/usr/bin/make-jpkg-mustang

I’m in mid process of creating a “.deb” file containing Java 6. Why am I’m blogging about it? Well because it’s been next to impossible to do. I started trying to install Mustang about a month or two ago and I cuoldn’t get it. I posted on Kubuntu forums and got nowhere. The problem is that Java has always been a pain to install on Linux. Why somebody doesn’t rectify that longstanding issues puzzles me to this very day. To start you have to figure out which version of the JDK/JRE you want. (Windows, Linux, Solaris, SPARC, what the hell is a SPARC anyway?) That’s not too bad then you download the package. Debian/Ubuntu purists like myself hate the thought of installing software without a .deb file yet Sun offers no .deb distribution for Java. (They’re very friendly towards Windows and RedHat based distros.) So now you have this dumb self extracting file sitting on your hard drive that your afraid to touch until you can find the magic wand that turns it into that precious .deb you’ve been dreaming about. If you’ve read my blog before you may have seen an old article explaining the proper way to install Java on Debian/Ubuntu systems. That only half applies to the latest release of Java. According to my research (and prior efforts) the make-jpkg scripts will not work with Mustang leaving Debian-based distro users to further stare holes into the section of the screen higlighting a useless bin file. If your smart enough you’ll type make-jpkg mustang into Google and feel rejoiced at the link near the top of the page. (Currently I’m getting connection refused on the link but Google’s cached copy didn’t let me down!) Before you break out the fine wine let me pop your balloon and tell you that the new make-jpkg-mustang script doesn’t work. That’s where I started from this afternoon. Since nobody has been able to help me with an alternate reccomendation I’ve taken matters into my own hands. I rolled up my sleeves, dug into the broken script and patched it as best as I can. After a few iterations of “read script, run, cuss, edit, repeat” I was finally able to generate the “.deb” file I so longed to have stuffed into my distro. I installed my beauty and ran “sudo update alternatives –config java” to adjust my system to the latest and greatest from Sun only to find out in horror that I had in fact installed a JRE not a JDK. As a Java developer a JRE is next to useless to me so again I glared holes into the center of my Konqueror window frame. I was confused! I confirmed that I did in fact download a JDK yet what I had created and installed with the make-jpkg-mustang script was only a JRE!

I’m no Debian developer…
But I have read up on the .deb file format in the past, so I know a little about how it works. After reading the script, shedding a few more random swear words and a few more iterations of the earlier cycle I mustered a deb archive that included the entire JDK. I was happy as … until I re-ran update alternatives. Where the heck was my new JDK? Four more iterations of the cycle that would make Eddie Murphy cover his ears and I think I finally have something. I’m no Debian guru like I said before so my revisions to the script may be flawed or horribly incorrect but now Mustang shows up in update-alternatives as well as in Synaptic. Also, all of the JDK is in there instead of just the JVM. I’m placing my revisions below so you all can cheer, laugh, poke fun at, or rip apart. Hit me up, people…
