Saludos colegas
Tengo un problema al intentar obtener las preferencias de un portlet (el cual extiende de MVCPortlet) desde el método init().
Buscando por los foros, encontre el siguiente hilo: http://www.liferay.com/community/forums/-/message_boards/message/4929380
en el cual se propone utilizar una DynamicQuery
1
2ClassLoader cl = PortalClassLoaderUtil.getClassLoader();
3DynamicQuery query = DynamicQueryFactoryUtil.forClass(
4 PortletPreferences.class, cl).add(
5 PropertyFactoryUtil.forName("portletId").like("%LineChart%"));
6
7List<Object> preferences = PortletPreferencesLocalServiceUtil.dynamicQuery(query);
8
9System.out.println("Preferences are: " + preferences
10 + ", size is: " + preferences.size());
11
12for (Object preferencesPart : preferences) {
13 System.out.println(((PortletPreferences) preferencesPart).getPreferences());
Sin embargo esto genera una ClassNotFoundException:
1

Mi consulta es si me falta importar/declarar alguna librería, o debo obtener el ClassLoader de alguna otra forma? ya que desconozco a que JAR pertenece la clase javax.portlet.impl.PortletPreferencesImpl
