Example
Here's a simple example of a Struts 2 action:
public class MyAction extends ActionSupport {
public String execute() {
return SUCCESS;
}
}
To use this action, you need to define a corresponding JSP page that displays a message:
<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
<head>
<title>Struts 2 Example</title>
</head>
<body>
<s:property value="message" />
</body>
</html>
In this example, the s:property tag is used to display the value of the message property in the action class.
Conclusion
Struts 2 is a powerful and versatile framework for developing Java EE web applications. With its extensive features and easy-to-use tag library, it's a great choice for any developer looking to build robust and scalable web applications.
