Storing compilation and deployment of a servlet

1. Store the servlet file inside the "classes" folder of the context for predefined context (root) the classes folder required to be created inside the WEB-INF folder.
   
2. For the compilation of the servlet, files use servlet-api.jar in classpath option of javac command. This jar file contains the package used by the servlet files. This jar file can be found inside the installation folder of the tomcat/lib folder.
   
3. Deployment: This is a process to create an URL for the servlet. The user will use the URL to access the servlet. This can be done by providing a few tags in the web.xml file. The tags are as follows:
   
   In web.xml file present side to classes folder:
   
   <servlet>
   <servlet-name>name</servlet-name>
   <servlet-class>class</servlet-class>
   </servlet>
   
   <servlet-mapping>
   <servlet-name>name</servlet-name>
   <url-pattern>/ url-pattern </url-pattern>
   </servlet-mapping>

Program

How to run this program

First create a folder named Servlet in any drive (here e: drive). Inside that folder create a WEB-INF folder (all letters will be capped mandatory). Copy the web.xml file from the (E:\Program Files\Apache Software Foundation\Tomcat 6.0\conf) folder. Again inside the WEB-INF folder, create a folder named classes. In the classes folder, we will store the Servlet files by their class name; here httpserv.java. Copy the servlet-api.jar (E:\Program Files\Apache Software Foundation\Tomcat 6.0\lib) file in the classes folder.

Web.xml setting:
