1.1 What is Java Service Manager (JSM)?

The Java Service Manager:

  • Allows integration of Java programs with existing LANSA or 3GL applications.
  • Provides a standardized interface for calling Java classes using Java service programs. When a service is loaded into the JSM, it manages the interface to the services, handles the threading and provides tracing.
  • Greatly simplifies the development of server applications requiring the integration of Java Services with LANSA or 3GL applications.

The Java Service Manager can be used by:

  • LANSA functions (by using LANSA Built-In Functions (BIFs)).
  • LANSA functions being executed over the Internet using HTTP.
  • ILE programs (by calling the Java Service Manager APIs - similar to BIFs).
  • Other Java classes.

Some of the services shipped with the Java Service Manager are:

  • XMLBindFileService (Local XML file handling).
  • XMLBindQueueService (MQSeries XML message handling).
  • HTTPService (Generic HTTP service with dynamic content handlers).
  • FTPService.
  • POP3MailService.
  • SMTPMailService.

The JSM includes Java classes for standard requirements such as exception handling, message handling, data conversion, etc.
