RE: Problem with "proppatchMethod" for property "group-member-set
"
James,
Your trick # 1 worked. I had to use the same method that the
commandline client was using. Here is the method I used to make it work. I
could keep the CDATA element.
Code that worked:
============================================================================
====
PropertyName pName = new PropertyName("DAV:", "group-member-set");
if(webDavResource.proppatchMethod(sRolePathURI, pName,
sbNewMemberSetProperty.toString(), true))
{
write("Prop patch worked");
bSuccess = true;
}
============================================================================
====
I appreciate your timely help .....
thanks,
Krishna

Two things to try:
1) Look at the code the command line client uses to send proppatches to
the server. The client library supports multiple methods for most
operations, and whichever one the command line client uses seems to get
the most testing ::shrug::.
2) Try dropping the enclosing <!CDATA[ ]]>. I could be wrong, but I
don't think it's necessary, and it may be interfering.
Post back to list after you've looked at those two options. Maybe with
more data to go on someone who knows the client library well will be
able to give you a better answer.

James,
I did not get any responses from anyone, i am assuming no one
has
tried this yet. What is your opinion, I did some debugging and found
that
Webdav Client is doing its job of sending data to servlet. I think Slide
Server is not handling the XML data for group-member-set property
properly.
Can you please let me know what you think about this issue .....
thanks,
Krishna

Subject: Problem with "proppatchMethod" for property "group-member-set"
Hi,
I am writing a wrapper on top of WebDav Client 2.1 M1 (with
latest
CVS code for DOMUtils.java). I am having a problem executing
proppatchMethod() for the property "group-member-set". I am trying to
assign
user "john" to role "root". If I try the same through DAVExplorer 0.9,
it is
working fine. The group-member-set property value that my algorithm
generates before it calls proppatchMethod is:
The group-member-set property value that I am trying to set using
webdavResource.proppatchMethod
============================================================================
[CDATA[<D:href xmlns:D='DAV:'>/Slide/users/root</D:href><D:href
xmlns:D='DAV:'>/Slide/users/john</D:href><D:href
xmlns:D='DAV:'>/Slide/users/guest</D:href>]]
============================================================================
I get the following error:
============================================================================
[CDATA[<D:href xmlns:D='DAV:'>/Slide/users/root</D:href><D:href
xmlns:D='DAV:'>/Slide/users/john</D:href><D:href
xmlns:D='DAV:'>/Slide/users/guest</D:href>]]
Prop patch failed::Bad Request (400)
============================================================================
If I take this same string and add the property through DAVExplorer it
works
fine. So I am sure that the string that I am generating for the property
is
right. I guess there is a bug with the Slide2.1 M1 Webdav Client while
handling XML data.
Has anyone worked on this, any clues what could be wrong, or can anyone
validate that this is a bug with Webdav Client .....
any help is appreciated ...
thanks and regards,
Krishna

James,
Please ignore my e-mail, I looked at the CVS web site and it
was
pretty clear how to download the latest and greatest source code, I
will try
with the latest code and get back to you .... thanks a bunch!

You'll need to get it from CVS or wait until August 10 for the next
beta
release. The actual change was made to the DOMUtils class in
org.apache.util.

Hi James,
I am writing a wrapper on top of webdav client for our
application.
I am using Slide2.1M1. I found that the propfindMethod call on
property
"group-member-set" is always returning blank string. In the archived
discussion you had with Oliver
(http://www.mail-archive.com/slide-user@jakarta.apache.org/msg06713.html),
you were saying that you fixed this and that you had a patch that
solves
this problem, where can I find the patch?
Code
============================================================================
============
String sPropertyName = "group-member-set";
Enumeration enumProperties =
webDavResource.propfindMethod("group-member-set");
String str =
(String)enumProperties.nextElement();
str = str.trim();
write("Property = index of root = " +
str +
str.length());
============================================================================
============
kind regards,
Krishna
