Catching LazyInitialization exception within an aop Interceptor
Setup
1.JBoss AS 4.2.0 GA
2.EJB 3 persistence layer of data Model.
3.UI that calls a Delegation layer that JNDI lookup and returns EJBs back to UI
The Idea
1. To write an Interceptor that intercept calls of form
"my.persistence.*->get*()".
2. Try to invoke the Called Method
3. Catch LazyInitialization exception
4. If caught, Persist Target Object and Invoke Called Method with the new
attached Target Object
Problem
Though I can see that LazyInitialization is thrown, it is never getting caught
within the Interceptor.
Help
will be greatly appreciated...
Code
>aop>
>bind pointcut="call(* com.my.proj.persistence.*->get*())">
>interceptor class="com.proj.aop.MyInterceptor"/>
>/bind>
>/aop>
try {
methodInvocation.getCalledMethod().invoke(methodInvocation.getTargetObject(),
methodInvocation.getArguments());
} catch (LazyInitializationException ex) {
// do things
}
OR
try {
methodInvocation.invokeNext();
} catch (LazyInitializationException ex) {
// do things
}
