Hi Everyone,
It can be annoying that Knox doesn't always log stacktraces for
exceptions by default. To get stack traces into the log you probably
need to change the logging level to someting finer like DEBUG. The
log4j.properties file in a Knox install (i.e.
{GATEWAY_HOME}/conf/log4j.properties) already has a logger configuration
that you can enabled. If you change this don't forget to restart the
server.
I also say "probably" above because it depends on how your log messages
are defined. Take a look at this example from GatewayMessages.
@Message( level = MessageLevel.FATAL, text = "Failed to start
gateway: {0}" )
void failedToStartGateway( @StackTrace( level = MessageLevel.DEBUG )
Exception e );
The @StackTrace( level = MessageLevel.DEBUG ) tells the logging
framework to only log the stack trace if the debug level is DEBUG or
finer. This level could be set to anything equal to or finer than the
message level itself. In practice the @StackTrace level appears to be
typically set to DEBUG.
Hope this helps someone.
Kevin.
