Hi, around your question, I may suggest the samples/calculator to you. It is very easy to enjoy. Since your scenario is not clear, I can not write more info here. Any way, samples/calculator is to be used in one JVM, if you are working in a distributed environment, I may suggent you something more, it depends on you. Good Luck.

It seems that you want implement some mediation logic, am I right? You could define a generic interface or take advantage of the "any" interface (org.apache.tuscany.sca.interfacedef.Interface, if isDynamic() returns true). > > is there any simple example for this scenario? > > In the Tuscany samples, such as bigbank, it seems to me that composite > service needs to have knowledge about the component service they are going > to reference. but in my case, I want all component to be generic, and be > able to dynamically compose by defining the composite file of what > components to use. > What are the criteria for your composition? SCA spec defines the wiring between a component reference and component service by the interface compatibility. Components can also be autowired by the runtime. Do you just want to programatically wire the components together or do you expect the Tuscany runtime to wire things based on the metadata (such as business semantics, service-level agreement)? > not sure whether the SCA is a better way to do this? any idea or comment? > > -- > regards; > > Peizhao > > > --------------------------------------------------------------------- > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------- Looking for earth-friendly autos?
