The JDBC 1.2 driver supports the JDBC 1.2 level application programming
interface. The JDBC 2.0 driver supports the JDBC 1.2 API and a subset of the
JDBC 2.0 API.The DB2 Universal JDBC Driver provides enhanced
support for the JDBC 2.0 API and most of the JDBC 3.0 API, and also supports
the JDBC 1.2 API. All three drivers support the SQLJ Part 0 (ANSI 98) level
API. Java™ programs for CICS® must adhere to the programming rules of these application
programming interfaces, which are more restrictive than the general CICS programming
model.
You can find more information about the JDBC APIs at the JDBC Web site, http://java.sun.com/products/jdbc. For information about the features of the JDBC APIs that are supported by the DB2®-supplied JDBC drivers, and how to code and build Java applications that use the JDBC and SQLJ APIs, see the DB2 Universal Database™ for OS/390® and z/OS® Application Programming Guide and Reference for Java which is appropriate for your version of DB2. The document number for DB2 Version 6 is SC26-9018, the document number for DB2 Version 7 is SC26-9932, and the document number for DB2 Version 8 is SC18-7414.
The particular programming features that apply to JDBC and SQLJ when used in a CICS environment are described in the following sections:
