How can I mimic user operation while machine is locked

I have created a program in java which will emulate user activity in windows operating system (like clicking left mouse button), but as soon as I lock my system the activity also stops.

开发者_如何学JAVAIs there any way to keep it running.

Let me know if any more details are required....

If it's browser based activity, try Selenium, which you can use to send mouse clicks, and many other events to a browser. Link to Selenium site

A good scripting language to automate (emulate) all kinds of windows tasks is AutoIT. It's comes with good documentation & is easy to learn!
