Re: [rules-dev] Question about kie - api & kie - internal (OSGIactivator)

I should have a look to the code as I don't know for the moment which one we would like to expose ?

Anyway the question is more for the moment "Which OSGI services would we like to expose on OSGI platform" instead of How to achieve that ?

But I think I never had the necessity to inject beans in many years of development with OSGi. Injecting simple components and services fitted well all my needs. :) And the best from DS is that it is smart, small and fast. As Blueprint, CDI and DS uses xml we can provide all. But I don't know If there is a way to choose only one at runtime... I mean, what could happen in a system where we have both Blueprint and DS active? 2013/3/28 Charles Moulliard <ch007m(a)gmail.com <mailto:ch007m@gmail.com>> There is nevertheless one advantage of Aries Blueprint over Declarative Service which is : "Unlike Declarative Services, Blueprint can inject not only OSGi services, but also managed beans, i.e. plain old Java objects. Managed beans are local to the current component and cannot be injected into other components. Each Blueprint-enabled bundle has its own Blueprint context with managed beans and OSGi service references. The contexts of different bundles can interact by injecting services published by another bundle."

Declarative Service is rather new top of karaf (http://sully6768.blogspot.be/2012/09/scr-components-with-karaf.html) As a consumer you can still using both blueprint or BundleContext.getService() to reference the services. What I found good in both Blueprint and DS is that they ensure the component/services lifecycle and we could still use Configuration Admin with them. The problem with blueprint is that is not default installed in most distributions while DS is. Is DS installed by default in Karaf? 2) For poi-ooxml, we should use the ServiceMix bundle (http://repo1.maven.org/maven2/org/apache/servicemix/bundles/org.apache.se...) until they provide a OSGI bundle of POI. Unfortunately this bundle don't export the package needed. it wraps the poi.jar but not poi-ooxml. org.apache.poi.ss.usermodel.Workbook.class :( On Wed, Mar 27, 2013 at 1:53 PM, Cristiano Gavião <cvgaviao(a)gmail.com <mailto:cvgaviao@gmail.com>> wrote: I won't change that code for while... It is still be there until you decide to move it to the new one. ;) Btw, I have two questions: 1)what do you think about to use Declarative Services to register the services instead do it manually at activator ? 2) how are you dealing with poi-ooxml dependency in drools-decisiontables? there is no osgified jar for it... 2013/3/27 Charles Moulliard <ch007m(a)gmail.com <mailto:ch007m@gmail.com>> Hi Christiano, I prefer that first we finalize the OSGI bundles (drools-decisiontables, drools-jpa, drools-jbpm, ...) before changing pax-exam code which is working and also used by Apache Camel/Karaf projects ;-) Regards, Charles On Wed, Mar 27, 2013 at 1:44 PM, Cristiano Gavião <cvgaviao(a)gmail.com <mailto:cvgaviao@gmail.com>> wrote: Hello, I already look at it.
