java - Jetty server configuration -

i use jetty 9 , have problems configuration. simple rests works fine. problem begun when tried add new headers requests , error handler. way able handle headers adding code every response:

return response.ok(murals)                 .header("access-control-allow-origin", "*")                 .header("access-control-allow-methods", "get, post, delete, put")                 .build();  

server configuration:

        server server = new server(9998);         servletcontexthandler servletcontexthandler = new servletcontexthandler(server, "/", servletcontexthandler.sessions);          servletcontexthandler.addfilter(guicefilter.class, "/*", enumset.allof(dispatchertype.class));         servletcontexthandler.addservlet(defaultservlet.class, "/");          resourceconfig rc = new resourceconfig()                 .register(filterheaders.class)                 .register(exceptionnotfound.class)                 .register(corsfilter.class); //doesnt work         new servletholder(new servletcontainer(rc));          handlerwrapper han = new handlerwrapper();         han.sethandler(new abstracthandler() {              @override             public void handle(string target, request baserequest, httpservletrequest request, httpservletresponse response) throws ioexception, servletexception {                request.setattribute("welcome","hello"); //doesn't work             }         });          servletcontexthandler.addfilter(filters.class, "/*", enumset.of(dispatchertype.request)); //doesnt work          resourcehandler resourcehandler = resourcehandler();         servletcontexthandler.sethandler(resourcehandler);         servletcontexthandler.sethandler(han);         server.start();         server.join(); 

crosfilter class

 public class corsfilter implements containerresponsefilter {          @override         public containerresponse filter(containerrequest request,                 containerresponse response) {              response.gethttpheaders().add("access-control-allow-origin", "*");             response.gethttpheaders().add("access-control-allow-headers",                     "origin, content-type, accept, authorization");             response.gethttpheaders().add("access-control-allow-credentials", "true");             response.gethttpheaders().add("access-control-allow-methods",                     "get, post, put, delete, options, head");              return response;         }      } 

how register headers? doing wrong? not use web configuration.

you mixing jersey 1.x jersey 2.x, should not done. filter class based on jersey 1.x. resourceconfig jersey 2.x. know because jersey 1.x resourceconfig doesn't have register() method. jersey 1.x, howwe register above filter

resourceconfig.getcontainerresponsefilters().add(new corsfilter()); 

and enough. jersey 2.x not have way of adding filters. need register everything.

that being said, if using jersey 2.x, highly suggest getting rid of jersey 1.x dependencies. after doing so, first thing notice filter class no longer compile. here's how refactored 2.x filter should like:

import java.io.ioexception; import javax.ws.rs.container.containerrequestcontext; import javax.ws.rs.container.containerresponsecontext; import javax.ws.rs.container.containerresponsefilter;  @provider public class corsfilter implements containerresponsefilter {      @override     public void filter(containerrequestcontext request,             containerresponsecontext response) throws ioexception {         response.getheaders().add("access-control-allow-origin", "*");         response.getheaders().add("access-control-allow-headers",                 "origin, content-type, accept, authorization");         response.getheaders().add("access-control-allow-credentials", "true");         response.getheaders().add("access-control-allow-methods",                 "get, post, put, delete, options, head");     } } 

using above filter should work.
