The NetWeaver server platform is a subclass of the ServerPlatform class that can be used by customers using SAP NetWeaver Application Server Java:


Starting with release 2.1 it is contained in the standard EclipseLink repository.

Supported Versions

The NetWeaver server platform allows using EclipseLink within SAP NetWeaver Application Server Java. The following versions are supported:

  • SAP NetWeaver 7.1 including EHP 1
  • SAP NetWeaver 7.2
  • SAP NetWeaver 7.3 (not yet publicly available)

Using the NetWeaver Platform

The recommended deployment option is to create a separate deployable application (i.e. an SDA file) containing both eclipselink.jar and netweaver_platform.jar and to reference that application from your Java EE application. See the NetWeaver Help Portal for a description how to do this using SAP NetWeaver Developer Studio.

In order to use EclipseLink in your application, the persistence.xml file must contain the following entries:

  • Add a <provider> tag to each of the defined persistence units (must be the first line after the <persistence-unit> tag) so that EclipseLink will be used as the JPA provider for the respective persistence unit:
  • Include the following property at the end of each persistence unit so that EclipseLink will make use of the NetWeaver platform:
  <property name="" value="org.eclipse.persistence.extensions.platform.server.SAPNetWeaver_7_1_Platform"/>   


  • SAP NetWeaver AS Java (version 7.1 to 7.3) is a Java EE 5 server, hence supporting only JPA 1.0.
  • Dynamic weaving cannot be used inside SAP NetWeaver AS Java. Applications should use static weaving instead.
