Hi,
Here is another way to help your custom camel component not be polluted
by OSGi APIs.
If you custom camel component has the dependency of the OSGi service,
you just need to create a get/set method of that services interface in
your custom component.
Then you can inject the services into the camel component by use the
spring DM like this. and your camel component doesn't need to get touch
with any of the OSGi API like this.
<beans xmlns="http://www.springframework.org/schema/beans";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:osgi="http://www.springframework.org/schema/osgi";
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/osgi
http://www.springframework.org/schema/osgi/spring-osgi.xsd";>
<bean id="custom"
class="com.example.CustomerCamelComponent">
<property name="Services" ref="myServices"/>
</bean>
<osgi:reference id="myServices"
interface="com.example.osgi.Services" />
<!-- you can add your camel route here -->
</beans>

Hi All,
I have created a custom camel component. The endpoint for the camel
component needs a service which is exposed by another osgi bundle. I found
that there are couple of ways to do that:
Solution 1: (Using camel API)
-------------------
Use CamelContextHelper.lookup("class name");
This will internally have the following call trace:
SpringOsgiCamelContext.getRegistry()
PropertyPlaceholderDelegateRegistry.lookup()
CompositeRegistry.lookup() - Here a list of registries are looked into. I
can see 2 registries -> OsgiRegistry& ApplicationContextRegistry.
Solution 2: (Using Spring API)
----------------
Have a bean implement BundleContextAware, this will then result in injection
of BundleContext
which can then be used to look up a service reference and then the required
service.
As of now i have adopted solution 1 (using the camel API) as the class that
required the service was a custom camel endpoint.
Is this the right way to do it or are there better alternatives?
Best Regards,
Madhav
