Apache servicemix1

  1. 1. What is an Apache-Service Mix ? Apache ServiceMix is an enterprise-class open-source distributed enterprise service bus (ESB) and serviceoriented architecture (SOA) toolkit. It was built from the ground up on the semantics and APIs of the Java Business Integration (JBI) specification JSR 208 and released under the Apache License. ServiceMix 4 also fully supports OSGi. ServiceMix is lightweight and easily embeddable, has integrated Spring support and can be run at the edge of the network (inside a client or server), as a standalone ESB provider or as a service within another ESB. You can use ServiceMix in Java SE or a Java EE application server. ServiceMix uses ActiveMQ to provide remoting, clustering, reliability and distributed failover.
  2. 2. What is an ESB ? "An Enterprise Service Bus (ESB) is a new architecture that, exploits Web services, Messaging middleware, intelligent routing, and transformation. ESBs act as a lightweight, ubiquitous integration backbone through which software services and application components flow.”
  3. 3. What is an ESB ?? An ESB acts as a shared messaging layer for connecting applications and other services throughout an enterprise computing infrastructure. It supplements its core asynchronous messaging backbone with intelligent transformation and routing to ensure messages are passed reliably. Services participate in the ESB using either web services messaging standards or JMS
  4. 4. ESB Architecture
  5. 5. Apache ServiceMix - Architecture §ServiceMix employs a layered architecture based on OSGi • The core : A lightweight runtime named “Karaf”, which extends OSGi with powerful features for handling and managing OSGI bundles • The technology layer : A layer of component technologies that sits on top of the core to support your applications
  6. 6. Apache ServiceMix–Core Layer Features •Hot deployment support for OSGi bundles • Dynamic configuration of services through the OSGi “ConfigurationAdmin” service • Dynamic logging back-end provided by Log4J supports different APIs (SLF4J, Java Utils, JCL, Avalon, Tomcat, OSGi) • Application provisioning through file-drop, Maven repository and remote download (http://) • Administration via an extensible shell console • Secure remote access via ssh • Security framework based on JAAS
  7. 7. Apache ServiceMix – Technology Layer Features oSpring Framework • ServiceMix loads an OSGi bundle into its runtime, or generates an OSGi bundle on the fly, and then instantiates the Spring application context o JMS Message Broker • ServiceMix deploys the Apache ActiveMQ broker (OSGi-ready) o JAX-WS/JAX-RS Web Services support • ServiceMix deploys the Apache CXF runtime (OSGi-ready) o Enterprise Integration Patterns (EIP) support • ServiceMix deploys the Apache Camel runtime (OSGi-ready) o Java Business Integration (JBI) support • ServiceMix provides a JBI 1.0 container, to support legacy code • implemented as service units / service assemblies and deployed using ServiceMix 3.x oCan be extended to support technologies such as SCA or EJB3
  8. 8. Apache ServiceMix – Deployment Model oWhen you deploy a ServiceMix solution, you typically deploy the core (Karaf) plus one or more technology Components oExamples: • To support EIPs : Karaf runtime + Camel feature • To support JAX-WS/JAX-RS solutions : Karaf runtime + CXF feature • To support JMS solutions : Karaf runtime + ActiveMQ feature • To support JBI-based solutions : Karaf runtime + JBI feature
  9. 9. JBI (Java Business Integration) JBI defines an architecture that allows the construction of integration systems from plug-in components, that interoperate through the method of mediated message exchange.
