public abstract class PresentationData extends HashMap<Object,Object> implements IPresentationData, Serializable, Cloneable
An instance of this class is available on every request handled by the Portal servlet.
To access this instance, use the static method getPresentationData(javax.servlet.http.HttpServletRequest).
This instance is initialized with data useful in presenting a response to the request,
including
IPresentationData.getDataObject())IPresentationData.getResourceID())IPresentationData.getContextPath())
and servlet path (see IPresentationData.getCanonicalServletPath())The web-app context path is useful when drawing a link to a static web resource hosted by the portal, such as an image. To draw a link to an image in the portal war '/ui/images/' directory, you could use the following JSP snippet:
<img src="<%=presentationbean.getContextPath().length > 1
? presentationbean.getContextPath() + "/"
: presentationbean.getContextPath()%>ui/images/myimage.gif" />
<a href="<%=presentationbean.getFullServletPath()%>folder.public">
Public Folders
</a>
