遇到这个异常懵逼了很长时间才解决，axis2框架个人感觉进行接口相互调用还是比较麻烦的，

调了很长时间，我由a项目调用b项目的接口时，一直报这个错，在网上找了很长时间，也没找到

解决的办法，自己慢慢的调的过程中得以解决，现在总结一下。

1.异常展示：

2.异常分析：报未知异常，我在确认生成的客户端和服务端的配置文件没有问题的时候，就仔细检查代码，

发现我的A项目挑用B项目接口时，打断点是可以进入B项目接口，由于打的断点次数比较多，在断点调试的过程

中，容易出现卡壳，我把项目清理了一遍，重新调试，断点进入到B项目接口中时，一步一步的调，然后遇到以下异常

java.lang.NullPointerException

紧接着A项目中报了一个unknown的异常，当我把B项目接口中的异常解决之后，unknown异常也就解决了。

3.经验总结：在刚开始出现问题的时候，一直是先让项目运行，检查是否报异常，

由于在tomcat中配置了两个项目同时运行，因为控制台会默认显示客户端的日志文件，

服务端的日志文件则需要切换后才可查看，如上图所示，检查异常需要非常仔细，才可以快速

定位到异常所在。
