Subject Re: url-pattern issue during Axis2 integration
Date Tue, 30 Jan 2007 05:52:39 GMT
Lin Sun,

When WebServicesBuilder.findWebServices() is called, the 3rd argument
(Map servletLocations) contains the mapping between the servlet-name
and its context location. For example, there would be a mapping of
'cxfPojoServlet' to '/<war name>/services' or something similar.
