Re: [jetty-user] NullPointerException at XmlConfiguration$1.run(XmlConfiguration.java:1138) in jetty-8.0.4.v20111024

Justin,

If you're not trying to start jetty in an embedded mode, use "java
-jar start.jar". jetty will take care of setting up classpaths and
classloaders for itself and for any webapps. To use jetty in this
fashion, do not set up anything on your classpath. Just have the jdk
on the system classpath.

If you are trying to start jetty in an embedded fashion, then the best
way to do that is to write yourself a main class, following the
tutorials here:

cheers
