In portlet project, to navigate between pages, you should not use the URL property to link to a page. Instead, portlets use navigation via action handling. You use the Page Navigation editor to set up links to pages; that is, the navigation editor sets the action property.
Here is an example to hyperlink ans button to open a new page:
# From within the IDE, create a new portlet project. This action creates the project and one page, PortletPage1.jsp.
# Create a second portlet page, called PortletPage2.jsp, for the project.
# Drop a Hyperlink component onto the first portlet page, PortletPage1. (You can drop the Hyperlink on the page in the Design window or on the PortletPage1 node in the Outline window.) Change the Hyperlink's text property to Next Page.
# Drop a Button component (found in the Basic section of the Palette) onto the second portlet page, PortletPage2.
# Open the Page Navigation Editor. It displays the two pages (PortletPage1.jsp and PortletPage2.jsp) of the application.
# Click the PortletPage1.jsp icon in the Navigation window to expand it, and then drag a connector from hyperlink1 to PortletPage2.jsp. Change the name of the connector from case1 to Page2.
# Click the PortletPage2.jsp icon in the Navigation window to expand it, and then drag a connector from button1 to PortletPage1.jsp. Change the name of the connector from case1 to Page1.
# Run and deploy the portlet. The browser displays PortletPage1 and you should see the Next Page hyperlink. When you click the Next Page hyperlink, the Apache Pluto Portal server displays PortletPage2. Click the Page2 button to return to PortletPage1.
