Class def not found in jboss as 7.X when using classloader for custom jar

[ddewashish]

I have a project structure as

eardirectory.Ear 
  lib/ 
    my-custom-classes.jar 
    ..... 
    ..... 
  my-custom-ejb.jar 
  META-INF/ 
  .... 

//Now I tried to load classes from classloader as 
ClassLoader cl = Thread.currentThread().getContextClassLoader(); 
clazz = Class.forName(my-custom-classes.class1.class.getName(), true, cl); 

Esper uses this way to load events type for pojo classes, but this will not work as current thread is of jboss and jboss has not any identification of my-custom-classes.jar.

So my question is how this can be done with jboss? I have to have to load class definition at runtime. Is there any way in "jboss-deployment-structure" I can define how to load classes before deploying EAR?

I also tried moving class definition from my-custom-classes.jar to my-custom-ejb.jar and loading class definition on to current thread, but this also didn't work.
