How to migrate from embedded jetty 10 to jetty 12 ee8?

Question content

I try to port from jetty 10.x to jetty 12.x ee8. After I changed the dependencies according to this list https://download.eclipse.org/tools/orbit/simrel/maven-jetty/release/12.0.6/. I'm getting some compiler errors while using embedded jetty.

There seems to be no ee8 server class, I use org.eclipse.jetty.server.server. This class extends from org.eclipse.jetty.server.handler.wrapper.

But the handler for jetty-ee8-nested extends from org.eclipse.jetty.ee8.nested.handlerwrapper, which is incompatible. For example org.eclipse.jetty.ee8.nested.inetaccesshandler. One expects org.eclipse.jetty.server.handler and the other org.eclipse.jetty.ee8.nested.handler

Is there another implementer of the server I oversee? Where can I find it? What about class names?

Or do I have to modify my code? For example, how do I change the following line?

InetAccessHandler ipaccess = new InetAccessHandler();
ipaccess.setHandler( getHandler() );
setHandler( ipaccess );

Correct answer

First, there is a migration guide from jetty 11 to jetty 12: https:// eclipse.dev/jetty/documentation/jetty-12/programming-guide/index.html#pg-migration-11-to-12

It shows many of the things you asked about.

Ignore Classes in the org.eclipse.jetty.ee8.nested.* package, these are internal classes of the ee8 layer.

Use org.eclipse.jetty.server.handler.inetaccesshandler.

You can wrap it around any handler, for example: org.eclipse.jetty.server.handler.sequence, org.eclipse.jetty.ee8.webappwebappcontext, etc. ...

InetAccessHandler inetAccessHandler = new InetAccessHandler();
// allow only http clients from localhost IPv4 or IPv6
inetAccessHandler.include("127.0.0.1", "::1");
server.setHandler(inetAccessHandler);

Handler.Sequence handlers = new Handler.Sequence();
inetAccessHandler.setHandler(handlers);

WebAppContext webapp = new WebAppContext();
webapp.setContextPath("/");
webapp.setWar(warPath.toUri().toASCIIString());

handlers.addHandler(webapp);

This snippet comes from https:// /github.com/jetty/jetty-examples/tree/12.0.x/embedded/ee8-webapp-context
