This took me quite a while and lots of runtime errors, here are the minimum jars I needed to add to my project since now cling when used on android needs jetty, and damn jetty is broken into a thousand little jars for maximum modularity.
These are the one jars that I needed to not have any more runtime (class not found) errors
jetty-security-8.1.8.v20121106.jar
jetty-http-8.1.8.v20121106.jar
jetty-continuation-8.1.8.v20121106.jar
jetty-io-8.1.8.v20121106.jar
