set parameter values interceptors before rendering JSP

[Prash Negu]

Hi,

We are using struts 2. I want to set some hidden parameter values in all JSP's. I am trying to achieve this using interceptors. The moment I call invocation.invoke();, the result is already generated. How do I set certain parameter values in interceptors?

Thanks,
Prashant

How do I set certain parameter values in interceptors? Before action execution or after action execution. Please make it more clearly that will help us to help you better.

For example, in below interceptor method, i would like set some JSP parameters after invoke() is called but before JSP is rendered. Can we do that?

public String intercept(ActionInvocation invocation) throws Exception
{
 
String result = invocation.invoke();
 
 
return result;
}

We can set the hidden variables in jsp itself why you want to it here.

Those are common hidden variables in all JSP's. I would like to to do it from common place like interceptors. I don't want all developers to set values for these hidden variables in their action methods.

if these params are required over all the jsps and if these are user actions specific/dependent you can as well put the in the session an play with them anytime...
just a word of caution though: playing with session variables might be dangerous to the appln if not used carefully..
