  E. The policy is stored in the WAR file and promoted to the EAR file by the portal during deployment.

  Correct Answer: AD

  The display name is assigned by the EAR developer and stored in the file application.xml.

  The policy is stored in the EAR file.

  You can register EAR files only by using an XML script with predeployed mode. You can remove EAR files by using either the administration portlet or an XML script.

  The context root is assigned by the EAR developer and stored in the file application.xml. You must ensure that the context root that you specify when you register the portlet matches the one specified in the EAR application.xml. (refer to the

  sample XML file RegisterPreDeployedEAR.xml.

  The portlet application is already extracted and deployed into the application server as part of the EAR file.

  The portal server reads the available portal configuration information (portlet.xml, etc.) from the location where the contained WAR file was extracted to.

  RSS is a format for syndicating news and the content of news-like sites, including major news sites like Wired,

  Pretty much anything that can be broken down into discrete items can be syndicated via RSS:

  the "recent changes" page of a wiki, a changelog of CVS checkins, even the revision history of a book.

  Once information about each item is in RSS format, an RSS-aware program can check the feed for changes and react to the changes in an appropriate way.

• Question 50:

  Which method can be used only in an ActionResponse?

  A. encodeURL

  B. setProperty

  C. addProperty

  D. setPortletMode

  Correct Answer: A

  Corresponding to the requests, there are the PortletResponse, ActionResponse and RenderResponse interfaces.

  The encodeURL() method of PortletResponse is used to encode URLs used to access other resources within the application, such as servlets, images and static files. The container will add in any addition state information that is required.

  The ActionResponse response is used by processAction(). This method can send a redirect, change the portlet mode, change the window state, and set parameters which will be included in subsequent render requests.
