Package org.acplt.oncrpc.apps.jportmap

Class jportmap

java.lang.Object
org.acplt.oncrpc.server.OncRpcServerStub
org.acplt.oncrpc.apps.jportmap.jportmap
All Implemented Interfaces:
OncRpcDispatchable
public class jportmap extends OncRpcServerStub implements OncRpcDispatchable
The class jportmap implements a Java-based ONC/RPC port mapper, speaking the widely deployed protocol version 2.

This class can be either used stand-alone (a static main is provided for this purpose) or as part of an application. In this case you should check first for another portmap already running before starting your own one.

  • Field Details

    • locals

      public InetAddress[] locals
      List of IP addresses assigned to this host. Will be filled later by constructor.

    • servers

      public Vector servers
      The list of registrated servers.

    • PMAP_PORT

      public static final int PMAP_PORT
      Well-known port where the portmap process can be found on Internet hosts.
      See Also:

    • PMAP_PROGRAM

      public static final int PMAP_PROGRAM
      Program number of the portmapper as defined in RFC 1832.
      See Also:

    • PMAP_VERSION

      public static final int PMAP_VERSION
      Program version number of the portmapper as defined in RFC 1832.

  • Constructor Details

    • jportmap

      public jportmap() throws OncRpcException, IOException
      Create a new portmap instance, create the transport registration information and UDP and TCP-based transports, which will be bound later to port 111. The constructor does not start the dispatcher loop.
      Throws:
      OncRpcException - in case of an RPC error.
      IOException - in case of an IO error.

  • Method Details

    • dispatchOncRpcCall

      public void dispatchOncRpcCall(OncRpcCallInformation call, int program, int version, int procedure) throws OncRpcException, IOException
      Dispatch incomming ONC/RPC calls to the individual handler functions. The CALLIT method is currently unimplemented.
      Specified by:
      dispatchOncRpcCall in interface OncRpcDispatchable
      Parameters:
      call - The ONC/RPC call, with references to the transport and XDR streams to use for retrieving parameters and sending replies.
      program - the portmap's program number, 100000
      version - the portmap's protocol version, 2
      procedure - the procedure to call.
      Throws:
      OncRpcException - if an ONC/RPC error occurs.
      IOException - if an I/O error occurs.

    • main

      public static void main(String[] args)
      Create an instance of an ONC/RPC portmapper and run it. As we have to bootstrap the ONC/RPC port information chain, we do not use the usual overloaded run() method without any parameters, but instead supply it the transports to handle. Registration and deregistration is not necessary and not possible.
      Parameters:
      args - An array containing the command line arguments.
