For development I use Jetty locally via jetty-maven-plugin. One of the nice features it has WebSocket support so there is no need to use standalone application servers like Wildfly.
If you check jetty documentation you'll see that request logging is configured in jetty's context xml file. Fortunately if you don't want to add another xml to your project there is another option.
Add the following configuration to your project's pom.xml:
The implementation attribute value of the requestLog property can be one of these: AsyncNCSARequestLog, NCSARequestLog or Slf4jRequestLog. Note that options vary depending on the implementation. I choose NCSARequestLog because it produces logs in NCSA common log format
The log file will be created in the root directory of your project when jetty is started.
