问题
I'm trying to get websockets working with jetty. I'm on eclipse. When I try to run it, following error appears on console. java.lang.NoClassDefFoundError: org/objectweb/asm/ClassVisitor
I even tried with test.war that is provided with jetty. But error remains same.

Are you using the Jetty WTP Eclipse plugin to run the server? If so, then try this: http://pipecuts.wordpress.com/2011/01/30/classnotfoundexception-org-objectweb-asm-classvisitor/
It worked for me.
