With this command, ant will use the targets defined in the jboss-build.xml file to build the College Fest application and deploy it to the JBoss server. Take a special look at <target name="deploy" ...>, here is where the jboss-build.xml tell ant where to deploy the WAR file. The following example shows the definitions in the jboss-build.xml file.

    <property name="dest.dir" value="bin"/>
    
    <target name="clean" description="Delete all generated files">
        <echo message="Deleting bin directory" />
        <delete dir="bin" />
    </target>

		</javac>
	</target>

	<target name="war" depends="compile">

			<zipfileset dir="pix" prefix="pix"/>   	 
			<classes dir="${dest.dir}"/>   
                        <webinf dir="WEB-INF" />

	</target>

	<target name="deploy" depends="war">

	</target>

    </target>
</project>

The war created by the ant build contains a JBoss specific deployment descriptor, the jboss-web.xml file in the WEB-INF directory of the WAR is shown in the following example.

</jboss-web>

Note

The following geronimo-web.xml was generated using the J2G tool.

Last time you built the College Fest sample application it was configured for ant to use the jboss-build.xml file instead of the default build.xml. The following example shows the content of the default build.xml file.
