file read/write permissions

[John Mack]

Hi, my question is:
In the server (or client) security policy file, do you have to give the db.db file a java.io.FilePermission setting?
I pass the location (as a full pathname) of the db.db file on the command line so that I can create a Data object. If I don't specify the full pathname of this file in the security policy file I get a 'java.security.AccessControlException: access denied (java.io.FilePermission..'
The problem is that the specification states 'allow the user to specify the location of the database', so if they move the database, the location will differ from the location in the policy file, and this exception will occur. Is there any way of setting policy file attributes after starting the program, or is there another way of making sure there is access to the file, wherever it is, without using 'permission java.security.AllPermission' which I don't think is a good idea.
please advise!

I just put one permission in my policy file that gave full access to everything.
grant {
permission java.security.AllPermission "", "";
};

I didn't lose points for it.

Hi Mark,
thanks for your reply. I have got a policy file now that basically allows all access to the files below the current user directory. But,if it goes pear-shaped it's good to know I can use the simple permission and not lose marks.
