Building and Deploying with Ant
The compiling, packaging, and deploying of the web application is done in the Eclipse IDE with an Ant build.xml file. Develop an Ant build.xml file that consists of targets to compile the JBossServlet.java file and package and deploy the webapp.war web application. The build.xml file is listed below:
<project name="jbossApp" default="webapp" basedir=".">
<property name="build" value="build"/>
<property name="src" value="." />
<property name="jboss.deploy"
value="C:\JBoss\jboss-4.0.2\server\default\deploy"/>
<property name="dist" value="dist"/>
<property name="j2sdkee" value="C:\J2sdkee1.4"/>
<target name="init">
<tstamp/>
<mkdir dir="${build}" />
<mkdir dir="${dist}" />
<mkdir dir="${build}/WEB-INF" />
<mkdir dir="${build}/WEB-INF/classes" />
</target>
<target name="compile" depends="init">
<javac debug="true" classpath="${j2sdkee}/lib/j2ee.jar"
srcdir="${src}/WEB-INF/classes"
destdir="${src}/WEB-INF/classes">
<include name="**/*.java" />
</javac>
<copy todir="${build}/WEB-INF">
<fileset dir="WEB-INF" >
<include name="web.xml" />
</fileset>
</copy>
<copy todir="${build}/WEB-INF/classes">
<fileset dir="${src}/WEB-INF/classes" >
<include name="**/JBossServlet.class" />
</fileset>
</copy>
</target>
<target name="webapp" depends="compile">
<war basedir="${build}" includes="**/*.class"
destfile="${dist}/webapp.war" webxml="WEB-INF/web.xml"/>
<copy file="${dist}/webapp.war" todir="${jboss.deploy}"/>
</target>
</project>
The build.xml file has the properties listed in the following table.
| Property | Description |
build |
The build directory used to build the web application. |
src |
The src directory has the source files for the web application. |
jboss.deploy |
The JBoss directory in which the web application is deployed. |
dist |
The directory in which the web application .war file is generated. |
j2sdkee |
The J2sdkee directory. |
build.xml also has the following targets:
| Target | Description |
init |
The initialization target; the target to create the web application directories. |
compile |
The target to compile the web application. |
webapp |
The target to generate the .war file. |
The debug attribute of the javac task
in the build target is set to true to
enable compilation in debug mode. By compiling an
application in debug mode, the line number that generates the
exception in a JBoss server application gets displayed in Eclipse's
Debug perspective.
