Struts2运用发布的时候注意把开发模式改回FALSE
在www.jhost.cn注册了一个帐号，可以免费使用jsp服务器，支持struts2+hirbernate+spring. 还有免费的sql服务器。 是个不错的免费空间。不过免费还是有限制的。最近好像还开始收费了。
恩，在空间上发布了一个测试struts2的项目，结果弄了几天，没成功过。郁闷，服务器日志老是出错如下：严重: Exception starting filter struts2

就这么个简单的都弄不成，我晕。找了很多网页，问了很多人都不成。最后自己把struts.xml配置文件改了就成了。郁闷。
<constant name="struts.devMode" value="false" /> <!-- 设置开发模式打开 --> 关键是这个要改成false
然后就顺利成功了。
