It turns out that I was premature in concluding connections were
silently getting dropped.
I left the client application running for another quarter hour after it
stopped displaying message updates from the server. On shutting it
down, the server immediately recorded that the client had just

I have a desktop application that, using the org.glassfish.tyrus

Your idea of wrapping the interface returned by the registry was a stroke
of brilliance! And I'm pleased to say it was successful.
I'm now working to resolve another small hiccup. The IoC registry can be
configured to provide the service as either a singleton or a new instance
for each new
So I've converted the server endpoint from annotation-based to
programmatic, to get around the constraint of the @ServerEndpoint
annotation having to decorate a concrete class. The elements of this
annotation now occupy an implementation of ServerApplicationConfig:

Thanks Mark, you've made it clear that annotating the interface is not an
option.
Converting my server endpoint from annotation based to programmatic is not
a problem, nor is implementing ServerApplicationConfig to configure what
were previously @ServerEndpoint elements: value, encoders,
Hi Mark,
Looking at the Tapestry-IoC Registry code I notice that although it
constructs a (plastic) service proxy object, it does cast it to its
associated interface before making it available from the registry's
getService() method. So if I move the WebSocket annotations to my
interface as
Based on what you wrote regarding WebSocket annotations not following Java
inheritance, I imagine the below wouldn't work either.
public class MyServerEndpointConfig extends ServerEndpointConfig {
@Override
public Class getEndpointClass() {
return MyServiceInterface.class;
}

Hello,
Just a quick question with regard to extending
ServerEndpointConfig.Configurator to override Tomcat's default action of
instantiating the POJO class annotated with @ServerEndpoint on receiving a
WebSocket request. My reason for doing this is that my endpoint class
depends on IoC
Just to clarify, both services being injected the IoC way are developed by
me as part of the core program, so nothing sinister to be concerned about.
What would be useful to know is whether Tomcat instantiates classes
annotated with @ServerEndpoint inside or outside of the context of the WAR
app
Hi John,
The server-side endpoint is itself implemented as a Tapestry 'service',
allowing it to be injected into other application classes for pushing
messages out to connected clients. Whereas the service injected into the
endpoint class itself allows the endpoint to query this service when a
Hi team,
I have developed a web application using the Apache Tapestry framework and
deployed on Apache Tomcat. The application also supports WebSocket
connections with desktop clent applications. Following the advice of the
Tapestry community, I included the server-side endpoint within the

What I probably omitted to say is that localhost is likely to be
associated with many more domains than the Roller application alone. So
marrying the default host to Roller isn't likely to save me work.
Instead, I have added Alias elements to the Roller host for each blog
