struts2 运行错误

　　从svn上检出工程后，感觉工程里的jar包有些老，而且前两天刚刚看到有关struts2不安全的问题，然后就把工程中可以替换的jar包挨个替换了，由于之前没有测试，所以这一替换可是报了一堆的错误啊...待我来一个一个地把它们啃掉吧！

　　The first exception：

ERROR 2013-07-22 17:32:38,009 [main] (CommonsLogger.java:38) - Dispatcher initialization failed
java.lang.RuntimeException: java.lang.reflect.InvocationTargetException
    at com.opensymphony.xwork2.inject.ContainerImpl$MethodInjector.inject(ContainerImpl.java:301)
    at com.opensymphony.xwork2.inject.ContainerImpl$ConstructorInjector.construct(ContainerImpl.java:438)
    at com.opensymphony.xwork2.inject.ContainerBuilder$5.create(ContainerBuilder.java:207)

 　　原因：缺少javassist-3.11.0.GA.jar；在工程中引入了ognl-3.0.6.jar，而经过网上查资料并测试，发现ognl是依赖于javassist的，因此会报此错误。

　　The second exception:

　　原因：缺少commons-lang3-3.1.jar；不过导入这个jar包之后紧接着有出了下面的错误，导入了commons-lang-2.4.jar之后还是存在的错误......

　　The third exception:

　　原因：缺少：commons-fileupload-1.3.jar、commons-io-2.0.1.jar;具体原因是从这位大侠这儿获取的！http://tieba.baidu.com/p/573692639?see_lz=1

　　终于，跑过去了，仔细看看也就是缺少了平时用做struts2做工程的一些基本jar包，可以前从来没有研究过jar包，只是从一个工程copy到另一个工程，至于为什么用这些包就真的不晓得了。研究过后可以避免导入本工程不需要的一些jar包，虽然有些jar包并不大，但是内存空间还是能省则省啊！！
