Add gem "webrick" to the Gemfile in your website. Than run bundle install

At this point you can run bundle exec jekyll serve

I can run the application in IIS Express Development Environment without issue. When I switch to the IIS Express Production environment or deploy to an IIS host, my index referenced files cannot be read showing a browser error:

QUESTION

Registration of dynamic websocket at application initialization time and at runtime has different endpoints exposed

Asked 2021-Jun-14 at 21:32

I am trying to register websocket dynamically.For instance, i have registered '/sampleEndpoint' at runtime so ServerWebSocketContainer will register it and start publishing data on that endpoint. But now if i do the same process during application initialization time in PostConstruct than i am unable to connect to '/sampleEndpoint' but have to append '/websocket' at the end so url become '/sampleEndpoint/websocket' when connecting from client side. Why we are getting different endpoints at different situations?

I have attached github url to the code.

ANSWER

Answered 2021-Jun-14 at 21:32

Well, that's how that SockJS option works: https://docs.spring.io/spring-framework/docs/current/reference/html/web.html#websocket-fallback.

If you client is not SockJS, then you have to add that /websocket sub-path.

Not sure though why it doesn't work for dynamically registered endpoints...

In the case of @PostConstruct it is not dynamic: we still do the stuff within configuration phase of the application context, so it is able to add our endpoint into a static HandlerMapping. The dynamic nature is applied a bit later, when all the @PostConstruct have done their logic. You don't need to start that flow registration manually though since the auto-startup phase has not passed yet withing @PostConstruct handling.

Re. IntegrationDynamicWebSocketHandlerMapping: it sounds more like a bug and I need to investigate more. I guess you still use there that SockJS option and it has to be applied for dynamic endpoint as well.

Thank you for your patience! I'll investigate and fix it ASAP.

The fix is here: https://github.com/spring-projects/spring-integration/pull/3581.

reactjs useState and useEffect hooks not re-rendering after array data change for data received via websocket

Asked 2021-Jun-14 at 16:52

I am building an app with reactjs tha needs to be real-time and I am using Rails Actioncable as a wrapper around websocket.

I can receive data via websocket after a record is created or updated and when I do console log to see what is contained in the posts array created with useHook but updated via webhook. It seems the post array is updated correctly using the code shown below. However react does not re-render the web page hence the use does not see that updated record.

ANSWER

Answered 2021-Jun-14 at 16:52

I fixed the issue with react not re-rendering when the state is updated via webhook. The primary problem was this line:

const [posts, setPosts] = useState(props.posts || []);

I changed that line to this:

const [posts, setPosts] = useState([]);

With that change this two approached updated the state with a re-render & broadcast of the state change via websockets to other open tabs.

Jersey requires an appropriate container module to deploy the REST application. You added jersey-container-jdk-http, which works with a JDK Http Server (cf. documentation).

What you need instead is the jersey-container-servlet module (cf. documentation), which works in every Servlet 3.x environment. Therefore you need to add this dependency:

Laravel Websockets reverse proxy port Nginx config to Apache virtual host
