I know you said SCJP and SCWD were not welcome but I have to tell you that I am SCJP, SCWCD certified. Besides that, I have a bunch of other certifications which allow me to say I am very experienced on certification test. I also have taught SCJP preparatory courses and created study material for that. So, although I am not OCPJP certified, I am very familiar with certification objectives and surely I would be able to create the sample code you need.
