RESTEasy logs various events using slf4j.
The slf4j API is intended to serve as a simple facade for various logging APIs allowing to plug in the desired implementation at deployment time. By default, RESTEasy is configured to use Apache log4j, but you may opt to choose any logging provider supported by slf4j.
The logging categories are still a work in progress, but the initial set should make it easier to trouleshoot issues. Currently, the framework has defined the following log categories:
Logs all activity by the core RESTEasy implementation
Logs all activity by RESTEasy entity providers
Logs all activity by the RESTEasy server implementation.
Logs all activity by JAX-RS implementing classes
Logs all activity by the RESTEasy mock framework
If you're developing RESTEasy code, the LoggerCategories class provide easy access to category names and provides easy access to the various loggers.
