Sharing stored information through diff portlets on jboss-po

[felipefo]

Hi,

For now I'm using this code bellow to store information and retrieve specific info of the portlet, but I would like two share this variable through diff portlets and also have this stored, like to portlets sharing the same stored variable.
Is there a way to do that ? I'm using jboss-portal-2.6.4.

public void processAction(ActionRequest request, ActionResponse response) throws PortletException {

 PortletPreferences preferences = request.getPreferences();
 preferences.setValue(MY_VAR, (String) request.getParameter(MY_VAR));
 try {
 preferences.store();
 ......

Thanks.
