Hi,

        The data I received is via an HTTPS Post.  And I store the value of
the compress data into a string. But if Java handles strings and char
differently, what is the best way. Coz I tried using byte[] to store the
data and it is not successful.

Please take note before compressing, I have to decode the data which is
encode in Base64.

        I used the sun.misc.Base64Decoder to decode.

        FYI. If i don't used any encoding, the following function work but
if I used an ecoding it does work.

         Could some please suggest me an answer.
Cheers,
S.Thanika


sun.misc.BASE64Decoder dec = new sun.misc.BASE64Decoder();
byte[] strinf = dec.decodeBuffer(encstr);
String str = xx.inflate(strinf);

public  String decompress(byte[] inStr){
      byte[] b2 = new byte[inStr.length];
      b2 = inStr;
      Inflater decompresser = new Inflater();
      decompresser.setInput(b2,0,b2.length);
      int xxxxx =0;
      try {
        xxxxx = decompresser.inflate(b2);
      }
      catch (Exception e) {
        System.out.println("decompress exception ...");
        e.printStackTrace();
      }
      System.out.println("decompress ... " + inStr.length() + " out: " +
xxxxx);
      decompresser.reset();
      decompresser.end();
      String outStr = new String(b2,0,xxxxx);
      outStr.trim();
      return outStr;
    }
