This blog post aims to collect all links to Blogs and Documents that provide tutorials and information about the Custom Code data source for Integration Gateway in SAP Mobile Platform 3.0 (SMP).

Based on the component Integration Gateway in SMP, you can provide OData services, that expose data that is fetched from different data sources – like Database, JPA, REST-services, etc

The Custom Code option gives the developer more freedom to provide data by manually implementing the necessary code.

The following tutorials show how to do that and give practical examples.

Introduction

* READ operation, very simplified

* Example for calling an OSGi bundle to provide data

This tutorial uses the Custom Code data source to call Java API that is located on an OSGi bundle that is running on the SMP server.

The tutorial is split in 4 parts, the second part covers the creation of the OData service based on the custom code data source
