Greetings all. I need to execute some JDBC calls across the internet. I'm planning on using the getConnection method of the DriverManager. This requires a userid and password. How can I pass the userid and password securely?

Also, the URL parameter description in the DriverManager.getConnection method says "a database url of the form jdbc:subprotocol:subname. What would go in the subprotocol and subname fields? Thanks all.
