在做所有的配置前，先检查jsp页面是否有以下内容(没有请添加上)：
<%-- Error Messages --%>
<logic:messagesPresent>
    <div class="error">
        <html:messages id="error">
            <c:out value="${error}"/><br/>
        </html:messages>
    </div>
</logic:messagesPresent>

<%-- Success Messages --%>
<logic:messagesPresent message="true">
    <div class="message">
        <html:messages id="message" message="true">
            <c:out value="${message}"/><br/>
        </html:messages>
    </div>
</logic:messagesPresent>

其中的css可以自己根据需要定义，上面使用JSTL标签.

使用validator需要进行如下配置：
1) 首先在struts-config.xml中添加:
<plug-in className="org.apache.struts.validator.ValidatorPlugIn">
    <set-property property="pathnames" value="/WEB-INF/validator-rules.xml, /WEB-INF/validation.xml"/>
</plug-in>

2) 配置validation.xml文件，内容如下：
<form-validation>
    <formset>
        <form name="loginForm">
            <field property="userid" depends="required">
                <arg0 key="login.user.id" />
            </field>
            <field property="password" depends="required">
                <arg0 key="login.password" />
            </field>
            <field property="repasswd" depends="required">
                <arg0 key="login.password.retry" />
            </field>
            <field property="username" depends="required">
                <arg0 key="login.username" />
            </field>
            <field property="sex" depends="required">
                <arg0 key="login.sex" />
            </field>
            <field property="college" depends="required">
                <arg0 key="login.college" />
            </field>
            <field property="department" depends="required">
                <arg0 key="login.department" />
            </field>
            <field property="idNumber" depends="required">
                <arg0 key="login.id.number" />
            </field>
            <field property="birthday" depends="required, date">
                <arg0 key="login.birthday" />
            </field>
            <field property="telephone" depends="required">
                <arg0 key="login.telephone" />
            </field>
            <field property="email" depends="required, email">
                <arg0 key="login.email" />
            </field>
        </form>
    </formset>
</form-validation>


3) 在struts中设置对应的action的validate值为true：
<action path="/login" name="loginForm" parameter="method" type="com.timeshonor.struts.action.LoginAction" validate="true" input="/login.jsp">
    <forward name="success" path="/success.jsp" />
</action>
如果使用的是动态Form，则在struts-config.xml中会有如下配置：
<form-bean name="loginForm" type="org.apache.struts.validator.DynaValidatorForm">
    <form-property name="userid" type="java.lang.String" />
    <form-property name="password" type="java.lang.String" />
    <form-property name="repasswd" type="java.lang.String" />
    <form-property name="username" type="java.lang.String" />
    <form-property name="sex" type="java.lang.String" />
    <form-property name="college" type="java.lang.String" />
    <form-property name="department" type="java.lang.String" />
    <form-property name="idNumber" type="java.lang.String" />
    <form-property name="birthday" type="java.lang.String" />
    <form-property name="telephone" type="java.lang.String" />
    <form-property name="email" type="java.lang.String" />
</form-bean>
注：validator插件不支持struts的ActionForm验证，只支持DynaValidatorForm和ValidatorForm验证，如果不使用动态form可以让需要验证的Form类从ValidatorForm继承，不需要实现validate方法.

4) 执行完1、2、3步就可以执行UI服务器端验证，如果想配置前台javascript验证时，还需要做如下配置：
a) 修改对应的页面form 为如下内容：
<html:form action="/login" method="post" onsubmit="return validateLoginForm(this);">
b) 确保下面这一行内容在对应页面的form里：
<html:submit>提交</html:submit>
c) 在页面的form元素后面添加以下内容：
<html:javascript formName="loginForm" dynamicJavascript="true" staticJavascript="true" />

        <filter-name>SecurityFilter</filter-name>
        <url-pattern>*.do</url-pattern>
    </filter-mapping>

    <filter-mapping>
        <filter-name>CharacterEncoding</filter-name>
        <url-pattern>*.do</url-pattern>
    </filter-mapping>

    <filter-mapping>
        <filter-name>CharacterEncoding</filter-name>
        <url-pattern>*.jsp</url-pattern>
    </filter-mapping>

根据servlet2.3规范filter执行是按照web.xml配置的filter-mapping先后顺序进行执行，所以上面的配置会导致遇见*.do的url请求，先进行SecurityFilter的过滤器处理，这时候没有做编码处理，已经是乱码，到下面的filter处理时已经时乱码，再做编码处理已经没有用处。

修正方式，调整filter-mapping顺序，如下：

    <filter-mapping>
        <filter-name>CharacterEncoding</filter-name>
        <url-pattern>*.do</url-pattern>
    </filter-mapping>

    <filter-mapping>
        <filter-name>CharacterEncoding</filter-name>
        <url-pattern>*.jsp</url-pattern>
    </filter-mapping>

    <filter-mapping>
        <filter-name>SecurityFilter</filter-name>
        <url-pattern>*.do</url-pattern>
    </filter-mapping>

activation.jar

axis.jar

axis-ant.jar

commons-discovery-0.2.jar

commons-logging-1.0.4.jar

jaxrpc.jar

log4j-1.2.8.jar

log4j.properties

mail.jar

saaj.jar

wsdl4j-1.5.1.jar

 

2.      在工程的根下建立 build.xml 文件，内容如下：

<? xml version = "1.0" encoding = "UTF-8" ?>

 

< project name = "webservice" default = "all" basedir = "." >

    < property name= "build.lib.dir" value="build-lib" />

 

    <!-- change these variable base on your environment -->

    < property name = "src.dir" value = "src" />

    < property name = "classpath" value = "${build.lib.dir}/axis" />

    < property name = "remote.wsdl" value = "http://10.64.3.20/test/ws/Service1.asmx?wsdl" />

    < property name = "webservice.namespace" value = "http://tempurl.org" />

 

    < path id = "axis.classpath" >

       < fileset dir = "${classpath}" >

           < include name = "**/*.jar" />

       </ fileset >

    </ path >

 

    < taskdef resource = "axis-tasks.properties"

      classpathref = "axis.classpath" />

 

    < target name = "wsdl2java" description = "Generate Java file from WSDL URL by WSDL2JAVA" >

       < axis-wsdl2java output = "${src.dir}" testcase = "true" verbose = "true" url = "${remote.wsdl}" >

           < mapping namespace = "${webservice.namespace}" package = "org.tempuri" />

       </ axis-wsdl2java >

    </ target >

 

    < target name = "clean" description = "Clean output directories" >

        < delete dir = "${src.dir}/org/tempuri" />

    </ target >

 

    < target name = "all" depends = "clean, wsdl2java" >

    </ target >

 

</ project >

 

注意：对应你的项目进行修改以上的变量设置

 

3.      直接运行 ant ，生成 webservice 的代理类，使用 eclipse 的 refactor 功能重命名包名

 

4.      调用本地代理类操作 webservice

分析原因：oracle自己内置jdk1.3，安装后将jdk1.3添加到path的前端，导致eclipse3.1的默认jvm为jdk1.3，而eclipse3.1的jdk要求至少为1.4，所以启动失败。

解决方法：修改系统的PATH环境变量，进入"我的电脑"->"属性"->"高级"->"环境变量"->"系统变量"->PATH->编辑，将%JAVA_HOME%\bin;移至到oralce的jre(类似C:\Program Files\Oracle\jre\1.1.8\bin)前面即可。
