I have a servlet that starts a thread, and I want that this servlet waits for a condition that the thread has to change.

SERVLET

Thread t1 = new Thread1();
t1.start();
//wait until available = true and then continue


THREAD1 extends Thread
private boolean available = false;
public Thread1(){
}

public void run(){
//...
available = true; //notify to servlet that can continue
//...
}



How can I do this?

Thanks for all.
