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