Is it possible to property placeholders in blueprint configuration file

[Raj Saini]

Hi,

I am new to Aries and exploring blueprint and successfully wired my 
services. One of the bean property I use needs a host and port and these 
values can change during final deployment of the application. I am 
thinking of using system properties. I have looked around but could not 
find any documentation to use property placeholders in blueprint xml file.

Is it possible to use properties placeholders in blueprint xml file? Or 
is there a better way of achieving this? ConfigurationAdmin also crossed 
my mind but did not explore it yet. Is it possible to use 
ConfugrationAdmin service with blueprint?

Regards,

Raj
