How to deploy a JCO Server????

Question

Hello Experts!
I have written a JCO Server by using the Netweaver Developer Studio. Now I want to deploy this JCO Server on our SAP XI Server. The aim of this should be to create a connection between ABAP and JAVA to send data from JAVA to ABAP.
The RFC connection already exists and is working. What I don't know is how to deploy my JCO Server and how to start this JCO Server from our XI Server. I hope anybody could help me.
Thanks in advance!!!
Greetings Alexander
Here is the source code of my JCO Server:
public class JCOServer implements JCO.ServerExceptionListener, JCO.ServerStateChangedListener {
  static public class Repository extends JCO.BasicRepository implements IRepository {
    public Repository(String name)
      super(name);
  protected static IRepository repository;
  static {
    repository = new Repository("TestRepository");
    JCO.MetaData fmeta = new JCO.MetaData("ZEJB_TEST_ZUGRIFF");
    fmeta.addInfo("REQUTEXT", JCO.TYPE_CHAR, 255,   0,  0, JCO.IMPORT_PARAMETER, null);
    fmeta.addInfo("ECHOTEXT", JCO.TYPE_CHAR, 255,   0,  0, JCO.EXPORT_PARAMETER, null);
    fmeta.addInfo("RESPTEXT", JCO.TYPE_CHAR, 255,   0,  0, JCO.EXPORT_PARAMETER, null);
    repository.addFunctionInterfaceToCache(fmeta);
  static public class Server extends JCO.Server {
    public Server(String gwhost, String gwserv, String progid, boolean isUnicode, IRepository repository)
      super(gwhost,gwserv,progid,repository);
       this.setProperty("jco.server.unicode", isUnicode?"1":"0");
    protected void handleRequest(JCO.Function function)
      JCO.ParameterList input  = function.getImportParameterList();
      JCO.ParameterList output = function.getExportParameterList();
      JCO.ParameterList tables = function.getTableParameterList();
      System.out.println("handleRequest(" + function.getName() + ")");
      System.out.println("Anfrage vom SAP-Server: " + input.getString("REQUTEXT"));
      if (function.getName().equals("ZEJB_TEST_ZUGRIFF")) {
        output.setValue(input.getString("REQUTEXT"),"ECHOTEXT");
        output.setValue("Das ist eine Antwort von JCOServer","RESPTEXT");
   JCO.Server srv[] = new JCO.Server[1];
  public JCOServer()
     JCO.addServerExceptionListener(this);
     JCO.addServerStateChangedListener(this);
  public void startServers()
    srv[0] = new Server("vxi1","sapgw00","BEAN",true,repository);
    for (int i = 0; i < srv.length; i++) {
try {
srv.setTrace(true);
srv.start();
catch (Exception ex) {
System.out.println("Konnte Server nicht starten: " + srv.getProgID() + ":
" + ex);
      }//try
    }//for
  public void serverExceptionOccurred(JCO.Server server, Exception ex)
    System.out.println("Ausnahme in Server " + server.getProgID() + ":
" + ex);
    ex.printStackTrace();
  public void serverStateChangeOccurred(JCO.Server server, int old_state, int new_state)
    System.out.print("Server " + server.getProgID() + " hat den Status geändert von [");
    if ((old_state & JCO.STATE_STOPPED    ) != 0) System.out.print(" GESTOPPT ");
    if ((old_state & JCO.STATE_STARTED    ) != 0) System.out.print(" GESTARTED ");
    if ((old_state & JCO.STATE_LISTENING  ) != 0) System.out.print(" HORCHEN ");
    if ((old_state & JCO.STATE_TRANSACTION) != 0) System.out.print(" TRANSAKTION ");
    if ((old_state & JCO.STATE_BUSY       ) != 0) System.out.print(" BESCHÄFTIGT ");
    System.out.print("] nach [");
    if ((new_state & JCO.STATE_STOPPED    ) != 0) System.out.print(" GESTOPPT ");
    if ((new_state & JCO.STATE_STARTED    ) != 0) System.out.print(" GESTARTED ");
    if ((new_state & JCO.STATE_LISTENING  ) != 0) System.out.print(" HORCHEN ");
    if ((new_state & JCO.STATE_TRANSACTION) != 0) System.out.print(" TRANSAKTION ");
    if ((new_state & JCO.STATE_BUSY       ) != 0) System.out.print(" BESCHÄFTIGT ");
    System.out.println("]");
  public static void main(String[] argv)
    JCOServer obj = new JCOServer();
    obj.startServers();

Hello Alexander,
congratulations to the invention of the wheel....
Now, what do you think is the function of the application server itself? what you do here is to put a shell around JCO and then try to run it from another shell. Why not just use it from your program?
I recommend to do some of the examples with JCO and then see what  the difference on this is.
