I tried to use the information at
http://www.eclipse.org/jetty/documentation/current/using-annotations-embedded.html
but on startup I get a bunch of exceptions during annotation processing.

Examining the transitive dependencies I found
asm-all-repackaged-2.2.0-b21.jar
asm-4.1.jar
asm-commons-4.1.jar
asm-tree-4.1.jar
with asm-all-repackaged-2.2.0-b21 coming from jersey-container-jetty-servlet.
Examining the sources I find that indeed, org.objectweb.asm.ClassVisitor
changed from an interface in 2.2.0 to an abstract class in 4.1.
However, I still get the error even after removing
asm-all-repackaged-2.2.0-b21.jar from the jetty classpath.
Here's the Java embedded launcher code:
import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.webapp.Configuration.ClassList;
import org.eclipse.jetty.webapp.WebAppContext;
public class JettyLauncher
{
public static void main(String[] args) throws Exception
{
Server server = new Server(8080);
ClassList classlist = ClassList.setServerDefault(server);
classlist.addAfter("org.eclipse.jetty.webapp.FragmentConfiguration",
"org.eclipse.jetty.plus.webapp.EnvConfiguration",
"org.eclipse.jetty.plus.webapp.PlusConfiguration");
classlist.addBefore("org.eclipse.jetty.webapp.JettyWebXmlConfiguration",
"org.eclipse.jetty.annotations.AnnotationConfiguration");
WebAppContext wac = new
WebAppContext("target/server-0.1.0-SNAPSHOT","/test");
server.setHandler(wac);
server.start();
server.join();
}
}
Questions:
1) Why didn't removing asm-all-repackaged from the classpath make it work?
2) Is it possible to get Jetty and Jersey to play nice when using annotations?
