Accessing Http Session In JAX-RS 2.0

JAX-RS 2.0 defines Filters and Interceptors. One can access the Http session by implementing a filter. For example:

import java.io.IOException;
import javax.inject.Named;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;

import javax.ws.rs.container.ContainerRequestContext;
import javax.ws.rs.container.ContainerRequestFilter;
import javax.ws.rs.core.Context;
import javax.ws.rs.ext.Provider;

@Named
@Provider
public class MyInterceptor implements ContainerRequestFilter {
    @Context
    private HttpServletRequest servletRequest;

    public void filter(ContainerRequestContext requestContext) throws IOException {
        
        HttpSession session = servletRequest.getSession(false);

        if (session != null) {
            // do stuff
        }
    }
}
