How do you run servlet in tomcat?

Java

You Run a Servlet by deploying it on the server, which in this case is tomcat. We need to deploy the servlet in the Web Applications context.

When we talk of a Web application's context, we are referring to that Web application's root directory or path within a particular server. A special directory exists within the application hierarchy named WEB-INF. This directory contains all things related to the application that aren't in the document root of the application. It is this WEB-INF directory that is the Web application's root directory, also referred to as the context. The most important file here is web.xml, the name of the WebApp deployment descriptor.

Let us take a look at the various contents (files & folders) that will be present inside this WEB-INF directory:

1. /WEB-INF/web.xml - This is the Deployment Descriptor file

2. /WEB-INF/classes/ - This is the directory where all your Java class files will be placed

3. /WEB-INF/lib/ - This is the folder where all your JAR files go.

my tomcat is installed in c:\dev\Java\Jakarta-tomcat-4.0.1. This is my TOMCAT_HOME. Remember that, this path that is referred by TOMCAT_HOME might vary from PC to PC depending on the installation preferences of the user.

To Deploy the Servlet, you need to place the .class file corresponding to your servlet in the /WEB-INF/classes/ folder
