The JDBC 2.0 Optional Package (formerly the JDBC 2.0 Standard Extension API) defined
several features that JDBC 2.0 drivers could implement.
SAP jConnect version 6.05 and later have implemented several of these optional
package extension features:
JNDI for naming conventions – works with any SAP DBMS supported by SAP
jConnect
Connection pooling – works with any SAP DBMS supported by SAP jConnect
Distributed transaction management support – works only with SAP Adaptive
Server
SAP recommends that you use JNDI 1.2, which is compatible with Java
1.1.6 and later.
