JazzTeam.org Springsite.com Eclipse Foundation6/43 Как появился заказчик Всегда вкладывай в людей, с которыми работаешь –Получена рекомендация У думающих людей не бывает плохого опыта –Экспертиза fits requirements (Epam CMS) Мой вопрос к Аркадию Добкину и его ответ про продуктовые и аутсорсинговые компании Мысль материальна –Заказчик из мира Open Source

JazzTeam.org Springsite.com Eclipse Foundation7/43 Задачи Integrate enterprise CMS Contact management Complicated search among all the products (including competitors) E-news, subscribers management Products management (batch update too) Web statistics Support all possible roles, flows (editor, admin, technical admin) All should be friendly-administrated

JazzTeam.org Springsite.com Eclipse Foundation12/43 Why not to use Mind Maps for project documentation

JazzTeam.org Springsite.com Eclipse Foundation13/43 Open for architecture changes Feel free to customize if need (coding) –Seam –Alfresco –Chiba (OS W3C XForms implementation) –Hibernate –Eclipse Texo New phase of development (project Teneo)

JazzTeam.org Springsite.com Eclipse Foundation14/43 No fear, motivated to new We need apply recursion into XForms and implement/built in recursive AJAX UI – let us invest time/money into it and gain knowledge on this area deeper –Конечно, позволял заказчик –2 человека-месяца (с высокой квалификацией) Alfresco server debug Complicated UI (hundreds of recursive controls, which are widgets itself)

JazzTeam.org Springsite.com Eclipse Foundation15/43 Recursive XSD widgets (xs:switch) AJAX based

JazzTeam.org Springsite.com Eclipse Foundation20/43 Alfresco notes State of art. Wanna grow in Java – study sources of Alfresco or Seam Modularity All is node and services around –Not only document management –Everything related to node could be implemented Node type Flows, Web Forms and many other things –extendable XSD + XSLT (other templating language) = XML, HTML, JS, Java, JSF – anything Web scripting The same model as Epam CMS It is possible to have XSD describing layout Крым, Симферополь, Детский джазовый концерт

JazzTeam.org Springsite.com Eclipse Foundation32/43 Project data exchange

JazzTeam.org Springsite.com Eclipse Foundation33/43 Open Source contribution results Eclipse Teneo (only ORM) > Texo –One more Eclipse member Chiba changes contribution Tries to discuss XForms standard changes Seam forum participating –Issue with contexts Alfresco changes –Dramatic WCM AJAX, layout to manage renditions, others –A wish to become commercial committer –Contribution is sent but particularly ignored

JazzTeam.org Springsite.com Eclipse Foundation34/43 Типы кастомизаций IoC, reflexion через файлы настроек Скачать сырцы, что-то изменить, переподложить под сервер Сырцов нету (multivalent.sourceforge.net). Decompile, adjust, compile Два последних варинта рискованны, если продукт будет долго развиваться.

JazzTeam.org Springsite.com Eclipse Foundation35/43 Open Source model of project vertical model - OOP > reusable components > frameworks > open source > usage at next projects Motivation Convenient way to touch with partners –Ask them to join your OS project and see what happens All that is done for free in minutes, and results in a week (productivity etc)

JazzTeam.org Springsite.com Eclipse Foundation36/43 Open Source cons (то, что всплыло на проекте) Weak communities Not always user centric development Смешение технологий – for handy people Нет успокоения (но и нет старпёрства) Customizations, customizations, customizations Effort on R&D Из интерьера знаменитой 49 квартиры

JazzTeam.org Springsite.com Eclipse Foundation37/43 Money? Become committer with potential customer Long investments Create popular industry/direction (что сейчас делается в проекте Texo) Конференции, где бывают заказчики мира Java Open Source Independent consulting Name A way to start cooperation with people immediately –For eclipse – not one month of contribution –For sourceforge etc. Create user Add to project Develop Use Case Способный customer facer Могу дать телефон

JazzTeam.org Springsite.com Eclipse Foundation38/43 CMS Good to have XSD support –And recursion Good to become an entry point for all the management/admin pages Good to be node specific Good to have web scripting finally flows And convenient management of renditions E-CMS integration should allow to do (web.xml, configs, bundles, localization) in the way you use wordpress

JazzTeam.org Springsite.com Eclipse Foundation39/43 Bonus 00: j2ee vs ruby (basing on mashpit trainings) Context handling Много времени для вхождения новичкам Хостинг дешевеет, clouding Java is up to have closures Byte code manipulators Aop, IoC, OSGI Simple syntax Proved technology MVC frameworks: spring, struts, seam. Tons of views, TDD ORM and JPA Ant, Maven Good to have compilation errors Стенсил во Львове

JazzTeam.org Springsite.com Eclipse Foundation40/43 Bonus 01: расширяемое программирование in Java Пляшем от полиморфизма Generics IoC(spring, self-made, seam, web.xml, context.xml) Dependency injection (interceptors, chains), AoP (joints) Patterns Plugins (self made, OSGI, etc.) WS-* (service mix, equinox, wsdl, JSON, REST) Bytes manipulation (create classes on the flight, interception on the flight – hard to debug) Polymorphic systems (ruby frontend – java backend) Class loading art UI: widgets, web scripting MDD, TDD, CMS took important role Built in scripting
