Re: [jetty-users] Migrating from jetty-9.2.11.v20150529-all.jar to jetty-9.3.2.v20150730-uber.jar results in a HTTP Error 404

Ok, did a little more trial and error and found that if I don’t add the session handler to the context things work as expected. 

 

The problem is I would like to use an event listener to keep track of sessions and would like to continue to doing so.  Note: I also tested just adding the session without an event listener and had the same result.

 

Did something change with the behavior of the Session Manager / handler?

 

Any thoughts/ideas?

There's no servlets or filters on your main ServletContextHandler.

No AppServlet, no SessionFilter, nothing.

There's not even a DefaultServlet or Default404Servlet.

There's no resource base either (its null).

That ServletContextHandler has nothing to serve, not even static content, not even a 404 error.

 

However, there is a strange com.host.reporter.ServletContainer$1@5069a91b present in your HashSessionManager.

Can you do a System.out.println(server.dump()) after the setup of the server? If you see a ServletHandler$Default404Servlet in the dump, you might have the same effect I had when I started the thread with MID <55155AAD.6040309@xxxxxxxxxxxxxx>.

I helped myself with manually removing that servlet from the handler (which wasn't fun but does at least work). Maybe Jetty 9.3 gives you a way to tell the server to not add the 404-servlet automatically (which isn't possible with 9.2), so you might be able to get around the (really ugly) hack.


Cheers, Lothar
