  1. AppFuse Architecture Directory Structure, Build/Test/Deploy Processes

  2. Project Structure • Directory structure • Simpler is better • Map to artifacts • Customizations/personalization's • IDE issues • Separate source from artifacts - cleanable

  3. Top-level Directory Structure • bin – automation scripts • lib – 3rd party libraries (i.e. Struts and Hibernate) • metadata – SQL scripts, server configurations and XDoclet fragments • src – Java source files • test – JUnit, Cactus, StrutsTestCase tests • tools – Strutsgen: a tool for generating JSPs from ActionForms • web – JSPs, properties files, images, scripts, stylesheets

  4. Open Source Dependencies • Ant-contrib– use “propertycopy” task in build process • Checkstyle – used to verify that coding standards are followed • Dbunit– cleans/loads data into database before tests are run • Display Tag– used to display list screens (including sorting/paging) • Hibernate– persistence engine • Cactus – for unit testing server-side java code • Log4j– logging framework, includes e-mailing errors • Struts – web application framework, we use JSPs and Servlets • Java2HTML – creates HTML pages of .java files … continued

  5. Open Source Dependencies, cont. • JUnitDoclet – generates skeleton test cases for a class’s methods • PMD – inspects code for unused variables, parameters, etc. • StrutsMenu – navigation system • StrutsTestCase – extension of Cactus to test Struts’ Actions • WebTest– used to test JSPs • XDoclet – code and deployment descriptor generator

  6. Java Directory Structure src & test org.appfuse… common ejb web

  7. Ant Build File • XML format • In project root directory • Default name: build.xml • Declarative - define steps, not scripty details • Defines a single project • A project contains targets • Targets contain tasks

  8. AppFuse Tasks • Main tasks in appfuse project • clean • ejbdoclet and webdoclet • compile-module (where module is common, web or ejb) • package-module • deploy • test-module

  9. build/deploy process

  10. Test process

  11. XDoclet’s Role • Generates Hibernate mapping files (.hbm.xml) - <ejbdoclet> • Generates Struts’ ActionForms from POJOs - <ejbdoclet> • Generates Validator’s validation.xml from ActionForms - <webdoclet> • Generates web.xml and struts-config.xml - <webdoclet>

  12. XDoclet Examples • Hibernate: User.java • @hibernate.classtable=“app_user" • Generating ActionForms: User.java • @struts.forminclude-all="true"extends=“BaseForm"

  13. XDoclet Examples, cont. • Generating entries in struts-config: UserAction.java • @struts.actionpath="/saveUser"name=“userForm“ scope="request"validate="true" parameter="action" input=“editUser"

  14. User Interface • Constructed with Tiles – web/layouts/baseLayout.jsp controls the entire layout of the site. • Uses Struts JSP tags for editing/saving forms. • Uses JSTL for conditionals, includes and messages.

  15. User Interface, cont. • XHTML 1.0 and CSS 2.0 • Allows validation • Cleaner HTML (all attributes lowercase, etc) • DOCTYPE switching
