If you do not want a WSDL to be generated, you have to supply one and, in the @WebService annotation (assuming you use it), use the wsdlLocation element to specify the location of the WSDL.
Usually, WSDL documents included in WAR-files are lcoated in the WEB-INF/wsdl directory.
i don't know what Webservice annotation is. it's wierd when i look at the WSDL file i see minoccurs property. But when i call the service as a client from internet explorer i can't see minoccurs property.
