1. Make it executable: "chmod 755 j2sdk-1_3_1_12-linux-i586.bin"
2. Run it: "./j2sdk-1_3_1_12-linux-i586.bin"

Newbie-friendly alternative to that same code would be

chmod u+x filename

, which adds ("+") execute ("x") privileges to the user ("u").

Obviously dolda2000's answer is cleaner/more precise, but sometimes it's helpful to be able to visualize some of these commands.

Of course the man pages would explain how both ways of specifying the mode can be used.
