Hi I ran this, I did everything as is in here http://scn.sap.com/community/bi-platform/blog/2014/11/25/how-to-create-a-program-file-in-bi4#comment-613074 which is basically just to create a jar file and do minimal configuration for the schedule. I created the jar as runnable and utility jar, I packaged/extracted the included jars and left them out. I tried all those ways and I put in the Program Parameter the class name "ExecuteExtract" but I still get the error

Failed to load class: [ExecuteExtract]. Reason: [java.lang.ClassNotFoundException: ExecuteExtract].

Does anyone have an idea on what I am missing?

Either use the default package, or specify the fully qualified class name (com.ghc.bo.extract.ExecuteExtract) as the class name in the Program Object parameters.
