首先，假设我们的项目的结构如下 ${project.root}
  |
  +-- build/           <-- WAR/EAR档的目录
  +-- classes/         <-- 编译的输出目录，与JBuilder兼容
  +-- src/             <-- Java源文件目录
  +-- web/             <-- WEB Content 目录
  |    |
  |    +--pages/       <-- JSP 文件目录
  |    +--WEB-INF/     <-- web.xml 等配置文件
  +-- ejb              <-- EJB Content 目录
  |    |
  |    +---INF/    <-- EJB 配置文件
  +-- ear              <-- EAR Content 目录
  |    |
  |    +---INF/    <-- EAR 配置文件
  |-- lib              <-- 项目所要用到的library

接下来第一步，就是要先定义好一些全局的参数，以便以后更改起来方便，风格
大家自己选择好了，我用的是如下的方式：

(1) 给出项目的目录：
  <!--// project directories //--><property name="dir.project" ="D:/Code/MyProject"/><property name="dir.project.lib" ="${dir.project}/lib"/><property name="dir.project.src" ="${dir.project}/src"/><property name="dir.project.web_module" ="${dir.project}/web"/><property name="dir.project.ejb_module" ="${dir.project}/ejb"/><property name="dir.project.ear_module" ="${dir.project}/ear"/><!--// compile, build and deploy directories //--><property name="dir.project.compile" ="${dir.project}/classes"/><property name="dir.project.compile.jspcache" ="${dir.project.compile}/jspcache"/><property name="dir.project.build" ="${dir.project}/build"/><!--// J2EE Container //--><property name="dir.appserver.tomcat.home" ="D:/J2EE_HOME/AppServer/Tomcat"/><property name="dir.appserver.oc4j.j2ee.home" ="D:/J2EE_HOME/AppServer/OC4J/j2ee/home"/>
 

(2) 定义Java Source的编译选项
<!--// Java compiler options //--> <property name="opt.compile.source" ="1.4"/><property name="opt.compile.target" ="1.4"/><property name="opt.compile.encoding" ="UTF-8"/><property name="opt.compile.deprecation" ="on"/><property name="opt.compile.debug" ="on"/><property name="opt.compile.optimize" ="off"/>
 

(3) 如果需要 import EJB library 的话，给出下面的定义，后面会用到
    <!--// EJB imported resource //--><property name="import.ejb.report.server" ="${dir.project.lib}/Appwork.jar"/>
 

(4) 给出部署WAR/EAR文件的名称：
  <!--// Deployment //--><property name="deploy.file.ejb_module" ="MyApp_EJB.jar" /><property name="deploy.file.web_module" ="MyApp_WEB.war" /><property name="deploy.file.ear_module" ="MyApp.ear" />
 

(5) 给出CLASSPATH的定义，引入相关的Library和项目编译生成的Java Classes
  <path id="CLASSPATH"><!--// Tomcat Libraries //--><fileset dir="${dir.appserver.tomcat.home}/bin"> <include name="*.jar"/></fileset> <fileset dir="${dir.appserver.tomcat.home}/server/lib"> <include name="*.jar"/> </fileset> <fileset dir="${dir.appserver.tomcat.home}/common/lib"> <include name="*.jar"/> </fileset> <!--// Depended Libraries //--><pathelement location="${dir.project.lib}/abc.jar"/><pathelement location="${dir.project.lib}/AppServer.jar"/><pathelement location="${dir.project.lib}/AppServiceClient.jar"/><pathelement location="${dir.project.lib}/AppUtil.jar"/><pathelement location="${dir.project.lib}/xport.jar"/><pathelement location="${dir.project.lib}/jaxen-full.jar"/><pathelement location="${dir.project.lib}/jstl.jar"/><pathelement location="${dir.project.lib}/log4j-1.2.13.jar"/><pathelement location="${dir.project.lib}/ojdbc14.jar"/><pathelement location="${dir.project.lib}/saxpath.jar"/><pathelement location="${dir.project.lib}/standard.jar"/><pathelement location="${dir.project.lib}/taglibs-log.jar"/><!--// Project classes //--><pathelement location="${dir.project.compile}"/></path>
 

(6) 基本的clean和init的task
  <target name="clean"><delete dir="${dir.project.build}"/><delete dir="${dir.project.compile.jspcache}"/><delete dir="${dir.project.compile}"/><delete dir="${dir.project.web_module}/WEB-INF/classes"/><delete dir="${dir.project.web_module}/WEB-INF/lib"/></target><target name="init"><mkdir dir="${dir.project.compile}"/><mkdir dir="${dir.project.compile.jspcache}"/><mkdir dir="${dir.project.web_module}/WEB-INF/classes"/><mkdir dir="${dir.project.web_module}/WEB-INF/lib"/><mkdir dir="${dir.project.build}"/></target>
 

(7) 编译Java Source
<target name="src_compile" depends="init"><!--// compile the Java source //--><javac srcdir="${dir.project.src}" destdir="${dir.project.compile}" encoding="${opt.compile.encoding}" source="${opt.compile.source}" target="${opt.compile.source}" deprecation="${opt.compile.deprecation}"debug="${opt.compile.debug}" optimize="{opt.compile.optimize}" ><classpath refid="CLASSPATH"/><include name="**/*.java"/></javac><!--// copy the classpath resources //--><copy todir="${dir.project.compile}"><fileset dir="${dir.project.src}"><exclude name="**/*.java"/></fileset></copy> </target>
 

(8) 预编译JSP文件，可选择基于Tomcat或是Oracle Application Server
  <!--// for Tomcat //--> <target name="jsp_src_generate" depends="src_compile"><taskdef classname="org.apache.jasper.JspC" name="jasper2"><classpath refid="CLASSPATH"/> </taskdef><jasper2 validateXml="false" verbose="9"uriroot="${dir.project.web_module}" outputDir="${dir.project.compile.jspcache}" webXmlFragment="${dir.project.compile.jspcache}/generated-web.xml" /> </target><target name="jsp_src_compile"><javac srcdir="${dir.project.compile.jspcache}" destdir="${dir.project.compile.jspcache}" encoding="${opt.compile.encoding}" source="${opt.compile.source}" target="${opt.compile.source}" deprecation="${opt.compile.deprecation}"debug="${opt.compile.debug}" optimize="{opt.compile.optimize}" ><classpath refid="CLASSPATH"/><include name="**"/></javac></target><target name="jsp_precompile" depends="src_compile, jsp_src_generate, jsp_src_compile" />
