Hello Ci-Ci,
you probably don't have any provider in your project so not finding one
is not an issue.
I just recreated your app (modified jersey helloworld sample) and it is
working for me;
GET
http://localhost:9998/auth/username/authenticate
returns
<?xml version="1.0" encoding="UTF-8" standalone="yes"?><User><username>sam</username><status>active</status></User>
(I fixed some typos but I presume that is not the cause of your
problem). Can you share your project or minimal failing testcase (better
alternative)?
