yum search JVM?
Some stuff found, but no JVMs….
Hmm, okay….I looking at what it takes to get a JVM loaded on my fedora core laptop…I’m looking to write some routines that allow java programs to authenticate off of a gforge user database. I’ve written these same routines in python already, so a part of me wants to try the jython route, as it might be fast and fun to do so, but either way I’ll need a JVM on this laptop, so I download the SDK from sun.
Additionally, I want to hack up some j2me stuff for the game, sooner or later, to run on phones like my Treo and other phones (and yes, my head is in the sand regarding midp quality and such, but allow me my illusions, okay?), but for now I’m sticking with regular old j2se for the gforge project.
Gforge project leader Tim Perdue keeps threatening to switch from php to Java for gforge 4.0. Although most people don’t think it will happen that way, it is worth my time to look into it. Tony Guntharp and I service Real Network’s helixcommunity.org site, HC.org runs Gforge, means we care about the future directions of the codebase. Gforge is currently written in PHP and since mailman is so fundamental to its mail operation, some python.
Which brings up an interesting point, python is scary fast….and while I’m not looking to revive the java is slow debate, python, speed wise, is to php what php is to mod_perl and that is saying something. All three are pretty terrific scripting languages, so don’t read too much into that, but the speed differences are really something. Mind you this is based on php 4.x numbers and not 5.x which I haven’t installed yet.
Of course this brings up Java Server Pages and such, but for now, I just want to write some routines to query against gforge. The download, which is some 33 megabytes or so, is almost complete, Now Installing (timing it for our information)…
It would be really worthwhile for sun to provide packages in a yum or apt repository, but its probably pretty obvious that I feel that way, it’s how we do things, I wonder why they don’t do that, or for that matter where is IBM and the other JVM shops? It’s so much easer to keep up with security patching on the rest via these kinds of systems, anyhow…
I’m probably missing something, likely someone has a yum repository up for java, but as I mentioned in an earlier post, I’m a java neophyte by any real measure, and I’m writing on LJN because of my Linux background, so much of this will be very beginner to some readers..
Oh, and while it is downloading, one more thing…. For shame, JBoss, that’s really lame, I didn’t mention this before, but for shame. When I worked at Slashdot, we’d see these kinds of campaigns all the time, and that’s why moderation was developed. But super lame. Ah, looks like the download is done (yay DSL!)!
Do I agree? Again? Didn’t I agree when I downloaded? “yes” … Extracting rpm… rpm -Uvh etc…. done…
K, lets test the install a little bit…helloworld works… excellent…total time to install to this point: 15 minutes or so, not so bad, of that most was hacking about on suns site and such, I think the actual install time post download could have been around 3 minutes if it were properly integrated into yum/apt/etc…
It is fair to compare these against PHP and python, which can be loaded very easily via the various package mangers like yum and apt, including extra features like MySQL (yum install php-MySQL) and imap (install php-imap). Java would benefit from this kind of installation procedure:
yum install j2se
yum install j2me
You get the point, yum and those tools will even add paths properly for you and the rest that you must do by hand with sun’s downloads, but all in all it went smoothly enough, no segfaults on my strangely updated fedora core laptop, so I’m happy. When deploying linux machines into data centers, I can say with confidence that I’d rather use a decent, updating package management system like yum than have to download things like java seperately from those processes.
yum install java? Not so fast…
