RE: [aspectj-users] catching container managed transactions
|
Hi
You are using an around advice:
void
around(Message m) throws Exception: handleException(m)
{
try
{
proceed(m);
}
catch(Exception
e)
{
System.out.println("Error here,guv "+e);
throw e;
}
}
the
alternativ is using an after advice with a throwing clause. That means that the
advice is only executed if your pointcut throws an
exception.
after() throwing:
mypointcut() {
//handle exception
here
}

Im not sure i follow, can you give a quick 1-liner example, or point me to
a relevant doco?
thanks.
Andrew

Hi
Why don't you use "after returning throwing" instead of
around advice.

Hi
I have a message driven bean which, inherently, throws an exception back to
the container to rollback jms messsages.
I want to be able to catch this exception, log something, and then let the
exception carry on.
I have a pointcut defined as follows:
pointcut handleException(Message m):
call (*
myBean.onMessage(Message)) && args(m);
With the advice being:
void
around(Message m) throws Exception: handleException(m)
{
try
{
proceed(m);
}
catch(Exception
e)
{
System.out.println("Error here,guv "+e);
throw e;
}
}
My question is two-fold:
1) Can we throw the exception like this and will the throw go back to the
container managed transaction??
2) Is this the right way to do this kind of thing? (im assuming not,
as the advice is marked as 'Not matched', but maybe this is one for the ajdt
guys.)
Sorry - im completely new to this stuff....
Regards,
Andy
