The " Embedded Derby " section shows how to turn the same code into an embedded application. When executed with the derbyclient argument, the SimpleApp application loads the Derby Network Client driver with this code:.

When executed with the derbyclient argument, the SimpleApp application creates and connects to the derbyDB database with this code:.

If you look at the SimpleApp. When connecting via the Network Server, other applications might be accessing the same database you are; so, don't shut down the databases or Derby.
