Hello java coders,
I've just built my first Swing app in eclipse, exported it as JAR and
now find a problem:
When running it out of eclipse, I can configure VM arguments that always
will be applied automatically - in my case it is a "-Xmx512m", giving
the VMm more heap space - my app really needs loads of memory.
But when I want to give away the JAR, will then every single user only
be able to start the app via the command line, specifying the switch
manually, or is there any way to include this VM option into some file
inside the JAR, so the app can be run by simply double clicking it
(under Windows, that is)?
Any comment welcome,
best regards,
Roman.

Hi Roman. This is more of a Java question and you'll probably get a
better answer on one of the Java-specific forums. That said, I believe
that you need to create some sort of application launcher that sets the
command-line arguments. In the past, I've done this with a shell script.
To be honest, it's been a while since I've had to do this sort of thing
and there may well be a better way to do it now.
Good luck,
Wayne

You add the options to the java command when you invoke your bat file
that has the jar file. Ex.
java -Xmx512m -jar your.jar
Thanks in Advance...
