Not that I know of any, but forget that site - many complaints about not receiving payment. If I were you, I'd try googling around or searching in the Mining software board.
No - "Java scrypt mining, Why?"
You have a perfectly good cpuminer at your disposal from multiple mirrors/source repos all around the web (Java's a notoriously terrible work process for mining).
WeMineLTC has a miner you can use on their site under "Getting Started" at the bottom of the page. Compare your CPU's performance with pooler's cpuminer. While DrH's Bitminter client runs from a Java environment, its only to run the GUI - all the actual work done is through either OpenCl etc for a GPU or through your chip's firmware (i.e. 'Antminer work process' for Bitmain chips).
