is a JDBC driver for informix available? On the IBM website there was the latest version 3.70 I think, but I couldn't recognize if the the 3.70 is the JDBC version. Does anybody know if JDBC 4 driver is available?
3.70 refers to the Informix Client version not the JDBC compliance/standard version. Informix JDBC 3.70 driver is JDBC 3.0 compliant but not 4.0. If you need to use the JDBC 4.0 compliant APIs, you can consider using the IBM Data Server driver for JDBC and SQLJ (JCC).
