Each programming language has its own control block structure mapping. All mappings and header files are stored in SEZANMAC, and the C language headers are also installed in file system directory /usr/include. The Java™ API classes are installed in the directory /usr/include/java_classes, and the dynamic link library (DLL) files are installed in the directory /usr/lib. The following programming languages are supported:

Assembler

Include the EZBPINFA mapping.

C

Include the EZBPINFC header file.

Java

Include the EZBTrustedPartner.jar file.

PL/I

Include the EZBPINF1 mapping.

COBOL

Include the EZBPINFB mapping.

REXX

No mapping or header file is used.

  Download the jar file to a workstation, unpack it, and read it in a web browser. The trusted TCP connections API for Java includes the ConnectionType and PartnerInfo classes.

  Optionally for logging, see the information for the java.util.logging package; the trusted TCP connections API for Java uses the Java logging API (java.util.logging.Logger) to generate debug information.
