How to have websockets with multiple context using same port (using jetty 8)

I trying to implement websocket server, requirement is to have multiple context on same port i.e.

ws://ip:8989/provider1
ws://ip:8989/provider2

should provide two different connection but on same port.

I had followed old article How do I create an embedded WebSocket server Jetty 9? to create context handler.

I tried below code to create two seperate context

ContextHandler context = new ContextHandler();
context.setContextPath("/provider1");
context.setHandler(wsHandler);
server.addHandler(context);
ContextHandler context = new ContextHandler();
context.setContextPath("/provider2");
context.setHandler(wsHandler);
server.addHandler(context);
server.start();
server.join();

But I am getting data only on 2nd context. Is this correct implementation?

Even if i made it work I have final requirement where i have to open/create context on-the-fly i.e. after starting server with first context.

Can somebody explain to how to achieve these requirement using single port?

Your problem is that you only can have one handler in Jetty 8 Server Class becouse, there is not addHandler.

The handlers are a wrapper class and they can be configured like a matryoshka doll. This is create a handler collection (HandlerCollection) and put here both context handler. This class has addHandler method

The code is the following

// Collection 
HandlerCollection hc = new HandlerCollection();

// First context
ContextHandler context = new ContextHandler();
context.setContextPath("/provider1");
context.setHandler(wsHandler);
hc.addHandler(context)

// Second context
ContextHandler context2 = new ContextHandler();
context2.setContextPath("/provider2");
context2.setHandler(wsHandler2);
hc.addHandler(context2)


server.setHandler(hc);
server.start();
server.join();
