BPM API in CE 7.2

Hi Guys,

I want to develop a custom java client that runs locally on my computer which reads the statistics of the processes & tasks periodically.

Is there any API that I can use to connect to my CE 7.2 server and read various statistics like process owner, process status and task status & current owner of the task etc in my application.

Do you guys know of any API to achieve this. All the blogs talk about BPM Reporting API that's available for CE 7.3 but that is not useful for me because I am working with CE 7.2 system.

Thanks in Advance,

PK
