> After creating 3 databases under c:\databases\sample - I wanted to get a list of available databases, I followed the example in the "DriverPropertyInfo array example" in the developer guide and used the following routine:
> ...
>   private static void test2() {
>     String driverName ="org.apache.derby.jdbc.EmbeddedDriver";
>     String url = "jdbc:derby:";
>     Properties p = System.getProperties();
>     p.put("derby.system.home", "C:\\databases\\sample");
>     p.put("derby.system.bootAll", "true");
>     try {
>       Class.forName(driverName);
>       Driver driver = DriverManager.getDriver(url);
>       Properties info = new Properties();
>       DriverPropertyInfo[] attributes = driver.getPropertyInfo(url, info);
>       for (DriverPropertyInfo attribute : attributes) {
>         System.out.print(attribute.name);
>         System.out.print(" : ");
>         if (attribute.choices != null) {
>           System.out.print(Arrays.toString(attribute.choices));
>         }
>         System.out.print(" : ");
>         System.out.println(attribute.value);
>       }
>     }
>     catch(Exception exp) {
>       exp.printStackTrace();
>     }
>     try {
>       DriverManager.getConnection("jdbc:derby:;shutdown=true");
>     }
>     catch(Exception exp) {
