Subject Re: [axis] LF vs CR/LF in axis generated code
Date Wed, 05 Jun 2002 14:49:44 GMT
We've got to be clear here.  We're talking about 2 different things.
1.  wire message values
2.  generated code

My statement applies to generated code.

The spec tells you to make sure that your implementation send out the
wire  values (in bytes) of

 GET / HTTP/1.0<cr><lf>

i.e. in Hex

 { x47,x45,x54,x20,x2f,x20,x48,x54,x54,
  x50,x2f,x31,x2e,x30,x0d,x0a };

so if you are sure that your

 String j = "GET / HTTP/1.0\r\n"

when written out on the network yields those bytes being send out in
exactly that order; *regardless* of the LOCALE the user may have set or
other properties of the compilers(*), JVM, etc - then you are fine.

Which you are in most java(*) environments.

Otherwise you'll need to do something more fundamental when you convert
down to wire format.


* This is not as trivial if it sounds; some charset's will
  substitute the lowercase 'l' for a '1' when mapping from
  that to the iso or ascii charset. Likewise some charset
  simply lack certain characters; say the H or the K as they
  are not used in languages - and you may get country or
  language specific substitutions such as to a 'G' or a
  'Kappa' symbol.

  One particular fun area is for example when quering (oracle) databases
  from a locale different than the locale programmed/entered in. And even
  though all is UTF-8/unicode; a 'e'-trema may be receid back as a syngle
  code point -or- as a 'e'-'backspace'-'trema'. Or a cyrillic 'c'
  may end up being another code point; etc. I.e. they all look as glyphs
  the same to the user - i.e. their shape - but their codepoints or
  sequence of bytes interally may differ from what the programmer expected.
