Using Ivy in AppFuse I'll admit, the thought of not checking in JARs to AppFuse's CVS is intriguing. With Ivy, I think I could pull off the current setup, plus a dynamic-downloading system. By current setup, I mean that the JARs are distributed in your "lib" directory and you can build your app w/o downloading any dependencies. I like this because I can develop AppFuse and not worry about my internet connection.

Dion doesn't get my love for checking in JARs. The main reason I do it is because it takes me a less time to download a new release and check it into CVS than it takes me to find that same release in Maven's Repo. Case in point: Hibernate 3.

I love the idea of Ivy, and mockhaug makes it sounds great, but I don't want to have to create a bunch of metadata whenever I want to use something like Hibernate 3. Then again, if Ivy is ever going to catch on, someone has to do it.

In conclusion, I'm still not convinced I should integrate Ivy into AppFuse - sounds like maintaining and uploading dependencies would be a lot more work than just checking in JARs. If there was a person responsible for creating Ivy metadata every time a new release came out, I might think different. Posted in Java at Apr 13 2005, 02:19:21 PM MDT 6 Comments

Very cool search with XMLHttpRequest From fiftyfoureleven.com, I learned about forgetfoo.com - which is doing some very cool stuff with XMLHttpRequest. Be sure to check out the calendar, comments and naked picture of Britney Spears.

While we're on the topic of cool stuff, I also learned about this cross-browser Nifty Corners component. Should we call a set of CSS+JavaScript files a component I think so, what else would you call it? Posted in Java at Apr 13 2005, 11:13:55 AM MDT 4 Comments

Closures with CollectionUtils Here's a pretty nifty trick for using closure's with Jakarta Commons CollectionUtils:

List list = new ArrayList();
...
CollectionUtils.forAllDo(list, new Closure() {
    public void execute(Object obj) {
    // execute something for each item obj
    }
});

I wonder if there's any performance hit from doing things this way vs. a good ol' Iterator? Hat tip to Anand Subramanian.
