リソースが動的にロードされる OSGI を使用して JAX-RS アプリケーションを開発しています。このためには、プログラムで ServletContainer を登録する必要があります。その後、メソッド ServletContainer.reload (ResourceConfig) を呼び出すことができます。PAX-WEB 3.0.2 と Jersey 2.4 を使用して、サーブレット 3.x をサポートする OSGI 環境で実行しています。問題は、Server Sent Event を実装するリソースにアクセスしたいときに、Jersey が Servlet 2.x で実行されるため、非同期をサポートしないというエラーを発生させることです。
ここで例外：

ServletContainer をさまざまな方法で登録しようとしましたが、何も機能せず、Jersey の登録と設定に問題があると思います。Server Sent Event ベースの非同期サーブレットを記録し、すべてがうまくいったからです。
コード例:
ServletContainer container = new ServletContainer();
...
...
webContainerRef = bc.getServiceReference(WebContainer.class);
started = webContainerRef != null;
if (started) {
final WebContainer webContainer = (WebContainer) bc
.getService(webContainerRef);
if (webContainer != null) {
// create a default context to share between registrations
final HttpContext httpContext = webContainer
.createDefaultHttpContext();
// set a session timeout of 10 minutes
webContainer.setSessionTimeout(10, httpContext);
// register the hello world servlet for filtering with url
// pattern
final Dictionary<String, Object> initParamsServlet = new Hashtable<String, Object>();
initParamsServlet.put("javax.ws.rs.Application", "com.workingflows.osgi.jaxrs.samples.conf.MyJaxApp");
webContainer.registerServlet(
container, // registered
new String[]{"/rest/*"}, // url patterns
initParamsServlet, // init params
1,
true,
httpContext // http context
);
webContainer.registerServlet(
(HttpServlet) new SseServlet(), // registered
new String[]{"/servlet/sse"}, // url patterns
initParamsServlet, // init params
1,
true,
httpContext // http context
);
}
}
