[ptp-dev] 32- or 64-bit Eclipse?

[Jeffrey Overbey <jeffreyoverbey@xxxxxxx>]

One question we've gotten at our tutorials is, "Should I download the 
32- or 64-bit version of Eclipse?"  I'd like to post an answer in our 
FAQ, so... is this right?  The Java command seems to work with both 
HotSpot and J9.


Q: Should I download the 32- or 64-bit version of Eclipse?

A: It depends on whether your Java Virtual Machine (JVM) is 32- or 
64-bit.  To determine this, open a terminal/command prompt and type:
    java -d64 -version

If an error message is displayed ("Running a 64-bit JVM is not supported 
on this platform."), then you have a 32-bit JVM, and you should download 
the 32-bit version

If there is no error message -- the command displays version information 
for your JVM -- then your JVM is 64-bit, and you should download the 
64-bit version of Eclipse.
