stfinal ="Helloadasdasdasd";

ByteArrayOutputStream bout = new ByteArrayOutputStream();
 ZipOutputStream zout=new ZipOutputStream(bout);
 zout.putNextEntry(new ZipEntry("file.html"));

InputStreamReader input = new InputStreamReader(new StringBufferInputStream (stfinal));

 int numRead=0;
 int size=0;

while (numRead != -1) {
   numRead = input.read(b,size,1000);
   size+=numRead;
   }

zout.closeEntry();
 zout.finish();
 out.flush();
 String zip=bout.toString();
 res.setContentType("application/zip");
 res.setHeader("Content-Disposition","inline; filename=output.zip;")

out.println(zip);
