Architecture
Directory Structure,
Build/Test/Deploy Processes
Project Structure

Directory structure
– Simpler is better
– Map to artifacts
– Customizations/personalization's
– IDE issues
– Separate source from artifacts - cleanable

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



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

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

Default name: build.xml
Declarative - define steps, not scripty details
Defines a single project
A project contains targets
Targets contain tasks

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 strutsconfig.xml - <webdoclet>

XDoclet Examples

Hibernate: User.java
– @hibernate.class table=“app_user"

Generating ActionForms: User.java
– @struts.form include-all="true"
extends=“BaseForm"
XDoclet Examples,
cont.

Generating entries in struts-config:
UserAction.java
– @struts.action path="/saveUser"
name=“userForm“
scope="request" validate="true"
parameter="action"
input=“editUser"
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.

User Interface, cont.

XHTML 1.0 and CSS 2.0
– Allows validation
– Cleaner HTML (all attributes lowercase,
etc)
– DOCTYPE switching
