I have created a page. In jsp of that page I have included components using <%cq:include%>. Inorder to load all the component node in jcr:content I have to open that page in siteadmin. whithout opening that page how to get jcr:content nodes ?

I have templates x,y,z. When ever I created a page using x or modified the page which is created by using template x  then an event should be called. When I create page using template y then no event should be call. Can any one help me how to do it ?

How to solve javax.jcr.NamespaceException: namespace is not registered?

Can you try using EventHandler. which will trigger upon deactivating page or changing property of node.
