Step	Description
1	Create a project with a name TestWeb under a package com.tutorialspoint as explained in the Spring MVC - Hello World chapter.
2	Create a Java class HelloController under the com.tutorialspointpackage.
3	Create a view file hello.jsp under the jsp sub-folder.
4	Download JSTL library jstl.jar. Put it in your CLASSPATH.
5	The final step is to create the content of the source and configuration files and export the application as explained below.

HelloController.java

TestWeb-servlet.xml

views.xml

hello.jsp

Once you are done with creating source and configuration files, export your application. Right click on your application, use Export → WAR File option and save the HelloWeb.war file in Tomcat's webapps folder.

Now, start your Tomcat server and make sure you are able to access other webpages from the webapps folder using a standard browser. Try to access the URL − http://localhost:8080/HelloWeb/hello and if everything is fine with the Spring Web Application, we will see the following screen.
