We maintain an example project of getting Embedded Jetty and JSP working together at https://github.com/jetty-project/embedded-jetty-jsp
There's Jetty 9, Jetty 10, and Jetty 11 versions (see the branches with the appropriate names). Then there's also the general cookbook for Embedded Jetty that might help you with specific topics as well. https://github.com/jetty-project/embedded-jetty-cookbook As for your specific concerns, you are likely not initializing the JSP layer properly (see first link above to jsp examples), and/or are still using older Configuration (class/object) techniques (see second link above to cookbook examples).
