我在使用Axis2发布我接口的三个方法时报错

1、首先在服务端直接编写了测试类调用接口的方法，结果是完全正确

2、然后我又在客户端写了一个测试类调用接口的方法，这次失败了，我通过这个错误报文找了很多博客都没能解决

客户端测试类报的错误(这似乎没啥用，不够详细)

//大致意思是axis2框架在实例化某些类或者类的方法时失败了

//下面的大致意思是调用服务端接口的方法时失败

3、最后在浏览器中运行web页面时myeclipse控制台报的错误(在文章最后，现在够详细了)：

这次同样是找博客，在某个地方看了一个帖子说，需要把java连接Oracle数据库用的ojdbc.jar（我用的是ojdbc7.jar）放到了D:\apache-tomcat-7.0.90\webapps\axis2\WEB-INF\lib目录下，嗯然后就没有然后了，还真是这个问题。

其实第一行就告诉我错误原因了，Oracle数据库的驱动加载失败了，但是由于我已经在maven本地仓库导入了ojdbc.jar包，同样项目里的pom.xml文件里也有配置这个jar包，所以当时就没关注这个方向。

其实，使用axis2发布的接口中的方法是运行在axis2框架中，所以在需要连接数据库时，axis2对应的lib目录里也应该包含ojdbc7.jar这个包。

错误报文很长很长，实际后面的错误都是一个错与导致的，当我拷完jar包之后后面的错误全部不见了。

写完文章过去两年多了，现在想起来，当时还是吃了没文化的亏啊，但凡懂一点点JVM 类加载也不至于那么缩手缩脚，日志第一行就已经显示问题了，而不是要等到看到了别人的博客才知道要导入那个jar包。
