I have a JUnit test that starts a Jetty server for serving a hello
world
resource (source of test included below).
When I add the OAuth (1.6) server jar file to the classpath for this
test case
without using OAuth anywhere the server reports the following
exceptions:
SEVERE: The provider class, class
com.sun.jersey.oauth.server.OAuthProviderInjectionProvider, \
could not be instantiated. Processing will continue but the class will
not be utilized
java.lang.RuntimeException: No OAuthProvider implementation found in
the list of providers.
at
com.sun.jersey.oauth.server.OAuthProviderInjectionProvider.<init>(OAuth
ProviderInjectionProvider.java:71)
at
sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)
[Full server output below.]
The exception seems harmless. I can extend the test case to use OAuth
in the
client and the server OK. But naturally it bugs us to see the exception
on each
test run. And I have not been able to figure out how to avoid it.
Do I need further configuration and setup of the jersey servlet
container to
avoid this?
Many thanks.

The test case:
public class TrialTest extends TestCase
{
public void testStartServer() throws Exception
{
Server instance = new Server(8181);
ServletContextHandler context = new
ServletContextHandler(ServletContextHandler.SESSIONS);
context.setContextPath("/services");
instance.setHandler(context);
Servlet servlet = new
com.sun.jersey.spi.container.servlet.ServletContainer();
ServletHolder servletHolder = new ServletHolder(servlet);
Map<String, String> initParameters = new HashMap<String,
String>();
initParameters.put("com.sun.jersey.config.property.packages",
HelloWorldResource.class.getPackage().getName());
servletHolder.setInitParameters(initParameters);
context.addServlet(servletHolder, "/rest/*");
instance.start();
}
}
The server output:
