Stanley Ho's Blog: June 2007 Archive

This snapshot currently covers the core features (see Andreas's blog) described in the updated specification in JSR 277, and the reflective APIs defined in JSR 294. If you are wondering how the module system works internally and want to take an early look or even contribute, I encourage you to check out the Modules project.

Besides the snapshot, we have also made other goodies available:

A Getting started guide that helps you understand the source structure of the project.
A few samples that show you how to create and use simple modules.
Documentations that describes some of the tools and functionalities available, including

how to execute modules from repositories through the Java launcher.
jam tool - think of it as the jar tool for the world of modules.
visibility policy - a mechanism that allows you to pick and choose which modules to use in a specific deployment when there could be zillion of modules available from the repositories.

A NetBeans project (requires NetBeans 6.0 M9 or later) for easy browsing and editing of the relevant source files from the IDE.

Obviously, this is just the beginning. You should expect the snapshot will be updated periodically and new goodies will be posted going forwards, as we evolve the implementation and add many functionalities in the coming months.

If you are interested in discussing the implementation in the Modules project, we have made two discussion lists available for the Java community to join:

modules-dev@openjdk.java.net: Technical discussion about the implementation of the Modules project
modules-discuss@openjdk.java.net: General discussion of the Modules project and how to use modules

If you want to discuss the Modules project with its developers, or how to use JSR 277 and JSR 294, be a subscriber today!

JSR 277 on Google Video

A few weeks ago, Michal Cierniak (Michal has been spending part of his 20% time as a contributing member in the expert group) and I presented the Java Module System (JSR 277) as part of the Advanced Topics in Programming Languages Series at Google. This presentation was based on the current design described in the updated JSR 277 specification, and the video is now available online here. You could also google the video directly using "JSR 277" from the Google Video site. If you want to learn more about the current design of JSR 277, this would be a good place to start!

More on updating the JSR 277 specification ...

Since the early draft was available, I have been discussing the feedbacks we received from the community with the expert group and incorporating their inputs into an updated specification. This updated specification has evolved significantly from the early draft, and this is also what the recent discussions in the EG mailing list based on. To help those of you who are observers of the EG mailing list to follow the discussions more easily, I am going to make the updated specification (and possibly other strawmans as well) publicly available soon. Stay tuned!
