Runtime ignores custom callback when using setCallback()
--------------------------------------------------------
Key: TUSCANY-2312
URL: https://issues.apache.org/jira/browse/TUSCANY-2312
Project: Tuscany
Issue Type: Bug
Components: Java SCA Core Runtime
Affects Versions: Java-SCA-Next
Reporter: Kevin Williams
The Java CAA spec states:
/**
* Lines 728-732
* <p>
* By default, the client component of a service is assumed to be the
* callback service for the bidirectional service. However, it is possible
* to change the callback by using the ServiceReference.setCallback()
* method. The object passed as the callback should implement the interface
* defined for the callback, including any additional SCA semantics on that
* interface such as its scope and whether or not it is remotable.
*/
I am getting the following error when I try to provide a custom callback using
ServiceReference.setCallback(). I appears that the runtime has injected the
client service as the callback rather then the user provided callback resulting
in the following exception:
java.lang.IllegalArgumentException: java.lang.NoSuchMethodException: No
matching method for operation callBack is found on class
