1、配置struts.xml時Action中不配置namespace，默認namespace為 “ ”

struts.xml中

<package name="test" extends="struts-default" >

<action name="init_action" class="com.wei.action.LoginAction" method="init">
<result>/login.jsp</result>
</action>
</package>

jsp中

<form action="init_action.action" method="post">
用 戶 名：<input type="text" name="user" value="" maxlength="20" size="20"><br>
密 碼： <input type="password" name="pwd" value="" maxlength="20" size="20"><br>
確認密碼：<input type="password" name="pwd" value="" maxlength="20"size="20"> <br>
<input type="submit" name="login" value="登錄">
</form>

2、配置struts.xml時Action中配置namespace=“/test ”

struts.xml中

<package name="test" extends="struts-default" namespace=/test“”>

<action name="init_action" class="com.wei.action.LoginAction" method="init">
<result>/login.jsp</result>
</action>
</package>

jsp中

<form action="test/init_action.action" method="post">
用 戶 名：<input type="text" name="user" value="" maxlength="20" size="20"><br>
密 碼： <input type="password" name="pwd" value="" maxlength="20" size="20"><br>
確認密碼：<input type="password" name="pwd" value="" maxlength="20"size="20"> <br>
<input type="submit" name="login" value="登錄">
</form>
