Examples with Session javax.websocket.Session used on opensource projects

Example 16 with Session

use of javax.websocket.Session in project tomcat by apache.

the class TestWsWebSocketContainer method testSessionExpiryContainer.

@Test
public void testSessionExpiryContainer() throws Exception {
    Tomcat tomcat = getTomcatInstance();
