Hello,
I have a small program which starts equinox using the EclipseStarter
class so that I can run some plugins in a standalone OSGI platform.
The code:
String[] equinoxArgs = {"-configuration",
"C:/equinox-test/configuration"};
BundleContext context = EclipseStarter.startup(equinoxArgs, null);
for(Bundle b : context.getBundles()) {
if(b.getSymbolicName().equals(bundleName)){
b.start();
}
}
I have org.eclipse.osgi in the classpath to use the EclipseStarter.
Furthermore I use org.eclipse.update.configurator and
org.eclipse.equinox.common to parse the plugins folder, ...
My problem:
-If I run the program inside the eclipse IDE, the starter starts up
equinox and loads all plugins, ... -> everything is fine.
-If I export the program as a runnable jar file and try to run it, the
starter does something but doesn't load the plugins, ... -> log file is
attached.
So, does anyone have an idea what could be wrong there?

Hi Tom,
thanks but I solved the problem. It is not possible to run equinox with
a large set of plugins from a runnable jar. The solution is to export
the classes as a standard java library and add the main class attribute
and the classpath to osgi to the MANIFEST header. Then the framework
comes up without problems.
I'm not sure why this isn't possible with a runnable jar file but the
error message says something about a problem with the storage. So I read
about this here:

Greetings,
Stanley
