Deploying a simple sip servlet
Indra
I am new to mobicents , I am currently working on a project which uses
mobicents sip-servlet on Jboss server.
I use SIP inspector as my user agent . everything works fine when i
deploy and run the code on the server, when i send invite call from
sip inspector and try to trace from wire shark , I getting an error
stating ''400 BAD Request''
This is my code from my editor
package org.example.servlet.sip;
import java.io.IOException;
import java.text.ParseException;
import javax.servlet.*;
import javax.servlet.sip.*;
import javax.servlet.ServletConfig;
import javax.servlet.ServletException;
import javax.servlet.sip.SipServlet;
import javax.servlet.sip.SipServletRequest;
import javax.servlet.sip.SipErrorListener;
import javax.servlet.sip.SipServletRequest;
import javax.servlet.sip.SipServletResponse;
import javax.servlet.sip.Proxy;
public class ServletZigbee extends SipServlet{
protected void doInvite(SipServletRequest request)
throws ServletException, IOException
{
if(request.isInitial())
{
Proxy proxy = request.getProxy();
proxy.setRecordRoute(true);
proxy.setSupervised(true);
proxy.proxyTo(request.getRequestURI());
}
System.out.println("ServletZigbee: Got request:\n" +request);
}
public void doMessage(SipServletRequest request)
throws ServletException, IOException
{
SipServletResponse res = request.createResponse(200);
res.send();
}
public void init(ServletConfig config) throws ServletException {
super.init(config);
System.out.println("Servlet SIP / Zigbee deployed!");
}
}
Now i have to write a code using the method doMessage()
so that I can send message request to my sip inspector.
Can anyone guide me with this . It would be a great help !
Thanks

could you please explain what you want to do with your servlet?
By the way, as Jean daid it before your log level is too high; If you use Jboss_mobicents go to the jboss-log4j.xml file and change gov.nist and org.mobicents categories to DEBUG.
You can find this file here : $JBOSS_HOME/server/default/conf

Hello Jean ,
This is the following error that I get . I am using SIP inspector as my SIP user agent and I am using invite and Message SIP messages, When i run my server and trace in wireshark, i get the following error in my server console

for the To header from RFC 3261:
To = ( "To" / "t" ) HCOLON ( name-addr
/ addr-spec ) *( SEMI to-param )
Looks like the semicolon should only be present if followed by a parameter.

I am trying to deploy a SIP servlet on Jboss server. I am using SIP inspector as my user agent . My task is to send an invite message from my SIP UA to my server and after that I need to trace in wireshark for 200 OK message. When i try to do this, i am getting as BAD Message
This is my servletzogbee.java
<-- INVITE
--> MESSAGE
And i have given 2 calls from the UA before I start the WIRESHARK.
My local IP address is my PC IP address and with different port
and my remote IP address is the default JBOSS server address :127.0.0.1 & default remote server port : 5080
thank u
Yvon Colin
I think what you want is really simple :
With sip inspector you send an invite to your "Jboss AS"! Cool
But your Jboss AS doesn't know what to do if you didn't code it before.
What you want back, if have understand, is a 200 ok response , right?
Your doinvite methode means (what your "Jboss as" should do when it receives an invite). In your case you juste need a 200 ok response. so, you have to code your doinvite methode like that :
public class ServletZigbee extends SipServlet{
protected void doInvite(SipServletRequest request)
throws ServletException, IOException
{
if(request.isInitial())
res.send();
}
}
}
that's all for what you want.

But the problem is, as far as i know i guess sip servlet should have an init() method. I tried as you said, but now i get ICMP message. Destination unreachable ! sad :(
co-ordinator of mine suggested me to re-write few things in the SIP header , like by adding a Route :<sip:local_ip:local port>
The main task of mine is to manage incoming and outgoing SIP messages, If i am done with this, I can carry on with further tasks in my project. But this seems like struggling because of that BAD MESSAGE earlier and now with ICMP destination unreachable

I am agree with you should have an init method, what i wrote was just the doinvite methode (you should have a doinvite and an init). But are you sure that your servlet is deployed? And if it is deployed, did you configure the DAR file? Without that the container can't send your invite to your simple servlet.

