Structure of the Project

The Structure of the project created by the Gradle or maven tool is the same. Java code and the resources are separated. It is easy to code to manage.

Let’s take a look, you do not see some familiar files like portlet.xml, Liferay-portlet.xml và Liferay-display.xml. Where are they? Next, we will review the content of the TestPortlet class.

And also in that “src/main/resources” folder, Go to the “View. JSP” page edit the data that data will display in google chrome as we have shown in the below figure.
