"Unable to figure out calledmethod of a caller pointcut"

[peterb]

I'm still experimenting with and learning AOP, so this might be one of those errors that's linked to my only partial understanding of the whole AOP thing.

What I would like to do is intercept calls to remote EJB objects. My first attemp resulted in:

<bind pointcut="execution(public * $instanceof{javax.ejb.SessionBean}->*(..))" >

which doesn't work at all. Now, I understand it correct that's because we're dealing with interfaces here and it's not possible to place pointcuts in there.

So my second attemp is:

<bind pointcut="call(* $instanceof{javax.ejb.EJBObject}->*(..))" >

Which works ok if I enter some data as argument. So for instance "int" instead of "..". But if I put ".." I get the following error:

java.lang.ExceptionInInitializerError
Caused by: java.lang.RuntimeException: java.lang.RuntimeException: Unable to figure out calledmethod of a caller pointcut
 at org.jboss.aop.ClassAdvisor.resolveCallerMethodInfo(ClassAdvisor.java:1262)
 at MyClient.<clinit>(HelloWorldClient.java)

I'm guessing that I either have too many wildcards in my pointcut expression for the system to handle or that there's some calls going on during initialisation that I am intercepting but don't want to. I tried solving that last problem by adding a "withincode" statement but the exception remains the same.

Can any one shed some light on the reason why things go wrong?

TIA

This looks like a bug on my end. I'll take a look next week when I'm finished with my JBoss training.

I too have the similar problem. It won't even accept non argument methods aas well.

sorry for the late response. With current CVS head I was able to write a unit test that had these pointcuts you described above with no problems. Maybe I have fixed something since Jun, I don't know.
