我目前正在开发一个Web服务，在本地tomcat 7.0服务器上使用eclipse IDE和axis 2。部署axis2网络服务时出现零头异常
当我尝试部署服务，我得到：

有什么办法找出来，是什么原因导致这种异常？
我的WS的当前版本不读任何配置文件。在构建Web服务时，是否有任何我不能使用的libriries，可能会导致整个演出崩溃？
问候， LuigiEd
我已经解决了这个问题。其中一个W的公共方法有一个名称完全类似于其中一个类属性的参数。虽然这在常规（javaSE）开发中起作用，但它似乎在Web服务中造成麻烦。当我删除参数时，服务器正确部署。任何人都可以向我解释这种行为吗？ – LuigiEdlCarno
