If you ask the engine to open a non-existent database file (using either server mode -database option or a stand-alone mode JDBC URL), the file and containing directory will be created.

I've included a main method in the TwitterSearchConnector class so you can test the class's functionality in stand-alone mode without needing to run Bonita. Listing 5 shows the main method.

Stand-alone is the preferred mode for many embedded applications.
