Myrna van Lunteren commented on DERBY-5146:
-------------------------------------------
The initial error you were getting is typically a network server configuration
issue.
Could be a mismatch between the OS-level permissions. I assume you've checked
that the user starting the network server actually can write in the
/home/user/dbbackup directory...
Or (my guess for this case) could be the result of some mismatch between what's
allowed in the security policy file used by the network server and what
directory you're telling it to write to.
The default policy file (part of derbynet.jar) gets you access to
derby.system.home, but can't know about other directories on your system.
You'll want to add a java.io.FilePermission for /home/user/dbbackup.
For more information on how to setup & run with your own policy file, see:
http://db.apache.org/derby/docs/10.7/devguide/devguide-single.html#cdevcbabejdfj
To see more information about the default policy file see:
http://db.apache.org/derby/docs/10.7/adminguide/adminguide-single.html#tadminnetservcustom
To review how to modify the policy file to provide access to
/home/user/dbbackup, see:
http://db.apache.org/derby/docs/10.7/adminguide/adminguide-single.html#tadminnetservcustom
Please close this issue if this gets you over the bump.
Otherwise, please provide more details, such as your policy file in use,
permissions of the directory involved, whether or not this has worked before on
this system or other systems, contents of derby.log (there will be a stack
printed out somewhere).
