SAP Integration with JBoss Technologies Non -confidential 2

Agenda

● Red Hat JBoss Middleware Products ● Introduction to SAP integration technologies

– REST based approach with SAP NetWeaver Gateway

– SOAP based approach with SAP Enterprise Services

– Remote Function Calls with the Java EE Connector Architecture

● Recommendations & Examples

Session title

Red Hat JBoss EAP 6 – Cloud Ready Architecture

● Modular architecture & high degree of automation

● Flexible management● Frugal use of resources● Lean, agile development● Open platform● Java EE 6 standard● Subsystems (Web Technologies, Enterprise

App. Technologies, Web Services Technologies, Management and Security Technologies) are what make up the functionality of the Application Server

Session title

Red Hat JBoss Fuse – Build Your Own Way

● Elastic footprint and flexible architecture● Based on open source Apache projects

– Apache CXF, Apache Camel

– Apache ActiveMQ

– Apache Karaf + Fuse Fabric

● Apache CXF (HTTP, SOAP, REST ) or Apache Camel (SAP NetWeaver Gateway Camel Component) supports the integration with ERP systems

Session title

Red Hat JBoss SOA Platform 6 – More in the Box

● A standard based, service development, deployment and integration platform

● Ease of use● Technology refresh (EAP 6, OASIS ”

SCA, S-RAMP”, Core ESB

“Camel, CXF, ActiveMQ”, Maven)● Governance● Functional equivalence with SOA 5

SOA 6 Platform Architecture

Red Hat JBoss Data Services - Data Virtualization

● JBoss Data Services is a data federation and virtualization engine, that allows you to query multiple data sources (RDBMs, Web Services, Files, Applications, etc.) as though they were a single unified source

Introduction to integration technologies

SAP NetWeaver Gateway

Session title

SAP NetWeaver Gateway: Goals

● No SAP knowledge required● Use of open, non-proprietary technologies● Language independent● Embrace mobile and tablet devices● Data-centric approach

Session title

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

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

Session title

SAP Enterprise Services

Session title

SAP Enterprise Services: Goals

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

Session title

SAP Enterprise Services: Characteristics

● Expose existing ABAP functions as Web Services– HTTP(S)

– SOAP

– XML

● In SAP ERP, a WS wrapper can be created for existing functions

Session title

SAP Enterprise Services: Pros and Cons

● Pros– Work well with SOA platforms

– Familiar tools and technologies for Java devs

– Use WDSL to generate client code

– Trivial to create Web Service wrapper in SAP

– No additional installs / hardware

● Cons– SOAP / WS* hell ;-)

– Not transactional

Session title

Remote

Function

Session title

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

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

Resource Adapters for SAP: Availability

● SAP's own RA only runs on SAP NetWeaver Application Server ;-(● Open Source alternatives:

– Cuckoo Resource Adapter for SAP ● LGPL● http://sourceforge.net/projects/cuckoo-ra/

– JBoss SAP JCA Connector● LGPL● https://github.com/punkhorn/jboss-sap-jca

● All these use the SAP Java Connector (JCo) under the hood

Session title

JCA + JCo: Pros and Cons

● Pros– Fits well into Java EE world

– No additional installs on SAP backend

– Bidirectional communication possible (Java calls SAP, SAP calls Java)

– Transactional

● Cons– Proprietary protocol

– JCA Common Client Interface (CCI): overly generic, lots of glue code

Session title

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)

Session title

Recommendations & Examples

Session title

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

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

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

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

Session title

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
