I finally found the 4.1.19 version of Tomcat, and its behavior is somewhat better:
Using the Tomcat with its build-in webdav allows me now to move and copy folders and bunches of files, although it still throws this fatal error message ([Fatal Error] :-1:-1: Premature end of file) when navigating in those folders.
Using my own webdav running as an ordinary servlet, however, does create the folders and sub-folders, but doesn't copy the files into them (a warning window pops up reading something like "Error while copying one or all of the selected files").
I traced that problem being in the doPut() method. The input stream actually comes in, but the bind failes.
The actual code snippet of the DefaultServlet class:
try {
Resource newResource = new Resource(resourceInputStream);
// FIXME: Add attributes
if (exists) {
resources.rebind(path, newResource);
} else {
resources.bind(path, newResource);
}
} catch(NamingException e) {
result = false;
}
Here, newRecource is well created, but resources.bind throws an exception.
What am I doing wrong?

I have set up Tomcat 4 on my Win2000 workstation (using jakarta-tomcat-4.1.18).
Using webdav via webfolder seems to work fine with single files, so does creating folders "manually" in the webfolder. However, when dragging and dropping a folder with several subfolders and some files in it I sometimes get the following error message printed on the Tomcat console:
[Fatal Error] :-1:-1: Premature end of file.
The folder than is copied incompletely, some files of the subfolders are missing.
Is that a known behavior, or just a bad configuration of my system? Does anybody have an idea how I could solve this problem?
As background information, I'm currently working on extracting the webdav module from Tomcat in order to make some project-specific changes to it. With this version, this error occurs much more frequently, which speaks for a configuration thing?
As far as I have traced it, this message is thrown inside the doPropfind method of the WebdavServlet class, seemingly at
Document document = documentBuilder.parse
(new InputSource(req.getInputStream()));
Anybody an idea?
There was a bug in the cache invalidation in 4.1.18 with subcontexts (folders). This could cause that. Try to see if 4.1.19 works better, or do a quick try by disabling the cache for your context (which will likely make the performance bad, but at least that would indicate that this was the problem).
