runSync or call directly

[ian tabangay]

Hi. If I have a service written in java, why or why should I not call
another service (also written in java) directly?

-- start code --
public static Map serviceA(DispatchContext dctx, Map context) {
  ...
}

public static Map serviceB(DispatchContext dctx, Map context) {
  ...
}
-- end code --

For example, to call serviceB from serviceA, is it more advisable to access
it via
  dispatcher.runSync("serviceA", context)
or can I just call it directly like so:
  serviceB(dctx, context)


Thanks

Always use runSync: there is a small overhead but several advantages,  
one the most important ones is that you just refer to the service  
definition and not on the actual implementation details (Java method,  
Minilang method etc...).

Also direct Java calls are not ECA aware and this is a very important part of OFBiz : its business workflow.
