Re: [equinox-dev] Where can I find equinox docs? 
Hi,

I'm not sure if this will help, but you can take a look at this link
for information on various options for running eclipse:

http://help.eclipse.org/help30/index.jsp?topic=/org.eclipse.platform.doc.isv/reference/misc/runtime-options.html

These options are what can be placed in the config.ini file (or passed
in to eclipse as command line arguments).  You may find the answers to
some of your other questions in the osgi specification (see
http://osgi.org).

As for your debugging question, you might try creating an Equinox OSGi
Framework runtime configuration and see if that works.  Or, you could
create a new Java application runtime configuration and try that (in
which case you would specify the EclispeStarter class from your
project as the main class, and you would want to specify -console as
the argument).

Hope that helps,
Arjun

Thank you for your reply John.

Well, the website (www.elipse.org/equinox/documents/) seems not to
provide the infos I need ...
I want to investigate equinox as an standalone osgi implementation.
The org.eclipse.osgi_3.2.0.v20060601.jar (delivered with my Eclipse
version) works fine standalone, as described on the equinox quickstart
guide, but I want to debug the framework. For that reason, I checked out
the 'org.eclipse.osgi' code tree from the CVS server
(dev.eclipse.org/cvsroot/eclipse), created the provided eclipse project
and tried to debug it. Using the predefined Debug configuration of the
project (DevFramework), throws some exceptions on startup:

    at org.eclipse.osgi.baseadaptor.BaseAdaptor.<init>(BaseAdaptor.java:95)
    ... 7 more

It seems that the framework starts with an
org.eclipse.osgi.framework.launcher.Launcher class, which is different
from the Main-Class (org.eclipse.core.runtime.adaptor.EclipseStarter)
used in the org.eclipse.osgi_3.2.0.v20060601.jar file. I've tried to do
it as configured in the .jar file and took the
org.eclipse.core.runtime.adaptor.EclipseStarter as Main Class for the
project startup. Debugging failed then on storage initialization:

java.lang.NullPointerException

org.eclipse.osgi.baseadaptor.BaseAdaptor.initializeStorage(BaseAdaptor.java:124)

org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:207)
    at
org.eclipse.core.runtime.adaptor.EclipseStarter.main(EclipseStarter.java:138)

I also found out, that even before 'initializeStorage()' the BaseAdaptor
constructor cannot get a valid 'storage' value, because there are no
StorageHooks present in the hookRegistry. But why, can you tell me what
is going wrong? Probably I am trying to accomplish the intended in a
wrong way?

So, again my question: how should I go about debugging equinox as
standalone osgi framework, and where can I get some knowledge about all
the stuff like different start configs, properties, hooks, storage
organization and s.o.

Vlad
