耿韶光 commented on TUSCANY-1312:
------------------------------
I think this error you got, is something correct in Tuscany.
In fact to implement an component with java, use <implementation.java
class="[class name]"/> will work find, although the osoa's spec has mentioned
<interface.java interface="[class name]"/>. In Tuscany, the second way will
work find with a <binding.ws> followed.
I think this is enought and logical.
Use <interface.java interface="[class name]"/> just mess things.
> Can not expose Java Implementation class as a service
