Hi, Simon Thank you for your reply and concern. As I said on my last email, my project is the software working on an embeded device. The CPU of the device is only about 500MHz. Performance of the system is limited, and business is changing rapidly. At the beginning, I want to try the OSGI module, and I eventually gave up because of it's strong dependence on Java. Then, I found the SCA Native. Good scalability and language independence of SCA is very attractive. But I have the trouble with the long call path from ComponentContext--Proxy--Wrapper to ServiceImpl and the time cosuming in the locateService(), invokeService(). I wonder if the SCA provide "native function call" policy , like OSGI, in some cases. If not, will consider it? Any ideal, wish your reply. Jeffery
