Eclipse javax.websocket import not resolved
<p>I'm new to Java development (using it for speeding up my real-time game server, coming from Python).</p>

<p>I'm trying to add some basic Java server-side websockets, and added the simplest example code I found (from <a href="https://stackoverflow.com/questions/4278456/websockets-production-ready-server-in-java">WebSockets production ready server in Java?</a>).</p>

<p>I'm importing the following:</p>

<p>My problem is, eclipse is telling me that the <strong>import "javax.websocket" cannot be resolved</strong>. Where I can add the "javax" module? I don't understand the complicated interface fully yet, thanks a lot for any help! (I've got the latest eclipse, with Java 8 installed on Mac os X 10.11 latest)</p>
