This is really a linux permissions issue.
How are you starting tomcat? with the $TOMCAT_HOME/bin/startup.sh or
with jsvc or are you using an ubuntu startup script?
You don't say anything about the user who will run the java application.
Generally, the way to control the access permissions with which files
are created in linux is to call 'umask' with the correct parameters. As
mentioned before on this list umask is a shell command, so you must do
it at the correct point or severely weaken the overall security of your
installation.
You need to do the following:
1. decide which user or users will be executing tomcat and the java
application.
2. If you decide that you need to have two separate users, then make
them both in the same group.
3. Use umask in the tomcat startup script and/or the shell in which you
run your application to set appropriate access permissions - GIYF
As an aside, if you are going to have two different processes writing
these shared files you may also have to consider locking issues - maybe
you have already done this.

Hi,
I'm running a WebService using Tomcat 5.5 on Ubuntu 7.10 with Axis2.
Files (and directories) are created by this service on a local directory:
/myfiles/
The permission of the new directories and files in this directory are:
Directories: 'drwxr-xr-x 2 tomcat55 nogroup 4096'
Files: '-rw-r--r-- 1 tomcat55 nogroup 10041'
The problem is, is I want to access (write) these files using, say, a java
application, it give me:
java.io.FileNotFoundException: /myfiles/aDir/aFile.txt (Permission denied)
How can I either:
1.Gain write access to these files (without having to constantly change the
permissions in the command prompt, and without running my java application
with 'root' access).
2.Create the files/dirs from tomcat with 'write access'
3.Other....
Thanking you in advance.
Daniel
