hello,

If you used jdk 1.5+, you will can try the String method replace (link
below), this way, all comma separator in the number will be change in dot
separators. Take care with numbers that contains dot separtor as decimal
before execute this one.

Hi,

Thanks for advice. 
Finally I sued 


double val = Double.parseDouble(strValue.replace(oldChar, newChar));
In my case it was:



 
double resultDoub = Double.parseDouble(resultStr.replace(",", "."
));

Rafal

Take a look at NumberFormat:

http://download.oracle.com/javase/1,5.0/docs/api/java/text/NumberFormat.html



public abstract class NumberFormat
extends Format

NumberFormat is the abstract base class for all number formats. This class provides the interface for formatting and parsing numbers. NumberFormat also provides methods for determining which locales have number formats, and what their names are.
NumberFormat helps you to format and parse numbers for any locale. Your code can be completely independent of the locale conventions for decimal points, thousands-separators, or even the particular decimal digits used, or whether the number format is even decimal.
To format a number for the current Locale, use one of the factory class methods:

  myString = NumberFormat.getInstance().format(myNumber);
 

If you are formatting multiple numbers, it is more efficient to get the format and use it multiple times so that the system doesn't have to fetch the information about the local language and country conventions multiple times.

 NumberFormat nf = NumberFormat.getInstance();
 for (int i = 0; i < a.length; ++i) {
 output.println(nf.format(myNumber[i]) + "; ");
 }
 

To format a number for a different Locale, specify it in the call to getInstance.

 NumberFormat nf = NumberFormat.getInstance(Locale.FRENCH);
 

You can also use a NumberFormat to parse numbers:

 myNumber = nf.parse(myString);

Take a look at NumberFormat:

http://download.oracle.com/javase/1,5.0/docs/api/java/text/NumberFormat.html


public abstract class *NumberFormat*extends Format


NumberFormat is the abstract base class for all number formats. This class
provides the interface for formatting and parsing numbers. NumberFormat also
provides methods for determining which locales have number formats, and what
their names are.

NumberFormat helps you to format and parse numbers for any locale. Your code
can be completely independent of the locale conventions for decimal points,
thousands-separators, or even the particular decimal digits used, or whether
the number format is even decimal.

To format a number for the current Locale, use one of the factory class
methods:

  myString = NumberFormat.getInstance().format(myNumber);


If you are formatting multiple numbers, it is more efficient to get the
format and use it multiple times so that the system doesn't have to fetch
the information about the local language and country conventions multiple
times.

 NumberFormat nf = NumberFormat.getInstance();
 for (int i = 0; i < a.length; ++i) {
 output.println(nf.format(myNumber[i]) + "; ");
 }


To format a number for a different Locale, specify it in the call to
getInstance.

 NumberFormat nf = NumberFormat.getInstance(Locale.FRENCH);


You can also use a NumberFormat to parse numbers:

 myNumber = nf.parse(myString);
