It is possible that you are decorating the wrong location/classes for your coverage. Try a server dump, it will show you what classes jetty is using. (it might not be what you assume) To set this up with the jetty-maven-plugin Create a jetty-dump.xml (or whatever name you want) <?xml version="1.0"?> <!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" " http://www.eclipse.org/jetty/configure_9_0.dtd";> <Configure id="Server" class="org.eclipse.jetty.server.Server"> <Set name="dumpAfterStart">true</Set> </Configure> Then configure the plugin to use it ... <plugin> <groupId>org.eclipse.jetty</groupId> <artifactId>jetty-maven-plugin</artifactId> <configuration> <jettyXml>jetty-dump.xml</jettyXml> </configuration> </plugin> The STDERR / STDOUT should have a lot of extra information in it now. -- Joakim Erdfelt <[email protected]> webtide.com <http://www.webtide.com/> - intalio.com/jetty Expert advice, services and support from from the Jetty & CometD experts eclipse.org/jetty - cometd.org
