Question

I am trying to build a simple desktop application where the user enters the url in a text field and clicks on the submit button to send the GET request for that page.I am trying to open a socket to connect to the host in the submit button mouse clicek event handeler but the GUI gets stuck. I have to close it from task manager.

private void SubmitButtonMouseClicked(java.awt.event.MouseEvent evt)  
{

  Socket s = null;  
  String website = URLTextBox.getText();  
  String host = "111.65.23.56";    //this could be any host  
  int port = 80;  

  try  
  {  
   System.out.println("I am opening socket");  
   s = new Socket(host,port);   **// the code stuck here :(**   
   System.out.println("socket opened");  
  }  
  catch(IOException e){ }  

  // and the code follows......  

}

please help me out…..

You’ll almost certainly want to create a separate thread for the Socket code, and most likely using the excellent Socket Selector family of classes:
