WebSockets in Tomcat and eclipse

Hi Experts,

I'm trying to add the following sample to my project:
https://tyrus.java.net/documentation/1.11/index/deployment.html

Although my build path points to:
C:\Program Files\Apache Software Foundation\Tomcat 7.0\lib\websocket-api.jar,

Eclipse still has red lines under all my imports at the top of the class (and ServerEndpoint)
import javax.websocket.OnClose;
import javax.websocket.OnMessage;
import javax.websocket.OnOpen;
import javax.websocket.Session;
import javax.websocket.server.ServerEndpoint;

@ServerEndpoint("/PushNotifications")

Not sure why eclipse is not recognizing these, my colleague did the same thing and doesn't have this issue.

Any idea why?

Many thanks,
Mike

Check whether the build path entry has taken effect. In the "Project Explorer", under your project it should list (in addition to source folders, etc) all the libraries that are part of it, including the "JRE System Library". Does websocket-api.jar show up here?

If it does show up there, maybe try doing a "Project" -> "Clean" or restarting Eclipse to get it to properly recognise the imports in your source file.

If it does NOT show up, double check your build path settings. Maybe post a screenshot of the build path page for us to look over. Also, check out the ".classpath" file that should be in the root of your project directories, and the websocket-api.jar should be listed in there. Maybe post the contents of that file here too for us to look at.
