Code for setting Derby's home

Details

According to John O'Conner (see sources), if you set the Environment Variable derby.system.home to a directory, Derby will look in that directory for any named database. It has to be said that I haven't had a lot of luck with it, despite setting the Environment Variable fine. Anyhow, I thought you might like to have a play with it - if nothing else it shows how to get the user's home directory.

Code

	// Initiate the database driver.
	try {
		Class.forName("org.apache.derby.jdbc.EmbeddedDriver");
	} catch (ClassNotFoundException e) {
		e.printStackTrace();
	}

	// Get the user's home directory and set the Environment Variable.
	String userHomeDir = System.getProperty("user.home", ".");
	String systemDir = userHomeDir + "/.database";
	System.setProperty("derby.system.home", systemDir);
	
	// Connect to a database called 'Results'
	Connection conn = null;
	String strUrl = "jdbc:derby:Results";
	try {
		conn = DriverManager.getConnection(strUrl);
	} catch (SQLException sqle) {
		sqle.printStackTrace();
	}
