Re: [equinox-dev] FW: Debugging Equinox bundles (not in Eclipse)
|
Should work; I've done this myself from Java code (both 3.2 and 3.3).
What it would look like is:
java -classpath org.eclipse.osgi_.....jar org,example.StartEquinox
If you run the -console, do you get the osgi> prompt at the shell? In
which case, what shows up when you do e.g. 'ss' or 'diag 1' or
whatever the number of your bundle is?
You might also want to try "-console","1234" and then doing 'telnet
1234' to get to the console; that would rule out any in/out stream
problems. You might also want/need the -noExit, in case you're seeing
it startup/shutdown almost immediately.
Lastly, is it possible that the bundle is already present, and because
it's got the same version number and URL, it's not actually doing an
update? In other words, it's quite likely that the *first* time you
did it, you installed the bundle w/o the manifest entry
'Import-Package', and then although you changed it the 2nd time,
because you've not changed the URL/version, it's using the old one.
You could fix this by (in the console) doing an 'uninstall 1', or
bumping the version number, or using a different URL/symbollic name.
From the JavaDoc (well, draft at
http://help.eclipse.org/help31/index.jsp?topic=/org.eclipse.platform.doc.isv/reference/osgi/org/osgi/framework/BundleContext.html):
1. If a bundle containing the same location string is already
installed, the Bundle object for that bundle is returned.
In other words, it doesn't actually do an update, it just gives you
the bundle back again.
bundle.update() would ensure that it's up-to-date.

Thanks Alex. Not the problem, I'm afraid - I've got the import in the
manifest and I'm using 3.2.1 anyway (I've tried without the import too).
Maybe I'll try 3.3. I think it's a classloader issue that I hope can be
fixed by one of the many properties or cmd line args you can start equinox
with, but I've no idea which one(s).
(Nice presentation at the JSIG yesterday BTW)

You've probably got
Import-Package: org.osgi.framework
missing from your Manifest. Eclipse 3.2 didn't used to barf at that,
but Eclipse 3.3 does. (It's basically a fixed bug)
