Free and Excellent Code Coverage for Eclipse

The EMMA plugin for Eclipse is my latest addition to the "can't live without it" category. It allows you to run applications and test suites from within Eclipse and gather code coverage ... better yet, that code coverage data is shown visibly in your code, much as it is in an HTML Cobertura report.

The plugin is slick, fast, easy and non-intrusive.

The one thing you do need to do is split your output directories, so that production code goes into bin, and test code goes into test-bin; this allows you to turn off coverage information for your test classes, and just gather

Of course, IDEA also has code coverage, based on EMMA, built right in.

Tapestry at JavaOne 2007

JavaOne was a lot of fun this year; I didn't arrive in time for the JavaFX keynote, but I understood it to be underwhelming. Yep ... that's what Java needs ... to take on Adobe and Microsoft in Adobe's home territory.

On the other hand, this was a very social JavaOne; lots of good conversations and meeting with people I only know online.

I also attended the Java Server Faces 2.0 Expert Group kickoff. I can't really see where that's going to go, alas. It's not like everyone bowed down and said "JSF 2.0 shall be Tapestry" (not even Jacob Hookom, who does see Tapestry as a good model for much of JSF 2.0). But I did get a chance to chat with Gavin King ... about motorcycles. He's riding a Ducati now, and I'm thinking about picking up a new bike once I buy a house. Gavin --- I used to ride a Yamaha FZR1000.

The best part of the JSF meeting was when Jonathan Swartz stopped by. We shook hands and talked about how slow adoption of JCP standards.

Elsewhere ... the fun part about the RubyEnv parody ad ...

... is that Tapestry is jar #3. Interesting, though I guess it's hard to know what "JSF in a Jar" looks like, or "Struts in a Jar" for that matter. My intention is to reverse the meaning, make Tapestry 5 something that'll make the Ruby guys envious. We'll see.

Tapestry at JavaOne

Not only am I doing my Tapestry 5 "BOF" session (Tapestry 5: Java Programming Language Power, Scripting Ease), but there's also TS-7354 (Fast Feedback Loop: Unit Testing Strategies for Tapestry) and BOF-9834 ( Grails, Sails, and Trails: Rails Through a Coffee Filter).

I'll be arriving Tuesday afternoon and staying through Saturday. JavaOne is always hectic, especially right around my session. However, I'd be glad to meet with people informally; drop me an e-mail at hlship AT gmail DOT com and we'll see.

Meanwhile, did anyone else suffer through Sun's Schedule Builder? Just a horrendous application, made all the worse that it is crying out for the Ajax treatment. Show me the sessions side-by-side, dynamically filter the page by day and time slot and session track, and let me click or drag the sessions I like. For god's sake ... don't make me schedule one sesson at a time and then scroll back to the top of the page!

Launching IntelliJ for the first time...

First the damn cool crowd of NFJS speakers got me to buy a Mac, now they've suckered me into switching from Eclipse to IntelliJ. God help me, I don't even know where to start with this thing.
