Configuring Eclipse for Remote Debugging

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.

build.xml also has the following targets:

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.
