I am trying a simple program in Java which would display Received Invite and Received Cancel when x-lite SIP client calls the SIP servlet and cancels the call respectively. My Java code is below. I am using Tomcat Mobicents SIP servlet - 

package org.example.servlet.sip;

import java.io.IOException;

import javax.servlet.ServletConfig;
import javax.servlet.ServletException;
import javax.servlet.sip.SipServlet;
import javax.servlet.sip.SipServletRequest;
import javax.servlet.sip.SipServletResponse;

public class SimpleServlet extends SipServlet {

public void doInvite(SipServletRequest request) {

System.out.println("*** Received INVITE ***");

try {
request.createResponse(SipServletResponse.SC_RINGING).send();
//request.createResponse(SipServletResponse.SC_OK).send();
} catch (IOException e) {
e.printStackTrace();
} 

}

public void doCancel(SipServletRequest request) {

System.out.println("*** Received CANCEL ***");

try {
request.createResponse(SipServletResponse.SC_REQUEST_TERMINATED).send();
} catch (IOException e) {
e.printStackTrace();
}

}


@Override
public void init(ServletConfig servletConfig) throws ServletException {
System.out.println("****** the simple sip servlet has been started ********* ");
super.init(servletConfig);
}
}

But when I run the servlet and attempt to make the call and then cancel, I dont see any of the println messages. But I do see SIP INVITES being received from my x-lite client. I have been to think about what might be going wrong but could get to a conclusion. Here are the console logs (Also observe the exception thrown when a cancel is received from the x-lite client). Appreciate your help.

First step would be to make sure that you have provided the container the correct DAR configuration. That means that your SipApplication is registered for INVITE and CANCEL messages.

You sent an INVITE to 1231@mobicents.org, which the container resolves as external ip address that is why you can see : "Dispatching the request event outside the container".

You can see that the container is trying to send your INVITE to the resolved ip address of Mobicents.org

from="127.0.0.1:5080" 
to="209.132.182.24:5060"

That is why you don't see your PRINTLN messages, this request is not meant to be for the container but for outside. From the logs you provided you can see also that the 180 RINGING never sent.

Seems that the SipSession never established and that is why when you try to CANCEL you get NullPointException.

What you need is to handle the requests inside the container.

Check on the CallBlocking example from Mobicents for some hints.

Let me know if i can help further.
