Create a Dynamic Web Project in Eclipse. Let's say the name of the project is demo.
In the left panel of Eclipse, at the name of your project (demo in this example) > Java Resources > src, create a new package. For the sake of this tutorial, let's name the package com.demo.
In the package, create a class called myClass.java.
In return.java, add the following markup.
package com.demo;
public class myClass {
public String myMethod() throws Exception {
return "Hello World";
}
}
In the left panel of Eclipse, right click on the name of your project (demo in this example) and select New > JSP File. Select the WebContent folder, give the file a name such as index.jsp, and select Finish.
Add the following to line 1 of the JSP file. This is the combination of the package (com.demo) and the class (myClass.java).
<%@page import="com.demo.myClass"%>
Add the following inside the <body> tags.
- In this example, "myClass" must be used because the name of the class in myClass.java is myClass.
- In this example, "myMethod" must be cause because the name of the method in myClass.java is myMethod.
<body>
<%
myClass foo = new myClass();
out.println(foo.myMethod());
%>
</body>
Select the green play button in Eclipse, and hopefully something like this is returned.
