這裏是我的struts.xml

<!DOCTYPE struts PUBLIC 
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" 
"http://struts.apache.org/dtds/struts-2.0.dtd"> 
<struts> 
    <package name="default" extends="struts-default"> 
     <!-- Configuration for the default package. --> 

    <action name="register" class="hello.model" method="register"> 
     <result name="success">/success.jsp</result>  
    </action> 
    <action name="update" class="hello.model" method="update">

    <action name="logout" class="hello.model" class="logout" > 
     <result name="success">/login.jsp</result> 
    </action> 
</package> 

Answer 1

你有錯誤的語法在struts.xml。 DTD用於驗證由Xerces分析的xml元素的語法。操作元素不允許有多個class屬性。

更改代碼

<action name="logout" class="hello.model" class="logout" > 
    <result name="success">/login.jsp</result> 
</action> 

到

<action name="logout" class="hello.model" > 
    <result name="success">/login.jsp</result> 
</action> 

Answer 2

這是問題：Caused by: org.xml.sax.SAXParseException; systemId: file:/D:/NetBeansProjects/finalsFINALS/build/web/WEB-INF/classes/struts.xml; lineNumber: 29; columnNumber: 65; Attribute "class" was already specified for element "action".請檢查你的struts.xml文件或在這裏上傳求助
