newbie question about Eclipse for Java [message #34174]

Hi.

I'm a C++ developer, trying to use Java for the 1st time. I tried
NetBeans and didn't like it so I tried eclipse and had a better
experience. I have a couple of questions about using Eclipse for Java.
Is this the right place?

My questions:

- How do I go into 'full-screen' mode?

- How do I make the status bar go away?

- Where do I find the eclipse user settings: the ones that are not
specific to the computer and can be copied to another installation of
eclipse. I want to try to keep the eclipses on my notebook and my
desktop synced. Are these in the .metadata folder tree?

- I have a java project for which I can't figure out where the
executable is. It's not in the project's folder tree. I can run the
program from within eclipse and it works fine, but where might that jar
file be?

thanks,
Tom.

The closest you're going to get is by double clicking the title tab of
any currently selected editor or view.

Don't think that's possible. Or at least easily accomplished from a
user perspective.

Most of the user settings are stored in the .metadata directory.
However a better way to share preferences is to export them as a file by
opening the Preferences dialog and hitting the Export button at the bottom.

Java binaries do not have to be packaged in a jar in order to be
executable... simply running the .class file that has the main() method
is the basic way of executing a Java program. E.g. java MyClass (in the
directory where MyClass.class resides) If you wish to package your
program in a jar, see the Jar file Export wizard (File->Export... and
choose Jar file)

Hope this helps,
- Jeff

Won't that just cover the preferences?
I want to get things like the 'run configurations' too. Or are those
stored in the project files?

Ah, that explains my confusion.
Thanks for the info,
Tom.

Launch Configurations can be stored in the project directory. If you're
editing a launch config, select the Common tab and you can make it a
"Shared" config and choose a location in your workspace to store it.
I usually create a .eclipse directory that gets checked in to CVS and
store them in there.

HTH,
Eric
