You could read those values from a file, or you could prompt the user with a console or graphic user interface (GUI).

If developing the web application ,write the in the web.xml as <context-param>

Welcome to the Ranch

Can you put them into your database with the password() function? That stores a hash, which you can't reconstruct the password from.

I think you misunderstood. Shakuntala is talking about the username / password to use to connect to the database in the first place.

They need to be stored in some external way; a resource file inside the JAR file, a configuration file (preferably using XML or java.util.Properties), the Windows registry (using a third party library or java.util.prefs.Preferences), etc.

Eventually in order to make it configurable, password must be in some properties/xml file. I suggest you can keep it in an encoded form in a properties file. You can decode the same in your Java code while making a DB connection

Yes, I had the wrong password. Sorry.
