Simplest possible working cometd java client -


i've been trying simple cometd java server , client setup, using cometd version 3.1.2 , jetty 9.4.6.v20170531, using code cometd's documentation.

httpclient httpclient = new httpclient(); httpclient.start();  map<string, object> options = new hashmap<string, object>(); clienttransport transport = new longpollingtransport(options, httpclient); bayeuxclient client = new bayeuxclient("http://localhost:9025/mycontext/cometd/", transport);  client.handshake(); boolean handshaken = client.waitfor(5000, bayeuxclient.state.connected); if (handshaken) {   system.out.println("yes");   // here handshake successful } system.out.println("done");

the server setup i'm interested in, , spring injected embedded jetty server cometd servlet. no matter i've tried client not handshake. able prove server correctly setup , available send request via postman...

[{     "version": "1.0",     "minimumversion": "0.9",     "channel": "/meta/handshake",     "supportedconnectiontypes": [         "long-polling",          "callback-polling"     ],     "advice": {         "timeout": 60000,         "interval": 0     },     "id": "1" }]

...which returns 200...

[     {         "minimumversion": "1.0",         "clientid": "11jlmrekgqnu9v1i4w1b8rgiq3c",         "supportedconnectiontypes": [             "long-polling",             "websocket"         ],         "advice": {             "interval": 0,             "timeout": 60000,             "reconnect": "retry"         },         "channel": "/meta/handshake",         "id": "1",         "version": "1.0",         "successful": true     } ]

...so, clearly, server setup fine. i've set break points , used tcpflow traffic , can tell, simplest possible client using cometd's own libraries starter documentation never sends request @ all. no tcp traffic. know i'm missing? appreciated.

you must have else going on.

your code correct, , cometd test suite uses code hundreds of tests , it's working fine.

please have read @ troubleshooting section of cometd documentation.

as suggestion, enable debug logging level org.cometd category, , @ logs obtain: should evident problem is.

feel free attach logs issue @ cometd issue tracker if still have problems.
