Redundant code. In the constructor of DataExtract (which extends ConnectionUtils ) you have. super(jdbcParams); this.jdbcParams = new JdbcParams(jdbcParams);. and in the constructor of ConnectionUtils you have. this.jdbcParams = new JdbcParams(env);. Also, I would expect the name of the. If anyone looks for a very simple file based database try this older low-level database which is very easy to understand. It is a tutorial, but you can download the full source code here. Basically it uses a simple RandomAccessFile and standard java serialization, so you can store everything serializable and. JdbcOdbcDriver ) is used for JDBC programming. Some of the Java's JDBC features do not work on Access - due of the the limitations in the JDBC-ODBC bridge driver. Access has various versions, such as Access 2010, Access 2007 and Access 2003, which are NOT 100% compatible. The file type for Access 2003 (and.
