Any public method is exposed as webservice method with default values. In the absence of @WebMethod, the value of the name attribute of the wsdl:operation element MUST be the name of the Java method.
When using method-based injection, it is recommended that the method be declared as non-public, otherwise it will be exposed as a web service operation. Alternatively, the method can be marked with the @WebMethod(exclude=true) annotation to ensure it will not be part of the generated portType for the service.
The javax.jws.WebMethod annotation MAY be used to customize the value of the name attribute of the wsdl:operation element and MUST be used to resolve naming conflicts.
