Thanks, Neil !
I dont want to fix in a specific bundle. So, Im not sure about 'bad smell'.
:-)
Im implementing a kind of mechanism for automatic activation, given a
request to my component.
I have a mapping of ObjectX and if this object is resolved, all items of
dependence must be resolved as well.
*For example:*
<objectX>
<service1 service-spec="br.com.dhiego.ServiceOne">
<service2 service-spec="br.com.dhiego.ServiceTwo">
<service3 service-spec="br.com.dhiego.ServiceThree">
</ objectX>
No matter what happens, if my ObjectX is called, services 1, 2 and 3 must
be activated. For this, I need to check the bundles that provide these
services ("service-spec" tag, in xml) and then activate them.
Abs,
