unable to store encrypted characters through servlet

Arod,

Here goes:


To encode:
////////////////////////////////////////////////

// Convert the byte array into one big string
byte[] bytes = // YOUR DATA IN A BYTE ARRAY
Object send = null;
String asciiTemp = null;
int asciiTempLength = 0;
StringBuffer hexEncoded = new StringBuffer();
try {
     for( int byteCounter = 0; byteCounter < bytes.length; byteCounter++ ) {
          asciiTemp = Integer.toHexString((int)bytes[byteCounter]);
          asciiTempLength = asciiTemp.length();
          if( asciiTempLength > 2 ) {
               asciiTemp = asciiTemp.substring(asciiTemp.length()-2);
          }
          else if( asciiTempLength == 1 ) {
               asciiTemp = "0"+asciiTemp;
          }
          hexEncoded.append(asciiTemp+":");
     }
}
catch( Exception e ) {
     e.printStackTrace();
}
contentType = "text/plain";
send = hexEncoded.toString();

////////////////////////////////////////////////

To transmit from the servlet:

////////////////////////////////////////////////

// Write a text stream
System.out.println("Writing output");
OutputStream outStream = response.getOutputStream();
PrintWriter out = new PrintWriter(outStream);
out.write((String)send);
out.flush();
outStream.flush();
out.close();
outStream.close();

////////////////////////////////////////////////

To decode back into a byte array

////////////////////////////////////////////////

URL request = new URL("http...YOUR URL");
URLConnection connection = request.openConnection();

// Get the response
connection.setDoInput(true);
InputStream inStream = connection.getInputStream();
InputStreamReader inr = new InputStreamReader(inStream);
BufferedReader br = new BufferedReader(inr);
int size = 0;
String data = br.readLine();
br.close();
inr.close();
inStream.close();

// Reconstruct the byte array from the string
StringTokenizer byteTokenizer = new StringTokenizer(data, ":");
bytes = new byte[byteTokenizer.countTokens()];
int byteCount = 0;
while( byteTokenizer.hasMoreTokens() ) {
     //bytes[byteCount] = Byte.parseByte(byteTokenizer.nextToken());
     bytes[byteCount] = (byte)Integer.parseInt(byteTokenizer.nextToken(), 16);
     byteCount++;
}
System.out.println("Data retrieved: "+byteCount+" bytes");
System.out.println("Request = "+newURL);
URL request = new URL(newURL);
URLConnection connection = request.openConnection();
