public class DerbySQL
extends MXJ_SQL

This is a simple MXJ object which provides an SQL connection to an embedded Derby database. The database is started and stopped automatically.

The database is mapped to a small number of text files. We actually locate the text files by searching for a mandatory "place-holder" file in Max's search path. This makes more sense than some property declaration somewhere.

Constructor Detail

DerbySQL

public DerbySQL()

A constructor which bombs out unless it's been passed the name of the place-holder file.

DerbySQL

public DerbySQL(java.lang.String placeHolder)

Constructor. Build a connection, using the Max search path to find a place-holder file which specifies the location of the database files to use. (Note that we implicitly do a "connect()".)

Parameters:

placeHolder - the place-holder filename for the database path to use.
