原因分析:E:\Program Files\apache-tomcat-6.0.18\lib下的servlet-api.jar和E:\Program Files\apache-tomcat-6.0.18\webapps\axis2\WEB-INF\lib\servlet-api-2.3.jar
下的jar包冲突,删掉后者,则运行正常.tomcat在启动时就把E:\Program Files\apache-tomcat-6.0.18\lib目录下的jar包全部
加载到内存中,当要加载axis2服务时,就会报错
解决方式:将:\Program Files\apache-tomcat-6.0.18\webapps\axis2\WEB-INF\lib\servlet-api-2.3.jar
下的jar包删除,即可!
