Hello,

* Opens the documentation in an JavaHelpViewer.
protected void showDocumentation() {
     String jarFilePath = ".../test.jar";
     HelpSet hs = getHelpSet(jarFilePath);
     if (hs!= null) {
     HelpBroker hb = new HelpBroker(hs);
hb.setDisplayed(true);
     else {
     System.out.error("Can't find the helpSet-file.");
* Returns the HelpSet file which is in included into the given
* jar file.
* @param jarFilePath
* @return the HelpSet file, or null, if the HelpSet file is not found.
protected HelpSet getHelpSet(String jarFilePath) {
     HelpSet hs = null;
     try {
     String hsName = null;
     JarFile jar = new JarFile(jarFilePath);
     Enumeration entries = jar.entries();
     while (entries.hasMoreElements()) {
          ZipEntry entry = (ZipEntry) entries.nextElement();
          String entryName = entry.getName();
          if (entryName.endsWith(".hs")) {
          hsName = entryName;
          break;
     URL url[] = getURLs("file:" + jarFilePath);
     ClassLoader cl = new URLClassLoader(url);
     URL hsUrl = HelpSet.findHelpSet(cl, hsName);
     hs = new HelpSet(cl, hsUrl);
     catch (Exception exc) {
     System.out.error("Can't find a HelpSet file in: " +jarFilePath");
     hs = null;
     return hs;
