    java


    Do you need the jre in both 32-bit and 64-bit installed on your system or can you go wholey 64-bit for use with whichever browser you use (including 64-bit ones)?

    Only if you use a x32 browser do you need both. Otherwise, use the x64 one.

    Exactly. We're all in the same boat.

    That's what I do too; for frustration's sake.

    I do both too - but I have noticed more than once that if I code an app using an IDE that is pointing to the 64bit version of JAVA and then take it to a machine with the same IDE but pointing to a 32bit version, it has gone screwy on me a couple of times - I cannot understand how as I thought the APIs were identical.....

    But I still keep both.

    Wouldn't the API's source for x86 and x64 be different?

    I wouldn't think so, other than location, if my supposition that the APIs themselves are the same....

    But I may be wrong....

    yep im the same boat as you are....:)
    the only thing i can think of is that something is different when compiling to byte code changes enough to affect whether it was compiled in 32 or 64...
    had to compile 32 bit as the class computers are using 32bit xp...[shudder]...
