Spring DM - OSGI service register and use in the same bundle
Hi,
I try to register an OSGI Service and use it in the same bundle but
get an unsatisfied dependencies error.
Is it allow to do that ?

I try to do that because I have issue with Hibernate + JPA + Spring Tx
regarding to transaction commit who does not occur when using separate
bundles. This is why I created one bundle to see if the same error
occurs or not. By the way, If I refer directly to the bean instead of
the osgi:reference, everything works fine

TBH I've never took a look into springs source to know y, but it doesn't like it
if you import in the same bundle you export it. Simple solution is to split into
to different bundles (as jb suggested), or use the bean txManager directly
instead of the service.
BTW, it doesn't matter if you define you beans in one or 10 .xml files in one
bundle. Spring "concats" them first and start to load them afterwards.
kind regards,
andreas

Re: Spring DM - OSGI service register and use in the same bundle
Posted by Jean-Baptiste Onofré <jb...@nanthrax.net>.
Hi Charles,
You should split into two different bundles. I think that the interface
is not yet bound when the reference tries to resolve it.
To be honest, I've never tried to use a service reference to another
descriptor file in the same bundle (I defined all in the same blueprint
descriptor, so no need to use a service reference internally).
Regards
JB

Re: Spring DM - OSGI service register and use in the same bundle
Posted by Guillaume Nodet <gn...@gmail.com>.
Spring-DM and blueprint do not support well such a construct unless
the referenced service is an optional dependency.
The reason is that dependencies must be satisfied before the
application is started, so it waits forever.
You need to either use an optional dependency or directly reference the bean
<bean id="PROPAGATION_REQUIRES_NEW"
class="org.apache.camel.spring.spi.SpringTransactionPolicy">
<property name="transactionManager" ref="txManager"/>
<property name="propagationBehaviorName"
value="PROPAGATION_REQUIRES_NEW"/>
</bean>
