Alex,
You're running the code under OSGi?
To me, this looks like the binding-rest-runtime module has not been tested running under OSGi. It
is clearly missing one MAINFEST.MF entry, which causes the ClassNotFound exception you're getting.
I am concerned that there may be more similar failures due to the lack of testing under OSGi.
To fix the particular problem you have here, the following needs to be added to the Import-Package:
section of the MANIFEST.MF for the binding-rest-runtime module:
org.apache.tuscany.sca.interfacedef.java;version=2.0.0,
However, just adding this may well not be enough.
I am not familiar with the binding-rest-runtime module, so it will take me some time to get to grips
with it and make it work properly under OSGi - hopefully someone else from the Tuscany team can take
a look at it more quickly.
Yours, Mike.

Hi,
I have a problem to export a REST service via an OSGi bundle. Most of
the code is taken from the store example for binding.rest.
