I want to execute a specific method which contains a service call. As it includes a service call , it will take some time for execution. I want to add a timer which will keep program in wait till that method completes its executiuon. Any work around for this?

You can organize an asynchroneous method execution with a timeout with java.util.concurrent package
ExecutorService executorService = ...
Object res = executorService.submit(new Callable<Object>() {
public Object call() throws Exception {
... your logic
}
}).get(timeout, TimeUnit.MILLISECONDS);

Could be specified that
.submit() actually returns a Future and that there is a .get() without a timeout tooi was trying this solution and even these classes (ExecutorService , futute etc) are not allowed on client side of GWT. There are restrictions on the use of classes on client side. It gives error - No source code is available for type java.net.URL; did you forget to inherit a required module?

Well, ExecutorService and others are part of standard JRE since 1.5
You can use a separate thread to call that service and using join() method of Thread class, you can force main program to wait until that thread finishes the execution.
Sheduler
Scheduler.get().scheduleDeferred(new Scheduler.ScheduledCommand(){
@Override
public void execute() {
// code here
}
.get(). For further information, look at the javadoc ofFutureandFutureTask.
