Class AllocateServerSocketServlet

java.lang.Object
  javax.servlet.GenericServlet
      javax.servlet.http.HttpServlet
          org.pentaho.di.www.BaseHttpServlet
              org.pentaho.di.www.AllocateServerSocketServlet

All Implemented Interfaces:

Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig, CarteServletInterface

public class AllocateServerSocketServlet
extends BaseHttpServlet
implements CarteServletInterface

This servlet allows a client (TransSplitter in our case) to ask for a port number.
This port number will be allocated in such a way that the port number is unique for a given hostname.
This in turn will ensure that all the slaves will use valid port numbers, even if multiple slaves run on the same host.
