как получить доступ к Lotus базе из Java
привет. использую стандартный код из хелпа:
import lotus.domino.*;
public class platform implements Runnable
{
Database db;
public static void main(String argv[])
{
Thread nt = new Thread((Runnable)t);
nt.start();
}
public void run()
{
try
{
Session s = NotesFactory.createSession(host, user, pwd);
db = s.getDatabase("myserv1/mydom","test\\calendar.nsf");

.....

}
catch (Exception e)
{
e.printStackTrace();
}
}
}

все это тестируется на IBM RAD 6.0.1 + Apache Tomcat 4.1
и в консоли появляется :

java.lang.NoClassDefFoundError: lotus/domino/local/NotesReferenceQueue
at lotus.domino.NotesThread.checkLoaded(Unknown Source)
at lotus.domino.NotesThread.initThread(Unknown Source)
at lotus.domino.NotesThread.run(Unknown Source)


пути прописаны в notes.ini
JavaUserClasses=D:\Program Files\lotus\notes\data\domino\java\NCSO.jarr;D:\Program Files\lotus\notes\jvm\lib\ext\Notes.jar
и ServerTasks=http,diiop прописал.
незнаю куда дальше копать, подскажите, пожалуйста

как получить доступ к Lotus базе из Java
The following examples demonstrate the minimal code needed for a Java program that uses the Domino classes. The examples instantiate a Session object and print the String output of its getPlatform method (Platform property).

1. This is an application that makes local calls and extends the NotesThread
class:

public class platform1 extends NotesThread
{
  public static void main(String argv[])
    {
        platform1 t = new platform1();
        t.start();
    }
  public void runNotes()
    {
    try
      {
        Session s = NotesFactory.createSession();
        // To bypass Readers fields restrictions
        // Session s = NotesFactory.createSessionWithFullAccess();
        String p = s.getPlatform();
        System.out.println("Platform = " + p);
      }
    catch (Exception e)
      {
        e.printStackTrace();
      }
    }
}

2. This is an application that makes local calls and implements the Runnable interface:

        finally
        {
            NotesThread.stermThread();
        }
    }
}


4. This is an agent program where the code is entered through the Domino Designer UI. The UI generates everything in the example except the two lines following // (Your code goes here).

    catch (Exception e)

            String p = s.getPlatform();
            PrintWriter pw = getAgentOutput();

        catch (Exception e)
        {
            e.printStackTrace();
        }

}

7. This example demonstrates an application that makes remote (IIOP) calls. The example requires the user to enter the name of the host Domino server and optionally a user name and password. If a user name and password are not supplied, the server must allow anonymous access.

           "Need to supply Domino server name");
        return;
      }
      platform6 t = new platform6(argv);
      Thread nt = new Thread((Runnable)t);
      nt.start();
    }
  public platform6(String argv[])
  {
    host = argv[ 0 ];
    if(argv.length >=  2 ) user = argv[ 1 ];
    if(argv.length >=  3 ) pwd = argv[ 2 ];
  }
  public void run()
    {
    try
      {
        Session s = NotesFactory.createSession(
                    host, user, pwd);
        String p = s.getPlatform();
        System.out.println("Platform = " + p);
      }
    catch (Exception e)
      {
        e.printStackTrace();

8. To enable SSL in the previous application example, replace:

        Session s = NotesFactory.createSession(
                    host, user, pwd);
With:
        String args[] = new String[ 1 ];
        args[ 0 ] = "-ORBEnableSSLSecurity";
        Session s = NotesFactory.createSession(
                    host, args, user, pwd);

TrustedCerts.class (typically in domino\java in the data directory of the server) must be on the classpath. This file is generated by the DIIOP task when it starts.
In order to enable SSL for an applet, you should also enable the attribute "Applet uses CORBA SSL Security" in the "Java Applet Properties" dialog.

9. This example demonstrates an applet that makes Domino calls. AppletBase makes the calls locally if possible, remotely otherwise.

import lotus.domino.*;
public class foo extends AppletBase
{
  java.awt.TextArea ta;
  public void notesAppletInit()
  {
    setLayout(null);
    setSize( 100 , 100 );
    ta = new java.awt.TextArea();
    ta.setBounds( 0 , 0 , 98 , 98 );
    add(ta);
    ta.setEditable(false);
    setVisible(true);
  }
  public void notesAppletStart()
  {
    Session s = null;
    try
    {
      // Can also do openSession(user, pwd)
      s = this.openSession();
      if (s == null) { //not able to make connection, warn user
        ta.append("Unable to create a session with the server");
        return;
      }
      String p = s.getPlatform();
      ta.append("Platform = " + p);
    }
    catch(Exception e)
    {
      e.printStackTrace();
    }
    finally
    {
      try {this.closeSession(s);}
      catch(NotesException e) {e.printStackTrace();}
    }
  }
}
10. This example demonstrates an applet that makes Domino calls in code that responds to an AWT event. Because the AWT event handler is a separate thread, you must explicitly initialize and terminate a Domino session if the code is running locally, and must not if the code is running remotely (IIOP).
