endpoints not showing in glassfish 3.1.2

Hello,

We are having deployment issues when going from version 3.0.1 to 3.1.2.
In 3.0.1 we have created a sun-jaxws.xml deployment descriptor and the war deployes correctly to glassfish and you can view its endpoints and wsdl and tester.
When we deploy the same war file to glassfish 3.1.2 it says that it has successfully deployed in the admin console but when clicking on the webservice there is no endpoints and I cannot manually go to the generated wsdl file.

<?xml version="1.0" encoding="UTF-8"?>

interface="com.etc....CommonInquiryWS"
implementation="com.....impl.CommonInquiryWSImpl"
url-pattern="/commonInquiryWService" />

There is no errors in the logs, the only difference is that 3.0.1 displays:
INFO: WS00018: Webservice Endpoint deployed
CommonInquiryWSImpl listening at address at http://localhost:8080/...

and 3.1.2 does not.

Has anyone come across this problem? Or know why the descriptor for 3.0.1 does not work for 3.1.2? Am i missing metadata? Do I need to make any changes to the sun-jaxws.xml file?

Thanks
