Can't deploy jooby project on Jetty/Tomcat

[dynnoil]

I have a problem with deploying assembled war archieve with Getting Started project to Jetty server. When I try to refer to app url, I get 503 Service Unavailable.
I'm using Jetty 9.4.2.v20170220.

War archieve contains following libs:

• slf4j-api-1.7.21.jar
• logback-classic-1.1.7.jar
• logback-core-1.1.7.jar
• http2-server-9.4.0.v20161208.jar
• http2-common-9.4.0.v20161208.jar
• http2-hpack-9.4.0.v20161208.jar
• afisha-1.0-SNAPSHOT.jar
• jooby-servlet-1.0.3.jar

Thanks.
