如何在Java Form中嵌入Microsoft Word？

Question

I want to read a word document with the help of microsoft word but that would be limited to my java form . The document will be opened in java form with the help of microsoft word .

Like the following picture , I want to develop something :

User can edit the doc according to their need . But when they want to save the document , the document will be saved in a remote machine .

I can open the word document with the help of microsoft word by the following code :

try {
            /* if (Desktop.isDesktopSupported()) {
                  Desktop.getDesktop().open(new File("E:\\finger.docx"));
             }*/
            Process p = Runtime.getRuntime()
                .exec("rundll32 url.dll,FileProtocolHandler E:\\finger.docx");
             p.waitFor(); 
            System.out.println("Done.");
        } catch (IOException ioe) {
              ioe.printStackTrace();
        }
        catch (InterruptedException ex) {
                Logger.getLogger(JavaFromWord.class.getName()).log(Level.SEVERE, null, ex);
            }

But I do not know how can I embed the word viewer in JForm . Please help me .

Answer 1

As others have pointed out, this sounds a lot like an XY problem—meaning, you have already decided that the best solution is using Microsoft Word, so you are asking how to embed Microsoft Word instead of asking about your actual goal, which appears to be incorporating formatted text in a user interface.

A good way to do this is with a JEditorPane containing HTML content:

import java.awt.EventQueue;
import javax.swing.JEditorPane;
import javax.swing.JFrame;
import javax.swing.JScrollPane;

public class HtmlPane {
    static void show() {
        JEditorPane content = new JEditorPane("text/html",
            "<p>" +
            "The process of finger enrollment is now to be done in database." +
            " Previously it was done in file template." +
            " There are several reasons behind this:" +
            "<ol>" +
            "<li>" +
            "Time:<br>" +
            "--------" +
            "<p>" +
            "The process of verification in file template based method takes" +
            " 6.9 s on average.  On the other hand, in database based method," +
            " it takes only 3.5 s." +
            "<p>" +
            "The code for determining time is as follows:" +
            "<blockquote>" +
            "<pre>" +
            "Dim StartTime, Elapsed Time\n" +
            "StartTime = Timer\n" +
            "ElapsedTime = Timer.CheckTime\n" +
            "</pre>" +
            "</blockquote>" +
            "</ol>");

        content.setEditable(false);

        JFrame frame = new JFrame("finger");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.getContentPane().add(new JScrollPane(content));

        frame.pack();
        frame.setLocationByPlatform(true);
        frame.setVisible(true);
    }

    public static void main(String[] args) {
        EventQueue.invokeLater(() -> show());
    }
}

(Note: The Swing HTML renderer only supports HTML 3.2.)

If you aren't familiar with HTML, I advise you to learn it. Basic HTML is very easy to write. Plus, you need to know basic HTML to be an effective Java programmer, because professional development requires writing javadoc, and all javadoc is in HTML.

实际上，您不能在Java gui应用程序中显示任何非您的项目框架，这实际上是不真实的-您只能在JInternalFrame中显示Java框架
