Weblogic SimpleStatelessSessionProxyFactoryBean broken in 2.0m3

[smcardle]

Hi All,

Using Spring 2.0m3 my simple client (shown below) fails on WLS8.1 SP5. However, regressing back to Spring 1.2.5 it works just fine.


Client

public class EJBTestClient {
	
	private XmlBeanFactory factory;
	
	public EJBTestClient() {
		factory = new XmlBeanFactory(new FileSystemResource("applicationContext.xml"));
	}
	
	public static void main(String [] args) {
		
		EJBTestClient tc = new EJBTestClient();
		
		ServiceSelection ss = (ServiceSelection)tc.factory.getBean("serviceSelectionBean");
		try {
			System.out.println("result = " + ss.isValidCityOption("München"));
		}catch(Exception e) {
			e.printStackTrace();
		}
	}

}

applicationContext.xml

Good output from 1.2.5

log4j:WARN No appenders could be found for logger (org.springframework.beans.factory.xml.XmlBeanDefinitionReader).
log4j:WARN Please initialize the log4j system properly.
result = true

I have not found a similar issue here so I am assuming that not many people are currently using 2.0m3.

Not sure, but maybe there is a connection to this problem.

I don't think this is the same problem as I do not get class not found error information anywere.


All my test cases using deployed EJB's fail with the same error.

org.springframework.remoting.RemoteLookupFailureException: Failed to locate remote EJB [eSelfCare.ServiceSelectionHome]; nested exception is javax.naming.CommunicationException: null
javax.naming.CommunicationException [Root exception is java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is:

	at weblogic.jndi.internal.ExceptionTranslator.toNamingException(ExceptionTranslator.java:83)
	at weblogic.jndi.internal.WLContextImpl.translateException(WLContextImpl.java:390)

If this was a classloader error I would get a different problem reported.

Yes, the error would be different. It's just the circumstances that seem similar. Does this problem occur only with M3 or also with M1/M2?

Besides that: The serialization of arguments seems to be the problem. Does the error occur also for methods without arguments (and without return value)?

Hi Andreas,

Sorry its taken so long to get back to you but I have been on vacation for the last week or so.

Anyway, the same problem exists with M2 but I don't know about M1 as I never downloded that version. All seem fine with 1.2.5 & 1.2.6 (didn't download 1.2.7 either).

I will try it with the latest RC1 and see if the problem still exists thren repost here. If this is a problem with the 2.0 framework maybe it only affects WLS.

Regards

Steve

[smcardle]

OK,

So I just downloaded the M4 latest build and this works fine. It only seems that M2 & M3 are broken (possibly M1) in this respect.

Steve

[Andreas Senft]

I remember there has been an issue in Jira with ManagedProperties which should be fixed im M4. Maybe it has something to do with your problem.

Anyway, good that it works now

Regards,
Andreas
