BEA Weblogic SIP server

Bea server is a old SIP servlet container ie application server which is used to embed control logic in a program.

1. Install Bea Weblogic

2. Follow the Installation steps

Make domain

3. Goto the installation directory . Usually C:/bea/user_projects/mydomain/ .

click on startweblogic.cmd in windows. In case the system is linux run startweblogic.sh script

4. Open Web console on url : http://127.0.0.1:7001/console. Enter username password

default username password weblogic , weblogic .

It can also be customized for example my username and password are altanai , tcs@1234

5.  Make Converged SIP Servlet Application in any editor such as notepad , edit+ etc .

The project structure looks like

Call screening
src
build
src
web
build.xml

The SIP servlet are put side directory structure of src. For example : sample application for Call screening :

package com.altanai.voice;

import java.io.IOException;
import javax.servlet.*;
import javax.servlet.sip.*;
import javax.servlet.sip.Proxy;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import java.util.*;

public class CallScreening extends SipServlet{

private static SipFactory factory;
private static SipApplicationSession sas;
private static Proxy proxy;

public void init(ServletConfig config) throws ServletException{
	System.out.println("Call screening SIP servlet initiated");
	super.init(config);
}

protected void doInvite(SipServletRequest req) throws java.lang.IllegalArgumentException,java.lang.IllegalStateException,javax.servlet.ServletException,java.io.IOException{
	System.out.println("Received an Invite Request");
	if(req.getFrom().toString().indexOf("alice")!=-1){
		req.createResponse(406).send();
		System.out.println("User is blocked");
	} else {
		req.createResponse(200).send();
		System.out.println("User is not blocked");
	}
}
}

6. Build it with ant . For this go inside the application folder and run ant. Output will either be “failed to build “ or “build successfully” .

The ant  command generates the war file from SIP servlet Web application .

7. Incase of successful build . Add the application to Weblogic web console install section and activate it.

I will demonstrate this process in step by step manner . First  click on “ Lock and Edit “ Button on the left panel . Then goto Install button in the centre area and browser to the location of application war or sar we have build through ant ,

8. We can delete an application in exactly the same way . click on “ Lock and Edit “ Button on the left panel . Then goto the delete button after selecting the radio button alongside the application we want to delete.

8. For enhanced application building we can also refer to sample provided along with bea weblogic . file:///C:/bea/sipserver30/samples/sipserver/examples/src/index.html

It is supported on jdk1.5 hence the system’s environment variables must match. Otherwise in later stages deploying applications throw class version error.
