Hi Sergey, Aki,
My application seems to work under Tomcat 8 with the following modifications:
1) Add @ServerEndpoint(value = "/services") on my service class (named
UserService.java)
2) Add a method into this class with the annotation @OnMessage like:
@OnMessage
public String hello(String message) {
return "Hello!";
}
3) Add the following dependency in my pom.xml
<dependency>
<groupId>javax.websocket</groupId>
<artifactId>javax.websocket-api</artifactId>
<version>1.0</version>
<scope>provided</scope>
</dependency>
With these changes, the sample almost works in both Tomcat version (7 and 8),
except that all websocket requests are routed to the method having @OnMessage
annotation :)
It seems it needs some configurations again :)
Hope this will help.
Best regards,
Anthony

Hi Sergey,
Thanks very much, I deployed on Tomcat 7 and it works fine.
I will investigate deeper to try to understand what's going on with Tomcat 8...
Regards,
Anthony

Hi Anthony
Sorry it is my fault, I looked at the master source, not realizing 3.1.7
uses a different Atmosphere version (2.3.7).
I've run a websocket_web demo with a Tomcat 7 plugin and it works fine
for me. Can you confirm please this demo also works for you ?
Thanks, Sergey
