Summary: Launcher API
Issue Type: Feature Request
Security Level: Public (Everyone can see)
Reporter: Brian Stansberry
1) The AS should have some sort of API for launching our processes so tools that want a
process have a clear contract instead of having to guess at what's relevant in our
2) We want the main class in our process launch to be what's invoked by java -jar
jboss-modules.jar. We don't want java -jar jboss-as-launcher.jar which does some stuff
and then calls org.jboss.modules.Main.
3) JBoss Modules itself shouldn't have a lot of the stuff in it that's relevant to
an AS launcher API, because many of those things are not relevant to JBoss Modules in a
What we could do though is provide a launcher lib that isn't involved at all in our
normal boot. Something that would only be used by tools that want to launch a separate,
i.e. non-embedded, AS process.
So, some sort of stable configuration API and then a simple
Basically, a utility that does the ProcessBuilder stuff that everybody is doing themselves
Eclipse-based tools like JBDS use Eclipse APIs for launch and would not use the above
So, besides that launch method, look into adding some methods to give the necessary inputs
to the Eclipse API be useful. So Eclipse-based tools don't ask it for the process but
can still get a standard launch configuration.
I'd only want to do that if those methods would return something generally
understandable, but a String or List<String> for classpath, List<String>s for
vm/program args, some representation that "-jar jboss-modules.jar" is the way to
get the main class -- those all seem generic enough.
Any "which VM" stuff is consider out of scope; choosing the VM is the
responsibility of the tool. Options that are not universally supported across VMs and are
those a function of VM choice, like whether to use -server, are also out of scope.
