I'm happy to be in any role needed to be filled :) I think this is a
fantastic idea.

Hi,
I’ve opened a proposal[1] to be able to build and run WildFly application
from JBang[2]
The goal of this proposal is to be able to quickly *prototype* WildFly
applications from a single .java file with no need to set up a Maven
project, configure any plugins, etc.
TL;DR copy the file myapp.java:
///usr/bin/env jbang "$0" "$@" ; exit $?//JAVA 17+//DEPS
org.wildfly.bom:wildfly-expansion:${wildfly.version:35.0.1.Final}@pom)//DEPS
org.wildfly.glow:wildfly-glow:1.3.2.Final//DEPS jakarta.ws.rs:jakarta.ws.rs-api//DEPS
jakarta.enterprise:jakarta.enterprise.cdi-api
import jakarta.enterprise.context.ApplicationScoped;import jakarta.ws.rs.GET;import
jakarta.ws.rs.Path;import jakarta.ws.rs.ApplicationPath;import
jakarta.ws.rs.core.Application;
@ApplicationPath("/")public class myapp extends Application {
@Path("/hello")
@ApplicationScoped
public static class Hello {
@GET
public String sayHello() {
return "Hello, WildFly!";
}
}
}
You would then run `jbang run my app.java` et voila! You have your code
running in a WildFly server with all required capabilities as a Web archive.
The implementation is well under way and only impacts the WildFly Glow
project.
The PR[3] for WildFly glow has also some documentation with working
examples to prototype a simple Web application, a MicroProfile application,
and a Chat bot based on an Ollama model.
This is an experimental feature.
I’m looking for volunteers to provide an outside perspective on this
feature.
If you are interested by this proposal, please have a look at the
proposal, the PR in Glow
Thanks,
Jeff
