Hi all ! please help me with my problem.

This is the scenario.
I have a database for bio metric logs, and I want to display the picture of anyone who logs using bio-metrics in my page.
I tried doing a java thread to run in background, in my thread is an unlimited loop which is querying the latest log in my database(don't worry my database and device are real time synced) but it failed.
I guess it failed because the java thread return type is void, when I called the method in my Action class it didn't refresh the page.

I guess my idea is hopeless, How will I be able to do it?
 
Consider Paul's rocket mass heater.
