Overwrite the webservice @WebContext annotation using XML file

We are using Jboss 4.2.3 GA ,which support JAXWS webservices. Webservice also as Stateless EJB. The deployment path of jar file is under webservices.war->webserviceEJB.jar. Using @webContext annotation the webservice is running on SSL. To avoid code change any XML configuration file is required which can define the @WebContext values for tranport-guarantee attribute.All the websevices has @WebContext with auth-method =BASIC and transport-guarantee =NONE. We need to overwrite the annontation using XML file.
The idea of using configuration files is Webservices need to be configured in jboss either on http or https. Please reply that jboss 4.2.3GA support @WebContext values in configuration file for SSL and the required dependancy jars.
