  12. ESB Definition • There is NO J2EE-like specification with a TCK that can define and validate an ESB like there is for App Servers. • ESBs are categorized by their capabilities – some come from a heritage of EAI and others of MOM. • Capabilities: • Message delivery • Transport protocol mediation • Event capture • Intelligent routing • Orchestration • Transformation • BPM • Adapters • And much, much more…

  13. JBossESB 4.2 provides • Message delivery • JMS (JBossMQ, JBoss Messaging, ActiveMQ, MQSeries, Oracle AQ, TIBCO EMS) • FTP, SOAP, email, database, shared file system • Action chaining/pipeline • For custom service enablement & mediation • Transformation • XSLT, Java, Groovy, StringTemplate, Freemarker • Content-based routing • JBoss Rules, XPath DSL • Recipient List/Static Routing is also supported • Orchestration • BPM, Intelligent routing, EIPs and hot deployment • Registry • JAX-R based • UDDI support out-of-the-box • Message Store • Gateways • Extensive examples and documentation • And more…

  14. JBoss ESB 4.2 • Content Based Filter • Business Rules Services • Native Process Orchestration • Hibernate Gateway/Listener • HTTP Gateway/Listener • Groovy Scripting • Declarative Message Store • JCA Container • Spring Action AOP & POJO • Monitoring & Mgmt Tools • Additional EIP examples • JMX Microkernel • Federated Clustering • WS-* • SOAP • WSDL • JAX-WS Annotated POJO Endpoints • EJB Endpoints • JAXB 2.0 • BPEL 2.0 • New Deployment Architecture • .esb Archive • Hot Deployable Core Services

  15. Action Action Action Action Action Action Pipeline (in a Service) Actions are reusable mediation components that can be chained together to form the capabilities of a registered service. Actions can be dynamically added/removed at runtime. My_Registered_Service Business Logic Component FTP • Business Logic: • POJO • EJB • WS • Rules • JCA with Adapters • Anything with Java API Transformation CSV to XML RoutingSplitter or BPM Logging Audit Trail Business Logic Invocation Transformation XML to POJO This box can also represent the ESB’s JVM – actions are “in VM”

  16. Out of the Box Actions • MessagePersister • Notifier • ObjectToCSVString • ObjectToXStream • SmooksTransformer • SOAPProcessor • SOAPClient • StaticRouter • StaticWiretap • SystemPrintln • XStreamToObject • AbstractSpringAction • Aggregator • BeanConfiguredAction • BpmProcessor • BusinessRulesProcessor • ByteArrayToString • ContentBasedRouter • ContentBasedWiretap • GroovyActionProcessor • HttpRouter • JMSRouter • LongToDateConverter • MessageFilter Refer to the MessageActionGuide.pdf

  17. Basic Service Demo

  18. ASCIIXML Binary Action Action Action Content Based Routing Orders over 12K or from Platinum customers Platinum_Service SOAP Ordering_Service DB POJO FTP Special_Handling EJB SOAP DB Randomly grab orders for review – tracer and Keep a total of all orders flowing through the system Orders from customers in certain states/countries

  19. Content Based Routing Engine • Currently based on JBoss Rules – supports XPATH DSL • Access to the complete Header and Body/Contents for evaluation • Zero to many destinations rule "Routing Rule using XPATH Greater" when xpathGreaterThan"/Order/@totalAmount", "50.0" then Log : "Really It's EXPRESS Shipping"; Destination : “express"; end rule "Routing Rule using XPATH Less" when xpathLessThan"/Order/@totalAmount", "50.0" then Log : "Really It's NORMAL Shipping"; Destination : “normal"; end Destination is determined by the jboss-esb.xml

  20. Load Balancing & Fail-Over The same discount_service.esb can be deployed to multiple ESB instances/nodes. Each one is a new EPRs in the registry. The routing engine is clever enough to load-balance and fail-over between the various EPRs. Should no EPR be available, it will scheduled the message for redelivery, waiting N seconds and retrying all possible EPRs found at that time.

  21. Load-Balancing Demo

  22. Deployment Options • 1) ESB “within” an Application Server – Users have existing investments in the J2EE/Java EE App Servers and wish to run the ESB as a set of components in that App Server. • JBoss ESB can run “within” the JBoss Enterprise Application Platform 4.2 • 2) ESB “beside” an Application Server – Users wish to leave their existing application server environments untouched but still add mediation, SOA & integration capabilities. • JBoss ESB has its own lightweight engine/container for the hosting mediation services. It can run “beside” your existing middleware from your vendor of choice. • 3) ESB “standalone” in a J2SE environment – this option is primarily for development & testing purposes

  23. Management & Monitoring • 4.2 Release is focused on JMX instrumentation, the ability to monitor the health and load of every distributed service as well as start, stop & restart them remotely.

A single ESB Service may or may not expose a WSDL. It may use out-of-the-box actions, custom actions and/or consume external services from various sources. Focus on the reuse of existing infrastructure and assets.
