Problem with RepositorySession+Acegi

[walbar]

Hi all,

I'm writing a web page (using SpringMVC) which lists nodes from Alfresco, using JDK 1.4. It's a read-only page that keeps the repositorySession in the HttpSession and uses it several times. I refresh my page several times and it works fine, but if I leave it for a while (let's say 3 minutes) and then refresh my page I get the following:

Here's my controller:

protected ModelAndView handleLoggedRequestInternal(HttpServletRequest request, HttpServletResponse response)            throws Exception {        Node rootNode = SessionUtils.getRepositorySession(request.getSession()).getRootNode();        Node instancesFolder = rootNode.getNode("sy:instancesFolder");        NodeIterator i = instancesFolder.getNodes();        List<Node> list = new LinkedList<Node>();        while (i.hasNext()) {            list.add(i.nextNode());        }        return new ModelAndView("instances-view", "nodes", list);    }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

SessionUtils just brings the Repository Session from the HttpSession. It was saved there when the user logged.

Any comment would be of great help.

Thanks in advance.

Besides, after this exception, if I press refresh again, it works fine. Again if I leave it for a little while the exception reappears.

Thanks,
