How to install java in slackware the right way?

What I'm trying to get to work now is snipsnap.

It says it needs java SDK 1.4 or better. I went for jdk-6u1 which should fit (right?). Downloaded the self extracting binary from -> JDK 6u1 download -> Linux self-extracting file and saved it to /usr/src/tar.
I didn't really have any idea what I was doing so I ran it with
and installed it. It made a folder right there called jdk1.6.0_01. Moved it to /usr/src but then I realized It wasn't the source code but it had already compiled. Okay I figured it was working and ran snipsnap's
root@SERVER:/usr/src/snipsnap-1.0b3-uttoxeter# ./
Error occurred during initialization of VM
Could not reserve enough space for object heap
I went to snipsnap's lib directory and run some file with
java -jar snipsnap.jar
which said JAVA_HOME wasn't right. Alright, long story short, I finally copied jdk1.6.0_01's files to /usr/lib/jre1.5.0_09/ which I figured was the same version but really wasn't and did
export JAVA_HOME="/usr/lib/jre1.5.0_09/"
Some things of snipsnap still don't seem to work and I think I have to install java correctly first so I can run it from

All this wasn't really even important : D, I just wanted to know, what the right steps should be when installing jdk1.6.0_01 from binary.

Have a look on your local Slackware mirror. jdk-6u1 has been added to Slackware-current. Perhaps if you look in the /slackware-current/extra/source/jdk-6 directory, you'll be able to look at Pat's Slackbuild file and see how he does it.

Funnily enough on WinXP yesterday (!) I came across this heap memory thing.

The help (for jEdit) said to run with the flag "-Xms64m" (IIRC); or higher number like 128 (or higher numbers in integrals of 16). So, eg
java -Xms64m -jar ./somejavathing.jar
See for more about heap errors for various apps.

Hey thanks, It kind of works. I know that noone probably uses snipsnap here but it's homepage seems to be pretty dead so I'll post my last problem here just in case. When I make a snipsnap server it appears on my local network as the ip of the server running it (, I anyone knows how I can make it into a internet public ip so others can actually see it, I'd be tremendously thankful. Thanks again for both of your's help.

Edit: I think I may have figured it out. I just have to use my router as a virtual server.
