passing contract values to process from Java app.

I'm trying to start a process from a java program, but stumped on how I can pass the contract values over. The following code fails with

"Error while validating expected inputs: [Expected input [inputForm] is missing]"

But as you can see, the "inputForm" is indeed provided in the code.

Any thoughts oh wise ones?

Thanks again
