Runnable GlassFish Embedded - run Jakarta EE apps from command line, will be in 7.0.18

[OndroMih]

I've recently worked on this new feature in GlassFish. It allows running GlassFish Embedded from command line: java -jar glassfish-embedded.jar. This is already merged and will be available in the next version of GlassFish 7.0.18.

Demo:

Runnable.GlassFish.Embedded.demo.mp4

Supports configuration via command line arguments and/or config files in the current directory:

• set HTTP port
• deploy applications passed as arguments
• run arbitrary AsAdmin commands at boot

All GlassFish Embedded flavors are supported:

• Standalone glassfish-embedded-all.jar, glassfish-embedded-web.jar, and glassfish-embedded-nucleus.jar
• glassfish-embedded-static-shell.jar in the GlassFish Server installation

Includes fixes that made GlassFish Embedded Web usable. Includes fixes to the Static shell to make it equal to standalone GlassFish Embedded JAR files.

java -jar glassfish-embedded.jar --help prints the following info: glassfish.man.txt

The full documentation can be previewed here: https://glassfish.org/docs/SNAPSHOT/embedded-server-guide.html#running-from-command-line.

The pull request with the code changes: #25146

Video missing audio, is it intentional?

[OndroMih]

Correct, no audio. It’s just a quick demo.

What is glassfish-embedded-nucleus.jar? I can understand all and web. is it core profile?

[OndroMih]

Good question. The nucleus distribution is something that existed for a long time, at least since GlassFish 3. It has nothing to do with Jakarta EE Core profile. It’s a barebone distribution, I think comparable to a servlet container like Tomcat, and it was designed to allow adding individual Java EE components according to what applications need. However, it’s not documented how to do this.

Thanks for the clarification. is there any demand for gf embedded core profile?

That would be helpful.
