hibersap-generator

Simple tool generating ready-to-use Hibersap-annotated Java classes by reading SAP ERP ECC/S4 Function Module

What is Hibersap

Hibersap helps developers of Java applications to call business logic in SAP backends. It defines a set of Java annotations to map SAP function modules to Java classes as well as a small, clean API to execute these function modules and handle transaction and security aspects.

Hibersap's programming model is quite similar to those of modern O/R mappers, significantly speeding up the development of SAP interfaces and making it much more fun to write the integration code.

Requirements

• direct access to target SAP ERP ECC/S4 instance (by VPN or LAN)
• SAP JCO3 libraries: download and extract to libs/sapjco3 so that you have libs/sapjco3/sapjco3.jar

SAP ECC/S4 connection

Create a file with SAP ERP ECC/S4 destination settings like ECQ.jcoDestination

 jco.client.ashost=HOST
 jco.client.sysnr=00
 jco.client.client=100
 jco.client.user=USERNAME
 jco.client.passwd=PASSWORD
 jco.client.lang=en

How to use

As an example to generate Hibersap Java classes for SAP function module ZFUNCTION1 from destination ECQ saved in ECQ.jcoDestination file:

Mac/Linux

./gradlew run --args="-sapDestination ECQ -sapFunctionModule ZFUNCTION1"    

Windows

gradle.bat run --args="-sapDestination ECQ -sapFunctionModule ZFUNCTION1"    

Inside folder generated-sources you'll get the generated Java classes.
