Cpu usage raise to 100% in socketchannel read

Question

hello guys,
i m developing one socket applicatoin in which multiple client are connected to one server socket channel..
now in my application there is one main thread which runs continuesly and in which i m asking to one particular client for his action....
now when i ask to client then after one another thread which read from the client socketchannel is started and continuously running until client not reply.
this read thread raise my cpu usage to 100%.....
so what to do.????
overview of my code::::
//first thread
void run()
askClient();
//start receive reply thread here
rrt = new RRT();
rrt.start();
//second thread run method
void run()
while(running)
System.out.pritnln("Inside receive thread");
while(Bytesread==socketchannel.read(buf) > 0)
//if get reply stop this thread
running = false;
in this second thread until client not reply cpu usage raise to 100%
I have try for sleep in second thread run method than also it is not able to stop raise in usage..
what should i do ....

Your designs demands artificial blocking reads, so why not using blocking sockets anyway? After all, you've spawned a new thread just to read that, you might as well save yourself the trouble with selectors.
On the other hands, you might want to do the right thing (TM) and switch to a non-blocking design. I side with ejp on this one, use the documentation and the web.
