Service Mash-up in Integration Gateway – It’s Simpler Than You Think

Integration gateway is a component in SAP Mobile Platform 3, it converts different types of protocols to Odata protocol. Currently it supports SOAP, JDBC, JPA, ODC and REST (read and query). This example is on how to mashup multiple backends and create an Odata service using Integration Gateway.

  • SAP Mobile Platform 3.0 SP05 Developer Installation
  • Eclipse Kepler
  • SAP Mobile Platform Eclipse Plugins. Available from the SAP eclipse update site:
  • HSQLDB (jdbc)

Steps to Create Project

  • Open Eclipse and select File > New > SAP Mobile Platform Odata Implementation Project.
  • In the pop up window provide the project name “ServiceMashup”.
  • Select Target Runtime Server as “SAP Mobile Platform 3.0 SP5”. Click Next.
  • Enter Model name as “model”. Then click on Finish. It creates the ServiceMashup project in the workspace.

  • Create entity types CustomerObj and Article, and a complex Type Price.

Note that datatype of ID in CustomerObj is integer (edm.Int16) and BIRTHDATE is Datetime (edm.datetime).

I have followed the existing examples Integration Gateway with JDBC and Integration Gateway with SOAP as a source for this blog. So in this blog I am not explaining how to set up HSQLDB. Copy and paste JDBC driver package (hsqldb.jar file) from ..\hsqldb-2.3.2\hsqldb\lib to C:\SAP\MobilePlatform3\Server\pickup .


Define Data Source

  • From the Project Explorer right click on model.odatasrv file > Select Data Source.
  • Choose Entity Set “model.default.CustomerObjSet”
  • Select Query from Operations and select JDBC as Data source. Click Finish.

  • Right click on model.odatasrv file > Select Data Source.
  • Choose Entity Set “model.default.ArticleSet”
  • Select Query from Operations and select SOAP Service as Data source.

      Hi Midhun,

      I want to create a mashup service for Gateway Services using ODC as Data source.

      So when I create a new SAP Implmentation Project in Eclipse I choose "OData Service URL" as Odata Model and then I specify the service url in next screen. An entity set for all the collections in that service is created in Eclipse.

      But I also want to use different Service URLs in the same Mashup. So I add a new Odata Model selcting "OData Service URL" and that model is created. But for this new model there is not Model.odatasrv file created which has option to "Select Data Source".

      This file exists only for the model that was added at project creation and not for the models added later.

      What can be done in this case?
