Add property to a folder

[Rencana Tarigan]

Hi all,
I have code to add property to a folder or file at jackrabbit like this :
DavPropertySet newProps = new DavPropertySet();
        DavPropertyNameSet removeProperties = new DavPropertyNameSet();
        DavProperty<String> testProp = new 
DefaultDavProperty<String>(propKey.replaceAll(" ","_"), propValue, 
DavConstants.NAMESPACE);
        newProps.add(testProp);
        PropPatchMethod proPatch = null;
        boolean b_returnCode = false;
        try {
            proPatch = new PropPatchMethod(FileShipUtils.getInstance()
                    .getFullPath(remotePath.substring(-1)), newProps, 
removeProperties);
            //client.getParams().setAuthenticationPreemptive(false);

            client.executeMethod(proPatch);

            //System.out.println(proPatch.getStatusCode() + " "    + 
proPatch.getStatusText());
            //proPatch.checkSuccess();
            b_returnCode = true;// success
            proPatch.releaseConnection();

        } catch (IOException e) {
            e.printStackTrace();
            b_returnCode = false;
        }

This code is success to add property to a file but not work to a 
folder/collection, any suggestion for this problem ?

Thanks.
