serviceMix 4.4 does not support ODE any longer, what is the alternative way to do orchestration?

[cdj0579 <cd...@gmail.com>]

hi everybody,
I am new to serviceMix, i have downloaded serviceMix 4.5.1 a couple of days ago, and i tried to install ode in serviceMix using the command 
features:install ode
but it tells me this message:
Error executing command: No feature named 'ode' with version '0.0.0' available
and after i googled many webs,i got a news that 
"Fuse ESB 4.4 does not support Apache ODE. The latest version of ODE is not compatible with Fuse ESB."

so if serviceMix 4.4 does not support ODE any longer, what is the alternative way to do the web service orchestration,
how about "bpel-g"? is it a good choice? or any other choice?

sorry for my broken english,i wish you could understand what i said.
Any help will be appreciated.
