OSB ALSBConfigurationMBean importing configuration using java

Question

I am trying to import configuration sbconfig.jar in OSB using java for automated tests. Before that I implemented FindAndReplace operation using Orcale help in java. But in сase importing configuration from the same Article, when I run presented code - I get an error.

What I am trying to do

1. Connect to OSB(Oracle Service Bus 11.1)
2. Read file
3. Create session
4. Import prepared file
5. Activate session

On fourth item i got an error:

Cannot import to deployed configuration

Maybe someone has already implemented such a thing?

I would be grateful for help
