Re: class for BpropFindMethod
I could not have said this better myself. Ingo BPropfind allows you to arbitrarily specify resources that you want to do a propfind on. If all your resources are within a folder, then you can always vary the depth value to get all the information (and perhaps more). Microsoft is as usual trying to hijack the standard by introducing its own extensions (another extension is the brief: header). Given that they were a member of the RFC, it is despicable that they would knowingly introduce junk extensions like this.

Hia folks, Again, don't remember correctly in witch context someone said that slide would try to be MS-Compatible. At least I believe they meant MS-interoperable. Also, I too agree with Julian and you folks. What's the point in supporting MS extensions if they can change it over night? Worse! Poorly written and bug-enabled! That's the strength in industry standards, in witch we should depend: only the best thinkers contribute to a standard, making it mature. Also, a standard is used by everyone, not just by one big company, improving interoperability and reusability. I don't like monopolist entities, but Microsoft as cool products, really productive tools when .net came our way. Wouldn't mind programming .net if they would continue to support standards as they seemed to do these last years: but these Microsoft 'standard' extensions make me feel like I belong in the open source community, and that there will be a never ending fight between them and us, despite how cool their tools look like.

Re: class for BpropFindMethod
Hello All, Actually the reason to ask this question is we got a project related to JavaClient-MS Exchange Server Communication. After thorough investigation we find BPROPFIND as fast solution in our case One good thing is by extending PROPFIND class we are able to develop a class for BPROPFIND METHOD. Some people who loves/likes both MS products/Open Standards faces some problems. As MS products may try to hijak some of functionalities from open standards. In such scenarios Java (Open Source API always will be developed on Open standards) to MS products communication may be complicated. Anyhow we can leave this to slide developers as they know what to do and what not.

Re: class for BpropFindMethod
[Disclaimer: I am an MS fan] I'd rather say, MS saw the need for further methods like the BPropfind and saw that making this the standard would them *literally* take years. Judging from the WebDAV lists I think Julian has a better idea how long it takes and how much hassle it is to get out the WebDAV standard ;) Isn't it just like the SQL thing: Oracle wants this and that and starts by doing it. IBM wants that and this and starts doing it. *Later on* people discuss what will be a the standard, but both Oracle and IBM have their extended functionality right away. Bottom line: If Sudhakar manages to write something like a BPROPFIND method and wants to contribute it to Slide I would be +1 for doing so.

Re: class for BpropFindMethod
I wouldn't say NEVER EVER. I would say, if there is somebody who implements that, provides test cases and documentation this (an IETF document would be nice, but takes time) we can add this to slide. That the users of slide - responsable for its self - has to determine whether to use it or not. Actually slide contains always some MS extenstions: 1st external transaction which I found very usefull I my current project and 2nd subscriptions. For BPROPFIND I can imagine it may reduce the number of webdav request-response pair, and so may improve performance.

Versioning - Rolling back to a previous version of a Node
Hi Guys, I am trying to find a way to programmatically (i.e. via the Slide kernal API ) roll back to a previous version of a Node. What I am trying to do is basically the following: 1. Create Node (revision no 1) 2. Update Node (revision no 2) 3. Update Node (revision no 3) 4. Update Node (revision no 4) 5. Update Node (revision no 5) 6. Rollback to revision no 3 (i.e. discard modifications in revisions 4 5) I thought that I would be able to acheive this via the org.apache.slide.content.NodeRevisionDescriptors class as it has a setLatestRevision() method however this only has package level visibility so I can't invoke it from my classes. Is there any other way to perform this operation ? Thanks Andy Bowes - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: If ACL-inh=root, why cant user authenticate ?
I figured this out, to the extent that I keep the inheritance as described, but when I create a collection that must be invisible to /roles/user, I just change the Ace for that principal on that new collection to 'negative=true', execute an aclMethod with the new Ace array, and presto, elements of /roles/user are not able to access the resource. But, but, but, I still want /roles/root to be able to access the resource (for admin purposes). However, since root is a member of /roles/user, now root is excluded by the action just described above. Is there a way to exclude /roles/user and still allow /roles/root access ? The Dav spec, or Slide documentation, says that in the case of a conflicting permission (as here, where /roles/root has DAV:all and /roles/user has none) we end up with the /roles/user taking precedence (apparently). -Original Message- From: Nick Longinow [mailto:[EMAIL PROTECTED] Sent: Friday, October 01, 2004 12:13 PM To: 'Slide Users Mailing List' Subject: If ACL-inh=root, why cant user authenticate ?

I have used it in several projects and would like to adopt it for Sakai, but Sakai has some pretty high performance needs. As an example, Indiana University will run a site with 100,000 users and 10Million hits per day. I am wondering if there are some high perfomance installations of Slide that operate in that kind of environment. Feel free to drop me a direct e-Mail with a short summary of your installation. I really would like to use Slide because of its rich feature set and the fact that it is open source, but I am nervous about being the largest Slide installation on the planet and the fun that entails...

I debugged it and i figured out that when the first PROPFIND method is issued (to get the basic properties) the server won't respond. It also don't works if i restart the client.

Re: [Newbie] Slide performance and scalability
Hi Charles, I have no experience with installations that have requirements similar to yours. What I can tell you, however, is that it is most likely less work and more promissing to be successful to help tune *Slide* for better performance and scalability than to build something from scratch. Additionally, there are a lot of motivated people trying to bring Slide forward. You could benefit from this and help as well. I understand building something from scratch can be much more fun in the initial phase, but when it comes to the tough parts, I'd say you'd be much better of with Slide.

Re: External Transaction (as defined by MS) problem
Hi Zoltan, it is pretty hard to tell what is actually going on without seeing the code. I however suspect the PROPFIND is done on a resource that is still locked by another transaction that has not been committed or rolled back. As this is on the server side it is of no use to restart the client. Try to have something like a commit/rollback in finally blocks to make very sure all transactions are properly terminated. By the way, what is the underlying persistence store? Depending on this there are different ways to find out what locks are on what resources. Note that Slide does no additional locking when running external transactions. Hope this helps otherwise please show us the code, Oliver L Z schrieb: Hello slide users, I am using slide 2.1b1 server and client.

Hey all,
Going through the learning curve on Slide and on the WebDAV
client api/library.
I can successfully 'put' and 'get' binary files.
However, I'm having a hard time understanding how to add
properties to files for use in searching (and I'll ask now,
how to search on a property).
I'm guessing it is something with the 'proppatchmethod'
method(s), but can't find any good examples on how to use
these methods (and, in the same token, the propfindmethods).
Any examples please?
my code to-date:

WebdavResource wdr = null;
HttpURL hrl =
new
HttpURL(http://localhost:8080/slide/files;);
hrl.setUserinfo(root,root);
wdr = new WebdavResource(hrl);
if(wdr==null) {
System.out.println(WDR creation failed);
}
//use root-based dir structure. Windows
drive names cause issues (assume with colons)
String filename = /test3.tif;
File fn = new File(filename);
System.out.println(can read file? +
fn.canRead());
boolean writebol = wdr.putMethod(fn);
//directory-type listing

Perhaps slide mandates that to change an ACL, you must act upon the right resource (collection in this case). I would try this approach: get a WebdavResource instance of the 'folder' collection, and execute the AclMethod adding your read-deny ACE, for the right Principals (i.e. /roles/users/). If you are using root account, don't forget that root also makes part of the /roles/root/ Principal. Hope this helps, Miguel Figueiredo _ Hi I want to prevent users from browsing into a collection (folder) that contains documents, and so am trying to adjust the ACL for the collection.
