FusionReactor Technote - FRS-222

Symptoms

When FusionReactor is installed on the Caucho Resin 3.x application server with virtual hosts configured (called 'webs' by Railo) the request, jdbc and crashprotection log messages are processed by Resin only but no written to the associated FusionReactor log file.

Analysis

The issue occurs because of the way the Resin 3.1 application server manages the log handler objects used by FusionReactor. Analysis of this problem showed that these handlers could not be retrieved correctly in an environment using multiple Resin EnvironmentClassloader instances which resulted in log messages being written to the default log configured in Resin only.

Note

If you see FusionReactor messages written to STDOUT (or into a Resin log file) you may need to restrict the log configuration of the Resin server accordingly. The following definition in the resin.conf file

<!--- Logging configuration for the JDK logging API. -->
<log name='' level='all' path='stdout:' timestamp='[%H:%M:%S.%s] {%{thread}} '/>

should be changed to something like

<!--- Logging configuration for the JDK logging API. -->
<log name='com.caucho' level='all' path='stdout:' timestamp='[%H:%M:%S.%s] {%{thread}} '/>

so that the FusionReactor loggers are excluded.
