Copying jetty-client-7.3.0.v20110203.jar to WEB-INF/lib (Jetty IRC suggestion) doesn't resolve the issue -- same error.

The Jetty test webapp has this servlet OK, so it is probably best to model your webapp on that.

You need to make sure that all the dependent jars are available:

[INFO] org.eclipse.jetty:jetty-client:jar:7.4.1-SNAPSHOT
[INFO] +- org.eclipse.jetty:jetty-http:jar:7.4.1-SNAPSHOT:compile
[INFO] |  \- org.eclipse.jetty:jetty-io:jar:7.4.1-SNAPSHOT:compile
[INFO] |     \- org.eclipse.jetty:jetty-util:jar:7.4.1-SNAPSHOT:compile


you can put these in WEB-INF/lib
or you can add client to the start.ini OPTIONS and update the contexts classloader configuration so those classes are visible.


Either way, closing this as it is not a bug - rather a request for support. So please follow up on jetty mailing lists.
