Integration Gateway: REST data source, overview of Blogs

This blog post aims to collect all links to Blogs and Documents that provide tutorials and information about the REST 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, and also REST-services.

In order to make use of a REST data source, the OData service developer has to write custom coding.

Which is explained in the following blogs.

Processing the response payload

The main task that has to be implemented in the script is to transform the payload of the REST service into a common data structure.

For better understanding and easier getting up to speed, the following blogs provide a very simple example with hard-coded payload

These blogs are based on the QUERY operation

REST service with xml payload

The same with JSON payload

QUERY operation: The next step: not hard-coded, using string operations

Alternative: using parser to avoid string operations
