the required fields on the targets.xml file are: -

[CODE}
<target name="init">
<tstamp />
</target>

<path id="capture.schema.classpath">
<fileset dir="${C:/Sun/AppServer}/lib">
<include name="appserv-cmp.jar"/>
</fileset>
</path>

<target name="prepare" depends="init"
description="Create build directories.">
<mkdir dir="C:/Sun/AppServer/" />
</target>

<target name="build" depends="prepare"
description="Compile source code" >
<javac srcdir="src" destdir="${build}" >
<include name="**/*.java" />
<classpath refid="classpath"/>
</javac>
</target>

good use
