Call OSGi services programmatically

Hi

With SpringDM/Gemini it is possible to call a service programmatically like this: 

 Class<ValueProcessor> cls = ValueProcessor.class;
 OsgiServiceProxyFactoryBean factoryBean = new OsgiServiceProxyFactoryBean();
 factoryBean.setBundleContext(bundleContext);
 factoryBean.setInterfaces(new Class[] { cls });
 factoryBean.setFilter(filter);
 factoryBean.setContextClassLoader(ImportContextClassLoader.CLIENT);
 factoryBean.setBeanClassLoader(cls.getClassLoader());
 factoryBean.afterPropertiesSet();
 ValueProcessor valueProcessor = (ValueProcessor) factoryBean.getObject();

How 
can one create the proxy instance of the service with Aries?

+1 on DM
The real beauty is DS/DM/BP/Peaberry etc all work on top of the service
registry, so you can mix higher level frameworks that fit best.

Hi

You might want to consider the Apache Felix DependencyManager [1]

This of course has nothing to do with OSGi Blueprint or Spring/DM. It is just a programmatic front-end to simplify servie registration and DI.

Hi Martin,

Aries doesn't have a programmatic API for creating blueprint managed beans, references or services. I assume that XML isn't appropriate for your use case?
