First of all, let's consider an example requiring portlet development in Ext. Suppose we need to develop a simple portlet to display static content as shown in the following screenshot. It has the message JSP Portlet for Palm Tree and the Palm-Tree Publications logo. They both have the title Liferay Portal Enterprise Intranets
and the reference link http://liferay.cignex.com.
So how do you develop a portlet with the view shown in the screenshot above? A JSP portlet would be the best choice on top of Liferay portal. We can develop a JSP portlet with the above view in Ext of Liferay portal. First, we will define a JSP portlet; then we will change the title and category of the portlet.
Note
Java Server Pages(JSP) technology provides a simplified and fast way to create dynamic web content. JSP technology enables rapid development of web-based applications that are server- and platform-independent. Refer to http://java.sun.com/products/jsp.
