Accessing osgi blueprint property-placeholder across multiple
bundles
Hi
I have a question concerning this example :
http://camel.apache.org/properties.html#Properties-UsingBlueprintpropertyplaceholderwithCamelroutes
I wonder if these inlined proerties can be accessed across many bundles? IE
bundle A defines a property-placeholder and bundle B is able to access those
defined inlined properties
I haven't been able to get this to work properly, and I wonder if it is
indeed possible?
If anyone has any knowledge of this I'd greatly appreciate it!
Thanks
Alan

Hi,
Yes, using system property is one solution, to use system property in blueprint file, you need use blueprint-ext but not blueprint-cm(blueprint-cm is for ConfigAdmin properties)
something like:
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
xmlns:ext="http://aries.apache.org/blueprint/xmlns/blueprint-ext/v1.0.0">
<ext:property-placeholder />
<bean id="myBean" class="com.company.MyClass">
<argument value="${com.company.myProperty} />
</bean>
</blueprint>
And you can use both blueprint-ext and blueprint-cm together.

If you use ServiceMix or Karaf, you can put your custom properties into
"etc/custom.properties" and use these placeholders in your bundle
properties file.
Than you have a central place for common/shared configuration data.
Best,
Christian

@Freeman-2
Hm, this isn't good to hear :(
Do you happen to know of any alternatives for this? I wish to share common
configuration across bundles with blueprint somehow

Hi,
No, I don't think so.
Per the Configuration Admin spec
Do not share the same persistent-id (PID) between multiple bundles or definitions, as only one of them will receive notifications. managed-properties relies on org.osgi.service.cm.ManagedService contract which mandates that each ManagedService instance must be identified with its own unique PID. Please see the Configuration Admin spec, specifically section 104.3 and 104.5
