[SOLVED] How is that servlet-name and servlet-class differs?

How is that servlet-name and servlet-class differs?

I followed a servlet tutorial, created a servlet(HelloServlet) in a java file named HelloServlet.java.Compiled the .java file to HelloServet.class. My questions 1) Is the servlet's name is same with servlet file(name for the compiled java file) or should be different?

This is because on the example I followed, he set the servlet-name different from the servlet-class, in web.xml.

Solution

servlet-name is not related to servlet class name. it is used to link the servlet class with the servlet mapping. In the below example i have used servlet-name XXX while declaring a servlet and then mapped it with the test url by giving the same servlet-name in the mapping file.

<servlet>
<servlet-name>XXX</servlet-name>
<servlet-class>className</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>XXX</servlet-name>
<url-pattern>/test</url-pattern>
</servlet-mapping>
