Overview

The sap2java open source project provides a developer-friendly API for working with the Open Enterprise Foundation's SAP Java Connector.  The project also includes a useful tool for the automatic generation of Java data object classes from an SAP remote-enabled function (RFC) interface.  The iJAG group has modified the sap2java source code to expand its functionality to include handling of more complex RFC interfaces than the original project allowed.  The source code requires occasional enhancement as additional SAP data types not currently accommodated are used by SAP RFC developers.

Generate Java Data Object Classes from an SAP Remote-enabled Function Interface

1. Check out or update the sap2java Eclipse project.  If needed, refer to the iJAG FAQ for instructions on checking out an Eclipse project.
2. In the sap2java project, open package src/com/sap/bapi/mapper. Right-click on class, testSAP2Java, and select "Run As..." from the context menu.
3. Create a new Java Application run profile for testSAP2Java or open its previously created profile, then select the "Arguments" tab.
4. In the "Program arguments" text area, add the following lines:

   "${workspace_loc}/<myProject>/src"
   edu.mit.<myProject>.proxy
   <rfcName>
   

   where <myProject> is the name of the target Eclipse project and <rfcName> is the name of the RFC for which you are generating Java data object classes.

1. Add 3 params in the box:

• The directory in your project where proxies need to go, e.g.
  Unknown macro: {workspace-dir}
  /vpis/src
• The package name of the generated proxies, e.g. edu.mit.vpis.proxy
• The name of the rfc

1. Click run

This will generate proxies in your actual app directory, which you may need to refresh (to see them).
