Glassfish 3.1.2 및 Grizzly가있는 웹 소켓 - 예기치 않은 응답 코드 : 405

Question

로컬 Glassfish 3.1.2 서버 설치에서 websocket을 사용하려고합니다. 내가 사용할 수

WebSocketsServlet.java : 내 Maven 프로젝트에 그리 즐 2.2을 사용하고 있습니다 웹 소켓 지원 이 명령으로 글래스 피시 :

클라이언트 코드는 app.js :

      websocket.onmessage = function (evt) { 
       alert('onmessage'); 
       var command = JSON.parse(evt.data);

내가 맥에서 크롬 18.0.1025.165이 테스트를하고있다. 서버 로그에서

Unexpected response code: 405 

이 오류가 없으며, 단지 내 "등록"(WebSocketsServlet) 로그가 표시됩니다 페이지 로딩에 나는이 오류가 발생합니다.

의견이 있으십니까?

미리 감사드립니다.

감사합니다.

Answer 1

GlassFish 3.1.2는 Grizzly 1.9.46을 사용합니다. Grizzly 2.x는 해당 버전의 GlassFish와 호환되지 않습니다. 1.9.4와 1.9의 1.9 버전을 3.1.2와 함께 사용해야합니다.
