我导入的jar包有：
commons-fileupload-1.2.1.jar
commons-io-1.3.2.jar
commons-logging-1.0.4.jar
freemarker-2.3.15.jar
ognl-2.7.3.jar
struts2-core-2.1.8.1.jar
xwork-core-2.1.6.jar
javassist-3.11.0.GA.jar
struts filter
[解决办法]
报的错找不到类org/apache/commons/lang3/StringUtils，这个类就是commons-lang这个包里的。
你说你试过没用，可能是你还少其他的包，将这个包导入后，你肯定不是报现在贴出来的这个错。
[解决办法]
struts自带StringUtils 是不是没有导入啊。也就是说struts的包导入不全。
[解决办法]
Caused by: Action class [com.LoginAction] not found - action - file:/D:/apache-tomcat-6.0.36/webapps/struts/WEB-INF/classes/struts.xml:6:55
这么明显的提示 你都不看的啊
找找你的com.LoginAction有没有 看看是不是包名写错了
