Components are critical parts of the server, and must adhere strictly to the programming standards listed in Programming Your Applications in iWay Service Manager. Components are expected to operate with no human intervention. In addition, the following rules apply:

• All code must be reentrant. You can expect several copies of your component to run simultaneously.
• All components must use the internal tracing facility. No system out tracing is allowed. Use trace levels such as TREE, DEEP, and DATA properly to avoid over-tracing.
• All components must be self-recovering. The components extend engine classes that perform much of the recovery, but your component should never simply throw an exception or ever call System.exit() for any reason.
• All parameters must be in the run time catalog (dictionary), described by the masterInfo class associated with your component. Specifically, do not create your own properties objects.
• All components must be ISO I18N compliant. The engine provides facilities to assist in this. Never call getBytes() without an encoding.
