在tomcat下运行完全正常， 到了这边就不能启动， 是不是我需要改动些什么。 请不吝赐教。
------解决方法--------------------------------------------------------
检查WEB-INF下的Tag配置情况

版本的问题,提示struts标签有问题
------解决方法--------------------------------------------------------
weblogic8.1只支持到J2EE 2.3 JSP 1.2 JSTL 1.0.6
他的JDK是1.4的，tomcat5不一样，你用了新特性的东西肯定会报错
