Re: [jetty-users] java.lang.NoClassDefFoundError: org/eclipse/jetty/util/Attributes$Wrapper
Found the problem! Just in case anyone encountered the same problem.

The issue was that the the jerser-server (v2.31) had a dependancy on jetty-server (v9.4.27), and we were configured with jetty-server (v9.4.31).

Thank you all for your help.

It worked at some point and then suddenly when I structured the folder holing the webapp I just started getting these errors. I am running jetty embedded, and launch both an angular web application (ContextHandler), and also a servlet (createServletContextHandler), and using adding them to a ContextHandlerCollection.

Hello

 

I use Jetty with Jersey, I have no such problems, you can have a look at my project, maybe it could help you:

https://sourceforge.net/projects/red-feed-aggregator/

 

I think that a dependency is missing in your pom file.

Hello,
 
I am new to Jetty and have seen some inconsistent behavior that I am struggling to find the cause. I am using the embedded jetty via a maven dependency file that is shown below. I am trying to use the the jersey container to support webservice annotations.
