RCP/Equinox Console App Launcher on Linux [message #96580]

Hi,

how can I run the eclipse launcher (within an exported rpc product of eclipse 3.3) on a linux system without gtk/window management (its just a console application)?
The application offers an input stream, so with the -console option it gets confused with the input stream of the interactive osgi interface.

One problem is also, when an osgi/rcp error occurs, the platform wants to pop-up a message dialog: without window-management the java-vm crashes.

Is there maybe a eclipsec.exe equivalent for linux?

Thanks in advance, Stefan

I seem to recall that there's an enhancement request to do that. However, you can launch java -jar plugins/org.eclipse.launcher.jar or some such instead of eclipse to bring it up without the UI. All the launcher executable does is create a VM and dialog window for splash screens etc. that you can run with the java -jar without needing (though you might need to have -noSplash as well).

For just running the pure application java -jar plugins/org.eclipse.equinox.launcher_XY.jar works fine.
For osgi troubleshooting i have the log files or may can use the -console telnet-port option to avoid stream confusion

thanks

There is an option "--launcher.suppressErrors" that turns off the error
messages, however the launcher is statically linked against the gtk libraries so
they are required on the machine even if no graphics are being done.

See https://bugs.eclipse.org/bugs/show_bug.cgi?id=201414

We use IApplication and .product to implement our server applications. The Linux/Solaris servers of our customers usually don't have any WS and we have no possibility to install them.<br/><br/>Currently, we live with the following workarounds<ul><li>we have a post-product-export-script that changes the file structure (because it is different without launcher)</li>
<li>we manually copy the launcher.ini settings into a manually coded start script (and hopefully don't forget it if we change the launcher settings in the .product)</li>
<li>we manually code the restart logic in the start script (hopefully, the exit codes will never change)</li></ul>
<br/>Not all too complicated but also not as straightforwarded as it could be (at least in my vision ;o)). Any plans when this launcher (with updated product export) could be available?

Cheers, Stephan

I haven't actually started working on it yet, but it is conceivable that it
could be in M3
( http://www.eclipse.org/eclipse/development/eclipse_project_p lan_3_4.html)

No promises yet though :)

Hi all,

we have our application installed on a unix operating system without any window system (gtk/motif) and start it by calling "java -jar org.eclipse.osgi_3.3.0.v20070530.jar". This works fine.

On certain conditions (e.g. after an update), the application should be restarted and therefore we return IApplication.EXIT_RESTART in the start method's implementation of IApplication. IApplication.EXIT_RESTART would be Integer(23) and the idea would be to check for this exit code in the starter script and restart the application. However, the JVM always exits with exit code 0.

Browsing through the EclipseStarter class one can see that the main class does not set any exit code (unlike e.g. the main of org.eclipse.equinox.launcher.Main).

My question now is how - if at all - it is possible to retreive an exit code other than 0 by starting an application with "java -jar org.eclipse.osgi_3.3.0.v20070530.jar". Or does the exit code in this case have to be set programmatically?

Cheers,
Christian

The problem is, that the exit code is passed around via SystemProperty "eclipse.exitcode" (see org.eclipse.equinox.internal.app.EclipseAppHandle.run() and org.eclipse.equinox.launcher.Main.run() (BTW, contain duplicate constants for "eclipse.exitcode"!)). If the application is started via -jar osgi.jar, it looks like the exit code is not handled and thus is not available to the shell script.

A workaround is to write a simple wrapper around EclipseStarter and start this one instead of -jar osgi.jar.

import org.eclipse.core.runtime.adaptor.EclipseStarter;
public class Main {
	public static void main(String[] args) {
		String exitCode = "-1";
		
		try {
			EclipseStarter.run(args, null);
			exitCode = System.getProperty("eclipse.exitcode"); //$NON-NLS-1$
		} catch (Exception e) {
			e.printStackTrace();
		}
		
		System.exit(Integer.parseInt(exitCode));
	}
}

This solution works for us but we don't feel too comfortable with it (using internal system properties). We are not sure if there is a better approach that we have missed...

A launcher without dependency on WS would help a lot :o)

Cheers, Stephan

Please find launcher binaries attached to
https://bugs.eclipse.org/bugs/show_bug.cgi?id=201414.

They are capable of running both with and without a WS present. More testing is
required before releasing these changes, I would appreciate people giving them a
try in both a normal eclipse and a headless app.

I am faced with the same problem. I want to create a console application and run it in terminal. It is necessary to parse command line parameter with in the application too. What could I do?
