Asterisk 11 outbound calls using AMI with java

Hi ,
I would like to initiate a call from extension number to another in LAN network. I have done this task through FreePBX GUI. Now I am trying to execute this task by using Asterisk AMI with java code. Below java code shows some exception while in debugging.

[code]import java.io.IOException;

import org.asteriskjava.manager.AuthenticationFailedException;
import org.asteriskjava.manager.ManagerConnection;
import org.asteriskjava.manager.ManagerConnectionFactory;
import org.asteriskjava.manager.TimeoutException;
import org.asteriskjava.manager.action.OriginateAction;
import org.asteriskjava.manager.response.ManagerResponse;

public class HelloManager
{
private ManagerConnection managerConnection;

public HelloManager() throws IOException
{
ManagerConnectionFactory factory = new ManagerConnectionFactory(
“192.168.68.173”, “admin”, “admin”);

this.managerConnection = factory.createManagerConnection();
}

public void run() throws IOException, AuthenticationFailedException,
TimeoutException
{
OriginateAction originateAction;
ManagerResponse originateResponse;

originateAction = new OriginateAction();
originateAction.setChannel(“SIP/1010”);
originateAction.setContext(“default”);
originateAction.setExten(“2020”);
originateAction.setPriority(new Integer(1));
originateAction.setTimeout(new Integer(30000));
// connect to Asterisk and log in

managerConnection.login();

// send the originate action and wait for a maximum of 30 seconds for Asterisk
// to send a reply
originateResponse = managerConnection.sendAction(originateAction, 30000);

// print out whether the originate succeeded or not
System.out.println(“Enter Response=”+originateResponse.getResponse());

// and finally log off and disconnect
managerConnection.logoff();
}

public static void main(String[] args) throws Exception
{
HelloManager helloManager;

helloManager = new HelloManager();
helloManager.run();
}
} [/code]
