Help.  no matter what I do.  I'm trying to move the firstname.lastname@xxx.ccc.nnn
actually the "firstname.lastname" eventually to a field called str_akouser.
public static void InsertLetter_A_Cand_Email_t(String emailAddress,String strBdId,String strSsn)
      {    String a = null;
            a = emailAddress;
            int la_return = 0;      
            Statement stmt = null;
            Connection con = null;
            ResultSet rs = null;
            String sysDate = null;
            String str_akouser = null;
      
          String[] sa_email = split(emailAddress, "@");
          
      //I get the out of bounds exception here      
                           
            str_akouser = sa_email[0];


private static String[] split(String theStr, String delim) {
                  
            StringTokenizer st = new StringTokenizer(theStr, delim);
            int count = st.countTokens();
            int index = 0;
            String[] arr = new String[count];
            if (count > 0) {
                  while (st.hasMoreTokens()) {
                        arr[index] = st.nextToken();
                        index++;
                  }
            }
            return arr;
      }

Make sure to check that emailAddress is not null.  Also, you may want to know whether it had any "@" in it in the first place, or more than one.  Check the .length of sa_email after it comes back from your split() function.

Cheers.

I checked the Sun website and it said that you should avoid using the StringTokenizer class because it's use has been replaced by newer and better classes... they recommended the following method to achieve the same result you are after... try this code instead of what you have for the split() method:

private static String[] split(String theStr, String delim){
   String[] arr = null;

   if (delim != null && theStr != null) {
      // the following is built-in to the String class
      arr = theStr.split(delim);
   }

   return arr;
}

I forgot to include the link to the article I found on the Sun website...
