Thanks to the help I received from this mailing list,I am happily posting data into sling, and retrieving it with java queries. I have made several JSP fragments, and everything is working well. So for example, I am now able to make the list.jsp examples, which list me the child nodes under 'this' node, as long as the node has a sling:resourceType.
I would like to write a simple browser that fulfills the role that the jcr:explorer should. (the jcr:explorer project is sadly not working within launchpad. As you soon as you update a property such as sling:resourceType it dies. If you want I will raise a defect for this). To write my browser I have to be able to find the child nodes of an arbitrary node. With the small knowledge I have to date, this could be done if I guarantee that every node has the same sling:resourceType, as I could then write a MyList.jsp for that sling:resourceType. However I would like to increase my Sling-fu, and this seems like a good starter project. There is clearly a way to do this: the extensions .json/.xml/.html are using it. Is there a way to write my own equivalent so that I could call (say) http://localhost:8080/content.myList, and this be rediverted to MyList.jsp? The other approach I have is to go in through the webdav interface, and query for children. Do any of you have any suggestions for good reference material on how to do this? Thanks again for the help
