Tuscany does not support using classes in the @Service annotation
-----------------------------------------------------------------
Key: TUSCANY-1629
URL: https://issues.apache.org/jira/browse/TUSCANY-1629
Project: Tuscany
Issue Type: Bug
Components: Java SCA Java Implementation Extension
Affects Versions: Java-SCA-0.91
Environment: Linux
Was using Tuscany SVN revision 570353
Reporter: Mark Combellack
Fix For: Java-SCA-0.91
The current implementation of Tuscany does not support using a class in the
@Service annotation.
For example, if I have:
@Service(MyService.class)
public class MyService {
public String op1() {
return "op1 invoked";
}
}
The above example is valid from my understanding of the Java Common Annotations
and APIs specification because it says:
1628 The @Service annotation has the following attributes:
1629 • interfaces - The value is an array of interface or class objects that
should be exposed as services
1630 by this component.
1631 • value - A shortcut for the case when the class provides only a single
service interface.
The key phrase is in line 1629 "or class objects"
Tuscany throws the following exception:
