Chapter 2 ?– Controlling Web Application Behavior with web.xml 44
Defining Custom URLs
To assign a custom URL, you use the servlet-mapping element along with its
servlet-name and url-pattern subelements. The servlet-name element
specifies the name that was assigned to the servlet using the servlet-name subelement
of the servlet element; url-pattern describes a URL relative to the Web
application root. The value of the url-pattern element must begin with either a
slash (/) or an asterisk and period combination (*.).
Core Approach
The value of url-pattern must begin with either / or *..
The specification allows you to map a servlet to a particular custom URL. For example,
here is a simple web.xml excerpt that lets you use the URL http://host/webApp-
Prefix/UrlTest1 to invoke TestServlet1 declared with the name Test1. Figure
2??“1 shows the result of invoking TestServlet1 with the exact-matching URL.
