Struts 2 - passing request parameters to jsp from an Interceptor

Hi,

I have created a log-in Interceptor which checks for a request parameter. If this parameter exists, I then add 2 request parameters and forward to a jsp. The 2 request parameters I add are the same names as 2 input elements on the form of the jsp.

My struts.xml contains the following snippet:



My Login Interceptor contains the following snippet:



A snippet from my corresponding jsp containing the input elements:



For some reason the request parameters set in my interceptor are not resulting in the form elements being populated with the appropriate values.

I would appreciate advice as to what I need to do to ensure these request values are set into the jsp.

Thanks in advance.

Can you show us more code of your interceptor. What's parameters (I suppose your action implements parameter aware but still I want to confirm)...

I'm not sure what your use-case is, but I'm suspicious that this is the right way to do it.

Interceptors are designed for cross-cutting concerns; I'm not convinced this is one (particularly since the interceptor will fire if someone decides to put that param in the URL--but perhaps that's what you want).

What are you trying to accomplish?
 
I agree. Here's the link: http://aspose.com/file-tools
