JSP Actions are special tags that allow you to perform specific tasks in a JSP page. These tags can be used to include other resources, forward to other pages, set property values, and create JavaBeans. By using Java Server Pages (JSP) Actions, you can make your JSP pages more dynamic and interactive.

JSP Action Types
The forward action forwards the current request to another resource, which can be a JSP page, a servlet, or a static resource. The syntax for the forward action is:
<jsp:forward page="nextpage.jsp" />
The include action includes the content of another resource in the current JSP page. The included resource can be a JSP page, a servlet, or a static resource. The syntax for the include action is:
<jsp:include page="includedpage.jsp" />
The param action sets a request parameter that can be accessed by the included resource. The syntax for the param action is:
<jsp:include page="includedpage.jsp"> <jsp:param name="paramName" value="paramValue" /> </jsp:include>
The setProperty action sets a property of a JavaBean that can be accessed by the included resource. The syntax for the setProperty action is:
<jsp:useBean id="myBean" class="com.example.MyBean" scope="request" /> <jsp:setProperty name="myBean" property="myProperty" value="myValue" />
The useBean action creates a JavaBean that can be accessed by the included resource. The syntax for the useBean action is:
<jsp:useBean id="user" class="com.example.User" scope="session" />
JSP actions provide a powerful and flexible way to create dynamic and interactive web applications. By using these actions, developers can easily create reusable components and improve code organization. By understanding the different types of actions and their syntax, developers can leverage the full power of JSP to build high-quality web applications.
