Hi Joel and everybody, I'll try to explain a little better.
First, it's not a problem with Java (I haven't tested any java program 
on this issue), but something I first noticed
when saving files with my Java IDE  (programming environment), working 
from windows on [convoluted] samba share.
(I'll explain the [convoluted] part later just for fun, but it's 
irrelevant to the problem)

The setup is:
WINPUTER sharing a dir called MyWinShare
LINUXPUTER smbmount[ing]  //WINPUTER/MyWinShare  on the local linux dir 
 /mnt/winputer/shareit
LINUXPUTER  sharing /mnt/winputer/shareit  through samba to the rest of 
the LAN
WINPUTER programs trying to create files on the "shareit" share that 
LINUXPUTER publishes (which is
actually on WINPUTER to start with, but it doesn't matter!!)


When creating a file from Wordpad which is a Microsoft Windows program 
(nothing to do with java)
the files are created with ALLCAPS, no matter how you entered them in 
the file save dialog box.
When creating files from Notepad (M$ program) it respects the 
capitalisation.
When using MS Explorer to "drag and copy" a file called foobar.txt, the 
copy becomes "COPY OF FOOBAR.TXT"
When just "dragging and moving" it keeps the capitalisation.
When creating a new file or folder with the windows explorer (right 
click, New, Folder, text document, etc....) or renaming
a file, it respects capitalisation.

<new test>
I map the "shareit" share to a drive letter, say P:
from a DOS prompt I do  "P:\> dir > eEeEeEe"  and it keeps capitalisation
</new test>

Now, nothing like this happens from Windows when writing to a regular 
share that ends up in a normal linux dir (not one that
is smbmount[ed] back to a a Windows machine.
In the same manner, everything is fine when, from the linux prompt I do 
a "ls > eEeEeEEeeeE"  inside the smbmount[ed] directory.
A file with correct capitalisation appears in MyWinShare.

But mix the two together and KAPUT ALL CAPS!!!!  (from some programs, 
not others!!!)

(below is my original post where I explain some of the tests I did with 
codepages and character sets which yielded no change to
this behaviour)


<explanation on my convulted original setup>
In my home linux computer I do:
ssh -2 -C -f -N -g -L 13900:officePC:139 officeLINUX
So I create this SSH tunnel from local linux port 13900 to port 139 in 
my office PC

Then, also in my home linux I do:
mount -t smbfs -o 
username=barspi,port=13900,ip=127.0.0.1,workgroup=OFFICEDOMAIN,fmask=777,dmask=777  
//OFFICEPC/MyShare  /mnt/office/officepc/MyShare/

So now the home linux dir is mounted to my office PC share
I share this local dir with samba and I can access my office PC from any 
PC inside my home network.

Before anyone says it... yes, I know there are things called VPN's and 
all that... but I haven't had time to download/study those
packages and this way let me learn loads of stuff about SSH, samba, etc. 
and it was fun :-)

Thank you all!!
