Characters conversion

Question

Hello,
I'm working on a conversion problem between windows and unicode representations of characters.
I would like to get, for instance for the euro character, the windows encoding value (128) from its unicode encoding value (8364), and vice versa.
�        8364          128   (unicode / windows)
�        8218          130
�        402          131
�        8222          132
�        8230          133
�        8224          134
...I've found on the internet a way to get 128 from 8364 :
String s = "�";
byte b[] = s.getBytes();
int code = (int) (b[0] & 0xff);
By the way, if someone could explain me how it works... ;)
I'm looking now for a way to do the opposite, get 8364 from 128...
Thank you a lot in advance.
Bye!

Thank you for your answers.
hunter90000, you're right, the "windows" charset is windows-1252. But what I'm looking for is a way to get 8364 from 128. If someone could help me unterstand the code below, I think I could find it :
String s = "�";
System.out.println( (int) s.charAt(0));                 --> 128
byte b[] = s.getBytes();
int code = (int) (b[0] & 0xff);
System.out.println(code);                                -->8364
System.out.println((char) code);                        -->�The reason why I want to get 8364:
I'm manipulating a xml file to send data to a web browser via an ajax function. This data provide from an Oracle database, in which the euro character has the value 128.
The only way I've found to display correctly the euro character on the browser is to encode it & # 8364; in the xml file, even if the charset of this one and of the JSP is 'ISO-8859-15'...
The problem is not limited to the euro character, but to all the carachters in the following list :
   (8364 . 128)
    (8218 . 130)
    (402 . 131)
    (8222 . 132)
    (8230 . 133)
    (8224 . 134)
    (8225 . 135)
    (710 . 136)
    (8240 . 137)
    (352 . 138)
    (8249 . 139)
    (338 . 140)
    (381 . 142)
    (8216 . 145)
    (8217 . 146)
    (8220 . 147)
    (8221 . 148)
    (8226 . 149)
    (8211 . 150)
    (8212 . 151)
    (732 . 152)
    (8482 . 153)
    (353 . 154)
    (8250 . 155)
    (339 . 156)
    (382 . 158)
    (376 . 159)
