1、Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/httpclient/methods/RequestEntity
at java.lang.Class.getDeclaredConstructors0(Native Method)
原因：缺少webservice的client的jar包
解决方式：myeclipse导入libraries。选择Xfire1.2 HTTP Client Libraries就可以。
2、Exception in thread "main" org.codehaus.xfire.XFireRuntimeException: Could not invoke service.. Nested exception is org.codehaus.xfire.fault.XFireFault: There must be a method name element.
org.codehaus.xfire.fault.XFireFault: There must be a method name element.
原因：请求的结尾加了wsdl
解决方式：去掉wsdl就可以，如：http://localhost/webServiceServer/services/HelloService
3、身份认证的开启和关闭
在service.xml中配置和注销一下文件。即能开启和关闭webservice的password认证
