Embedding Apache TomcatΒΆ

You can make Armeria serve your JEE web application on the same JVM and TCP/IP port by adding a TomcatService to a Server:

import com.linecorp.armeria.server.ServerBuilder;
import com.linecorp.armeria.server.http.tomcat.TomcatService;

ServerBuilder sb = new ServerBuilder();


Note that Tomcat will not open a server socket or accept an incoming connection. All HTTP requests and responses go through Armeria. As a result, you get the following bonuses:

  • Your webapp gets HTTP/2 support for free even if Tomcat does not support it.
  • You can run your RPC services on the same JVM and port as your webapp with no performance loss.

For more information, please refer to the API documentation of TomcatService and TomcatServiceBuilder.
