Programming Jakarta Struts

Using URL Parameters

URL parameters are strings that are sent to the server with the client request. The parameters are inserted into the HttpServletRequest object from the URI query string and data that is sent in a POST method. The parameters are formatted as key/value pairs and are accessed by applications as request parameters. URL parameters play an important role in all web applications, and the Struts framework is no exception.

Tip

Don’t get request parameters confused with request attributes. Attributes are objects that typically are inserted into the request so that they can be made available to other servlets, such as JSP pages.
