Jsp Mapping in web.xml

JSP URL MAPPING FOR AJAX REQUESTS

First of all we need to understand that the web.xml file provides configuration and deployment information for the Web components that comprise a Web application.

Under Netbeans Web.xml is present in  WEB-INF

As we know the Jsp files are ultimately converted into servlet .so we can also map our Jsp.

Mapping specifies the web container of which java servlet/jsp file  should be invoked for a url given by client. 

For Example if clieant needs to acess register.jsp then the url for that file can be mapped as

<servlet>
          <servlet-name>signup.jsp</servlet-name>
          <jsp-file>/register.jsp</jsp-file>
    </servlet>
    <servlet-mapping>
          <servlet-name>signup.jsp</servlet-name>
          <url-pattern>/signup.xml</url-pattern>
    </servlet-mapping>

Now in order to acess register.jsp client has to use the url as signup.xml .. Then the file register.jsp will be executed . Which hides actual identity of the resource .

Thank you
