JAX-RS 2.1 Server Sent Events example

JAX-RS 2.1 Server Sent Events example based on YouTube video by Adam Bien - https://www.youtube.com/watch?time_continue=8&v=qQLVCgmiMgQ

SSE for JAX-RS is defined in https://www.jcp.org/en/jsr/detail?id=370

Running

mvn clean package
cp target/ee8-sample-sse.war ${PATH_TO_SERVER}

curl -i http://localhost:8080/ee8-sample-sse/resources/beats  

Another use-case is to run the project directly in IDE - e.g. NetBeans IDE

Where do I get those servers?

GlassFish 5 - https://javaee.github.io/glassfish/download

WildFly 10.1 + RESTEasy master - not yet released, you have to build it:

git clone https://github.com/resteasy/Resteasy.git
cd Resteasy
mvn clean package -DskipTests -Denforcer.skip=true -Dcheckstyle.skip=true
ls testsuite/integration-tests/target/test-server/wildfly-10.1.0.Final

WildFly & RESTEasy - Accept header

When running against WildFly 10.1 + RESTEasy master, Accept header was needed for some time

curl -i -H "Accept: text/event-stream" http://localhost:8080/ee8-sample-sse/resources/beats

• Discussed in http://lists.jboss.org/pipermail/resteasy-dev/2017-October/000478.html
• Issue tracked in https://issues.jboss.org/browse/RESTEASY-1733

WildFly & RESTEasy - Filters issue

curl -vvv http://localhost:8080/ee8-sample-sse/resources/foo
## vs.
curl -vvv -i http://localhost:8080/ee8-sample-sse/resources/beats

Response for beats endpoint is without CORS filter headers.
