如题！

Answer 1

我抄一个例子给你,自己去领会吧。build.properties:classpath.external=C\:\\ExadelStudio\\lib\\servlet\\2.3\\servlet.jar;build.xml:
<project name="empty" basedir="../" default="build">    <!-- Local system paths -->
    <property file="${basedir}/ant/build.properties"/>
    <!--property name="deploy.dir" value="${exadel.home}/tomcat/webapps"/-->
    <property name="webroot.dir" value="${basedir}/WebContent"/>
    <property name="webinf.dir" value="${webroot.dir}/WEB-INF"/>
    <property name="build.dir" value="build"/>    <!-- Project settings -->
    <property name="project.distname" value="empty"/>    <!-- classpath for Struts 1.1 -->
    <path id="compile.classpath">
        <pathelement path ="${webinf.dir}/lib/commons-beanutils.jar"/>
        <pathelement path ="${webinf.dir}/lib/commons-digester.jar"/>
        <pathelement path ="${webinf.dir}/lib/struts.jar"/>
        <pathelement path ="${webinf.dir}/classes"/>
        <pathelement path ="${classpath.external}"/>
        <pathelement path ="${classpath}"/>
    </path>    <!-- Check timestamp on files -->
    <target name="prepare">
        <tstamp/>
    </target>    <!-- Copy any resource or configuration files -->
    <target name="resources">
        <copy todir="${webinf.dir}/classes" includeEmptyDirs="no">
            <fileset dir="JavaSource">
            <patternset>
                <include name="**/*.conf"/>
                <include name="**/*.properties"/>
                <include name="**/*.xml"/>
            </patternset>
            </fileset>
        </copy>
    </target>    <!-- Normal build of application -->
    <target name="compile" depends="prepare,resources">
        <javac srcdir="JavaSource" destdir="${webinf.dir}/classes">
            <classpath refid="compile.classpath"/>
        </javac>
    </target>    <!-- Remove classes directory for clean build -->
    <target name="clean"
      description="Prepare for clean build">
      <delete dir="${webinf.dir}/classes"/>
      <mkdir  dir="${webinf.dir}/classes"/>
    </target>    <!-- Build entire project -->
    <target name="build" depends="prepare,compile"/>
    <target name="rebuild" depends="clean,prepare,compile"/></project>

Answer 2

有用的其实是这部分      <path   id= "compile.classpath "> 
                <pathelement   path   = "${webinf.dir}/lib/commons-beanutils.jar "/> 
                <pathelement   path   = "${webinf.dir}/lib/commons-digester.jar "/> 
                <pathelement   path   = "${webinf.dir}/lib/struts.jar "/> 
                <pathelement   path   = "${webinf.dir}/classes "/> 
                <pathelement   path   = "${classpath.external} "/> 
                <pathelement   path   = "${classpath} "/> 
        </path>
