TimeTrex Time and Attendance

I want to have some integration between a Java back office application and TimeTrex, I would like to have the ability to push and pull data.
Can someone give me some basic general advise or suggestions on the best way to accomplish this. Are there any links with examples.
Is anyone interested / available to assist/work (with compensation) with a Java programmer on this?

Thanks!!

You can use the APIs do this, check the api/soap/api_client_example.php file.
