回复： RE: portletPreference question
I use the distribution jetspeed-2.0-M3-Tomcat-5.5.9.i've never change any web app within this distribution. you see that bookmark portlet locate in app demo.
BookmarkPortlet is in my computer:
D:\jetspeed-2.0-M3-Tomcat-5.5.9\jakarta-tomcat-5.5.9\webapps\demo\WEB-INF\classes\org\apache\portals\applications\desktop\BookmarkPortlet.class
I just change something following what i have said.
Here is BookmarkPortlet code:
/**
* BookmarkPortlet
*
* @author <a href="David'>mailto:taylor@apache.org">David Sean Taylor </a>
* @version $Id: BookmarkPortlet.java,v 1.1 2004/11/19 21:53:12 taylor Exp $
*/
public class BookmarkPortlet extends GenericServletPortlet
{
public void processAction (ActionRequest request, ActionResponse actionResponse)
throws PortletException, java.io.IOException
{
String removeName = request.getParameter("remove");
if (removeName!=null)
{ // remove
PortletPreferences prefs = request.getPreferences();
prefs.reset(removeName);
prefs.store();
}
String add = request.getParameter("add");
if (add!=null)
{ // add
PortletPreferences prefs = request.getPreferences();
prefs.setValue(request.getParameter("name"),
request.getParameter("value"));
prefs.store();
}
}
}
BookmarkPortlet section in portlet.xml:
......

I use user1 logon jp2.then I add a new PortletPreference pair:the key user1,value user1,not in portlet.xml but using the portlet bookmarkportlet itself .when user2 logon jp2,it can get all what other user have changed within BookmarkPortlet.
how i understand the conception user. it means account registed in portal system or web page id such as session id.
and who can tell me the relation among these conception in jp2 : portlet.xml,portletdefinition,portletentity,portletwindow . someone providing some concreate jp2 example is best.

The way it is working for us is we have them in the portlet.xml, which creates a default set of preferences for the user. When we change them per user, it stays that way. When a new user enters the system, the default preferences are copied over for the user.
I do want to put some code in, though, that would add new preferences on the fly (the JSR spec says it can be done, so I'm presuming it can, haven't tried it yet). I hope those are handled in this fashion. That a new user would only get the defaults that are in the portlet.xml, and NOT get the new ones added for another user...
We shall see!!
