Creating a directory from a webapp
Hi,
Within my webapp, I try to create a new directory on the file
system by using File.mkdir(). This webapp has the permissions
read write on the parent directory:
grant codeBase file:${catalina.base}/webapps/myapp/- {
permission java.io.FilePermission /somewhere/-, read,write;
}
The creation fails, but of course, I do not have any info
(because mkdir returns true or false instead of throwing an
exception).
Is there anything else I could check out? I cannot find any
clue of what I did wrong.
Regards,

Can you run Tomcat with something that traces system calls? strace(1) on
most UNIXes, Process Explorer on Windows. Then you can see exactly what
mkdir call is being issued - or, if none is issued, you can see that and
chase down why.

File.mkdir() Try with File.mkdirs() Note, that catalina.policy is only used when you are running with a SecurityManager enabled. (Many people run without it).

But the parent dir does exists and yes, I've tried that without success ;-) Note, that catalina.policy is only used when you are running with a SecurityManager enabled. (Many people run without it). Yes. But it is enabled (this is a virtual box with the Tomcat fro the APT system on a Ubuntu server, which will be at the end of the day in production). I will try to use strace(1) to get more infos. I suspect that's a permission issue. Is there a simple way to disable the security manager in order to be sure this is such an issue?

There is a setting somewhere. I do not run Ubuntu and thus do not know
exactly, but it was mentioned several times in the archives of this
list.
At least, you can replace your catalina.policy with
grant {
permission java.security.AllPermission;
};

Good to know, thanks for the hint!
In the meantime, using strace, I figured out what the problem
was: as simple as a wrong owner of one of the parent directories.
I must admit I am not really proud of this, but well, there is no
diagnostic at all with mkdir() :-(
Thanks all,
