Ok, so I am a Java newbie and have a quick question. I have created a custom class to be called in the GCF. I have been able to compile it, jar it and have deployed it in the correct locations. My only issue is actually calling it from the XML < CALL >. I tried < CALL a:class="classname" > and < CALL a:class="com.campuspipeline.sso.authenticator.custom.classname" > and got cpipconnector errors that said it could not find the class. What would the path to the class be? Any help is appreciated and please forgive my ignorance. I am learning as I go.

Thank You,
Bill
