I am Using Eclipse Virgo/Gemini Blueprint and have an Interface with multiple implementations:
Implementation 1:
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.osgi.org/xmlns/blueprint/v1.0.0 http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd">
<bean id="MyID1"
class="ImplementationCLass1">
</bean>
<service ref="MyID1"
interface="MyInterface" />
</blueprint>
Implementation 2:
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.osgi.org/xmlns/blueprint/v1.0.0 http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd">
<bean id="MYID2"
class="ImplementationClass2">
</bean>
<service ref="MYID2"
interface="MyInterface" />
</blueprint>
Implementation 3:
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.osgi.org/xmlns/blueprint/v1.0.0 http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd">
<bean id="MyID3"
class="ImplementationClass3">
</bean>
<service ref="MyID3"
interface="MyInterface" />
</blueprint>
And a Client:
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.osgi.org/xmlns/blueprint/v1.0.0 http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd">
<reference-list id="MyImplementations"
interface="MyInterface" />
<bean id="clientID" class="ClientClass"
init-method="startUp">
<property name="services" ref="MyImplementations"></property>
</bean>
</blueprint>
The startUp method is a simple method which iterates over the whole list and prints out a simple string (for testing purpose)
The Problem is if i install the client Bundle only two out of tree Services are in my List.
If i stop and start the Bundle again, all three Services are in my List.
Any ideas/sugesstions why?
Is it possible to tell Blueprint that the list MUST contain all Services matching MyInterface?
