Setting up the CLASSPATH
Before you write any Java™ client programs, update the CLASSPATH environment variable to include the jar files supplied with CICS® Transaction Gateway.
CLASSPATH = <install_path>
/classes/ctgclient.jar;
<install_path>
/classes/ctgserver.jar
The ctgserver.jar file is required in CLASSPATH only for JavaGateways using the local URL.
