Hi experts,
Thanks Andrew. adding a -noExit equivalent to my argument prevents my
system doing an automatic System.exit(0) on its own. Thus my POJO main
method running:
org.eclipse.core.launcher.Main.main(launcherArgs);
can have control after my App A has been run.
However, now my problem is how to return an result object from my App
A. org.eclipse.core.launcher.Main.main(launcherArgs) and org.eclipse.equinox.launcher.Main.main(launcherArgs)
does not have return type. If my app A which implements
org.eclipse.core.runtime.IPlatformRunnable does return an result object
in its public Object run(args) method, how do I retrieve it?
I tried cutting over to use EclipseStarter:
BundleContext context =
EclipseStarter.startup(launcherArgs,
null);
Object appResult = EclipseStarter.run(null);
However, I think I am not able to use the same configuration parameters
as before:
!ENTRY org.eclipse.osgi 4 0 2009-01-09 16:02:58.719
!MESSAGE Bundle org.eclipse.core.runtime@start not found.
!ENTRY org.eclipse.update.configurator 2009-01-09 16:02:58.859
!MESSAGE C:\pathTo\plugins is not a valid plugins directory.
Any idea?
Regards,
Tom

That main method will end up calling
System.exit unless you define a system property "osgi.noShutdown".
You should instead call
org.eclipse.equinox.launcher.Main#run(String[]).
(ie new Main().run(args) ).

Hi experts,
I have successfully my app A from another main POJO class like the
following:
public static void main(String[] args) {
String[] launcherArgs = {
"-configuration",
"C:\\pathTto\\configuration",
"-install",
"C:\\pathToIntall",
"-DJavaAgentLogConfigFile=C:\\pathToLogConfig\\log4j-commandline.xml",
"-application",
"org.my.Application",
};
org.eclipse.core.launcher.Main.main(launcherArgs);
}
The above requires the use of startup.jar's
org.eclipse.core.launcher.Main.main.
However, I notice I do not have control once I called Main.main. I do
not
have a way for my App A to return the control to the calling main java
file. I tried throwing an Exception in my app A to see if it will
bubble
up to the POJO main method, but it does not. I cannot use
System.exit(0)
since it terminates the whole JVM. snippet:
try {
org.eclipse.core.launcher.Main.main(launcherArgs);
} catch (Exception ex)
{
System.out.println("I am done with app A");
}
in app A's terminate method:
terminate() {
System.out.println();
//System.exit();
throw new RuntimeException("I am done. get me out of here");
}
What is a better way to achieve this? Bascially I want to run App A
which
through eclipse and use osgi from another program. Once App A is done,
it needs to terminate and return control to the my POJO.

Tom

I would recommend that you launch app A in a way
that is
consistent with the normal launch of eclipse. By that I mean use a
configuration
folder with a config.ini that is the same as if you are launching your
application with the eclipse.exe. The config.ini configures a set of
bundles
into the framework for your application. You should be able to do
something
like this
String[] equinoxArgs = { "-console",
"-noExit",
"-configuration"
"/path/to/configuration",
"-application",
"myApp.Application"};
BundleContext context = EclipseStarter.startup(equinoxArgs,
null);
Object appResult = EclipseStarter.run(null);

Hi experts,
I am new to equinox so please excuse me for some obvious/stupid
questions. However, I am still trying to wrap my head around this
module
system.
I am tasked with integrating an existing application A that is build
using bundles and equinox osgi in eclipse into another standalone Java
program B that will be traditional jar based program. I would like to
invoke the Equinox OSGi system to load these bundles/packages in the
standalone Java program through code and execute the main method of the
app A through program B.
My setup is as follows:
/plugins/ all the bundles that app A requires are here.
also app A has a main bundle here
I can use Eclipse Application run option to launch it or comandline
"java -cp startup.jar org.eclipse.core.launcher.Main -
application myApp.Application ..."
However, I am exploring the option to launch app A with another
existing
java program B. As a prototype, I am writing a plain POJO with main
method:
public static void main(String[] args) throws Exception {
String[] equinoxArgs = { "-console", "-noExit"
};
BundleContext context = EclipseStarter.startup(equinoxArgs,
null);
String pluginDir = "file:C:\\work\\";
String commonJarName =
"org.eclipse.equinox.common_3.2.0.v20060603.jar";
String configJarName =
"org.eclipse.update.configurator_3.2.2.R32x_v20070111.jar";
Bundle commonBundle = context.installBundle(pluginDir
+
commonJarName);
Bundle configBundle = context.installBundle(pluginDir
+
configJarName);
configBundle.start();
String jarName = "fetchlets.jar";
String directoryPath = "file:C:\\work\\plugins\\";
String locationStr = directoryPath + jarName;
Bundle bundle = context.installBundle(locationStr);
bundle.start();
}
However, my bundle fetchlets.jar cannot be started because, the
configurator bundle does not auto-discover all the required bundles in
the plugins directory. Can someone help me figure out if I can tell the
EclipseStarter to auto-load all bundles at a specific locations?
Or is there another approach I can use that is very similar to the run
options in Eclipse where setting the platform will suffice to load all
the plugins automatically?
I have been looking at:
