Userdirs on an NFS share
Hi list,
I'm having a 404 error whenever I try to browse a JSP owned by a user
(eg: http://server:8080/~paul/test.jsp)
type Status report
message /~paul/test.jsp
description The requested resource (/~paul/test.jsp) is not available.
I guess the trouble comes from my NFS share, since users home
directories are stored on another server.
If I change the homedirectory to a local directory, it works fine.
If I use a context to the NFS share, it works too.
eg, in my server.xml:
<Context path="/~paul" docBase="/NFS/homes/paul/public_html/"
crossContext="true" debug="1" reloadable="true" />
But this doesn't work:
<Listener className="org.apache.catalina.startup.UserConfig"
directoryName="public_html"
homeBase="/NFS/homes/"
userClass="org.apache.catalina.startup.HomesUserDatabase"/>
I'm using Apache 2.2.9 (from debian lenny),
Tomcat 6.0.18
mod_jk 1.2.27
Users are refered in an LDAP directory (but of course, they are
recognized by the box and Apache mod_userdir since http://server/~paul
will display the right index.html)
Is it a bug?
Thanks for your help or any information.

Yes, but the whole directories in my NFS share are rwxr-xr-x, so I think
it should be ok...
/NFS (755)
/NFS/homes (755)
/NFS/homes/user (711) (but for the test, I changed it to 755)
/NFS/homes/user/public_html (755)
/NFS/homes/user/public_html/test.jsp (755)

Remember that over nfs, the client's access to the server will be as
user nobody or nfsnobody, depending on your system, so that user will
have to have access to all those directories/files, unless of course you
use the anonuid/anongid directives in your exports file.

Hello and thank you for your reply.
By now, I'm running it with the root user (I'm testing), but the NFS
share is mounted with the no_root_squash option.
However, from / till the public_html, all the directories have rx access
for everybody (and the .jsp as well), so I guess the files should be
readable. (Actually, if I remove the :8080 in the URL, the source code
is displayed, even Apache is running under www user)

I meant users home directories.
Actually, for this test, I unmounted the NFS share, then copied my own
home directory on the local filesystem (with the same rights).
Usually, I mount the NFS share on /NFS, but for this test I did:
umount /NFS
mkdir -p /NFS/homes/paul/public_html
vi /NFS/homes/paul/public_html/test.jsp
chmod -R 755 /NFS
Then on http://server:8080/~paul/test.jsp the jsp is executed.

What I meant by "doesn't work" is the symptom I described above: the
Tomcat 404 error:
type Status report
message /~paul/test.jsp
description The requested resource (/~paul/test.jsp) is not available.
The Listener is in the server.xml, inside the <Host>. Below, the whole file:
== server.xml ==

Sorry for my lack of details and thanks for your help.

Does the userid Tomcat is running under have access to the file in question? If not, you'll always get the 404.

What do you mean by "the homedirectory"? Tomcat's? The user's? Your own?
> But this doesn't work:

Where is the above <Listener> located? What does "doesn't work" mean? Be specific.
