The Netbeans guys want feedback on Netbeans 5.0, which is essentially feature-complete. Download it, give it a spin and let them know what you think. I'm downloading it right now.

Alejandro announces a new release of ROME (the Java-based feedparser that powers Roller's built-in aggregator) is available. ROME v0.7 BETA is primarily a bug fix release. Judging from the mailing-list, I'd say Atom 1.0 format support is probably coming in the next release.

When I found out about the big Roller installation inside IBM, I urged the IBM guys to move to Roller 1.0 and to help out with Roller development. Well now, looks like that's happening (tho they're probably going to skip straight to Roller 2.0). IBM blogger Elias Torres has been participating on the Roller list, submitting patches (for Apache Derby and IBM DB2 support) and showing great interest in further contributions. So, I just want to say: thanks Elias!

Wondering what's going on with Roller and Derby? Elias has submitted a couple of patches, but Derby support is not quite there yet. I think there's a pretty good chance we'll be able to work out the issues in the 2.0 timeframe. One of the reasons I upgraded Roller to use Hibernate3 yesterday (the 2.X to 3.0 migration was quite a pain, BTW) was to help Elias along. He may have to fine-tune Hibernate's Derby and he'd much rather do that with a modern version of Hibernate (we were on Hibernate 2.1.4 before).

Alexis Moussine-Pouchkine links to XULFaces, a JSF renderkit for XUL. So, can you really develop a webapp, switch renderkits and have it look like those screenshots? Gotta admit, that's pretty cool.

There have been a number of somewhat confusing announcements and threads regarding the open source licenses that are popular among Java developers: APL, LGPL, MPL and CDDL. Here's my take on a couple of those items.

Open office goes LGPL

The first announcement regards LGPL and SISSL. Sun has retired the SISSL and the Sun-sponsored Open Office project will be making all subsequent releases under the LGPL license. This doesn't mean that Sun is moving en masse to LGPL as at least one Java blogger seems to think. It just means that the OpenOffice folks decided that LGPL is the best license for their product.

JSF goes CDDL

The next announcement regards CDDL and JSF. Sun has released its Java ServerFaces implementation under the CDDL. Some Java sites covered this as news, but I don't think it is all that newsworthy. Sun had already released its J2EE implementation Glassfish under CDDL and J2EE now includes JSF, so most license savvy folks probably already assumed that JSF was under CDDL.

Apache and the LGPL

And finally, we come to the touchy topic of Apache and the LGPL. Apache is close to deciding a policy to define how LGPL components may be used in official Apache releases. Does this mean that Apache projects can now use and ship LGPL components. No, not yet. Cliff Schmidt announced the <a href= "http://mail-archives.apache.org/mod_mbox/www-legal-discuss/200508.mbox/%3c96D75844-B15A-45E3-BF8D-5CF4517A09E2@apache.org%3e">proposed policy and that policy was to be voted on by the Apache board on Aug. 17, but I've heard no news of this.

In case you're wondering what this might mean to Roller, the proposed policy allowed Apache projects to depend on third-party LGPL components but not to ship them. For Roller, that would mean that we can keep on using Hibernate, but we'd have to ask people to download the Hibernate jars separately from Roller. That's unpleasant, but it's not too bad, I guess. If you read the email thread that Cliff's email started you'll see that some folks would like to allow Apache projects to ship third-party LGPL components, but not to have hard dependencies on them. For Roller, that's actually worse. We'd have to support an alternative non-Hibernate implementation of the Roller backend. We've been there and done that (i.e. supported both a Hibernate and Castor/JDO backend) and it was not an experience that I'd like to repeat. I wonder what happened in that Aug. 17 board meeting.

I'd also hoped to answer the question posed by Geert Bevin on The Server Side: What's the best developer-friendly open-source license for Java products, but that'll have to wait for a later post.

It's that time again folks. Come on down to Cafe Cyclo and join us. Josh has the details.

As I promised at the start of the week, I've put together an easy to install "early access" build of Roller 2.0. The build is a standalone bundle that includes pre-configured Tomcat app server, HSQL-DB database and Roller packages. You should be able to get up and running by simply unzipping the package and running the startup script.

You can get the build here: roller20ea-demo.tar.gz

The purpose of this release is 1) to get feedback on the new Roller UI and group blogging features and 2) to allow folks to help out with testing. If you have feedback on the UI and new features, subscribe to the Roller user/dev list and discuss them with the Roller team. If you encounter bugs, please report them to Roller's JIRA issue tracker.

Here is the README that is included in the build:

ROLLER 2.0 EA DEMO RELEASE

This is a totally unofficial demo and test release of the Roller blog server 
software. Roller is currently in the incubator at Apache, but this release is
