Answer 1

你的jdk配置错误了吧？C:\Program Files\Java\jdk1.6.0_10\bin;

Answer 2

你 写的 过滤器代码！有点问题吧！要不就是xml里边的配置有问题！

Answer 3

java.lang.NoClassDefFoundError: org/apache/commons/lang/StringUtils  
缺少commons-这个jar包

Answer 4

显然是缺失了apache的一个jar，你查找下classpath中是否有commons-lang.jar(不是很清楚具体的名字)这个样的jar，没有加上；应该在struts2的lib下有;

Answer 5

java.lang.NoClassDefFoundError: org/apache/commons/lang/StringUtils缺少commons-lang.jar？？
或者有多个版本的commons-lang.jar导致冲突？？
commons-lang.jar或者是版本太老？？

Answer 9

Struts2基本需要使用的jar包：
commons-fileupload-1.2.2.jar
commons-io-2.0.1.jar
commons-lang-2.5.jar
freeer-2.3.16.jar
javassist-3.11.0.GA.jar
ognl-3.0.1.jar
struts2-core-2.2.3.1.jar
xwork-core-2.2.3.1.jar
你把包都导了再说

Answer 10

javassist-3.11.0.GA.jar
昨天导了这两个包就好了但是后来我又把javassist-3.11.0.GA.jar删除后，就只加下面几个包他又能运行了，这是咋
freeer-2.3.16.jar
ognl-3.0.1.jar
struts2-core-2.2.3.1.jar
xwork-core-2.2.3.1.jar
commons-logging-1.1.1.jar

Answer 11

你查看下Tomcat中的这个webApp(就是你的这个login程序)中的lib，运行时这个才是JVM查找的classpath，一般来说你有改动，应该重新部署。
