Working With Sockets Using A Single Thread

Question

Nokia phones appear to have a major problem with its J2ME implementation; access a socket with more than one thread causes the MIDlet to crash. After much thought I came up with a solution:
   private class Event {
     byte[] buffer;
    /** The event queue (yeah I know it is a stack) */
    Stack eventQueue = new Stack();
    /** The input stream */
    public DataInputStream sin;
    /** The output stream*/
    public OutputStream sout ;
    public void run() {
         while(running) {
          // send outgoing events
          while( running && sin.available() == 0 ) {
              while( !eventQueue.empty() ) {
               Event e = (Event)eventQueue.pop();
               sout.write( e.buffer );
               sout.flush();
              Thread.currentThread().yield();
          // process incoming events
    }But the flipping thing never goes into the "processing incoming events" section on real Nokia phones (works fine on the WTK thou). I'm guessing sin.available() is always returning 0.
Can anyone else think of a way round this (keeping in mind I don't know when data is coming, and read() blocks).

Answer 1

It sound like the while loop is locking out the socket read, almost like the yeild wasn't working. But you said teh threading was broken. Does a very short sleep help, is the shortest real timer interval 18.2 hertz = 55 millisecond?
