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