i am developing a application in struts 1.3 in struts i have a requirement that when click on the submit button of the form then the button gets disabled so as the user cannot submit the form multiple times for that i am using this code

<input value="Save" class="btnbg" type="submit" name="method"
onclick="this.disabled=true;" />

in this code on click of the button it gets disabled now it is getting disabled but i am facing a peculiar problem that action in the action class is not executing i am using DispatchAction class for execution of my action it code works fine if i remove onclick="this.disabled=true; the action gets executed but i am getting exception

javax.servlet.ServletException: Request[/AddFloor] does not contain handler parameter named 'method'. This may be caused by whitespace in the label text.

I haven't read carefully your post this is only useful when you are using struts2 - use token session interceptor in you using http://struts.apache.org/2.1.6/docs/token-session-interceptor.html


ocjp 6 — Feeding a person with food is a great thing in this world. Feeding the same person by transferring the knowledge is far more better thing. The reason is the amount of satisfaction which we get through food is of only one minute or two. But the satisfaction which we can get through the knowledge is of life long.

use token for struts 1
check with isTokenValid() before submitting the form.
 
It is sorta covered in the JavaRanch Style Guide.
