Method Detail

getHeadPresentationContext

public static HeadPresentationContext getHeadPresentationContext(HttpServletRequest request)

This is a convenience method for returning a reference to the one and only HeadPresentationContext. Note this method will only work if called from within a portal (typically, from the head.jsp skeleton). This method may return null if called when no appropriate context exists, but such a context should safely exist when being fetched from the associated skeleton JSP during normal portal rendering.

Parameters:

request - The current HTTPServletRequest instance

Returns:

A reference to the current HeadPresentationContext, if any
