我的服务发布的时候总是出现莫名其妙的错误，我google了半天，都没有想要的东东
哪位能帮我解决一下，先谢过！


下面是出错的信息：
AXIS error
Sorry, something seems to have gone wrong... here are the details:
Fault - ; nested exception is:
WSDLException: faultCode=OTHER_ERROR: Can't find prefix for 'http
://sql.java'. Namespace prefixes must be set on the Definition object u
sing the addNamespace(...) method.:

faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server.userException

or 'http://sql.java'. Namespace prefixes must be set on the Defini
tion object using the addNamespace(...) method.:

下面是发布的服务，

我发布服务的时候
如果在方法printTable()中加入参数Connection
则会出现上面的错误

如果不加任何的参数，则不会出现任何的错误，能够成功发布
不知道什么原因
