Re: [equinox-dev] Service component deployment fails into a running Equinox application
|
OK, this is not a bug.
I assume you are launching equinox outside of the IDE and then attempting
to install project folders from one of your workspaces into the framework.
When equinox is launched from the IDE (PDE) then extra options are passed
to equinox to inform it about development class paths of each project in
your workspace. You could try to use the -dev option or set the osgi.dev
configuration property depending on how you launch equinox (i.e.
osgi.dev=bin would add bin to the class path of every bundle, or you can
use a URL to point to a properties file that contains symbolic name keys
and class path values for each bundle you want to install from your
workspace).

Hello Guys,
Sorry, it was my mistake.
I realized that I did install the service provider plugin as a workspace
plugin (including the bin folder) and not as a jar file. If I install and
start the service provider as a plugin JAR file, everything is ok.
So it does not work like this:
osgi>install
file:/home/csaba/eclipse_distros/Indigo/workspace/osgi.example.service.implementation
But it does work like this
osgi>install
file:/home/csaba/tmp/plugins/osgi.example.service.implementation_1.0.0_20120209.jar
So I think, this is not a bug...
Thanks, anyway!

I would open a bug against Equinox->Compendium (at
https://bugs.eclipse.org/bugs/enter_bug.cgi?product=Equinox). This
sounds
like a bug and it would be helpful if you could provide your testcase
attached to the bug.
Thanks.

Hello,
No, I do not, but I also tried it with that without any success. Nor do I
with the 'refresh' Equinox console command. I always get the same
exception
stack...
Actually what I try to do is to provide a proof-of-concept Equinox
application that is dynamically/at-runtime extendable (through service
provider components) without the need to stop/restart the base
application.
But it's really strange that I don't have any problem with my bundles in
Apache Felix and SCR.
Perhaps do you know some other working solution for the requirement?
Many thanks, Csaba.

Do you have an optional import for the package name?
If you do, and that bundle starts first, then it won't be wired to the
package. If you start up the bundle containing the package first, then
start up the provider, it will resolve the list of optional imports.
Once
started, even if an optional package is added later it's not added to
the
existing running bundle's package list. If you do a 'refresh' on the
service provider, does the problem go away?
