Use JBoss AOP to do fault injection experiments

sergio.celentano Dec 16, 2010 11:21 AM

Hi all,

I am wondering if I can use JBoss AOP to modify "on the fly" methods input parameters.

I will explain better the scenario. I would like to conduct some robustness tests on a middleware used by an application deployed on JBoss. The middleware API are provided by a jar library file imported into the /lib folder of JBoss. My idea is the following: I'd like to intercept the calls of the middleware API methods made by the application and modify them submitting some "arbitrary" input values (and later see what happens).

I ran into the JBoss AOP framework and I want to know if it effectively matches my porpuse.

Thanks in advance for any feedback.

Kind regards,

Sergio

Sure. This will work. Do you have some specific interfaces that the calls you want to intercept belong to ? It sure makes it easier.
Also, are you using Java 1.5+ ? If so, the runtime weaving works well and is the most flexible. Otherwise, you will need to statically instrument and kick out an "instrumented" jar.

thank u Nicolas,
I am getting to know more abt this solution.
Yes, my library file foresees some interfaces from which all the other classes are derived and yes, I'm working in a java 1.5 fully compliant environment.
