Deprecated.

@Deprecated
public class XdbServletAdapter
extends ServerAdapter

HTTP adapter from Servlet calls to Restlet calls. This class can be used in any Servlet, just create a new instance and override the service() method in your Servlet to delegate all those calls to this class's service() method. Remember to set the target Restlet, for example using a Restlet Router instance. You can get the Restlet context directly on instances of this class, it will be based on the parent Servlet's context for logging purpose.

This class is especially useful when directly integrating Restlets with Spring managed Web applications. Here is a simple usage example:

 public class TestServlet extends HttpServlet {
     private ServletAdapter adapter;
 
     public void init() throws ServletException {
         super.init();
         this.adapter = new XdbServletAdapter(getServletContext());
 
         Restlet trace = new Restlet(this.adapter.getContext()) {
             public void handle(Request req, Response res) {
                 getLogger().info("Hello World");
                 res.setEntity("Hello World!", MediaType.TEXT_PLAIN);
             }
         };
 
         this.adapter.setTarget(trace);
     }
 
     protected void service(HttpServletRequest req, HttpServletResponse res)
             throws ServletException, IOException {
         this.adapter.service(req, res);
     }
 }

Parameters:

context - The Servlet context.

target - The Restlet target.

Method Detail

getBaseRef

public Reference getBaseRef(javax.servlet.http.HttpServletRequest request)

Deprecated.

Returns the base reference of new Restlet requests.

Parameters:

request - The Servlet request.

Returns:

The base reference of new Restlet requests.

getRootRef

public Reference getRootRef(javax.servlet.http.HttpServletRequest request)

Deprecated.

Returns the root reference of new Restlet requests. By default it returns the result of getBaseRef().

Parameters:

request - The Servlet request.

Returns:

The root reference of new Restlet requests.

getTarget

public Restlet getTarget()

Deprecated.

Returns the target Restlet.

Returns:

The target Restlet.

service

public void service(javax.servlet.http.HttpServletRequest request,
                    javax.servlet.http.HttpServletResponse response)
             throws javax.servlet.ServletException,
                    IOException

Deprecated.

Services a HTTP Servlet request as a Restlet request handled by the "target" Restlet.

Parameters:

request - The HTTP Servlet request.

response - The HTTP Servlet response.

Throws:

javax.servlet.ServletException

IOException

setTarget

public void setTarget(Restlet target)

Deprecated.

Sets the target Restlet.

Parameters:

target - The target Restlet.

toRequest

public HttpRequest toRequest(XdbServletCall servletCall)

Deprecated.

Converts a low-level Servlet call into a high-level Restlet request. In addition to the parent HttpServerConverter class, it also copies the Servlet's request attributes into the Restlet's request attributes map.

Parameters:

servletCall - The low-level Servlet call.

Returns:

A new high-level uniform request.
