Modern Java Web Development
- 1. Modern Java Web DevelopmentBy Zenyk Matchyshyn
- 2. AgendaWeb frameworks classificationMajor frameworks in each classHow to select a framework and typical combinationsRapid web development on JavaModern approaches to development2
- 3. Web Frameworks ClassificationWeb Frameworks can be classified into following categories:Request/Action Frameworks (Spring MVC, Struts 2, …)Component Frameworks (GWT, JSF, …)Server Side Frameworks (BlazeDS, Jax-RS, …)3
- 4. Request/Action FrameworksFollows classic MVC patternNo notion of componentReusability of controllers and viewsHave similar structure and conceptsSimple and straightforwardBetter suited for simple sites Examples: Spring MVC, Struts 2Non Java examples: Ruby on Rails, ASP.NET MVC4
- 5. Component FrameworksHave components at its coreBetter suited for RIA applications and Forms applicationsMore complex Examples: GWT, JSF, Tapestry 5Non Java examples: ASP.NET5
- 6. Server Side FrameworksDivided into following groups:Web Services (SOAP and RESTful)Flex Server SideAjax libraries, Serialization/Marshaling libraries6
- 7. Web ServicesSOAP basedFrameworks: Axis 1/2, Spring WS, JAX-WS XML basedRESTful (Jax-RS, Spring MVC, …):Frameworks: Follows REST guidelinesXML, JSON or other protocol7
- 8. FlexMain frameworks: BlazeDS, WebORB, Granite DS, LiveCycle Data ServicesProvide serialization for AMF protocolSome have code generationJava is first class citizen in Flex worldMain features: remoting, proxy service, pub/sub over HTTP and JMS 8
- 9. Ajax Libraries and custom serializationDirect Web Remoting (DWR)Custom serializators based on popular protocol (JSON, XML, YAML, …)Usually build on top of Servlet API or Action frameworks such as Spring MVC9
- 11. Google Web ToolkitCurrent version – 2.2Evolves, supported by GoogleHave forks: GWT-Ext, Vaadin, SmartGWTGood tooling: Google Plugin for Eclipse, visual designerNot just for RIA (Odnoklasniki!)Heavy Java orientationDebug and deployment sometimes complicated11
- 12. Spring MVCCurrent version – 3.1Led by SpringSource – doesn’t evolveLots of view resolversTooling is supported on a Spring Framework levelLots of documentation, implementations and examples12
- 13. Java Server FacesCurrent version – 2.0Led by JCP (Oracle)Evolves, supported by big companiesPainful, but standardLibraries - Apache MyFaces, JbossRichFaces, Oracle ADFTooling is limitedSignificant version differences13
- 14. Struts 2 and StripesAction/Request based frameworksActively developedStruts 2 – Apache project, latest release – 20 Dec 2010Struts 2 = Struts 1 + WebWorkStruts 2 uses OGNLStripes – latest release – 4 Jan 2011Some success storiesBooks, tutorials available14
- 15. Tapestry 5 and WicketTapestry 5 and Wicket are Apache projectsBoth are component basedTapestry 5 latest release 15 Nov 2010Wicket latest release – 21 Jan 2011Tapestry uses OGNLWicket is more Java oriented15

- 19. ComparisonHigh traffic, internet facing, infinite scalability – Action/Request based frameworkIntranet based, few users, behind firewall – Component based frameworkProducts, to be maintained for 5-10 years – largest community, most vendor supportLegacy backend – same language as backendDone by Matt Raible - http://bit.ly/jvm-frameworks-matrixYou should have yours!19
- 20. Typical frameworks combinationsConsider JavaScript librariesYUI/Ext JS/Dojo/jQuery + Action/Request based – gives separation of front end and server sideGWT + Spring MVC – gives components and flexibility where necessaryJSF + JAX-RS – gives components and REST access for JavaScript UI20
- 22. Spring RooGenerates typical combinations between database, models, controllers and viewsSupports Hibernate, GWT, Spring MVC, Spring Security, Maven, JPA and tons more…Waving can be turned off (remove Spring Roo)Actively developedhttp://www.springsource.org/roo22
- 23. AppFuseGenerates basic project using typical combinationsGood place to learn best practicesCan generate code based on DB schemaSomewhat evolvinghttp://appfuse.org23
- 24. Custom FactoriesUse Maven!Use scripting!Use code generators – Skyway Builder, SpringFuseMost companies are doing it rightReuse experience24
- 25. Modern Approaches to development25
- 26. ToolsUse Eclipse/Idea/NetBeansMaven works, just use the latest version and Maven Shellm2eclipse, jetty plugin or tomcat pluginUse JRebel for zero turnaround Tomcat and Jetty – rocks!26
- 27. ArchitectureUse JavaScript frameworksUse IoC frameworks (Spring, Guice, …) but keep classpath cleanKeep session isolatedAvoid JSPMinimize Controllers layerUse existing security solutions e.g. Spring SecurityEach module should have its own Maven artifact27
- 28. Friends from neighborhood JRuby on Rails great for prototypingJRubydeveloped by OracleGroovy on Grails great for new small and medium projectsGroovy developed by SpringSourcePossible to use existing business login on other languagesLearn and apply best practices from non Java frameworks28
- 29. Future – Java EE 6 Web ProfileServlet 3.0: Web Fragments, Async API, programmatic methods to add servlets and filters, Annotations, Security enhancements JSP 2.2 / EL 2.2 : method invocations, new properties Web BeansBean ValidationManaged Beans29
