I installed felix scr bundle into my host osgi application and tried to
obtain a list of active services by visiting a controller of my spring
application which calls osgi code and it threw the following error:
| Error java.lang.NoClassDefFoundError:

It seems like felix scr interferes with spring loaded? Is it possible to
avoid this?
Thanks

Neil,
bundle is active, but I dont have any DS implementation bundle
installed...I thought the framework itself contains the implementation.

Dirk: I don’t think Artem was asking about activation of the
component, he has a problem with service registration. So whether the
component is immediate or delayed seems to be irrelevant.
Artem: there are a few things you need to check. Is your bundle
active? Do you have a DS implementation bundle (such as
org.apache.felix.scr, or org.eclipse.equinox.ds) installed and active?

Try to add immediate=“true” to your component definition. This
should result in something like
<?xml version="1.0" encoding="UTF-8"?><components
xmlns:scr="http://www.osgi.org/xmlns/scr/v1.0.0";>
<scr:component immediate=“true”
name="ru.multicabinet.gateway.ExampleDS">
<implementation class="ru.multicabinet.gateway.ExampleDS"/>
<service servicefactory="false">
<provide interface="ru.multicabinet.gateway.SimpleI"/>
</service>
<property name="service.pid"
value="ru.multicabinet.gateway.ExampleDS"/>
</scr:component>
</components>
and causes the component to be started immediately after it has been
registered.

Hello,
I want to include more than one service into a bundle, so it seems
like I have to make a use of declarative services.
I'm building a test bundle with maven + maven-bundle-plugin and
generating the ds descriptor with maven-scr-plugin, so it looks
like this:
<?xml version="1.0" encoding="UTF-8"?><components
xmlns:scr="http://www.osgi.org/xmlns/scr/v1.0.0";>
<scr:component name="ru.multicabinet.gateway.ExampleDS">
<implementation class="ru.multicabinet.gateway.ExampleDS"/>
<service servicefactory="false">
<provide interface="ru.multicabinet.gateway.SimpleI"/>
</service>
<property name="service.pid"
value="ru.multicabinet.gateway.ExampleDS"/>
</scr:component>
</components>
After installing the test bundle into my osgi container I'm trying
to get a list of all services in the test bundle by calling
bundle.getRegisteredServices(), but it'd always return null.
What I'm doing wrong? Maybe I should use ServiceTracker to obtain
a reference to ds service?
Thanks
