Using custom payload converters

If a custom payload converter is required for an application that is neither included in the framework nor the application itself, such converters can be implemented separately using the Gateway Framework and then utilized.

For information on how to write a payload converter, please refer to how to write a payload converter.

Once the converter is implemented, a JAR file containing this converter can be supplied in the classpath of the application during startup. Alternatively, the JAR file can be placed in a directory, and the path of the directory can be set as the value for the gateway.ext.dir system property. The framework will load this directory into the classpath during application startup. The application configuration can then be updated to include a service that uses this converter. Once the service is added, this custom converter will be instantiated and used for the service.
