Unable to connect to MySQL database

Question

Hello,
I have written a DatabaseManager class that controls access to a locally stored database, implemented in mysql. In theory, client request should be passed to the DatabaseManager through RMI, but I cannot even create a connection to the database yet!
Here's my connect statement:
con = DriverManager.getConnection("jdbc:mysql://127.0.0.1:3306/media", "mysql", "mysql");When this statement is executed, the following exception is produced:
java.sql.SQLException: Unable to connect to any hosts due to exception: java.security.AccessControlException: access denied (java.util.PropertyPermission file.encoding read)Can somebody explain to me how I successfully create a connection to the database? I would be extremely grateful. Also, could somebody explain how I could connect to the database from a remote machine using the following connect statement:
con = DriverManager.getConnection("jdbc:mysql://server:3306/media", "mysql", "mysql");I have a feeling I need to grant a certain PropertyPermission in my policy file, but I'm unsure of what values I should be using.
Thank you in advance.
Pete

Thank you for the prompt reply.
In answer to you question: No, it is not an applet. The DatabaseManager is a class that implements a Remote interface, I have it running on the same machine as the mysql database (the server). I then have a small GUI that runs on a client machine which is used to make RMI calls to the DatabaseManager across the network in order to query the database.
When the DatabaseManager object is spawned on the server, it tries to connect to the database to be ready for client queries. This is when it produces the exception mentioned in the original post.
What confuses me is that in my original implementation, the DatabaseManager object was run on the client and the mysql JDBC had no difficulty in connecting to the database across the network. Could the security manager have something to do with it? I am using the RMISecurityManager in conjunction with the java.policy file from the Java RMI tutorial on the Sun website.
