Re: ConfigAdmin and OSGi Blueprint

[lb <lb...@gmail.com>]

Hi,
I've used the suggested approach to inject the whole map:

<cm:property-placeholder id="myConfig" persistent-id="my.service.pid">
</cm:property-placeholder>

<bean id="my.bean.id" class="my.bean.Class">
    <property name="config" ref="myConfig"/>
</bean>

But the injected object is an instance of CmPropertyPlaceholder: is there a
way to inject a plain Map/Dictionary/Properties ?

Thx
