您缺少 OGNL 库。

首先，您需要更改struts.xml文件。将其更改为：

    <action name="getTutorial" class="org.prem.javabrain.action.TutorialAction">
        <result name="success">/success.jsp</result>    
        <result name="failure">/error.jsp</result>
    </action>

其次，您需要检查所有库（尤其是 jar ognl jar）是否在您的类路径中。可能，您可以发布您在类路径中拥有的 jar 列表。

struts.xml 文件不正确。结果标签应该在动作标签内。

我建议您在 xml 文件中使用 DTD 定义，这将有助于检查 XML 文件的语法。在 struts.xml 文件的第一行之后添加这一行：

  <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"  "http://struts.apache.org/dtds/struts-2.0.dtd">

此 DTD 将帮助 IDE 在您进行开发时向您建议正确的 XML 语法。

所以最终的 struts.xml 文件看起来有点像这样：

<?xml version="1.0" encoding="UTF-8"?>
<!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">
        <action>name="getTutorial" class="org.prem.javabrain.action.TutorialAction">
            <result name="success">/success.jsp</result>    
            <result name="failure">/error.jsp</result>
        </action>
    </package>
</struts>

希望这可以帮助：）
