小弟我刚学WEBWORK框架遇到一1个问题请帮忙解决！

Question

加载xwork.xml文件时报错了，
xwork" must match "(package|include)*看看你的xwork.xml写的对不对。

Answer 1

<!DOCTYPE xwork PUBLIC "-//OpenSymphony Group//XWork 1.0//EN" "http://www.opensymphony.com/xwork/xwork-1.0.dtd"><xwork>
<include file="webwork-default.xml" />
<include file="config-browser.xml"/>
<action name="hello" class="MyTest.HelloAction">
<result name="success" type="dispatcher">
<param name="location">/greetings.jsp</param>
</result>
</action>
</xwork>
这就是我xwork.xml里的全部内容 不知道是哪错了？

我把xwork.xml里的内容改了点 上面的那个错误就没有了但出现 新的错误 郁闷啊！
<!DOCTYPE xwork PUBLIC "-//OpenSymphony Group//XWork 1.0//EN" "http://www.opensymphony.com/xwork/xwork-1.0.dtd"><xwork><include file="webwork-default.xml" /><package name="examples" extends="webwork-default">
<action name="hello" class="MyTest.HelloAction">
<result name="success" type="dispatcher">
<param name="location">/greetings.jsp</param>

你的xwork 没有 <package/>!

Answer 5

org.xml.sax.SAXParseException: The content of element type "xwork" must match "(package|include)*".注意xml的规则
