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

I have created a starter template project to start Jakarta EE 9 servlet web application, but I used an external Jetty to serve the application in this project,

It would be useful if you could provide either a pointer to your project or a minimum reproducible example. The exact stacktrace you get would also be useful.

Hi,

I'm having trouble migrating a Jersey/Jetty project (2.25) to Jersey 3 /
Jetty 11.

The Jersey part is working fine and I can serve requests using
jersey-container-simple-http with a ResourceConfig to specify the
service and filter classes.

When I try to use a Jetty 11 jersey-container-jetty-http container to
add static resources and HttpServletRequest session handling I'm unable
to work out the correct steps to convert the code below to use the
latest APIs.

The HttpServletRequest injected by @Context is always null and I think
I'm hitting the same problem as this post:

My pom dependencies are:

    <jersey.version>3.0.3</jersey.version>

     <dependencyManagement>
         <dependencies>
             <dependency>
                 <groupId>org.glassfish.jersey</groupId>
                 <artifactId>jersey-bom</artifactId>

             <groupId>org.glassfish.jersey.media</groupId>
             <artifactId>jersey-media-json-jackson</artifactId>

And advice would be greatly appreciated please.

Many thanks,
