Question : Need some help resolving Tomcat Java Error (Unrecognized Windows Sockets error: 0: JVM_Bind)

I am trying to run a web application on Tomcat 5. Getting a java.net.SocketException. Google search seemed to indicate that this may be due to another application using a port that Tomcat server is trying to use. I changed the port to 50000 range, and still get the same error:

Mon Jul 19 16:53:00 CDT 2010: Starting to listen to port 50002

Answer : Need some help resolving Tomcat Java Error (Unrecognized Windows Sockets error: 0: JVM_Bind)

your catalog.Engine is trying to open a port. 50000 range is too high.
Try changing it to 4000
