Hello everyone,
I’m writing to you with a request about Vaadin 8 framework and Equinox OSGi.
I have tried to make a simple Vaadin application without any Maven dependencies in Eclipse.
(https://github.com/sirreaver/vaadin.test)
I have downloaded Vaadin 8.8.2 with Jetty 9.4.18.v20190429 (also tried with 9.3.24).
I have 4 classes (this was taken from lunifera example which Vaadin also use in its part of documentation:
https://github.com/lunifera/lunifera-vaadin-examples/tree/master/org.lunifera.example.vaadin.osgi
Problem starts, when I try to use Push. With settings:
@Push(value = PushMode.AUTOMATIC, transport = Transport.WEBSOCKET)
and over servlet class
@WebServlet(asyncSupported = true)
session expires immediately.
I know that in this forum is quite a lot of topics to this but setting LONG.POLLING is not a solution for me.
When I tried to run Vaadin application with Maven I can see that Atmosphere container is set to JSR356AsyncSupport. But in my case was set to Jetty9AsyncSupportWithWebSocket.
After some googling and also on Jetty official site there is written which bundles I should use to activate Servlet 3.0+ So I have tried to use them but then I got problem with:
Real error: Unable to configure jsr356 at that stage. ServerContainer is null";;"Exception: java.lang.IllegalStateException: Unable to configure jsr356 at that stage. ServerContainer is null.
My question is if somebody could be so nice and revise little bit my project settings in Eclipse with Equinox? From what I have found it may be some dependency on start level of bundles or even used ServiceComponent class from lunifera should not be used anymore and used some different way?
Here is list of activated bundles:
(I bet I do not need some of them, but I was trying some combinations to make JSR container available)
