Goals

---

The main goal was to take an out of the box Faces (formerly JSF) application (PrimeFaces Showcase) and run it in both a Java EE Server and in Quarkus. Some addition goals:

• See how much we can improve performance by incorporating various optimization tricks for JSF applications
• See if Quarkus is a viable option for Faces and migrating to Docker containers

Environment

---

• OpenJDK 17.0.5
• JBoss Wildfly 18.0.1
• Quarkus 2.16.3.Final
• JSF Production Mode
• Intel(R) Core(TM) i7-8750H CPU @2.21 GHz 16GB RAM

Optimizations

---

• Apache MyFaces (Quarkus) instead of Jakarta Mojarra (Wildfly)
• PrimeFaces MOVE_SCRIPTS_TO_BOTTOM
• Quarkus Compression quarkus.http.enable-compression=true
• OmniFaces CombinedResourceHandler
• PrimeFaces Extensions CombinedResourceHandler Helper
• jQuery Hide Page Until Complete

Metrics

---

The following client and server metrics were captured while hitting the exact same page /datatable/crud.xhtml Using Incognito Mode and pressing CTRL+F5 so it forced the browser to load all resources from the server with nothing cached.

Development

---

To run the example in Dev mode:

git clone https://github.com/melloware/quarkus-faces
cd quarkus-faces
mvn quarkus:dev

Then open your web browser to http://localhost:8081/

Production

---

To run the example in HotSpot Production mode:

git clone https://github.com/melloware/quarkus-faces
cd quarkus-faces
mvn clean package
java -jar target/quarkus-app/quarkus-run.jar

Then open your web browser to http://localhost:8081/

Docker JVM

---

Builds a Docker image running as a standard JVM application.

mvn clean package -Ddocker
docker run -i --rm -p 8081:8081 melloware/quarkus-faces:latest

Docker Native

---

Builds a native Docker image running as a GraalVM (Mandrel) application.

mvn -Pnative
docker run -i --rm -p 8081:8081 melloware/quarkus-faces:${version}

Known Issues

---

We have a WIKI page where we are keeping track of known issues while developing with Quarkus/MyFaces/PrimeFaces. Please feel free to contribute to that page if you find anything you think others should know!
