resin3.0.12下面部署的struts2+spring+ibatis应用报错。

比较奇怪，我在windows下面用的是resin3.0.18没有任何问题，但是到了服务器上面resin3.0.12下面就报错，而且是我在jsp里面的“<s:textfield name="user.username" label="用户名" required="true"/>”这条错误，我觉得有可能是在加载struts2的配置文件的时候有问题。

请问有那位配置过类似环境的能指点一下吗，多谢了！！！

刚才测试找到问题具体位置：
是在加载struts-default.xml的时候出错。
好像是resin没有能够读出配置文件，报空指针错误。
