Hi Quintes,

remove jetty-maven-plugin from your dependencies (it’s a build plugin and
it’s causing you the issues). Plus make sure you’re not using Jersey 1.x
properties (prefix com.sun.jersey):

        Server server = new Server(8081);
        ServletContextHandler context = new
ServletContextHandler(ServletContextHandler.NO_SESSIONS);
        context.setContextPath("/");
        server.setHandler(context);

        ServletHolder servletHolder =
context.addServlet(org.glassfish.jersey.servlet.ServletContainer.class,
"/api/*");

servletHolder.setInitParameter("jersey.config.server.provider.packages",
"quintes.rest");

        try {
            server.start();
            server.join();
        } catch (Throwable t) {
            t.printStackTrace(System.err);
        }

your resource would be available at http://localhost:8081/api/test

running jersey 2.5.1 and embedding jetty jetty-9.1.2.v20140210

I want an embedded jetty server capable of servlet 3x as well as jersey. I
know that my jetty instance works as servlet handler and static file
hander. however the following details I get this error:
java.lang.IncompatibleClassChangeError: Implementing class

I am sure it is related to cglib / asm but not sure how to fix it.

Here's the project :

the rest app class like this:
@ApplicationPath("/")
public class Application extends ResourceConfig {

public Application() {
packages("quintes.rest");
}

}

the REST resource:
@Path("test")
public class restresource {

@GET
@Produces({MediaType.APPLICATION_JSON})
public Response getDefault() {
return Response.ok("test returned").build();
}

}

and the main() like this:
public class App {

public static void main(String[] args) {

Server server = new Server(8081);
ServletContextHandler context = new
ServletContextHandler(ServletContextHandler.NO_SESSIONS);
context.setContextPath("/");
server.setHandler(context);

ServletHolder servletHolder =
context.addServlet(org.glassfish.jersey.servlet.ServletContainer.class,

servletHolder.setInitParameter("com.sun.jersey.config.property.resourceConfigClass",
"com.sun.jersey.api.core.PackagesResourceConfig");

servletHolder.setInitParameter("com.sun.jersey.config.property.packages",
"quintes.rest");

ServletHolder staticServlet = context.addServlet(DefaultServlet.class,
"/*");
staticServlet.setInitParameter("resourceBase", "src/main/webapp");
staticServlet.setInitParameter("pathInfoOnly", "true");

try {
server.start();
server.join();
} catch (Throwable t) {
t.printStackTrace(System.err);
}
}
}

however I get the error mentioned as part of this stack trace:
