x86 refers to 32-bit software. x86_64 and x64 both refer to 64-bit software. Running 32-bit software on a 64-bit version of Linux is not the same as on Windows where 32-bit apps are thrown into a Program Files (x86) folder, some modifications are needed such as installing ia32 libraries.

You'll still need ia32, here's an article tailored to fedora (scroll down to Installing 32-bit support libraries under 64-bit Fedora 9 Sulphur ):… . It's for Fedora 9 but it's still relevant with the ia32 libs. – John T Jan 17 '10 at 11:09
will the 32 bit linux version work on x64 – Rohit Banga Jan 17 '10 at 11:13
I have no idea as I haven't tried it. Some applications do not work with ia32. Out of curiosity, why aren't you using the 64-bit build of java? – John T Jan 17 '10 at 11:15
