adding a file to a zip file

Posted on 2007-11-29
Last Modified: 2010-03-30
Here is basically my what my code is doing

Creates a XML file
Creates a zip file (XML file is not included)
FTPs the zip

What I need to do now is add the XML to the zip file.  I tried to do:
out.putNextEntry(new ZipEntry(XMLName));      

This put the file name in the zip file but with no data.  I am attaching my zip code
//***********************************************************Start ZIP       
        byte[] buf = new byte[1024];
	try {
	    // Create the ZIP file
	    String target = path;
	    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)));
	        //New Zip suff
                if (remember.elementAt(i).lastIndexOf('\\') != -1) {
                slash = remember.elementAt(i).lastIndexOf('\\');
                } else {
                slash = remember.elementAt(i).lastIndexOf('/');
                name = remember.elementAt(i).substring(slash + 1);
                out.putNextEntry(new ZipEntry(name));	
                // Transfer bytes from the file to the ZIP file
		int len;
		while ((len = in.read(buf)) > 0) {
		    out.write(buf, 0, len);
		// Complete the entry
	    // Complete the ZIP file
	} catch (IOException e) {
	System.out.println("Zip File is Completed"); 
//*****************************************************End ZIP

some thing like
FileInputStream in = new FileInputStream(filenames[i]);
            // Add ZIP entry to output stream.
            out.putNextEntry(new ZipEntry(filenames[i]));
            // Transfer bytes from the file to the ZIP file
            int len;
            while ((len = in.read(buf)) > 0) {
                out.write(buf, 0, len);
            // Complete the entry
