使用处理链处理WEB服务中的请求/响应消息

       这里给出了ant脚本build.xml用来打包EAR,注意在打包之前必须有Web.xml 和 application.xml

build.xml

＜project name="webservices-handler" default="all" basedir="."＞
＜!--  set global properties for this build  --＞
＜property environment="env" /＞
＜property name="compiler" value="modern" /＞
＜property name="debug" value="yes" /＞
＜property name="deprecation" value="yes" /＞
＜property name="build.compiler" value="${compiler}" /＞
＜property name="source" value="." /＞
＜property name="build" value="${source}/build" /＞
＜property name="war_file" value="BalanceEnquiry.war" /＞
＜property name="ear_file" value="BalanceEnquiry.ear" /＞
＜property name="namespace" value="http://www.bea.com" /＞
＜property name="client.classes.dir" value="{source}/clientclasses" /＞
＜target name="all" depends="clean, war, ear" /＞
＜target name="clean"＞
＜delete dir="${build}" /＞
＜delete file="${source}/${ear_file}" /＞
＜delete file="${war_file}" /＞
＜/target＞
＜target name="war"＞
＜delete dir="${build}" /＞
＜mkdir dir="${build}" /＞
＜mkdir dir="${build}/WEB-INF" /＞
＜mkdir dir="${build}/WEB-INF/classes" /＞
＜javac srcdir="${source}" includes="AuthenticationHandler.java,
                          BalanceEnquiryService.java"
                          destdir="${build}/WEB-INF/classes" /＞
＜copy todir="${build}/WEB-INF"＞
＜fileset dir="${source}"＞
＜include name="web-services.xml" /＞
＜include name="web.xml" /＞
＜/fileset＞
＜/copy＞
＜jar jarfile="${war_file}" basedir="${build}" /＞
＜/target＞
＜target name="ear" depends="war"＞
＜delete dir="${build}" /＞
＜mkdir dir="${build}" /＞
＜mkdir dir="${build}/META-INF" /＞
＜copy todir="${build}"＞
＜fileset dir="${source}"＞
＜include name="${war_file}" /＞
＜/fileset＞
＜/copy＞
＜copy todir="${build}/META-INF"＞
＜fileset dir="${source}"＞
＜include name="application.xml" /＞
＜/fileset＞
＜/copy＞
＜jar jarfile="${source}/${ear_file}" basedir="${build}" /＞
＜/target＞
＜/project＞

       ant脚本在创建WAR文件的同时也进行EAR打包，在WEBLOGIC服务器上部署打包好的EAR文件，下面是客户端调用余额查询的程序：
