RE: While I'm choosing Hibernate over JDO ... for now

Now I will talk to you about the dealbreaker - the one thing about JDO that pushed me pretty rapidly over to the Hibernate camp: the query language. The JDO query language is just poor, very poor and of a syntax that only the designer could appreciate.

Class gameObjectClass = com.foo.GameObject.class;
Extent oldObjects = pm.getExtent (gameObjectClass, false);
String filter = "age > 25";
Query q = pm.newQuery (gameObjectClass, oldObjects, filter);
Collection oldGameObjects = q.execute ();

This unfortunately gets more and more complex as you have to introduce other variables into the query. This is a major failing of JDO IMO. Hibernate was just so much easier to deal with from the query perspective (and since that's what you'll be spending most of your time doing...).

List oldObjects = sess.find( "from obj in class com.foo.GameObjects where age > 25" );

Big difference in both presentation, LOC and generally understandability in my opinion. [Nation of Greg :: Redux]

I have to agree with Greg here. Hibernate's query language (HQL) is extremely easy to use. In fact, I've been amazed at how I've been able to guess the syntax and get it right 9 times out of 10! It's the best of SQL and OQL. If you think HQL is good - wait until you checkout the Query by Criteria syntax (very cool IMO). There's supposed to be a Hibernate 2.0 Final this weekend... only 26 hours left in my neck of the woods.

Infecting Myself with BugBear

I've gotten two e-mails with the BugBear virus this morning - both from my alter ego. Actually they were from "[email protected]", which doesn't exist. Strangely, it's a response to an e-mail I sent to the struts-user mailing list. I've received them so far on Yahoo and my Comcast e-mail, both of which have webmail interfaces, and therefore, no problems have ensued. In case you get an e-mail from me (or rather [email protected]) with the subject Re: Is it possible to change the base tile on the fly, kindly delete it.

I'm slapping this sucker in my Java category in order to reach a greater audience. Hope you don't mind.

w.bloggar problems with Roller

I've been trying to post to this site with w.bloggar with morning. It's been working, however, w.bloggar doesn't think it is. When I click "Post", it gives me a w.bloggar: 500 dialog that states: HTTP POST failed. The error number is returned HTTP status code. I upgraded this site to use the latest snapshot of Roller from CVS, but no luck, I still get the same error. I don't normally use w.bloggar, so it's not a big deal. However, moblogger is also failing.

As for the Roller upgrade, the only noticeable changes are 1) the "Editor" menu has changed from showing tabs/sublinks to just sublinks on my Weblog page, and 2) it seems to ping weblogs.com after I update. There are some issues behind the scenes, but they don't seem to be affecting anything too badly. I guess I'd better turn off e-mail notification of errors - I've received 80 since I upgraded!

Out-of-the-Box - My Review

It figures, after bitching about the lack of ROI for Developers on Open Source projects, I get an e-mail from Rob Cope of Out-of-the-Box. The e-mail said that I could get a free version of Out-of-the-Box Enterprise Edition for my contribution to the open source community.

So I think, "wicked cool" - this software sounds great! I downloaded (500 MB) and installed it, and that was the end of my experience with OOTB. No instructions on what to do next. I perused around the filesystem it installed and tried to run ant in a few directories, but no luck. So OOTB just gives me a bunch of OSS projects on my hard-drive, but they aren't built. I don't want to know what I'm doing wrong - I want to know where the documentation is that tells me what to do. I'd dig it if it let me install them projects (i.e. Apache) where I wanted, and also allowed me to upgrade existing installations. If it could migrate my existing settings or customizations, that would be even better. That is what I want.

That being said, I don't think I have much use for OOTB. Why? Because it's not updated enough. I'm the type of upgrade-happy SOB that wants to download and use as soon as the release announcement goes out. I want to get the latest snapshot from CVS and see if it solves my problems. I want to patch my local copy and fix the bugs myself. I want to install some applications in $TOOLS_HOME, and some in $SDKS_HOME. Lastly, while it's nice that OOTB sets the environment variables for me ($JAVA_HOME and $ANT_HOME), I'd appreciate it if it didn't overwrite my existing ones. A simple prompt to see if I want to change them would be sufficient. Especially since I have a newer version of Ant (1.5.3-1 vs. 1.5.3) than OOTB. I don't mean to be too critical - I just want to voice my true feelings. ;-)

JavaOne - Developer Coverage from Sue Spielman

Sue Spielman, local Java/Struts Guru, is heading out to JavaOne next week and promises developer coverage (minus the marketing hype) in a DJUG e-mail today. [More] Who's going to start compiling the list of JavaOne bloggers?

RE: Eclipse 3.0 M1 is out!

Here is a link to all the cool new features in this release! You can download from here. [A Cup of Joe]

The upgrade-happy developer in me can't help but click the download link. The New and Noteworthy page (near the bottom) notes many improvements to Eclipse on the Mac. I'd really love it if Eclipse was fast on OS X and Apple released OS X on Intel. I really dig the OS, just not the speed of the hardware.
