Hi

I am trying to use struts 2 token session interceptor

Bellow is part of my struts.xml



I have 2 jsp clientForm.jsp which has 3 input field. on submit of clientForm.jsp data goes into database and control go to client.jsp

which display all the records from the table.

Things were working fine before i configured token-session but when user refreshes the browser page duplicate records were gettin inserted so i thought of using token-session interceptor.

But after configuring token-session interceptor i am not able to insert record in database.

bellow is the warning which i am getting on Console



I have added the bellow tags in my clientForm.jsp and client.jsp



Am i using token-session at right place ?

What's the reason of the warning which i am getting.

Looking at the generated HTML will answer your first question as to why the <s:token/> tag must be inside the form. Plus the docs state:
Note: To set a token in your form, you should use the token tag. This tag is required and must be used in the forms that submit to actions protected by this interceptor.

Note the "in the forms" part.

You're using the "token-session" interceptor; if you're only trying to protect a single form try using the "token" interceptor.
