Subject Re: Setting up Access Control
Date Wed, 14 Sep 2011 08:28:27 GMT
I tried to start from scratch as you suggested (a simple Java project with
the jackrabbit standalone .jar as library). Then i execute the following
code (from the updated Wiki section) logged in as admin:

    public Node createFolder(String username, String path, String

        Node actualNode;
        try {
            // Absolute path REQUIRED
            actualNode = session.getNode(path);
            actualNode = actualNode.addNode(foldername, "nt:folder");
            // Node HAVE TO exist prior to ACL setting
                              // Username value is "admin" or any other
            *setAcl(new PrincipalImpl(username), actualNode.getPath());*

        } catch (PathNotFoundException e) {
            return null;
        } catch (RepositoryException e) {
            return null;

        return actualNode;

    private void *setAcl(Principal p, String path)* throws
UnsupportedRepositoryOperationException, RepositoryException {

        AccessControlManager aMgr = session.getAccessControlManager();

        // create a privilege set with jcr:all
        Privilege[] privileges = new Privilege[] {
aMgr.privilegeFromName(Privilege.JCR_ALL) };
        AccessControlList acl;
        try {
            // get first applicable policy (for nodes w/o a policy)
            acl = (AccessControlList)
        } catch (NoSuchElementException e) {
            // else node already has a policy, get that one
            *acl = (AccessControlList) aMgr.getPolicies(path)[0];*
        // remove all existing entries
        for (AccessControlEntry e : acl.getAccessControlEntries()) {
        // add a new one for the special "everyone" principal
        acl.addAccessControlEntry(p, privileges);

        // the policy must be re-set
        aMgr.setPolicy(path, acl);

        // and the session must be saved for the changes to be applied


Executing the code above i get  the following exception (caused by the code
above highlighted in red colour):
java.lang.ArrayIndexOutOfBoundsException: 0
    at com.solaiemes.filerepository.starting.Permisos.main(Permisos.java:70)

Hope to be clear enough, if i am not please tell me and i will try to
describe it better.

Thanks for your attention!
