SerializationException trying to invoke very simple WebLogic web service

[mmeyer1963]

This completely baffles me. I hope one of y'all can help. It's probably something very simple, but I can't see it.

I've created a very simple web service in WebLogic:

package eborders.webservice.example;

import javax.jws.*;

@WebService
public class Example {
	@WebMethod
	public void process(String aString) 
	{
		System.out.println(aString + aString + aString);
	}
}

(Told ya it was simple.) Then I set up a bean, using values based on the WSDL WebLogic generates, that's supposed to invoke this service:

<bean id="webServiceBean"
         class="org.springframework.remoting.jaxrpc.JaxRpcPortProxyFactoryBean">
	<property name="serviceInterface" value="test.IWebService"/>
	<property name="portInterface" value="test.IRemoteWebService"/>
	<property name="wsdlDocumentUrl" value="http://localhost:7001/WebService/Example?WSDL"/>
	<property name="namespaceUri" value="http://test/example"/>
	<property name="serviceName" value="ExampleService"/>
	<property name="portName" value="ExampleSoapPort"/>
</bean>

However, when my Spring environment tries to invoke the service, I get a JAXRPCException ultimately caused by a SerializationException:

WARNING: Exception executing job: Could not connect to remote service [{http://test/example}ExampleSoapPort]; nested exception is java.rmi.RemoteException: Failed to invoke; nested exception is:

Can anyone give me any hints as to what I'm missing? Thanks in advance.

I forgot: I'm working with WebLogic Server 9.2.2 and Spring 2.0.7.

I encountered the same issue. Has anyone able to resolve this?
