The CICS/IMS Java™ Data Binding wizard enables you to
create a class or set of classes that map to COBOL or to C data structures.
The J2C Java Data Binding wizard assists you in creating specialized Java classes
representing the input and output messages of an EIS transaction from the
corresponding COBOL or C data structures of the EIS application program. These
specialized Java classes are called data bindings. Java data
binding classes are used as input or output types for invoking CICS
® or IMS™ functions.
Once you create the binding classes, you can use the J2C wizard to create
a Java bean
and to create a method within the bean that uses the binding classes, as the
following diagram illustrates:

Data bindings provide the Java application
the mechanism for populating the input message with data and for retrieving
data from the output message. The data bindings perform conversion between
the Java (UNICODE)
and host (EBCDIC) representations of the data.
