Use of ServiceDiscovery in JavaImplementationProvider.loadPolicyHanlders
Hi,
With the recent 'classloader' changes the enhancements that I'd did in the
the calculator sample to demonstrate the use of implementation policies does
not seem to work anymore. Its primarily to do with the loading of
PolicyHandler class names from
META-INF/services/org.apache.tuscany.sca.policy.PolicySetHandlers file in
the implementation-java-runtime module. Earlier I used to load this file
from the JavaImplementationProvider.loadPolicyHandlers using the TCCL.
After the classloader related clean up the 'loadPolicyHandler' method now
uses ServiceDiscovery.getServiceResources and I see that the file doesn't
seem to get loaded. Can somebody point to that which I am missing here ?
Thanks.

Hey, not at all. Its actually my bad. It would not have happened if I had
used a constant there instead of the string literal :). That's fixed now.

Venkat,
Sorry about that. The service filename had changed between the time I
started implementing the classloader changes and submitted the patch. I
should have been more careful when merging the changes.
Thank you...

Rajini

Ok, I figured this out. There's been a change in the name of the services
file that used to contain the Policy hanlders.
Thanks
