Here is the code in Test.java
package abc;

Thanks for detailed instructions in the question. I setup the web app per those details and found two issues:
- It's
not WEB_INF but WEB-INF. Please check if the folder name is indeed WEB-INF. - Here is the
updated index.jspso that returned value is displayed on the web page. The code in the JSP file gets executed in tomcat server and any System.out.println line would get logged in server logs (i.e. TOMCAT_INSTALLATION_DIR/logs/catalina.out ). Similarly, the value returned from function call is not going to get displayed unless you use<%= variable %>.
<%@ page import="abc.*"%>
<!DOCTYPE html>
<html>
<head>
<title>Insert title here</title>
</head>
<body>
<%
Test cc=new Test();%>
<%= cc.f() %>
</body>
</html>
In case these changes don't work, could you please paste the screenshot of the whole folder structure of all files under the Tomcat installation directory ? I am asking this as everything else is correct and it worked for me.
