configure apache Tomcat 5.x for Turkey?
(2) at present, i want to find out about an error message ---
java.lang.NumberFormatException: For input string: "0,00"

Read the java api docs for java.lang.NumberFormatException and
java.lang.Float. Specifically the following link should shed some light
on the exception:
http://java.sun.com/j2se/1.5.0/docs/api/java/lang/Float.html#valueOf(java.lang.String)
There's also a link there to java.text.NumberFormat which should provide
some methods for localized parsing of values.

Tomcat should default to the locale of the JVM, so you should switch the
locale of your JVM in order to get Tomcat into Turkey's locale.

Run the following program and check the values for "user.language" and
"user.country". If they don't match what you expect, then your JVM is
not yet configured properly.
public class Env
{
public static void main(String[] args)
{
System.getProperties().list(System.out);
}
}
Now, on to the /real/ problem. What you have done is use
Float.parseFloat() in order to read-in a floating-point number. This is
never ever going to work for you, assuming that Turkey doesn't follow
the English convention of using a dot ('.') as the decimal separator.
The problem is that Float.parseFloat is written to read only
English-formatted floating point numbers. It will always fail to read
"0,00" as a floating-point value, regardless of your JVM (or Tomcat)
settings. It will always fail.
Instead of Float.parseFloat, you need to use the localizable tools found
in the java.text package. The most important one for you is the
DecimalFormat class (although I'll be using the NumberFormat class
instead for convenience). Here's a quick idea for how to use it.
You used to have this:
float f = Float.parseFloat("0,00");
You need to change it to this:
import java.text.NumberFormat;
.
.
NumberFormat nf = NumberFormat.getNumberInstance(yourLocale);
float f = nf.parse("0,00").floatValue();
This ought to work for you. Note that 0,00 isn't the best test value ;)
This article might help you once you get more into using the
NumberFormat class:

Good luck,

what I am saying is that I don't believe java.lang.Float.parseFloat
parses according to the local, it always uses "." and not ","
so changing your locale will most likely not affect the Float.parseFloat
operation.
hence you should use the java.text.DecimalFormat

filip, thanks. but turkey locale uses "," to denote decimal vs "." in USA.
for further testing, plz tell me what changes i need to make to tomcat to
use turkey locale so that i can test my app in usa?

it's your "," character.
you need to use the java.text.DecimalFormat class
