etc.) as though they were a single
unified source

13. SAP NetWeaver Gateway: Characteristics
●
A set of add-ons to existing SAP ABAP stack
●
Embraces REST architectural style
–
–
●
HTTP(S)
XML or JSON data formats
Tools for Eclipse, Visual Studio and Xcode
–
Find exposed services and generate code
Session title

14. SAP NetWeaver Gateway: Pros and Cons
●
Pros
–
–
●
Familiar tools and technologies for Java devs
Existing ABAP functions/dialogs can easily be exposed as a Gateway service
Cons
–
NetWeaver Gateway needs to be installed in SAP backend or separately
–
Creating services in ABAP not trivial for more complex scenarios
–
Not transactional

●
No SAP knowledge required
●
Use of open, non-proprietary technologies
●
Language independent
●
Process-centric approach
Session title

17. SAP Enterprise Services: Characteristics
●
Expose existing ABAP functions as Web Services
–
–
SOAP
–
●
HTTP(S)
XML
In SAP ERP, a WS wrapper can be created for existing functions

18. SAP Enterprise Services: Pros and Cons
●
Pros
–
–
Familiar tools and technologies for Java devs
–
Use WDSL to generate client code
–
Trivial to create Web Service wrapper in SAP
–
●
Work well with SOA platforms
No additional installs / hardware
Cons
–
SOAP / WS* hell ;-)
–
Not transactional

19. Introduction to integration technologies
Remote
Function
Calls
Session title
Confidential / NDA Required

20. SAP Remote Function Call (RFC)
●
Call ABAP functions in SAP ERP
●
SAP Java Connector (JCo)
–
Java library
–
Uses the binary SAP RFC protocol, supports
●
Connection pooling
●
Transactions
●
Security
●
Process-centric approach
●
Does not fit very well into Java EE...
Session title

21. Java EE Connector Architecture (JCA)
●
Interaction of Java EE apps with Enterprise Information Systems (EIS)
–
●
… such as SAP ERP
A Resource Adapter
–
is deployed in a Java EE application server
–
implements the JCA for a specific EIS
●
Defines inbound and outbound connectivity
●
Takes care of connections, security, transactions, configuration
Session title

22. Resource Adapters for SAP: Availability
●
SAP's own RA only runs on SAP NetWeaver Application Server ;-(
●
Open Source alternatives:
–
Cuckoo Resource Adapter for SAP
●
●
–
Status: Stable (LGPL)
http://sourceforge.net/projects/cuckoo-ra/
JBoss SAP JCA Connector
●
●
●
Status: In Development (LGPL)
https://github.com/punkhorn/jboss-sap-jca
All these use the SAP Java Connector (JCo) under the hood
Session title

23. JCA + JCo: Pros and Cons
●
Pros
–
–
No additional installs on SAP backend
–
Bidirectional communication possible (Java calls SAP, SAP calls Java)
–
●
Fits well into Java EE world
Transactional
Cons
–
Proprietary protocol
–
JCA Common Client Interface (CCI): overly generic, lots of glue code
Session title

24. Hibersap
●
“O/R-Mapper for SAP”
●
Mapping of ABAP functions to Java objects
–
with Java annotations
●
Lean API
●
On top of JCA Resource Adapter or JCo
●
Open Source (LGPL)

25. Where to go?
Session title
Confidential / NDA Required

26. The data-centric approach
●
When you expose data from an SAP ERP system to your application
–
●
Use SAP NetWeaver Gateway
The JBoss Data Services Platform with NetWeaver Gateway gives you
–
… a common way to unify virtualized view of information combined from
multiple disparate sources (SAPs, …)
–
… the ability to enable users and applications to query and manage the
integrated data as if it were located in a single database via a single uniform
API
Session title

27. The data-centric approach: Example 1
●
●
●
Web app for S&D for use by mobile
and desktop devices
Search, view, change and create
customers and related data
Customer data resides in SAP ERP
Session title
SAP Integration with JBoss Technologies
Non -confidential
27

28. The data-centric approach: Example 2
●
●
●
Reporting App for an online credit
platform
Aggregate and virtualize credit
request customer's data
Customer's data resides in different
sources (DB, SAP, Salesforce)
Session title

29. The process-centric approach
●
●
When integrating business processes into your Java EE app, consider
using Hibersap with JCA
This makes sure
–
... your data stays consistent in all systems
–
… you are ready for complex scenarios
–
… your code remains expressive and maintainable

30. The process-centric approach: Example
●
Hospital Information System
●
Java EE application w/ Rich Client
●
●
●
Invoices are created in Java EE
application
Further financial processes take
place in SAP ERP
Distributed transactions guarantee
data consistency in both systems