I will check with it now. But I have a question !
I use SIP inspector as my UA and i input a simple invite & message methods. Do I have to change anythng in the SIP header manually ?

I deleted the To tag ; as you suggested.
Now Do i have to write method for ACK also in my Sipservlet.java class? before running ?
Thanks,
-Indhira
Andrew Miller
The ACK should have a tag on the To: line. It should be the tag that was returned in the 200 OK.
The notation you showed early for SIP Inspector looks very similar to SIPp. If this is so, [peer_tag_param] should resolve to this for the ACK.
Try the line as originally given in the ACK (but not in the INVITE.
To: <sip:1000@[remote_ip]:[remote_port]>;[peer_tag_param]
See http://tools.ietf.org/html/rfc3261 for details of how the tags work. Look at the INVITE transaction sections.
You only need to write a handler for the ACK if you need to do something with the ACK.
In your example the INVITE has an SDP offer, so the 200 should have the SDP answer. In this case the ACK simply completes the INVITE transaction, and all the relevant handling is done for you by the stack.
If the INVITE had no SDP, then the offer would be in the 200, and the SDP answer would be in the ACK. In this case you normally need to handle the ACK to deal with the SDP.

org.mobicents.servlet.sip.core.dispatchers.DispatcherException: the Request-URI does not point to another domain,
and there is no Route header,the container should not send the request as it will cause a loop. Instead, the container must reject the request with 404 Not Found final response with no Retry-After header. You may want to check your dar configuration file to see if the request can be handled or make sure you use the correct Application Router jar.

and YVON of you suggested me to config with the DAR file , But i cannot find that Configuration file in the jboss-5.1.0.GA/server/default/conf directory. now my question is , can we configure manually ?? or should i need to install any other version of mobicents ??
This is the mobicent version , which i use
http://mobicents.googlecode.com/svn/downloads/sip-servlets-eclipse-update-site/
-Thank you
Andrew Miller
The DAR is held at jboss-5.1.0.GA\server\default\conf\dars\mobicents-dar.properties.
It is best not to edit this by hand. It can be configured from http://localhost:8080/sip-servlets-management/. If your servlet is deployed correctly, it should be available in drop down box under INVITE.
Try working through the tutorial that Yvon posted, it seems to cover the basics.

Thanks a lot ! I found it atlast , I didn't check the Runtime environment path, i edited the DAR file by adding
MESSAGE: ("org.mobicents.servlet.sip.example.SimpleApplication", "DAR:From", "ORIGINATING", "", "NO_ROUTE", "0")
Now everthing works fine without errors, but I get 501 Request no Implemented message in my wireshark.
I read the tutorail already, That was the link provided by my co-ordinator, it helped me, but My goal is to send MESSAGE to the servlet , not Invite. Hope you understan my question. If i try to send a message from Servlet to SIP UA, it works fine, but the other way round, I am getting a server failure.
Thank you
-Indhira
Andrew Miller
If you are still using your original code then you should use "org.example.servlet.sip.ServletZigbee" (I believe), rather than "org.mobicents.servlet.sip.example.SimpleApplication".
It is better to do this from the Web interface, because you can see if your Servlet is deployed, and you can't make a typographical error.

It is almost done do what Andrew said go to the : http://localhost:8080/sip-servlets-management/.
Or if your know your servlet name. I think you konw it 'cause you code it replace "org.mobicents.servlet.sip.example.SimpleApplication", by your servlet name. I think you probably know it DAR means Default Application Router. Your question is What for? "The Application Router is called by the container to select a SIP servlet application to service an initial request".
You select the wrong servlet and unfortunatly this servlet does not handle message that why you have that kind of error. here you can see the code of the servlet you did call in you dar file there is no domessage method in it or a dorequest method.

Many Thanks for your support so far, finally my SIP UA communicates with my sip servlet.
I just replaced the "org.mobicents.servlet.sip.example.SimpleApplication'' with my class name and now it works. and send 200 ok message .
Its a better progress in my project now. Any questions, i will post it . Thank you Guys !
