Detection for of Running Services on Remote Computer using Java

Is there a way to detect running services on a client machine using Java? I need to detect a specific running application and it's status (enabled or disabled) and execute something on my application once the running service is detected and enabled.

A little research on my part has come to extent that I ha开发者_开发知识库ve 2 options:

1. Applet and use Sigar-API.
2. VBScript to access client specific process via markup language (HTML).

This alone I think could solve the detection of the service, yet the real problem is detecting its status (enabled or disabled).

Could you use system calls to the underline OS? something like this but using 'ps'?
