Swing GUI and Multithreading

Dear All,

I have gui, data starts flowing as soon as Connect button is press. Coz of
mulitthreading gui get freeze.

private class ConnectionThread

implements Runnable

{

public void run()

{

try

{

System.out.println("In ConnectionThread Run Method");

OiJsshEngine sshEngine = new OiJsshEngineImpl(getOptions());

OiJsshConnection sshConnection = sshEngine.getSSHConnection();

OiJsshStreamFilter filter = null;

filter = new OiJsshStreamFilterImpl("#");

filter.setUI(txtData);

filter.setPatternMatcherStream(System.err);

filter.setPatternMismatchStream(System.out);

OiJsshStreamWriterThread writerThread = new
OiJsshStreamWriterThread(sshConnection.getOutputStream());

writerThread.start();

sshConnection.execShell();

}

catch(Exception e)

{

System.out.println(e);

}

}



private void cmdConnectActionPerformed(ActionEvent evt)

{

cnn = new ConnectionThread();

Thread t = new Thread(cnn);

t.setDaemon(true);

SwingUtilities.invokeLater(t);

}

What alternative can i work on.

Thank in advance for the pointers.

Regards,
Ketan
