Hi, Yes your write.I am also confusing about it,after reading the documentation.And another thing is ,You declared two services in same application context is it not loading service two times. i.e first instatntiate the EaElementService implementation ,after that EaPackageService implementation and EaElementService implementation.That means EaElementService implemenation bean intstantiation takesplace two times,have you observed this ,if you are using same application context for more than one service?
According my understanding with out <sca:service> and <sca:reference> tags we can define spring beans as components; Thank you.
