This information provides
an introduction to writing Java™ client
programs for the CICS Transaction Gateway.
Signing Applets and Web Start Applications
All Applets and Web Start applications must be signed with
a certificate from a trusted authority to run in a Java 7 environment.
Overview of the programming interface for Java
The CICS® Transaction Gateway enables Java client applications to communicate with
programs on a CICS server by providing base classes for the External Call Interface (ECI)
and the External Security Interface (ESI).
EPI and z/OS
The EPI classes are not available for z/OS®.
If you want to run transactions in the manner of the EPI, use the
ECI and set up a request for DFHWBTTA. This is described in the CICS Internet
Guide.
Compiling and running a Java client application
Issues to consider when compiling and running a Java client
application include performance, the Java class path and whether or
not you are running a Web browser on the same machine as CICS Transaction Gateway.
