Re: Tokens

The Struts saveToken() & isTokenValid() methods save a token so that 
double submits are detected and can be dealt with.  Just disabling the 
submit button won't stop a user submitting and then refreshing the page 
(which submits the same info twice) or going back in their history and 
clicking submit on an earlier page.

Don't mean to jump in if you already have found a good solution, but wouldn't it be simpler to just not allow the user to press the submit btton twice?  It is easy (using Javascript) to disable a submit button once it has already been pressed..

Call saveToken() in GET (or read)
Test isTokenValid() in the POST (or write) to see if it is a dupe (duplicate
returns false [bad token])
worse is better

hi  Ramadoss

Thanks for your help. But this is not i m looking for.
I may not be able to explain my question proeprly .
But i m looking for saveTOken() method implementation in struts which does
not allow duplicate entry of records into the database when the user click
on submit button twice.

Hi Gurpreet,
       If what I understand is correct from your question, you can
use
     

split function the same way as you use String Token...following is sample
snap shot
   

 String str = "botherouioero:and:foroffo:mar:ssod:slave";
       String[] arr = str.split(":", 9);
       System.out.println("length of arr[] is:" + arr.length);
       for (int i = 0; i < arr.length; i++) {
           System.out.println("value is :" + arr[i]);
       }
       String[] ar = str.split("o", 8);
       System.out.println("length of arr[] is:" + ar.length);
       for (int i = 0; i < ar.length; i++) {
           System.out.println("value is :" + ar[i]);
       }
Where the number 9 and 8 denotes number of occurences you want to
consider
     

after which it will be treated as whole single string and will be included
into your String Array.
   

Hope this help,

-Ram
