The EntireX documentation contains the following Natural-related topics:

Connecting Natural

Common integration scenarios: Calling your Natural server subprograms from the Integration Server Adapter Service or a web service client; calling an Integration Server Service or a web service from a Natural application.  More info

Natural Wrapper

The Natural Wrapper allows you to develop Natural client applications that access RPC-based server components, and to create Natural RPC server skeletons you can use as a basis to write a Natural RPC server that can be accessed by RPC clients.  More info

IDL Extractor for Natural

The Software AG IDL Extractor for Natural extracts a Software AG IDL definition from a Natural source in a Natural project in Eclipse, or from an object within a Natural RPC environment.  More info

Java Wrapper for Natural

The EntireX Java Wrapper for Natural allows you to generate EntireX Java client interface objects from Natural subprograms in a NaturalONE project in Eclipse. The generated Java client interface objects can be used by Java application developers to access Natural server components, using EntireX/Natural RPC.  More info

Web Services Wrapper for Natural

The EntireX Web Services Wrapper for Natural allows you to develop Web Services that access Natural server components, using EntireX/Natural RPC.  More info

Broker ACI for Natural
