  1. POCrash and unexpected output when using Java sip servlets
    text
    copied!<p>I am trying a simple program in Java which would display <strong><em>Received Invite</em></strong> and <strong><em>Received Cancel</em></strong> 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 - </p> <pre><code>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); } } </code></pre> <p>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. </p> <pre><code>2011-02-25 18:39:09,574 INFO [SIPTransactionStack] (Mobicents-SIP-Servlets-UDPMessageChannelThread-12) &lt;message from="127.0.0.1:4264" to="127.0.0.1:5080" time="1298677149492" isSender="false" transactionId="z9hg4bk-d8754z-2c7c09d1c301b688-1---d8754z-" callId="OGU2ODE5ZWU1OGI0N2JiZDI4ZDU3MzdkNzBiYTA2NWQ." firstLine="INVITE sip:1231@mobicents.org SIP/2.0" &gt; &lt;![CDATA[INVITE sip:1231@mobicents.org SIP/2.0 Via: SIP/2.0/UDP 127.0.0.1:4264;branch=z9hG4bK-d8754z-2c7c09d1c301b688-1---d8754z-;rport=4264;received=127.0.0.1 Max-Forwards: 70 Contact: &lt;sip:mobicents@127.0.0.1:4264&gt; To: &lt;sip:1231@mobicents.org&gt; From: "mobicents" &lt;sip:mobicents@mobicents.org&gt;;tag=4ca712e5 Call-ID: OGU2ODE5ZWU1OGI0N2JiZDI4ZDU3MzdkNzBiYTA2NWQ.
