Accessing data from Java applications

You can write Java™ applications that can access and update data in DB2® and VSAM. Alternatively, you can link to programs in other languages to access DB2, VSAM, and IMS™.

You can use any of the following techniques when writing a Java application to access data in CICS®. The CICS recovery manager maintains data integrity.

Accessing relational data

You can write a Java application to access relational data in DB2 using any of the following methods:

Accessing DL/I data

To access DL/I data in IMS, your Java application must use a JCICS LINK command to link to an intermediate program that issues EXEC DLI commands to access the data.

Accessing VSAM data

To access VSAM data, a Java application can use either of the following methods:
