Hi ,Guillaume, My target is to use only one BP implementation in karaf, and unfortunately i choose the springdm which
is not used by karaf now, I need BP implementation to be exclusive in one container because i don't want one serivce to be registered twice. Looking inside the karaf related module, i found there were several places where karaf denpended on gerinimo BPIMP tightly: 1) As you said there are two NamespaceHandlers which implement gerinimo's NamespaceHandler 2) The ext namespace(org.apache.geronimo.blueprint.ext.ExtNamespaceHandler) such as "property-placeholder" which is used by karaf-shell-console and karaf-admin, maybe by more other models. Maybe i can provide NamespaceHander based on springdm for above gerinimo specific namespace handlers , but it's not a nice way. I don't catch your mind to provide a neutral way. neutral proxy NamespaceHandler implementation or neutral namespace declaration instead of existed ones?
