The aim of this tutorial is to show how it's possible to embed OpenOffice.org in a java application without using OfficeBean or OOoBean.

First step : compilation of nativeview.dll.
-> copy nativeview.c in the parent directory of your .class nativeview.class.
-> generate nativeview.h using javah -jni Directory.NativeView
-> rename method of NativeView.c using names of NativeView.h
->Create a release Visual C++ project
--> Add NativeView.h, NativeView.c, jni.h, jni_md.h, jawt_md.h, jawt.h to project.
(jni.h, jni_md.h, jawt_md.h, jawt.h can be founded in java directory)
--> Make Compilation.
--> copy nativeview.dll in the parent directory of your .class nativeview.class.
-->copy awt.dll, java.dll, jawt.dll, jvm.dll, verify.dll (witch can be founded in java directory) in the same directory that nativeview.dll

Second step: write your classes.
this is an example of a java.awt.panel witch contain OpenOffice
Code:

public class OOoTest extends Panel{

   private static final long serialVersionUID = 1L;

   private NativeView nativeView;   
   private OOoTest2    oooFrame;
   
   public OOoTest(Container parent) throws Exception{
      
      // setVisible necessaire pour le nativeView
      // setFocusable necessaire pour le nativeView
      this.setVisible(true);
      this.setFocusable(true);
      
               parent.setName("OOoFrame");
            
      // composant open office
      nativeView = new NativeView();
      parent.add(nativeView);
      parent.setSize(800,600);
      nativeView.setVisible(true);
      nativeView.setSize(800,600);

      // initialisation du composant OpenOffice
      oooFrame = new OOoTest2(nativeView,parent.getName());
      oooFrame.createFrame();
      oooFrame.loadDocument("private:factory/swriter");

   public void close(){
      System.err.println("fermeture de la AWT_FRAME");
      try {
         // fermeture de la connexion et de la xFrame
         oooFrame.shutdown();
      } catch (Exception e) {
         e.printStackTrace();
      }
   }
}


Code:
public class OOoTest2 {
   

   public OOoTest2(NativeView vueNative, String frameName) throws Exception{
      nativeView = vueNative;
      
                ..........make connect!
      XMultiComponentFactory xMCF =....
      
      xMultiServiceFactory =.....
      
      xComponentContext = ......
      
      xDesktop = .....
      nativeView.setVisible(true);
   }
   
   
   public void createFrame() throws Exception{
      
      xFrame = (XFrame)UnoRuntime.queryInterface(XFrame.class,
            xMSF.createInstance("com.sun.star.frame.Frame"));
      
      xToolkit =(XToolkit)UnoRuntime.queryInterface(
            XToolkit.class,xMSF.createInstance("com.sun.star.awt.Toolkit") );
      
      // initialise le xChildFactory
      XSystemChildFactory xChildFactory =(XSystemChildFactory)UnoRuntime.queryInterface(
            XSystemChildFactory.class, xToolkit);
      
      Integer handle = nativeView.getHWND();
      short   systeme = (short)nativeView.getNativeWindowSystemType();
      byte[]  procID = new byte[0];
      
      
      xWindowPeer = xChildFactory.createSystemChild((Object)handle,procID, systeme);
      
      xWindow = (XWindow)UnoRuntime.queryInterface(XWindow.class,xWindowPeer);
      
      xFrame.initialize( xWindow );
      
      XFramesSupplier xTreeRoot =(XFramesSupplier)UnoRuntime.queryInterface(
            XFramesSupplier.class,xDesktop );
      
      XFrames xChildContainer = xTreeRoot.getFrames();
      xChildContainer.append(xFrame);
      
      xWindow.setVisible(true);
      xFrame.setName(XFrameName);
      xWindow.setVisible(true);
   }
   
   public void loadDocument(String url) throws Exception{
      // xComponentLoader qui permet de charger un document
      XComponentLoader xComponentLoader = (XComponentLoader)UnoRuntime.queryInterface(XComponentLoader.class, xDesktop );
      // on charge le document et on récupère le xComponent
      xComponent =  xComponentLoader.loadComponentFromURL(url,xFrame.getName(),FrameSearchFlag.CHILDREN, null);
      // initialisation du xModel
      xModel = (XModel)UnoRuntime.queryInterface(XModel.class, xComponent);
      // initialisation du xController
      xController = xFrame.getController();
   }
   
   public void save(String url) throws IOException{
      if (xController != null || xModel !=  null){
         XStorable xStore = (XStorable)UnoRuntime.queryInterface(
               XStorable.class,xModel);
         xStore.storeToURL(url,null);
      }
      else {
         // erreur
      }
      
   }

   public void shutdown() throws Exception {
      // disable nativeView
                nativeView.setVisible(false)
      // close the connection
      if (connexion!=null){
         System.out.println("femeture de la connexion");
         connexion.closeConnection();
      }
   }            
}

I succeded in using nativeview.dll with the DeskView example showed in Developer's Guide chapter 6. At the beginning I used this kind of local connection

String remoteOfficeUrl="uno:socket,host=192.168.35.119,port=2002;urp;StarOffice.ServiceManager";
Object initialObject = xUrlResolver.resolve(remoteOfficeUrl);

...


and everything works. Hovewer, If I tryed to use a remote connection, that's the OpenOffice serve is on another pc, no Writer Gui is showed...
I wonder wether it's possible to use nativeview.dll to connect to a remote server.
Could anyone help me?
thanks a lot
bye
Filippo
