HttpServletResponse object in webservice

[Bob Green]

Hi all,
I have a web application that calls a webservice and from the webservice, I need to get the HttpServletResponse object so that I can redirect to another page of my web application. My question is how to get the HttpServletResponse object from the webservice.

TIA,
Bob

Hi Bob,

I am sorry, but I don't think it is possible. By all means, HttpServletResponse is from the Servlet architecture; while, WebSerive is another kind of animal that use another set of libraries.

You can't use library A and try to find class X in there, where class X belongs to library B.

Anyone, if I am wrong, please correct me. Thanks

While I agree that this is not possible, the reasons are different from the ones mentioned above. Most WS implementations are built on top of servlets, and at least some allow access to HttpServletRequest and Response objects. In Axis, e.g., the code for that would be something like this:

import org.apache.axis.MessageContext;
import org.apache.axis.transport.http.HTTPConstants;
 
MessageContext context = MessageContext.getCurrentContext(); 
HttpServletRequest req = (HttpServletRequest) context.getProperty(HTTPConstants.MC_HTTP_SERVLETREQUEST);

The problem is that WS clients do not expect to be sent redirect messages on an HTTP level, and certainly will not resubmit to a different URL if they get one. The proper thing to do is to send back an error message in the SOAP content which mentions that the WS has moved, and where it can now be found.
