1、在struts-config.xml中添加如下代碼

  <plug-in className="org.apache.struts.validator.ValidatorPlugIn">
  <set-property property="pathnames" value="/org/apache/struts/validator/validator-rules.xml,/WEB-INF/validations.xml"/>

  </plug-in>

2、在WEB-INF下建立validations.xml，假設驗證的form名為inputForm，驗證name,title,content不可為空，代碼如下

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE form-validation PUBLIC
"-//Apache Software Foundation//DTD Commons Validator Rules Configuration 1.3.0//EN"
"http://jakarta.apache.org/commons/dtds/validator_1_3_0.dtd">
<form-validation>
<formset>

</form>

</formset>

</form-validation>

3、設定顯示資訊的資源檔

guest.inputForm.content = content is null
guest.inputForm.name = name is null
guest.inputForm.title = title is null

4、在jsp檔案的<body>前面添加<html:javascript formName="inputForm"/>，並修改<html:form action="/input" >，改為<html:form action="/input" onsubmit="return validateInputForm(this)">
