MD5 implementation gives different hash values from java1.2 to java 1.3

Question

Hi,
I have MD5 implementation using Java api. When i run the program using Java 1.2, I get one version of hash value. When i run the same program using Java 1.3/1.4 I get a different version of hash value.
the hash value generated by java1.2 authecticates correctly with server but the one generated by 1.3/1.4 gives me authetication failure with the server.
I serious doubt some encoding issue with md5 implementation from java 1.2 to java 1.3/1.4. I would like to know what is the root cause for getting a different hash with java 1.3/1.4
Thanks

Here is the code, I am converting the string to bytes and then passing it to md.
public static String getMD(String strInput) {
/*---- Local Variable Declares ----*/
String rStr = new String();
try {
MessageDigest md = MessageDigest.getInstance("MD5");
md.update(strInput.getBytes("UTF-8"));
byte[] challengeResponse = md.digest();
System.out.println("Len of BYTE ary in JAVA:" + challengeResponse.length);
rStr = new String(challengeResponse);
} catch(Exception e) {
System.out.println("\n\nException while calling getMD\n\n");
e.printStackTrace();
} /* end of try catch block */
return rStr;
When I run the code using java 1.2, I got the following is octal dump output
"0000000 037677 135543 076565 063432 136210 040616 004766 177265"
When I run the code using java 1.3/1.4, I go the following octal dump outpu
"0000000 037477 037543 076565 063432 037477 040477 004477 037477"