  10. 10. JBI 2 kinds of components ● Service Engine (SE) Allow implementing business logic or services on the ESB e.g. servicemix-drools or servicemix-bean ● Binding Components Provide connectivity to external services (transport, normalization, ...) e.g. servicemix-ftp or servicemix-http
  11. 11. Message Routing
  12. 12. Overview of apache servicemix Apache ServiceMix – Integration container Apache Camel – Integration Routes Apache ActiveMQ - Messaging Apache Karaf – OSGI Management Apache Felix - OSGI Apache Aries – OSGI enterprise
  13. 13. Installation System requirements • Java Developer Kit (JDK) 1.6.x (Java 6), for both deployment and compiling. (Note: Java 7 is currently not supported) • About 100 MB of free disk space Downloading Apache ServiceMix • Apache ServiceMix 4.4.2 is available under the Apache License v2 and can be downloaded from http://servicemix.apache.org/downloads.html. Depending on your operation system, you should download either the tar.gz or the zip file: • tar.gz for Linux/Unix/MacOS X • zip for Windows
  14. 14. Installation On Linux/Unix/MacOS X On a command shell, navigate to the directory where you extracted ServiceMix and the bin/servicemix shell script Example: if ServiceMix is installed in the ~/Applications/apache-servicemix4.4.2 directory. $ cd ~/Applications/apache-servicemix-4.4.2 $ ./bin/servicemix !/quickstart/images/start-linux.png |width=75%|height=75%! Apache ServiceMix 4.4.2
  15. 15. Apache ServiceMix console Working with bundles • When ServiceMix is first started, a whole set of bundles providing the core features for the product are being installed. Let's use the command console to find out more about them... • The osgi:list command can be used to get a list of all bundles currently installed. Enter this karaf@root> osgi:list For every bundle, you see: • the bundle id • the bundle state • if the bundle contains a Blueprint or Spring XML file, the next 2 columns will show you if the beans defined there were created successfully • the bundle start level • the bundle name and version
  16. 16. Apache ServiceMix console KARAF – It is a command line tool used to install/uninstall parts of a SMX application and also to troubleshoot problems
  17. 17. Apache ServiceMix console Grep command in karaf karaf@root> osgi:list | grep camel
  18. 18. Apache ServiceMix console Working with logging • To look at the message in the log file - karaf@root> log:display • If you're only interested in the latest exception in the log file - karaf@root> log:display-exception • You can also change the log level at runtime by using the log:set command. You can try these commands on your instance now by first setting the log level to DEBUG and then using grep to make sure that you can actually see the extra logging. - karaf@root> log:set DEBUG - karaf@root> log:display | grep DEBUG
  19. 19. Checking Logs file karaf@root>log:display-exception it display the current exception
  20. 20. Checking Logs file karaf@root>log:set DEBUG to set the logs in DEBUG Mode karaf@root>log:display karaf@root>log:set INFO to set the logs in INFO Mode karaf@root>log:display
  21. 21. Other Optional features: The list of features is available with the features:list command, we are taking some of few regular basis command.This command shows the status weather it is installed or not, and other tab shows version and Name. and grep to find the things in the list that you're interested in. karaf@root> features:list karaf@root> features:list | grep camel
  22. 22. Web console:To get the web console installed in ServiceMix, install the feature from your console karaf@root> features:install webconsole karaf@root> features:list | grep webconsole your browser to http://localhost:8181/system/console and login with user smx and password smx to access the web console
  23. 23. Servicemix-camel : The servicemix-camel component provides support for using Apache Camel to provide a full set of Enterprise Integration Patterns and flexible routing and transformation in both Java code or Spring XML to route services on the Normalized Message Router Camel –Route and Active MQ Deployment : The way to deploy the Camel route Blueprint and Active MQ XML files both having same procedure. 1)Create a new file having the Below configration in the Deployment directory. 2)When the file deployed sucessfully it creates two folder in the home directory (as per specified in Blueprint.XML file) 3)One is HOME/ input and Home/output dir 4)Now copy a file in the input Dir 5)It automatically copied to output Dir For ActiveMQ it create a new dir under HOME is ActiveMQ and under this we have two sub directory Input and Output Let see in our new slide…
  24. 24. Servicemix-camel : Overview Diagram
  25. 25. Camel Route:1) Define the route in a Blueprint XML file in deployment folder having the below configrations. 2) Just create a new XML file in the deploy folder with the code below to start a route to copy files from one directory to another.
  26. 26. Check in Logs by log:display we got the below massage for the file sucessfully moved
  27. 27. To Stop and Starts the Route below are the commands: karaf@root> osgi:stop 200 karaf@root> osgi:start 200
  28. 28. To Stop and Starts the Route below are the commands: karaf@root> osgi:stop 200 karaf@root> osgi:start 200
  29. 29. Adding ActiveMQ to the ServiceMix: Apache ServiceMix instance comes with an embedded ActiveMQ JMS broker. This makes it easy to communicate between Camel routes using persistent messages on the same machine, but it will also enable you to distribute your routes over multiple instances afterwards for clustering or load-balancing.
  30. 30. Save this file in ServiceMix' deploy folder and use osgi:list to check on the bundle status You should now be able to put files in the activemq/input directory and see them being moved to activemq/output. Receiving the event messages: After deploying the first XML file, you're obviously not seeing any events being logged yet. The event messages are sent to an ActiveMQ queue, but there's nobody to receive the events yet. Let's change that now by creating a second Blueprint XML file.
  31. 31. Checking Logs file: As soon as this second file has been deployed, you'll start seeing the event messages in your log:display output
