HI
i have create a project having VSJLIB reference in it

when i have code it as follows

<pre> public void CreateZipFile(string sPath)
   {
     FileOutputStream stream1 = null;
     ZipOutputStream stream2 = null;
     if (System.IO.File.Exists(sPath))
     {
	FileInfo info2 = new FileInfo(sPath);
        stream1 = new FileOutputStream(sPath.Replace
                                      (info2.Extension, ".zip"));
	stream2 = new ZipOutputStream(stream1);
			this.ZipOneFile(stream1, stream2,  sPath);
     }
     else if (Directory.Exists(sPath))
     {
	stream1 = new FileOutputStream(sPath + ".zip");
	stream2 = new ZipOutputStream(stream1);
	DirectoryInfo info1 = new DirectoryInfo(sPath);
	this.ZipDirectory(stream1, stream2, info1, sPath);
     }
     stream2.close();
     stream1.close();
     stream2.flush();
     stream1.flush();
    }

    private void CopyStream(FileInputStream src, ZipOutputStream
                                                             dest)
    {
	InputStreamReader reader1 = new InputStreamReader(src);
	OutputStreamWriter writer1 = new OutputStreamWriter(dest);
	while (reader1.ready())
	{
	  writer1.write(reader1.read());
	}
	writer1.flush();
    }
		
    /*ZipDirectory Method zips the entire directory*/
    private void ZipDirectory(FileOutputStream fos, ZipOutputStream 
                             zos, DirectoryInfo di, string SRootDir)
    {
	FileInfo[] infoArray2 = di.GetFiles();
	foreach (FileInfo info2 in infoArray2)
	{
           ZipEntry entry1 = new ZipEntry
               (info2.FullName.Substring(SRootDir.LastIndexOf(@"\")));
	   entry1.setMethod(8);
	   zos.putNextEntry(entry1);
	   FileInputStream stream1 = new FileInputStream
                                       (info2.FullName);
       	   this.CopyStream(stream1, zos);
	   zos.closeEntry();
	   stream1.close();
	}
	DirectoryInfo[] infoArray1 = di.GetDirectories();
	foreach (DirectoryInfo info1 in infoArray1)
	{
	   this.ZipDirectory(fos, zos, info1, SRootDir);
	}
     }
</pre>
