Ya, the JNI can be nasty.... About a year ago I tried to connect to a VB6
generated DLL with little to no success.... I eventually sought the words of a
wise sage.... Mark Long.

Jim,
The 1.5 and later versions of java have a facility like the C/C++ sprintf()
function. You can allocate a buffer and just have it write them in there. I
think with a format specifier like "%05d".
Your task is much easier than mine. LOL
You have to love that JNI stuff, right?
Best,
J. R.

G'day Jim,
If I understand your question you want the two byte representation of the
integer value when the properties get method is called? I'd suggest checking
out the java.text classes and perhaps using, if I recall right,
SimpleTextFormat. I've done something similar in the past to display a numeric
value as a literal which was padded out with leading 0's.
Cheers.

Sorry for the cross posting.... I have a COBOL copybook that defines an element
as Pic 9(5)...
In my Java class I need to pass into my setter an integer for obvious reasons.
COBOL under the hood needs me to pass 00000 if the field is empty because I'm
actually building the com area at this point. If however the field contains 999
I must still pass 00999 to fulfil the expected length....
Ok, I have a string "00999" and need to convert it to an integer.... If I do
so, then the leading zeros are stripped off and my com area is 2 bytes
short.... Don't ask why or how it's the way it is....
So, how do I manage this?
