Hi Srikanth,

JSR 168 (Portlet 1.0)

In JSR 168 only three variables are defined:

* RenderRequest renderRequest
* RenderResponse renderResponse
* PortletConfig portletConfig


JSR 268 (Portlet 2.0)

In JSR 286 following variables are defined:

* RenderRequest renderRequest and RenderResponse renderResponse (if the JSP is included from render method)
* ResourceRequest resourceRequest and ResourceResponse resourceResponse (if the JSP is included from serveResource method)
* ActionRequest actionRequest and ActionResponse actionResponse (if the JSP is included from processAction method)
* EventRequest eventRequest and EventResponse eventResponse (if the JSP is included from processEvent method)
* PortletConfig portletConfig
* PortletSession portletSession (returns an existing session or null if no session exists)
* Map<String, Object> portletSessionScope (provides access to the portletSession attributes)
* PortletPreferences portletPreferences (provides access to the portlet preferences)
* Map<String, String[]> portletPreferencesValues (provides access to the portlet preferences as a Map)

HTH,
Arun

On top of that if you include <liferay-theme:defineObjects /> it will put a whole bunch of context sensitive objects into our JSP page context. Below is the list for the same.

• ThemeDisplay themeDisplay
• Company company
• Account account
• User user
• User realUser
• Contact contact
• Layout layout
• List<Layout> layouts
• long plid
• LayoutTypePortlet layoutTypePortlet
• long scopeGroupId
• PermissionChecker permissionChecker
• Locale locale
• TimeZone timeZone
• Theme theme
• ColorScheme colorScheme
• PortletDisplay portletDisplay
• long portletGroupId

For more details on that refer below link.

These are the taglib's you need to import to use the above:

<%@ taglib uri="http://liferay.com/tld/portlet" prefix="liferay-portlet"%>
<%@ taglib uri="http://java.sun.com/portlet_2_0" prefix="portlet"%>
<%@ taglib uri="http://liferay.com/tld/theme" prefix="theme" %>

<portlet:defineobjects />
<theme:defineobjects />
