Code your applications

In your applications, you cause classes to be loaded the way you normally would:

In your applications, you load resources the way you normally would, using the standard java.lang.Class.getResourceAsStream, a mechanism that allows an application to access resources defined in the classpath without knowing where or how they are stored.

You do not need to make any changes to the way code interacts with Derby and its JDBC driver. An application can safely attempt to boot Derby, even though it is already running, without any errors. Applications connect to Derby in the usual manner.

Note: The method getResource is not supported.
