jetty

Jetty provides a Web server and javax.servlet container, plus support for HTTP/2, WebSocket and many other integrations.

exports

Jetty Server

dependency

<dependency>
  <groupId>org.jooby</groupId>
  <artifactId>jooby-jetty</artifactId>
  <version>1.6.6</version>
</dependency>

usage

In order to use a web server all you have to do is add the dependency to your build system. Jooby will find the server and start it.

http/2

HTTP/2 is fully supported:

| H2        | H2C           | PUSH  |
| --------- | ------------- | ----- |
| Yes       | Yes           | Yes   |

You need to add alpn-boot to the JVM bootstrap path. See Jetty HTTP2 documentation.

      # call, although with NIO implementations other mechanisms may be used to implement the timeout. 
      # The max idle time is applied: 
      # When waiting for a new message to be received on a connection 
      # When waiting for a new message to be sent on a connection

    }
