Hi All
I am trying to build a player servlet using JSR 309 with SIPServlet.
Code is like this (code example of JSR309)..
package basic;
public class PlayerServlet extends SipServlet
{
protected MediaSessionFactory mediaSessionFactory;
private MyNetworkConnectionListener networkConnectionListener;
protected MyPlayerListener playerListener;
protected URI prompt;
@Override
public void init() throws ServletException
{
super.init();
try {
MscontrolFactory mscFactory = MscontrolFactory.getInstance();
// create the Media Session Factory
mediaSessionFactory = mscFactory.createMediaSessionFactory(null);
}
catch (MscontrolException e)
{
throw new ServletException(e);
}
networkConnectionListener = new MyNetworkConnectionListener();
playerListener = new MyPlayerListener();
// Could use a static property to set the prompt, or some signalling
parameter (like annc in RFC 4240)
prompt = URI.create("http://localhost:8080/media/prompt.wav");
}
........more code
}
When i am running the the code i am getting the error as follow.
I am using the Sailfin server.
