MVC Portlet

A traditional JSP-based portlet using Liferay’s MVC framework.

• Simple portlets with server-side rendering (no React/Angular).
• Legacy support (still widely used).

Implementation

Create the Portlet

blade create -t mvc-portlet todo-list-portlet

Add a JSP View

<!-- todo-list-portlet/src/main/resources/META-INF/resources/view.jsp -->
<%@ taglib uri="http://java.sun.com/portlet_2_0" prefix="portlet" %>

<portlet:defineObjects />

<h1>My To-Do List</h1>
<ul>
  <li>Learn Liferay</li>
  <li>Build a portlet</li>
</ul>

Add Portlet Configuration

todo-list-portlet/src/main/java/.../TodoListPortlet.java

@Component(
    property = {
        "javax.portlet.display-name=Todo List",
        "javax.portlet.name=" + TodoListPortletKeys.TODOLIST
    },
    service = Portlet.class
)
public class TodoListPortlet extends MVCPortlet {
    // Optional: Add controller logic here
}

Use Cases

• Simple UIs: FAQ sections, contact forms.
• Legacy Integrations: Portlets needing JSP/Struts.
