The Java 2 security manager

The security of the enterprise beans container environment is protected by the Java 2 security policy mechanism and is independent of CICS security. The security policy mechanism is one of the components that make up the Java 2 security model.

The security policy mechanism is used to enforce the restrictions in the EJB specification concerning Java functions that may not be issued by enterprise beans. CICS provides a policy file that enforces this behaviour.

To use JDBC or SQLJ from enterprise beans with a Java 2 security policy mechanism active, you must use the JDBC 2.0 driver provided by DB2® Version 7. The JDBC 1.2 driver provided by DB2 does not support Java 2 security, and will fail with a security exception unless you disable the mechanism.
