            Getting 404 while trying to access endpoints using Jersey 3 and Tomcat 10
            Asked 2021-Jun-14 at 13:32

            Been trying for days to fix this problem. Just trying to recreate a simple "Hello World" REST api with Jersey 3 and Tomcat 10 in maven. After creating the WAR file of the project I can access the index.jsp (created by default when I created the project) but when I try to access the "/helloworld" endpoint I get error 404. Here's my code:

            Answered 2021-Jun-14 at 13:32

            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:

            How to always get the latest version of an specific dependency in maven 3.x?
            Asked 2021-Apr-10 at 10:39

            I have a maven project with large pom file, I want one of my dependencies to be always the latest version which is deployed to our local antifactory server.

            the name of this dependency is "WebInfra" and I use maven 3.x so the "LATEST" keyword is not working for me.

            I'll put the pom file here and I'll be happy to find a solution for this problem. I need other dependencies to stay in their fixed version and only this dependency should upgraded to the latest version each time I call mvn clean deploy on it. I see "Versions Maven Plugin" and set its includes and excludes but not working for me : I have webinfra-1.jar and then I deployed webinfra-2.0-SNAPSHOT into artifactory server but when I run mvn versions:use-latest-versions nothing happens. I expect my pom change into version 2.0-snapshot. What's going wrong here ?

            Answered 2021-Apr-10 at 10:39

            You need to have two separate runs of Maven:

            1. Update the version with the versions maven plugin on command line.
            2. Run something like mvn clean verify to build the project.

            You cannot change the version while building the project.

            BTW: You configured Java 5. Are you really sure you want this?

            You have most likely forgotten to deploy your API (Routes -> Actions -> Deploy API). WebSocket APIs still use the old console which does not have auto deploy.

            Having the same class name in multiple locations on your classpath is a bad idea.

            This is the most common form of unstable operation on Java there is!

            The classloaders in Java have no guarantee of load order behavior if the same class is present in multiple locations within the classloader.

            In one run you might accidentally load the classes in the order you intend, and have it run properly, then at a future date you run the same program and the load order is different, now you are running with a different class version and you have unexpected behavior.

            The only way to fix this is to clean up your classloader and ensure that you only have 1 version of the class you intend to use.

            This is what Jetty is telling you.

            As for this specific one, javax.websocket-api and javax.websocket-client-api, you want to exclude javax.websocket-client-api at the gradle level, as all of the websocket client classes are also present in the javax.websocket-api.

            The javax.websocket-client-api jar is only intended for projects that only use the javax.websocket Client, without a javax.websocket Server.

            Following the suggestion of joakim-erdfelt I have modified my gradle.build and this prevent the problem:

            Trying to understand lambda function that is part of the logic of api gateway websockets connection
            Asked 2020-Nov-17 at 14:12

            TLDR: How do i send a short payload from a mqtt request to aws iot to aws lambda that has a open connection via apigateway to an electron app running locally in linux.

            I have a esp8266 with the following code as the init.js This code succesfully sends it's message to aws iot, with a rule set to trigger a lambda called sendmessage. Now this sendmessage lambda is connected via websockets to a Electon app locally on my linux machine. I am able to send messages from the Electron app via websockets to api gateway wss url. I followed this example here which sets up all the websockets with api gateway and aws lambdas (one being the sendmessage lambda).

            ANSWER

            Answered 2020-Nov-17 at 04:59

            It seems like you're setting 1 lambda to handle 2 trigger sources, one is IoT service, the other is API Gateway Websocket. Since you use 1 lambda, you have to handle cases when the request is came from sources:

            1. While event.requestContext is available when the request is triggered from API Gateway, it is not available when the request is triggered from IoT service (check the IoT event object here https://docs.aws.amazon.com/lambda/latest/dg/services-iotevents.html). So the error you faced (which is Cannot read property 'domainName' of undefined") is about that. You should turn off the lambda trigger from IoT service or handle the request when it comes from IoT Service.
            2. I'm not sure about the forbidden error but it is more like you sent unstructured message to API gateway WS, it should be connection.send(JSON.stringify({ action: "sendmessage", data: "hello world" })); instead of connection.send("hello world");

            Edited based on post update:

            I know ws is there because if I console it it returns a big object with a bunch of functions

            Lambda function is not really a server, it is an instance Node environment (that's why it is called FUNCTION), Lambda function doesn't work as the way you think normal Nodejs app does, its container (node environment) usually is halted (or freeze) whenever its job is done so you cannot keep its container alive like a normal server. That's the reason while you can console log the Websocket object, you cannot keep it alive, the NodeJS container was already halted whenever you return/response.

            Since you cannot use the Websocket object to open WS connection in Lambda, Amazon offers a way to do that via API Gateway. The way we work with API Gateway Websocket is different than the normal server does too, it would be something like:

            • User -> request to API Gateway to connect to websocket -> call Lambda 1 (onconnect function)
            • User -> request to API Gateway to send message over Websocket -> call Lambda 2 (sendmessage function)
            • User -> request to API Gateway to close connection -> call Lambda 3 (ondisconnect function)

            3 settings above is configured in API Gateway (https://docs.aws.amazon.com/apigateway/latest/developerguide/apigateway-websocket-api-integrations.html), logic of 3 functions onconnect, sendmessage, ondisconnect can be handled in 1 lambda or 3 lambda functions depending on the way we design, I check your 3 lambda functions and it looks okay.

            I see that you want to use IoT but I'm not sure why. You should test your Websocket API first without anything related to IoT. It would be better if you can tell what you want to achieve here since IoT works more like a publish/subscribe/messaging channel and I don't think it's necessary to use it here.
