 |

Hi everybody,
There is no problem to start an application on windows (at least for me).
How do you start an appication on Unix and on Mac?
Is ther few lines of code I can get like it is on windows?
I have a friend who has a Mac. I sent her an application but her Mac does
not know how to start it . I found this
--------- start.sh -------
#!/bin/sh
java -cp . myApplication
--------- end start.sh -------

Thanks for your attention.

You haven't provided anywhere near enough information to give a
definitive answer.
The above command line only works if "myApplication.class" exists in the
directory where it's executed. That's true on Unix systems. And the
modern Mac OS X system is based on BSD, so that it can work there as
well if your friend is willing to go into the Terminal program and type
the command at the right location. Most Mac users, however, aren't
familiar with this environment.
You need to provide more details. Better still, you should package up
your application, perhaps putting it into a jar file. I can assure you
that her Mac will know how to launch that if it's designed to be self
contained -- though it won't be all that pretty.

[ code snipped ]
What's in the code isn't relevant to the question you raised.
Your original question asked whether "java -cp . myApplication" would
work. It won't unless myApplication.class is present in the directory
where this command is issued.
If the application in question is inside a jar file (signed or not) with
a proper manifest that identifies its main class, then double clicking
works on Windows and in Mac OS X. But because of the difference in the
Mac's interface, it won't look too pretty.
If your Mac-using friend is comfortable enough to use a command line,
she could instead use "java -jar JarFileName.jar" if it's got a proper
manifest. If not, then the name of any class inside with a proper main
method can be used with "java -cp JarName.jar ClassName".
What you might notice is that what I just described is *precisely* the
same as it works on Windows systems.
When you install Java on Windows, the installer usually gives you a file
association for jar files that causes "javaw -jar filename" to get
invoked so that double-clicking works -- except it'll fail if there's
not a proper manifest. The very same is true in Mac OS X.
Other Unix systems (including Linux) may or may not have a graphical
mechanism like the double-click available, depending on configuration.
The command line technique should work equally for all.

Somewhat off-topic, the messages that your code is sending are not compliant
with RFC 2822, because they do not contain the required "Date:" header.
Your code is also not compliant with RFC 2821 (SMTP) as the "email address"
that you have specified
For MIME, you also need more than just the "Content-Type:" header. You need
at least:
MIME-Version: 1.0
and
Content-transfer-encoding:
Furthermore, if your message contains eight bit data (very likely, if you're
using accented characters), you will need to encode it to be seven-bit,
because SMTP only guarantees seven-bit data transmission. The two popular
methods of encoding are QP (quoted-printable) and base64.
I'd personally recommend that you use something such as JavaMail instead of
attempting to do this all yourself.
Cheers!

@wagner.videotron.net:
Because the particular mail server that you're using is obeying one of the
prime principles of the Internet, "Be liberal in what you accept and
conservative in what you produce.", and is accepting your broken email,
which you should not be producing.
Not all mail systems will necessarily be so accepting of broken emails such
as yours, therefore it is highly recommended that you follow the published
Internet Standards documents to the absolute best of your ability to do so.
This will insure maximum interoperability.
