5 CQ in an Enterprise Environment

6 CQ in an Enterprise Environment CQ can be used standalone as a WCMS But: Usually a company has more systems then just the WCMS to store, process and retrieve data from A company might want to display and let the user enter data from these other systems through their CQ-powered website Integrating these other systems in real-time opens up great new business opportunities Unic - Seite 6

9 Integration Layer

10 Integration Layer Most use cases require not just one backend system, but the ordered access to several of them all of which might greatly differ from each other Business Rules and Processes Service Orchestration Heterogeneous Technologies Transactions Different Data Structures and Protocols Unic - Seite 10

11 Integration Layer Product Management JMS / Binary User Management REST / JSON CQ (User Access ) Car Connect HTTP / SOAP JMS / XML CRM FTP / Binary Software Distribution SMTP / SOAP Other s Unic - Seite 11

12 Integration Layer Product Management JMS / Binary JMS / XML CRM User Management? REST / JSON CQ? (User Access )? FTP / Binary Software Distribution Car Connect HTTP / SOAP SMTP / SOAP Other s Unic - Seite 12

15 Integration Layer Advantages of using an ESB like Apache ServiceMix Separation of Concerns Leveraging the individual strengths of each system Easy reuse of middleware for different frontends Increased organizational flexibility Increased specialization of development teams Opportunity to scale integration layer and CQ independently More reliable system, by using technologies specially tailored for integration Increased cost efficiency and lower TCO Unic - Seite 15

16 Connecting to the ESB

17 Connecting to the ESB The communication between CQ and Apache ServiceMix is RESTful Based on the HTTP protocol Exchange of JSON request and response objects As the client library we chose the OSGI version of the Apache HTTP components library For ease of use we built a light-weight RelayService framework on top of it Unic - Seite 17

18 Connecting to the ESB CQ Service Controller CustomRelayService Automatic adding of common headers Automatic JSON handling JsonRelayService HttpClient Abstraction DefaultRelayService Apache HttpClient Apache ServiceMix Unic - Seite 18

19 Connecting to the ESB To support the full live cycle of resources, we use all of these HTTP methods GET To get lists of resources and single resources doget( ) POST To create a new resource dopost( ) PUT To update a resource doput( ) DELETE To delete a resource dodelete( ) Unic - Seite 19

20 Connecting to the ESB Resource: Custom lists of Points of Interest Retrieve lists: relayservice.doget( ); Upload a new list: relayservice.dopost( listjson); Update a list: relayservice.doput( updatedjson); Delete a list: relayservice.dodelete( ); Unic - Seite 20

21 Connecting to the ESB Data Exchange Format: JSON Lightweight, Easy to use especially within Javascript frontend Conversion to and from Java objects is done with Google Gson For dependency injection Gson is wrapped in a Spring component All changes, validation, localization etc. are done on Java objects Unic - Seite 21

22 Modes of Content Retrieval

23 Modes of Content Retrieval Synchroneous Mode CQ Browser Component JSP Resource Model Service Relay Service ESB Unic - Seite 23

24 Modes of Content Retrieval Asynchroneous Mode CQ Browser Component JSP Resource Model Spring MVC Controller Relay Service ESB AJAX Unic - Seite 24

25 Modes of Content Retrieval Based on Unic proprietary library NEBA II Allows mapping of CRX content to Java objects (Resource Models) Integrates Spring framework into CQ Dependency Injection Spring MVC with Spring DispatcherServlet as Sling registered servlet Unic - Seite 25

26 Conclusion

27 Conclusion Todays enterprises have numerous systems holding and processing data Business processes require the interaction with several of these systems CQ can act as the user facing system and a channel to the backend systems An ESB like Apache ServiceMix can be used to integrate the various backend systems in real-time Lots of technical, organizational, financial and business advantages can be achieved Unic - Seite 27
