When you create a WebdavResource there is a ctor with an action parameter, there is also a setDefaultAction() method. An action of WebdavResource.NOACTION will prevent any lookups from occurring and as a side effect, make many of the WebdavResource property tests no longer function. I use the NOACTION parameter almost exclusively because I don't like the problems I had with the alternative and I don't want to query the server multiple times if I need additional properties. It would be possible to modify (heavily) the WebdavResource class to get the best of both worlds, behind the scenes property population on demand with no overhead if you don't use them but I have never had the time to pursue it.
A note on existence checking. I accomplish my existence checks by reading a standard property, in my case DISPLAY_NAME, and trap any errors that occur when it is not found. If the property doesn't exist for the path, then the object doesn't exist. It is not wise to use this as a form of duplicate checking prior to a create operation, because the create could still fail due to a duplicate exception. -----Original Message----- From: Lixin Chu [mailto:[EMAIL PROTECTED] Sent: Wednesday, March 22, 2006 8:52 PM To: Slide Users Mailing List Subject: Re: How to test is a folder exists ? Hi Ray, >>You can tell WebdavResource not to do the default lookups, How do I do this ? I went through the API but did not find something close to do this. >>but you end up having other problems in that case. Can I set to 'do not load property' before calling setPath(), then set to 'load property' before calling exists() ? thanks lixin On 3/21/06, Ray Sprinkle <[EMAIL PROTECTED]> wrote: > By default a WebdavResource loads a set of properties from the server > when it is created or the path is changed.
