One more basic question with Compound message

Question

Hello,
i wanted to know one thing :
Using JOptionPane , or on a JLabel , sometime i need to display some message which value is a variable (i mean whole message is variable) ,
for ex.
JOptionPane.showMessageDialog(null, result, "Error", JOptionPane.OK_CANCEL_OPTION);
or
JLabel label = new JLabel();
label.setText(result);
NOW in both cases "result" is variable ( a String )
HOW to localize it ?
As i understand it wont be possible to localize it.
Please suggest .
thanx for ur time and help,
Rajesh

All you have to do is store all possible error messages in your ResourceBundle files. The following is a section of my ResourceBundle.properties file:
# ParseException messages
err0 =Unexpected end of expression
err1 =Parenthesis or Bracket mismatched
err2 =Too many arguments
err3 =Too few arguments
err4 =Variable or Constant expected after an operator
err5 =Missing right brace
err6 =Unexpected comma
err7 =Invalid range name or address
err8 =Unrecognized function name
err9 =Invalid numeric constant
err10=Unrecognized operator
err11=Unterminated string
err12=Operator expected
err13=Unrecognized array delimiter
err14=Unrecognized array constant
err15=Not a balanced array
err16=Invalid If-Then-Else format
err17=Invalid Expression
err18=Named variable not accompanied by an assignment operator
Now, in a ResourceBundle for a specific Locale, the characters to the right of the equal sign (=) would be translated into the correct characters for the Locale.
The way it works in my program is that given the error number encountered, I would fetch the appropriate error message and store it in something similar to your result and display it (so it effect, result is a variable). For example:
             ResourceBundle F=PropertyResourceBundle.getBundle("myErrMsg",Locale.getDefault());
             if (j<0) {
                 errmsg=F.getLocalizedMessage("err18");
                 throw new ParseException("",errmsg,0);That's how you have to do it......
I guess what I'm trying to say is you can make result a variable to a certain extent but since you need to internationalize it, the only way to do it, as far as I know, is by using the ResourceBundle.
