I'm guessing, but based on my previous experience with Tomcat, you're
probably trying to write to a directory which Tomcat believes you don't
have permission to access.
Tomcat installs it's own SecurityContext which restricts each WAR to
have access to only certain directories.
You need to do something in the configuration to make it work.
Thomas, our problem is that FilePathDisk#createFile() cannot tell the
difference between
"access denied because of permission problem"
and
"access denied because of locking problem"
Perhaps when we start using the new JDK7 file API's, we'll be able to
tell the difference.

Hi,
That's strange. I never saw a case so far where the file locking
mechanism was hanging (either it works within a second or, or it
fails). Are you sure it actually hangs, or is it possibly just slow
(taking a second or so)?
What file system do you use? Maybe the last modified time doesn't
match the system time. I saw this in some cases (when using NFS for
example).
I don't recommend using FILE_LOCK=SOCKET because it is rather
dangerous as it relies on network connectivity and correctly
configured network settings. I would rather suggest to use
FILE_LOCK=FS. Could you try that?

Thomas

I am using H2 with default settings on Red Hat Enterprise Linux
and it causes my tocat server to hang. I created a thread dump and
it looks like H2 keep waiting for gaining lock over the database
file. No Exceptions anywhere. No deadlocks detected in thread
dump. I have tried using sun/Oracle JDK as well as Open JDK.
Please note the same application works fine under Windows 7,
ubuntu 12.04 and Cent OS 5.x
Solution to this was change it to use: FILE_LOCK=SOCKET
Now, can anybody tell me if I can use this or not? I have a single
application accessing the database.
