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

news-oriented community sites like Slashdot, and personal weblogs. But it's not just for news.

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.

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.

Correct Answer: B

nteroperability between JSR 286 portlet events and JSR 168 cooperative portlets By concept, cooperative portlets are similar to JSR 286 portlet events. Both concepts describe publish/subscribe communication patterns that are based on typed information that is published and received by portlets and propagated via communication links.

Because the concepts are quite similar, the portal supports data exchange between JSR 168 cooperative portlets and JSR 286 portlets that support events. This means that you can extend an existing setup using JSR 168 cooperative portlets with new JSR 286 portlets and that you can smoothly migrate individual cooperative portlets to the new API without losing communication possibilities.

Correct Answer: A

: PumaProfile Contains methods that provide read-only access to the User and Group attributes and identifiers. You can use this interface to get the User object for the current user. PumaLocator Contains methods for looking up User and Group objects. You can use this interface to obtain a List of Group objects for all of the groups in which the current user is a member. Beginning with Version 7.0 of WebSphere?Portal, paging is supported. Which means that the result set is split up into subsets (pages) and a special iterator can be used to access the pages. PumaController Contains methods for creating and deleting Users and Groups and for modifying the User and Group profiles and membership. PumaEnvironment Contains methods to retrieve virtual principals, access general properties for user management, and a method to bypass access control for the user and group management layer. Before the portlet can use these provider objects, it must first retrieve the appropriate home interface, depending on the type of application. Standard portlet com.ibm.portal.um.portletservice.PumaHome

The Controller SPI provides controllers for portal resources. You can use these controllers to modify portal resources that are exposed by particular models of the Model SPI. Controllers offer methods to modify the topology and properties of the model and of its nodes. They expose the same interfaces as the corresponding read-only model, and they instantly reflect modifications that you apply to the controller. Note: While the modifications come into effect immediately for the controller, they not reflected in the persistence layer until you commit the controller and the changes that you made by it.
