Re: [jetty-users] Jetty 10 websocket API changes

Thank you very much for this Greg. No problem for us to wait a bit longer before moving to Jetty 10 considering 9.4 is serving us as well as it is.

Cheers,

Sillvio

Silvio,

yes the jetty websocket API has been significantly revisited in jetty-10.   We believe that we have added significant improvements as a result and have been waiting for the major release to make such a breaking change.

We definitely will continue to support our API going forward, due to deficiencies and complications of the JSR API.  So if your use-case is not already supported, then we will definitely look to see if we can.  Lachlan Roberts is the lead developer of websocket now and hopefully will get back to you with pointers to servlet based upgrade (which I'm 99% sure is supported).

cheers

Some time ago I extended our embedded Jetty (9.4.36) based server
application to support websockets using the Jetty websocket API. At this
time we want to revisit our previously successful efforts making the
application compatible with Jetty 10. But it seems the websocket API has
changed quite significantly and many of the classes in
org.eclipse.jetty.websocket.servlet and org.eclipse.jetty.websocket.api
(notably WebSocketServletFactory, WebSocketCreator,
ServletUpgradeRequest and ServletUpgradeResponse) appear to be missing
or have been moved/renamed. So now we use the websocket API it appears
porting to Jetty 10 has become much more difficult, let alone managing a
code-base that allows us to swap one in for the other.

We picked the Jetty websocket API since it allows us to handle the
request upgrade at the Servlet level (inside the service method) while
the javax.websocket API upgrades to websockets at the context level and
is therefore of nu use to us. I hope this is still possible in the
revised Jetty websocket API but can not find any documentation about how
to rewrite 9.4.x based code to the new 10.x version.

I can live with not being able to switch back to Jetty 9 without
recompiling.

Can anyone give me some pointers?

Kind regards,

Silvio
