<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Welcome</title></head>
<body>
<p>Hello World</p>

</html>

Step 5: Run dynamic web project using tomcat server

So index.jsp is present in welcome file list of web.xml file then whenever server starts it loads welcome file i.e index.jsp
We can give any name t our jsp but it should present in web.xml as welcome file
<welcome-file>index.htm</welcome-file> . no need of other files which names are created by default we can delete those things.
Right click on the project and => run as => run on server=> select tomcat version = >add our project if not added click on finish.
