Demo Web Socket

Objectives

A simple Java Websocket Server and Client with a minimal javascript web client.

Building

mvn clean package

Running

Java

By default the server and the client bind on localhost:8025

Run the server

java -jar Server/target/Server-2.0-jar-with-dependencies.jar

Run one or mode clients

java -jar JavaClient/target/JavaClient-2.0-jar-with-dependencies.jar

Run the web client in a jetty server

mvn --projects WebClient jetty:run-war

Docker

Launch the server with a name and mapped port.

docker run \
        --rm -it \
        -p 8025:8025 \
        --name wsserver \
        docker.io/brunoe/demowebsocket.server:develop

Launch one or more client linked to the server.

docker run \
        --rm -it \
        --link wsserver \
        --env JAVA_OPTS="-Dfr.univtln.bruno.demo.websocket.server.ip=wsserver" \
        docker.io/brunoe/demowebsocket.javaclient:develop

Launch one or more web clients and open http://localhost:8080 (or map another port). Warning, the client is Javascript executed in the browser, so the web socket server must be reachable from there and not from the container (so it needs to be mapped to an host port).

docker run \
        --link wsserver \
        --rm \
        -p 8080:8080 \
        brunoe/demowebsocket.webclient:develop
