Hi,
I need to stop:
1. multiple post to an action
2. refresh of a page
using Struts.
What i tried was using the Struts Token.
I have a common BaseAction class that extends Action class. All the other
action classes extend the BaseAction class.
In my BaseAction class I did the following:
1. public static boolean blnFirst = true;
2. In execute method:
if(blnFirst){
System.out.println("****BaseAction: FIRST Time");
saveToken(httpRequest);
this.blnFirst = false;
}
Saving the token adds an attribute:
org.apache.struts.Globals.TRANSACTION_TOKEN_KEY in the session
Now when I try to check the validity of the token by
isTokenValid(httpRequest), it is everytime resolving to NULL.
This piece of code:
httpRequest.getSession().getAttribute(Globals.TRANSACTION_TOKEN_KEY) returns
some value only the first time.All the other time it returns null.
Do I need to save the token every time? (Which I dont think so) OR just
once(which I'm doing) OR is there any other way?
I'm resetting the token every time using resetToken(httpRequest).
Please help me out.
