Thanks JB, when the OSGI service invoked from XML DSL it worked and I got good response and I am not sure what I missed when I invoke OSGI service from java DSL.

Thanks, VKA ________________________________ Hi, Did you try to use # for bean ref ? I’m not sure it will work mixing blueprint and Java DSL, I’m pretty sure it works fully in blueprint.
