleAdapter.intercept(DefaultLifecycleAdapter.java:223)
	at org.mule.impl.InterceptorsInvoker.execute(InterceptorsInvoker.java:47)
etc.....

I realize a most of what is in the error referes to Mule. I've posted there too but I thought I'd try here casue I'm desperate.

Do I need to run weblogic.rmic on my beans to make this work? I have debug turned on but is are there any other troubleshooting tips?

Thanks
Tom
