Shivam,

Add your classes with code similar to this:

config.getAppContext().put(EngineConstants.APPCONTEXT_CLASSLOADER_KEY,
yourclass.class.getClassLoader()); This sets the engine parent
classloader to your class.

another alternative is to just add to the cp like:

config.getAppContext().put(EngineConstants.WEBAPP_CLASSPATH_KEY,
"c:/jars/mjo.jar");
where the value is cp string and the config variable is the instance of
the EngineConfig.
