NO.2 Sunil is developing a database access portlet. He wants to query the database in the processAction()
method and pass complex data transfer object to render() method for rendering. What mechanism would
you suggest to Sunil for transferring custom java object from action to render phase?
A.Only way to pass data from Action to render phase is using PortletSession object
B.You cannot pass custom object created in processAction() method to render() method. If you do so it
will result in ClassCastException when you try to access that object in render() method.
C.The default value of javax.portlet.actionScopedRequestAttributes container runtime option is true. So
you can set custom java object as request attribute on ActionRequest and it will be available as request
attribute in RenderRequest.
D.Change portlet.xml to set the javax.portlet.actionScopedRequestAttributes container runtime option to
true. Once actionScopedRequestAttributes is set to true you can set custom java object as request
attribute on ActionRequest and it will be available as request attribute in RenderRequest..

NO.6 Sunil is developing a simple 1 page standard portlet. Only thing that this portlet does is forward control
to different JSP based on the browser, locale,Sunil is developing a simple 1 page standard portlet. Only
thing that this portlet does is forward control to different JSP? based on the browser, locale, markup of the
request. How can Sunil implement this functionality?
A.Use Client Profile information (CC/PP) API to find out the browser related information and develop your
logic that forwards control to different JSPs based on client information
B.Use dispatch() method of Client Profile information API instead of
PortletContext.getRequestDispatcher() method and profile information API will take care of forwarding to
different JSPs based on client information
C.He will have to create hidden inputs in the form and use javascript to submit browser information to the
server side. Then on the server side develop custom logic based on the submitted information for
forwarding control to different JSPs based on the browser.

only thing that Sunil needs to do is create standard directory structure defined by WPS and create JSP
files under appropriate directory structure. When you call PortletContext.getRequestDispatcher(), Portal
server will make sure that it picks up correct JSP based on the client information.
