[jira] Created: (JCR-1571) JCR Webdav Server doesn't support node.hasNode() method

JCR Webdav Server doesn't support node.hasNode() method
-------------------------------------------------------

                 Key: JCR-1571
                 URL: https://issues.apache.org/jira/browse/JCR-1571
             Project: Jackrabbit
          Issue Type: Bug
          Components: sandbox
    Affects Versions: core 1.4.2
         Environment: JDK 1.6; Tomcat 6; Windows 2003
            Reporter: Julio Castillo


I have a set up that uses the JCR Webdav Server from a custom remote client.
I've noticed one thing, anytime I request a node that doesn't exist the error that comes back from the server is as follows:

[Fatal Error] :1:941: The element type "HR" must be terminated by the matching end-tag "</HR>".
javax.jcr.RepositoryException: The element type "HR" must be terminated by the matching end-tag "</HR>".: The element type "HR" must be terminated by the matching end-tag "</HR>".

Doesn't really make sense, but that is OK, I can handle that.

My problem:
I have a partially populated repository that at the root has a few nodes like
/edu/....
/com/ibm/..

So, I want to create a few nodes of type nt:folder under

com/myCompany/folder1

I have no problem creating them, but since "com" already exists I end up with
com[2]/myCompany/folder1.

So, I went ahead and used the parentNode.hasNode("folderName") method.

This method returns true for the "com" portion, but when I test for the "myCompany" folder which should return false I get the error response shown above from the server.

The webdav request looks as follows:
PROPFIND /jackrabbit/server/default/jcr%3aroot/com/myCompany

The snippet of code looks as follows:
  private Node createFolders (Session session, Node parentNode, List <String> folders)
          throws RepositoryException {
    Node folderNode = null;
    for (String folder : folders) {
        if (parentNode.hasNode(folder))
            folderNode = parentNode.getNode(folder);
        else
            folderNode = parentNode.addNode(folder, "nt:folder");
        parentNode = folderNode;
    }
    session.save();
    return (folderNode);
  }

julio, could you attach the http-conversion? that would make it easier for me to
track the problem.

thanks in advance!

--------------------------------

    Attachment: trace_JCR-1571.txt

Angela,
attached are the excerpts of 2 PROPFIND http requests:
first one searching for the node /com which it finds and the second one searching for the node /com/myCompany which will not find because it doesn't exist.

Let me know if you need more information.

-----------------------------

hi julio

first of all: i don't think that the <HR> is sent by the JCR-server.

i quickly tried it out having the attached test cases:

test 1) creating a 'myTest' node -> save -> new session -> parent.hasNode should return true
test 2) same as 1) by trying parent.hasNode without the node being created before.

both work for me as expected... did i misunderstand your test? please let me know.

Julian Reschke commented on JCR-1571:
-------------------------------------

What happens here is that the servlet container generates an error page for the 404 status, and sends it out as text/html.

The client component seems to try to parse it as XML, which of course fails.

-------------------------------------

Angela,
Yes that is the process to reproduce the problem (test on a node that
doesn't yet exist -BTW, I created my repository by using the "Populate" link
in the default Jackrabbit deployment of the war file.

I don't know if the comment from Julian Reschle is sufficient to isolate it.
These are some notes on your log and mine
- I do see HR tags in the response from the server
- The version of the http client you are using is different from mine (I'm
running 3.1 -although I don't think this is the problem)
- You are using a different version of the servlet container (I am using
Tomcat)

Let me know if you need more information from me.

Thanks

** julio

that's fine (an probably does something similar as my manual test)

i guess it is.

yes. but i'm quite sure, that they are not generated by the webdav servlet.

nor do i. httpclient 3.0 is the version used with the spi2dav project.

yes. and i assume, that it is tomcat that generates the html error
page... and i assume that there is a way to turn that off as it should
be possible to configure a custom error page. can you try that?

Wait.

It's perfectly ok for a server to send a text/html response body with a 404 status. The client really needs to be able to deal with that!

angela commented on JCR-1571:
-----------------------------

if there is a simple way to disable the HTML (which the servlet did not generate), i don't want
to spent a lot of time extracting the original response body created by the servlet. it's a
sandbox project...

Julian Reschke commented on JCR-1571:
-------------------------------------

(talked to Angela on the phone, summarizing)

- for a non-success code, it's ok for the server to return text/html

- in Angela's case (see trace), this did not cause problems as the response body appears to be wellformed XML anyway (although HTML)

- the code that handles responses and tries to extract error details should handle this case as non-fatal; there's simply no information in addition to the HTTP status code available
