To manage preferences in your portlet you need to add preferences in your portlet.xml in this way: | <portlet> | <portlet-name>YourPortlet</portlet-name> | <portlet-class>org.yourcompany.portlet.content.YourPortlet</portlet-class> | <supports> | <mime-type>text/html</mime-type> | <portlet-mode>VIEW</portlet-mode> | </supports> | <portlet-info> | <title>Your Portlet Title</title> | </portlet-info> | <portlet-preferences> | <preference> | <name>numberContactPerPage</name> | <value>10</value> | </preference> | </portlet-preferences> | </portlet> | Then in your portlet you can use this snippet: | public void processAction (ActionRequest request, ActionResponse | actionResponse) | throws PortletException, java.io.IOException { | PortletPreferences pref = request.getPreferences(); | pref.setValue("15",request.getParameter("numberContactPerPage")); | pref.store(); | actionResponse.setPortletMode(PortletMode.VIEW); | actionResponse.setRenderParameters(request.getParameterMap()); | } | Hope this helps.
