32-bit or 64-bit JRE?

Hi!

I have trouble knowing of what javaversion i should choose! maybe both?

I dont realy understand how it works. Are they the same thing, just that the 64-bit JRE runs faster?

Must the application be written in 64-bit for it to be able to use the 64-bit JRE?

How does it work? Should i install both?

It's as per your operating system.

I chose 32 over 64 though I have a 64 Bit system. The reason was a compatibility issue with third party drivers... if you don't have that you should go for 64 Bit I guess.

This is what i am afraid of, but i guess i will have to test the 64-bit before deployment. :=-:

Well from my experience it should be only for driver interaction that you really get into problems. Least java applications actually have direct driver interaction in my opinion. For me it was the "libusb" project that was giving me trouble in conjunction with missing hardware manufacturer driver support. So... well it might have been very specific.
