Creating a XML file in java

Posted on 2007-11-26

I have a program that allows the user to drag and drop files in to a window.  I then click a button and the program zips the files that have been dragged.  Is it possible that when the zip file button is clicked the program can create a xml file.  The file would look something like this

file 1
file 2                 ,<----- then the names of all the files in the window

I will attach the code that zips
import java.awt.*;

import java.awt.event.*;

import javax.swing.*;

import java.util.Vector;



class UploadDriver implements ActionListener {

    final Vector<String> remember = new Vector<String>(); 


    public UploadDriver () {

        javax.swing.JFrame frame = new javax.swing.JFrame( "FileDrop" );

	javax.swing.JButton doit = new javax.swing.JButton("Upload Files!"); 


	//javax.swing.border.TitledBorder dragBorder = new javax.swing.border.TitledBorder( "Drop 'em" );

        final javax.swing.JTextArea text = new javax.swing.JTextArea();


				   new javax.swing.JScrollPane( text ), 

				   java.awt.BorderLayout.CENTER );

        frame.getContentPane().add(doit, java.awt.BorderLayout.SOUTH); 


        new FileDrop( System.out, text, /*dragBorder,*/ new FileDrop.Listener()

        {   public void filesDropped([] files )

            {   for( int i = 0; i < files.length; i++ )

                {   try


			text.append( files[i].getCanonicalPath() + "\n" );


		    }   // end try

                    catch( e ) {}

                }   // end for: through each dropped file

            }   // end filesDropped

        }); // end FileDrop.Listener

        frame.setBounds( 100, 100, 300, 400 );

        frame.setDefaultCloseOperation( frame.EXIT_ON_CLOSE );;



    public void actionPerformed(ActionEvent ae) {

	System.out.println("Time to zip it, zip it good"); 

	System.out.println("Looking to zip " + remember.size() + " files"); 

	byte[] buf = new byte[1024];


	try {

	    // Create the ZIP file

	    String target = "";

	    ZipOutputStream out = new ZipOutputStream(new FileOutputStream(target));


	    // Compress the files

	    for (int i=0; i<remember.size(); i++) {

		FileInputStream in = new FileInputStream(remember.elementAt(i));


		// Add ZIP entry to output stream.

		out.putNextEntry(new ZipEntry(remember.elementAt(i)));


		// Transfer bytes from the file to the ZIP file

		int len;

		while ((len = > 0) {

		    out.write(buf, 0, len);



		// Complete the entry





	    // Complete the ZIP file


	} catch (IOException e) {


	System.out.println("You have been ZIPPED");

Sure.  Make a new .xml file outside the loop where you manipulate the list of files.  Write the 2 header lines to the top, then for each file, write the file name to the .xml file.

If you plan to use XML syntax, then surround the data with XML tags, e.g.

I know this is some what of a second question, but I will create a new question if you experts think I should.

But if you look at the above code, where it is zipping the files it is putting in complete paths to the files



So when it unzips the full path is still part of the file.  Is it possible to only zip the file? and not the complete path


That way when I move the zip, it is not dependent on the dir structure

Use the file's name -- the last element in the absolute path -- as the new ZipEntry.

And yes, it's a very different question.  But if we don't have to spend much time on it, then we'll just include it here.
