Selenium RC - grid hub is not listening

I'm new to selenium. I am running an existing selenium RC code. When i try to launch the hub I got the following error

Unable to locate tools.jar. Expected to find it in C:\Program Files\Java\jre6\lib\tools.jar Buildfile: build.xml does not exist! Build failed

So I downloaded JDK files. Then I changed the system variables Now it is pointing to

C:\>echo %JAVA_HOME%
C:\Program Files\Java\jdk1.7.0_11

C:\>echo %PATH%
c:\ruby\bin;C:\ant\bin;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C
:\Program Files\Windows Imaging\;C:\Program Files\Common Files\Roxio Shared\DLLS
hared\;C:\Program Files\Java\jre1.6.0_05\bin;C:\Program Files\Java\jdk1.7.0_11

C:\>echo %ANT_HOME%
C:\ant\bin\ant.bat

I ran the following bat file to launch the hub - launch hub.bat

title Hub
cd C:\selenium\Grid\selenium-grid-1.0.4
c:\ant\bin\ant launch-hub

OUTPUT

C:\selenium\Grid\selenium-grid-1.0.4>c:\ant\bin\ant launch-hub
Buildfile: build.xml

My training document says I should • Wait to see the ‘started Socket Connector’ statement and ‘44’;

But I didn't get it. I think it is because of failed SocketConnector. Please help me to fix it.

These lines tells you that the port 4444 is already opened by another process

 [java] 2013-01-16 14:45:25.364::WARN:  failed SocketConnector @ 0.0.0.0:4444
 [java] java.net.BindException: Address already in use: JVM_Bind

You should check what this process could be and shut it, or modify your build.xml to change the port on which the hub is to start

Use netstat -an on Windows

NOTE : If you've run your ant file multiple times, the process that opened the 4444 port is maybe the same that you're trying to launch, which has no yet be terminated.
