Doubt in getting from jsp in to Action

[Naveen Mishra]

Hi.
just a simple doubt regarding getting parameter/attribute in action from jsp...


I'm using following line and getting data properly in my action class --
categoryName =request.getParameter("catName");

but not getting into action when using following line --
categoryName =request.getAttribute("catName");

Any logic/ reason or THUMB-RULE when to use getAttribute(...) and when getParameter(...)


Thanks .

Parameters are String values that are submitted (either on the URL or encoded in the post data). Attributes are objects of any type that your code, or the Struts framework, can attach to the request. You cannot add, edit or remove Parameters, but you can do this with Attributes.
