  1. 1. SAP Integration with JBoss Technologies Serge Pagop Sr. Channels Solution Architect spagop@redhat.com 2013-10-02 Carsten Erker Software Architect carsten.erker@akquinet.de
  2. 2. Session title 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
  3. 3. Session title SAP Integration with JBoss Technologies Non -confidential 3 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
  4. 4. Session title SAP Integration with JBoss Technologies Non -confidential 4 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
  5. 5.

  6. 6. Session title SAP Integration with JBoss Technologies Non -confidential 6 SOA 6 Gateways – Connectivity with external systems Camel FTP File JCA JMS JPA Mail Scheduling SQL SCA Netty TCP Netty UDP HTTP REST SOAP SOA 6 Platform Architecture ...
  7. 7. Session title SAP Integration with JBoss Technologies Non -confidential 7 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 EDS v5
  8. 8. Session title SAP Integration with JBoss Technologies Non -confidential 8 How do Red Hat JBoss Data Services Work?
  9. 9. Session title SAP Integration with JBoss Technologies Non -confidential 9 Supported Data Sources Enterprise RDBMS: Oracle IBM DB2 Microsoft SQL Server Sybase ASE MySQL PostgreSQL Ingres Enterprise EDW: Teradata Netezza Greenplum Specialty Data Sources: S-RAMP/ModeShape Repository Mondrian MetaMatrix LDAP Enterprise & Cloud Applications: Salesforce.com SAP Big Data: Apache Hive NoSQL: JBoss Data Grid (Infinispan) MongoDB Technology Connectors: Flat Files, XML Files, XML over HTTP SOAP Web Services REST Web Services OData Services Office Productivity: Microsoft Excel Microsoft Access Google Spreadsheets

  11. 11. Session title Confidential / NDA Required 11 Introduction to integration technologies SAP NetWeaver Gateway
  12. 12. Session title SAP Integration with JBoss Technologies Non -confidential 12 SAP NetWeaver Gateway: Goals ● No SAP knowledge required ● Use of open, non-proprietary technologies ● Language independent ● Embrace mobile and tablet devices ● Data-centric approach
  13. 13. Session title SAP Integration with JBoss Technologies Non -confidential 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
  14. 14. Session title SAP Integration with JBoss Technologies Non -confidential 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
  15. 15. Session title Confidential / NDA Required 15 Introduction to integration technologies SAP Enterprise Services
  16. 16. Session title SAP Integration with JBoss Technologies Non -confidential 16 SAP Enterprise Services: Goals ● No SAP knowledge required ● Use of open, non-proprietary technologies ● Language independent ● Process-centric approach
  17. 17. Session title SAP Integration with JBoss Technologies Non -confidential 17 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
  18. 18. Session title SAP Integration with JBoss Technologies Non -confidential 18 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
  19. 19. Session title Confidential / NDA Required 19 Introduction to integration technologies Remote Function Calls
  20. 20. Session title SAP Integration with JBoss Technologies Non -confidential 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...
  21. 21. Session title SAP Integration with JBoss Technologies Non -confidential 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
  22. 22. Session title SAP Integration with JBoss Technologies Non -confidential 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 ● 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
  23. 23. Session title SAP Integration with JBoss Technologies Non -confidential 23 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
  24. 24. Session title SAP Integration with JBoss Technologies Non -confidential 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. 25. Session title Confidential / NDA Required 25 Recommendations & Examples
  26. 26. Session title SAP Integration with JBoss Technologies Non -confidential 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
  27. 27. Session title SAP Integration with JBoss Technologies Non -confidential 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
  28. 28. Session title SAP Integration with JBoss Technologies Non -confidential 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)
  29. 29. Session title SAP Integration with JBoss Technologies Non -confidential 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. 30. Session title SAP Integration with JBoss Technologies Non -confidential 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
