• Question 33:

  Which statement is true regarding JSR 286 event support in IBM WebSphere Portal?

  A. Events can be wired to IBM API cooperative portlets.

  B. Events can be wired to JSR 168 cooperative portlets.

  C. Events cannot be used in tandem with public render parameters.

  D. When the "Global" check box is set on the wires page. JSR 286 event processing is automatic; wires are not needed and. therefore, are ignored.

  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.

  Portletl

  Porrtlet2

  PortletFiltec

  mycompany,MyPortletFilter

  ACTION_PHASE

  PortletFilter

  Portletl

  Poctlet2

  Assuming that the mycompany.MyPortletFilter class implements the right interfaces, which statement is true?

  A. The portlet filter will be applied to both portlets and can be used during the action phase.

  B. The portlet filter will be applied to first portlet to render, and can be used during the action phase.

  C. The portlet filter will be applied to both portlets, but the section should go in the web.xml instead.

  D. The portlet filter will be applied to the first portlet to render, but the section should go in the web.xml instead.

  Correct Answer: A

• Question 38:

  Jack wants to allow users to bookmark his portal page. He is using the following code:

  My Page

  What change must he make to this code to allow users to bookmark the page?

  A. The code is correct and will allow the users to bookmark the page.

  B. He must include the normalize="true" attribute to indicate that the URL to be generated should be normalized.

  C. He must include the forceAbsolute="true" attribute to indicate that the URL to be generated should be absolute.

  D. He must include the keepNavigationalState="true" attribute to indicate that the URL to be generated should keep the current navigational state, which will include all portlet modes, states, and render parameters in the URL.

  Correct Answer: D

• Question 39:

  Which statement is true regarding the processAction lifecycle method?

  A. It generates the HTML page for the portal.

  B. It generates the HTML fragment for the portlet

  C. It can publish an event by calling the setEvent method.

  D. It can handle an event that is published by another portlet.

  Correct Answer: B

  Portlets should not use tags that impact content generated by other portlets or that may even break the entire portal page.

  Inclusion of such a tag invalidates the whole markup fragment. Portlets generating HTML fragments must not use the following tags: base, body, iframe, frame, frameset, head, html, or title.

  Portlets generating XHTML and XHTML-Basic fragments must not use the following tags:

  base, body, iframe, head, html, or title.

• Question 40:

  Arthur developed two portlet applications to support the same event-- the choosePerson event. This event uses the "http://example.ibm.com/portlets" namespace, and its payload type is the com.ibm.example .Person class.

  Arthur deployed one portlet from each portlet application to the same portal page. He also wired one portlet (Portlet A) as the event source and the other portlet (Portlet B) as the event target. When Arthur tests the portlet communication, he

  does not see that the com. ibm. example. Person object was transferred to Portlet B after the event was fired from Portlet A.

  How can Arthur resolve this problem for optimal performance?

  A. Ensure that the "Global" check box is selected on the Wire Configuration page.

  B. Update the com. ibm. example. Per son class to support serialization and XML serialization by adding JAXB annotations.

  C. Move the com. ibm. example. Person class out of the two web archive (WAR) files and into an IBM WebSphere Application Server shared library that is used by both WAR files.

  D. Ensure that "http://example.ibm.com/portlets" namespace is specified as the direct namespace for the event declaration for both portlet.xml files, rather than the default namespace for each portlet.xml file.

  Correct Answer: D
