RE: Java help - convert -D command line option to CF?
Perhaps, you can try to instantiate java.lang.System and set the system property in the coldfusion code? Something like, cfset sys = createObject(java, java.lang.System) cfset sys.setProperty(com.java4less.vision.maxarea, 9) Hope that helps.

The component in question is probably this: http://www.java4less.com/vision/vision.php Presumably, your class is either using this, or using something which is using this? Anyway, it seems to me that you have three options. Add the option to jvm.config, invoke your program from CFEXECUTE instead of integrating it into your CF code, or modify the source code of the component to contain this value as a default.

RE: Java help
Thanks for the suggestion. I saw that link before but dismissed it for some
reason. I guess I assumed it was doing something else. In any event, I just
tried it and it DID come up with different output but still not what it
should be. I may very well be using it wrong though. It's probably obvious
that I'm no Java programmer. I'm basically just taking what I know about
programming in general and the syntax of JavaScript and doing the best I can
here.
This is what I have from your suggestion and what it displays.
import java.text.*;
import java.math.BigDecimal;
public class dollarFormattingTest
{
public static void main(String[] args)
{
DecimalFormat dollarFormat = new DecimalFormat($0.00);
System.out.println(dollarFormat.format(new java.math.BigDecimal(71.815)));
System.out.println(dollarFormat.format(new java.math.BigDecimal(71.825)));
System.out.println(dollarFormat.format(new java.math.BigDecimal(71.835)));
System.out.println(dollarFormat.format(new java.math.BigDecimal(71.845)));
System.out.println(dollarFormat.format(new java.math.BigDecimal(71.855)));
System.out.println(dollarFormat.format(new java.math.BigDecimal(71.865)));

System.out.println(dollarFormat.format(new java.math.BigDecimal(71.885)));
System.out.println(dollarFormat.format(new java.math.BigDecimal(71.895)));
}
}
This is the output now...

$71.83
$71.83
$71.84
$71.86
$71.86
$71.88
$71.89
$71.89
That's either extremely weird... or I'm completely missing something
obvious. :-/

Re: Java help
Bobby,
I think this is what you want:
import java.math.*;
import java.text.*;
import java.util.Locale;
public class BigDecimalFormatTest {
public static void main (String[] args) {
double [] nums = {71.715,71.725,71.735,71.745,71.755,71.765,71.775,71.785,
71.795};
NumberFormat form;
form = NumberFormat.getCurrencyInstance(Locale.US);
for (int i = 0; i nums.length; ++i) {
BigDecimal theNumber = new BigDecimal (Double.toString(nums[i]));
theNumber = theNumber.setScale(2, RoundingMode.HALF_UP);
System.out.println(form.format(theNumber));
}
}
}
The key here is the double conversion to BigDecimal and setting the rounding
mode to half_up. The reason you weren't getting what you thought you should
is because DecimalFormat uses the half_even rounding mode.

It gives the same exact results. Everything is fine as long as it's not a 5
in the 1000ths position.

Subject: OT: Java help
Can anyone lend a hand with this off-list by chance? I need a dollarformat
function in Java. I thought I had it but it doesnt round correctly. Take
this short example.
import java.text.*;
import java.util.Locale;
public class dollarFormattingTest
{
public static void main(String[] args)
{
NumberFormat dollarFormat =
NumberFormat.getCurrencyInstance(Locale.US);
System.out.println(dollarFormat.format(71.715));
System.out.println(dollarFormat.format(71.725));
System.out.println(dollarFormat.format(71.735));
System.out.println(dollarFormat.format(71.745));
System.out.println(dollarFormat.format(71.755));
System.out.println(dollarFormat.format(71.765));
System.out.println(dollarFormat.format(71.775));
System.out.println(dollarFormat.format(71.785));
System.out.println(dollarFormat.format(71.795));
}
}
That short program outputs the following
$71.72
$71.72
$71.74
$71.74
$71.76
$71.76
$71.78
$71.78
$71.80
If I change all the numbers to put a 6 in the 1000ths position, compile, and
run again they all round up fine just as they should. And anything under a 5
in that position seems fine as well (the 1000ths position is simply
dropped).
Any ideas?
