String to MD5 hex

Question

hi all, i need a way to convert a String to an MD5, to be more precise i need to get the MD5 string in hex. I have tried a few methods but they only seem to work 80% of the time, any help would be appriciated.
note: i am storing values in a mysql db (just a test will try SHA later) when i put the data in the my sql i pass it as a string using MD5("myString")
thanks

Well i got it and it works perfectly in case any wants to now this is the code
import java.security.MessageDigest;
public class MD5Maker
     public static String makeMD5(String str){
          String MD5HexString = null;
          try{
             byte[] intext = str.getBytes();
             StringBuffer buf = new StringBuffer();
             MessageDigest md5 = MessageDigest.getInstance("MD5");
             byte[] md5bytes = md5.digest(intext);
             for( int i = 0 ; i < md5bytes.length ; i++ ) {
                   int value = 0xff & ((int)md5bytes);
               if (value < 16)
                    buf.append("0");
               buf.append(Integer.toHexString(value));
               MD5HexString = buf.toString();
          catch (Exception e) {}
          return MD5HexString;
