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. Update the com. ibm. example. Per son class to support serialization and XML serialization by adding JAXB annotations.
• B. 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.
• 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 the "Global" check box is selected on the Wire Configuration page.
