WildFly Bootable Faces
Goals
The main goal was to take an out of the box JSF application (PrimeFaces Showcase) and run it in both a Java EE Server and in WildFly Bootable. Some addition goals:
- See how much we can improve performance by incorporating various optimization tricks for JSF applications
- See if WildFly Bootable is a viable option for JSF and migrating to Docker containers
Environment
- OpenJDK 11.0.10
- JBoss Wildfly 18.0.1
- WildFly Bootable 22.0
- JSF Production Mode
- Intel(R) Core(TM) i7-8750H CPU @2.21 GHz 16GB RAM
Optimizations
- Apache MyFaces (Bootable) instead of Jakarta Mojarra (Wildfly)
- PrimeFaces MOVE_SCRIPTS_TO_BOTTOM
- OmniFaces GzipResponseFilter
- OmniFaces CombinedResourceHandler
- PrimeFaces Extensions CombinedResourceHandler Helper
- PrimeFaces Extensions Optimizer
- jQuery Hide Page Until Complete
