Frequently, new Java™ applications can be developed more quickly and reliably by harnessing the power of existing (non-Java) CICS programs. A CICS connector is a software component that allows a Java client application to invoke a CICS application. Typically, the Java client programs that use a CICS connector are servlets.
For several releases, CICS has supported CICS connectors that enable a Java client program, running outside CICS (on, for example, Windows, UNIX, or native z/OS®), to connect to a specified program on a CICS server. The CCI Connector for CICS® TS enables a Java program or enterprise bean running on CICS Transaction Server for z/OS to link to a CICS server program.
