javax.mail, classpath and classpathx

[Øyvind Harboe <oyvind dot harboe at zylin dot com>]

Has anyone had any luck in getting javax.mail classes compiled from GNU
classpath?

Am I on the right track here?


I need to send emails where the subject and body are UTF-8 encoded, so
as to support the full unicode charset. My Java test program using Suns
classes work fine, but I'd like to use GCJ since the program that needs
this is a Windows C++ application where it is completely out of the
question to bundle a Java JRE for various reasons. I didn't find any
C/C++ libraries out there than can interface to SMTP *and* speak
unicode/wchar_t properly, so this seemed like a good excuse to play
around with GCJ.

Here is an account of my pitiful attempts:

- I fetched the files for classpathx from CVS and tried to compile.
After some fiddling around, I discovered how to get ./configure + make
going and I ended up with various .jar files. First I tried and failed
this under CygWin, but then I remembered my Linux machine in the closet
and voila!
- Alas, it appears that GCJ classpath compilation does not include the
classpath/inetlib classes. My attempts to compile classpath failed.


There was recently a discussion which was along the same lines:
