            How can Bloc listen to stream and emit state

            In my flutter app, I use flutter_bloc for state management.

            The bloc in question uses a repository. The repository subscribes to a websocket, and new data is added to a stream.

            IntelliJ - Invalid source release: 17
            Asked 2022-Mar-17 at 13:46

            I've created a new Java project in IntelliJ with Gradle that uses Java 17. When running my app it has the error Cause: error: invalid source release: 17.

            My Settings

            I've installed openjdk-17 through IntelliJ and set it as my Project SDK.

            The Project language level has been set to 17 - Sealed types, always-strict floating-point semantics.

            In Modules -> Sources I've set the Language level to Project default (17 - Sealed types, always strict floating-point semantics).

            In Modules -> Dependencies I've set the Module SDK to Project SDK openjdk-17.

            In Settings -> Build, Execution, Deployment -> Compiler -> Java Compiler I've set the Project bytecode version to 17.

            The message typically entails that your JAVA_HOME environment variable points to a different Java version.

            Here are the steps to follow:

            • Close IntelliJ IDEA
            • Open a terminal window and check your JAVA_HOME variable value:
              • *nix system: echo $JAVA_HOME
              • Windows system: echo %JAVA_HOME%
            • The JAVA_HOME path should be pointing to a different path, then set it to the openjdk-17 path:
              • *nix system: export JAVA_HOME=/path/to/openjdk-17
              • Windows system: set JAVA_HOME=path\to\openjdk-17
            • Open your project again in IntelliJ IDEA
            • Make sure to set both source and target compatibility versions (not only the sourceCompatibility)

            You should be able to build your project.

            EDIT: Gradle Toolchain

            You may need also to instruct Gradle to use a different JVM than the one it uses itself by setting the Java plugin toolchain to your target version:

            NestJS GraphQL subscriptions not working with `graphql-ws`

            At the time of release of Apollo Server 3, the protocol used in the graphql-ws library is not yet supported by GraphQL Playground or Apollo Explorer.

            see here

            It's only advisable to use graphql-ws if interacting with subscriptions via playground is not of much use to you and you're okay interacting with subscriptions solely from your own client that has been setup to use graphql-ws.

            WebSocket not working when trying to send generated answer by keras

            I am implementing a simple chatbot using keras and WebSockets. I now have a model that can make a prediction about the user input and send the according answer.

            When I do it through command line it works fine, however when I try to send the answer through my WebSocket, the WebSocket doesn't even start anymore.

            There is no problem with your websocket route. Could you please share how you are triggering this route? Websocket is a different protocol and I'm suspecting that you are using a HTTP client to test websocket. For example in Postman:

            Postman New Screen

            HTTP requests are different than websocket requests. So, you should use appropriate client to test websocket.

            How to give certificate to Java Websocket?
            Asked 2022-Jan-20 at 10:33

            Forgive me for the newb question, but I am confused and obviously not understanding the fundamentals or explanations of how to use a Websocket server hosted over HTTPS. Everything I find online leads me to have more questions than answers.

            I have a Websocket server hosted on my HTTPS website using Java code.

            This is my WebsocketServer.java file:



            Answered 2022-Jan-13 at 14:50

            Keep it easy.
            Certs inside your application are complex - they are hard to manage and you will get problems to run your application in a modern cloud environment (start new environments, renew certs, scale your application, ...).

            Simple conclusion: Dont implement any certs.

            How-to get encrypted connections?

            As Mike already pointed out in the comments: WebSockets are just upgraded HTTP(S) connections. A normal webserver (nginx, apache) takes care about the certs. It can be done in kubernetes (as ingress-controller) or with a "bare-metal" webserver.
            Both of them should act as a reverse-proxy. This means: Your java-application doesn't know anything about certs. It has just unencrypted connections - like in your code on port 6868.
            But the client will not use this port. 6868 is only internally reachable.

            The client will call your reverse-proxy at the normal HTTPS port (=443). The reverse-proxy will forward the connection to your java-application.
