If it is okay with Jetspeed-2 specific API, then you can make use of RequestContext object which is a flyweight object only for the current page request: import org.apache.jetspeed.request.RequestContext; RequestContext requestContext = (RequestContext) portletRequest.getAttribute(RequestContext.REQUEST_PORTALENV); Because requestContext is shared among portal and portlets, you may use #setAttribute() and #getAttribute() and you don't have to remove attributes later in this case. requestContext object will be removed after the request.
