annotate src/main/java/nl/cwi/monetdb/jdbc/MonetConnection.java @ 93:eeb71f7d36bf embedded

Fixed a bug on the JDBC MAPI connection from the old code! Fixed the connection properties for an JDBC Embedded connection. To start a JDBC Embedded connection, the user must start the embedded database beforehand with the method MonetDBEmbeddedDatabase.StartDatabase().
