tlug: Java and Japanese

[Craig Oda <craig@example.com>]

tlug note from Craig Oda <craig@example.com>
--------------------------------------------------------
Hi,
thanks to Tsurui-san from Toshiba CAE Systems, I tested out 
getBytes("8859_1") and now have a working servlet that mails
me the contents of a Japanese HTML form and writes to a file
in JIS, ShiftJIS, and EUC.  The code is purely for testing.  I'm
posting it because I'm excited about the getBytes("EUC"),
getBytes("SJIS"), and getBytes("JIS"), think it's mondo cool.

I also have about 25 pages of Japanese mailing list archives dealing
with Java, Japanese and SQL databases that I may edit and
put on my home page one day.  Evidently, the database JDBC 
driver people had the same problem with Strings that I had
with the servlet.  Fascinating stuff.  

I'm about to watch my Japanese drama, so I'll post my test
here for the benefit of others.  I'll probably have a couple
of clean objects in a couple of days that can be used to
handle generic Japanese forms, so let me know if anyone
wants it.  Though, the weekend is coming up and I've been 
wanting to go outside.   

I'm not sure what the "8859_1" means.  Does anyone know?


Regards,
Craig

    conversion classes.  It also uses Sun's servlet development kit 1.0.
    I've tested input into the form with EUC encoding under Linux and
    ShiftJIS under Apple Macintosh Kanji Talk.  

This is the HTML test form.
