Re: [jetty-users] Migration help to Jersey 3 / Jetty 11

[chris@xxxxxxxxxxxxxxxx]

SSCCE: https://github.com/chriswhocodes/ModernREST

On trying to access the HttpServletRequest injected by:

	@Context private HttpServletRequest servletRequest;

I get an NPE:

	HttpSession session = servletRequest.getSession(true);

I'm trying to create a modern JakartaEE / Jersey 3 / Jetty 11 webapp 
with all configuration in code, no XML wiring, like I did here:

https://github.com/chriswhocodes/JaCoLine/blob/master/src/main/java/com/chrisnewland/jacoline/web/WebServer.java
https://github.com/chriswhocodes/JaCoLine/blob/master/pom.xml

Thanks,

Chris
