Open MS documents into JFrame [closed]

Question

What I get is to open a Microsoft (Word, Excel, etc) into a JFrame.

Anybody can tell me some to get this library?, the Apache POI API (http://poi.apache.org) can help me with this?, maybe the library JACOB (http://danadler.com/jacob/)?

Answer 1

Apache POI is a good and strong library. I used it several times and it really helped me.

Answer 2

But be prepared, Apache POI can not even read all sorts of information in a Microsoft document. I have many files from our customers, POI do not processed correctly. So you should test sufficient.

Answer 3

All right!, this is my solution (Using Eclipse SWT) to open a MS Word document into a jframe:

import java.awt.Canvas;
import java.io.File;

import javax.swing.JFrame;

import org.eclipse.swt.SWT;
import org.eclipse.swt.SWTError;
import org.eclipse.swt.awt.SWT_AWT;
import org.eclipse.swt.browser.Browser;
import org.eclipse.swt.events.SelectionAdapter;
import org.eclipse.swt.events.SelectionEvent;
import org.eclipse.swt.layout.FillLayout;
import org.eclipse.swt.layout.GridData;
import org.eclipse.swt.ole.win32.OLE;
import org.eclipse.swt.ole.win32.OleClientSite;
import org.eclipse.swt.ole.win32.OleFrame;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.FileDialog;
import org.eclipse.swt.widgets.Menu;
import org.eclipse.swt.widgets.MenuItem;
import org.eclipse.swt.widgets.Shell;


public class AbrirWordJFrame {
    static OleClientSite clientSite;
    static OleFrame frame;

    public static void main(String[] args) {
        final Display display = new Display();
        final Shell shell = new Shell(display);

        JFrame jframe=new JFrame("Mi jframe");
        final Canvas canvas=new Canvas();
        jframe.getContentPane().add(canvas);
        jframe.setSize(800, 600);
        jframe.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        jframe.setVisible(true);

        display.asyncExec(new Runnable() {
            public void run() {
                Shell shell = SWT_AWT.new_Shell(display, canvas);
                shell.setSize(800, 600);

                //abrimos un word
                shell.setText("Word Example");
                shell.setLayout(new FillLayout());
                try {
                    frame = new OleFrame(shell, SWT.NONE);
                    //esto abre un documento existente
                    clientSite = new OleClientSite(frame, SWT.NULL, new File("prueba.doc"));
                    //esto abre un documento en blanco

                    addFileMenu(frame);
                } catch (SWTError e) {
                    System.out.println("Unable to open activeX control");
                    display.dispose();
                    return;
                }
                //fin abrimos un word
                //abrimos un navegador

                shell.open();

            }
        });

        //el titulo
//      shell.setText("Word Example");

        while (!shell.isDisposed()) {
            if (!display.readAndDispatch())
                display.sleep();
        }
        display.dispose();
    }

    static void addFileMenu(OleFrame frame) {
        final Shell shell = frame.getShell();
        Menu menuBar = shell.getMenuBar();
        if (menuBar == null) {

            shell.setMenuBar(menuBar);
        }
        MenuItem fileMenu = new MenuItem(menuBar, SWT.CASCADE);
        fileMenu.setText("&File");
        Menu menuFile = new Menu(fileMenu);
        fileMenu.setMenu(menuFile);
        frame.setFileMenus(new MenuItem[] { fileMenu });

        MenuItem menuFileOpen = new MenuItem(menuFile, SWT.CASCADE);
        menuFileOpen.setText("Open...");
        menuFileOpen.addSelectionListener(new SelectionAdapter() {
