Following code snippet shows how to create a zip archieve from multiple files.

import java.util.Iterator;

import java.util.ArrayList;
import java.io.*;

public class ZipDemo {
    static int BUFFER_SIZE = 1024;
    static String zipArchieveName = "allfiles.zip";

    public static void main(String args[]) {
        try {
            // Reference to the file we will be adding to the zipfile
            BufferedInputStream origin = null;

            // Reference to zip file
            FileOutputStream dest = new FileOutputStream(zipArchieveName);

            // Wrap our destination zipfile with a ZipOutputStream
            ZipOutputStream out = new ZipOutputStream(new BufferedOutputStream(dest));

            // Create a byte[] buffer that we will read data from the source
            // files into and then transfer it to the zip file
            byte[] data = new byte[BUFFER_SIZE];

            List files = new ArrayList();
            files.add("/tmp/systemInfo.txt");
            files.add("/tmp/osgiInfo.txt");
            files.add("/tmp/errorInfo.txt");

            // Iterate over all of the files in list
            for (Iterator i = files.iterator(); i.hasNext();) {
                // Get a BufferedInputStream that we can use to read the source file
                String filename = (String) i.next();
                System.out.println("Adding: " + filename);
                FileInputStream fi = new FileInputStream(filename);
                origin = new BufferedInputStream(fi, BUFFER_SIZE);

                // Setup the entry in the zip file
                ZipEntry entry = new ZipEntry(filename);
                out.putNextEntry(entry);

                // Read data from the source file and write it out to the zip file
                int count;
                while ((count = origin.read(data, 0, BUFFER_SIZE)) != -1) {
                    out.write(data, 0, count);
                }

                // Close the source file
                origin.close();
            }

            // Close the zip file
            out.close();
        }
        catch (Exception e) {
            e.printStackTrace();
        }
    }
