LocalSlsbInvokerInterceptor, Websphere 5.1 IllegalArgumentEx

[markstg]

I am running Spring 1.0.2 on Websphere 5.1 and using the LocalSlsbInvokerInterceptor for an EJB proxy.

I am receiving an IllegalArgumentException when the interceptor invokes the EJB local.

Config:

<bean id="myService" class="org.springframework.ejb.access.LocalStatele ssSessionProxyFactoryBean">
<property name="jndiName">
<value>java:comp/env/mySessionFacadeEjb</value>
</property>
<property name="businessInterface">
<value>com.mycompany.domain.service.MyBusinessServ ice</value>
</property>
</bean>

Stacktrace:

--------------------


Note: I noticed the following in the interceptor:

public Object invoke(MethodInvocation invocation) throws Throwable {
EJBLocalObject ejb = null;
try {
ejb = newSessionBeanInstance();
return invocation.getMethod().invoke(ejb, invocation.getArguments());
}
catch (InvocationTargetException ex) {
Throwable targetException = ex.getTargetException);
logger.info("Method of local EJB [" + getJndiName() + "] threw exception", targetException);
if (targetException instanceof CreateException) {
throw new AspectException("Could not create local EJB [" + getJndiName() + "]", targetException);
}
else {
throw targetException;
}
}
catch (Throwable ex) {
throw new AspectException("Failed to invoke local EJB [" + getJndiName() + "]", ex);
}

. . .



The interceptor creates the new EJB instance (EJBLocalObject) then reflectively tries to invoke the method.

When debugging the above, I noticed the variable 'ejb' in the code is actually Websphere generated classes... i.e.


/**
* EJSLocalStatelessMySessionFacade_5f717edd
*/
public class EJSLocalStatelessPerscriptionSessionFacade_5f717ed d extends EJSLocalWrapper implements org.albertawellnet.pin.service.MySessionFacadeLoca l { . .


Since this class extends MySessionFacadeLocal.. it should be of the same type. I am passing in a single java.lang.String as an argument, so I dont think it should be a matter of invalid number or type of Parameters.


Anyone else having a problem using the LocalSlsbInvokerInterceptor using Websphere 5.1 ??

I noticed Colin had a problem that was kinda similar? But I think that was a matter of trying to use the LocalSlsbInvokerInterceptor accessing a Remote and not Local EJB..


Any thoughts / advice are appreciated

Looks like the container generated classes do NOT implement the Business Interface... obviously a problem with the invoke.

Now, to figure out how to get WSAD to carry over the Business Interface into the signatures...
