title: Refreshing a JTable in a client/server application
body: <p>I developed a Java client/server application, communicating via Spring RMI, the Client is symply a swing Jframe how containing at the top a command buttons(add, update, delete), in the middle a JTable, and at the bottom, a form.</p>
  
  <p>the server side contains simply a Dao layer by using iBatis witch communicates with an Apache Derby database.</p>
  
  <p>So the application works greatly, but two problems are found :</p>
  
  <p>1) when the user A adds/updates/deletes a row from a JTable, the others can't see the changes until clicking a button to refresh the data in the JTable, I wanna that this changes must be done automatically.</p>
  
  <p>2) when the user A wants to update a row in the JTable, and the user B wants to changes the same row, when done, always teh programme keeps the last data saved.</p>
  
  <p>can some one give a working code ? or a link to a website, tutorial ....</p>
