Accessing IMS data from CICS with the classic Java APIs for IMS
The following information covers how a JCICS application can access IMS™ data using the classic Java™ APIs for IMS.
Recommendation: 
Customers using
these APIs should migrate to the IMS Universal
drivers. IMS Version 13 is
the last release to support the IMS classic Java APIs. Because the IMS Universal
drivers are
built on industry standards and open specifications, and provide more
flexibility and improved support for connectivity, data access methods,
and transaction processing options, use the IMS Universal
drivers for
developing your Java applications
to access IMS.

To deploy a Java stored procedure on CICS® Transaction Server for z/OS®, you must configure the classic Java APIs for IMS and DRA. For details on completing this task see the "Loading and running the ODBA and DRA modules in the z/OS application region" topic in IMS Version 13 Communications and Connections.
