Nimbostratus
NimbostratusGot a negative integer which returned by getLow();
As the structure defined as below . high/low are unsigned integer .
struct Common.ULong64 {
long high;
long low;
};
However, I got a negative integer ..

Joe's code will work fine.... Java now implements longs as 64 bit numbers, and supports unsigned longs, so all should be great if you use his code. My only suggestion would be to declare myresult in his sample as unsigned long instead of long, so you don't get rollover on very large numbers.
Oh, and the UsefulU64 class in the wrappers will just handle all of this for you, if you have the wrappers downloaded. Unfortunately, we can't offer the source at this time, but it will do the conversions for you.
Don.
