Re: how to pass authentication credentials to service class in cxf webservice

[Freeman Fang <fr...@gmail.com>]

Hi,

In your interceptor you can save the authentication parameter in  
message, and in your impl class you can  have code like

@Resource
     private WebServiceContext wsContext;

Then can use code like
             MessageContext ctx = wsContext.getMessageContext();
             Message message =  
((WrappedMessageContext)ctx).getWrappedMessage();
             //here you can get authentication parameter  you saved  
previously from message
