Further to my recent post about integrating Jersey and Spring, Christian Rivasseau shows how to integrate Jersey and Guice. As Paul notes in comments to that post, we plan to further simplify integration of template engines like Freemarker but its great to see the existing resource provider SPI working for another IoC framework.
The first early draft of JSR 311 is now available for review, download the spec and Javadoc here. As the name suggests this is an early draft and the specification is far from complete but it does provide an early look at the current API. You can also find a list of current issues here.
Please send feedback on the specification, Javadocs or current issues to users [at] jsr311.dev.java.net.
