The Ingres JDBC Driver is a pure Java implementation of the JDBC 3.0 API - see below for Java version support. The driver supports application, applet, and servlet access to Ingres data sources through the Ingres Data Access Server (DAS). The Ingres JDBC Driver is delivered as a single Java archive file, named iijdbc.jar, located in the library directory (lib) of the Ingres instance. Depending on the Java environment used, access to the driver requires adding the Java archive to the CLASSPATH environment setting or as a resource in the appropriate utility. For browser/applet access, the Java archive must be copied to the Web Server directories.
The Ingres JDBC driver enables JDBC-enabled applications to access Ingres RDBMS, Ingres Enterprise Access and Ingres EDBC databases.
