各位，首先感谢前来帮助。。。 进入正题
环境：Myeclipse9.01 + jdk6.0 + tomcat6.0 + J2EE5 Library
说明：前几天对零配置SSH感兴趣，借鉴前人经验搭了个环境试验，都调通以后，结果出现一个很神奇的错误。我在jsp页面直接写<s:form></s:form>结果报错了。。。错误如下：
2012-3-29 18:08:41 org.apache.catalina.core.StandardWrapperValve invoke
严重: Servlet.service() for servlet jsp threw exception

出错以后，就开始找原因，最终发现加上theme="simple"就一切正常了。我就纳闷了，struts2默认theme不是xhtml么，什么时候成default了？ Template怎么去template/default下面找ftl文件呢？求真相...
配置上，struts只有一个xml文件，使用了struts-conversion-plugin-2.2.3.jar以及struts2-json-plugin-2.2.3.jar，其他的没有什么有struts配置的jar了，我的struts.xml配置如下：
<?xml version="1.0" encoding="UTF-8"?>
