10.4.2 Manage Portlet Applications
Manage Portlet Applications helps you to identify and manage existing installed
Web modules (WAR file). It also displays the concrete portlet application
corresponding to the selected Web module. Using this portlet, you can uninstall
the portlet application and modify dynamically configured parameters or portlet
application settings.
Select the Manage Portlet Applications portlet and you should see a window
open as shown in Figure 10-35 on page 552. Using the Manage Applications
portlet, you will be able to:
򐂰 Show Info
򐂰 Update
򐂰 Un-install
Web modules can contain one or more portlet applications, servlets JSP files and
other files and are defined in the Web descriptor file (web.xml).
With the portlet applications belonging to the selected module, you can:
򐂰 Activate/Deactivate
򐂰 Rename
򐂰 Copy
򐂰 Modify Parameters
򐂰 Show Info
򐂰 Delete
Portal applications can contain one or more portlets. They are created implicitly
when the WAR file is deployed and they are packaged as an enterprise
application (ear file). You will see the default Web modules in Figure 10-35 on
page 552. This is installed during the WebSphere Portal installation.
Note: You need to select the portlet application belonging to the selected Web
module in order to see the icons for Activate/Deactivate, Copy, Modify
Parameters, Show Info and Delete.
