I guess this is still the trunk version from last week.
Logging has been updated in the XSLT component since then.
For every processed exchange, the following elements are logged at the INFO level:
+ An exchange was received.
+ The request was validated, the transformation is about to start.
+ The exchange was successfully processed.
+ The exchange processing encountered a problem.
Each log entry for these elements (as well as for all of the JBI listener) starts with the exchange ID.
Logging rules for components are defined on this page: http://doc.petalslink.com/display/petalsesb/Advanced+topics+and+guidelines
The logs at INFO level must be audit logs.
It means that they must indicate what event happends in the bus.
This trace is relevant at INFO level, but must contains the ExchangeID and the correlationID if defined.
If you do not want that kind of trace, change the log trace level at warning in the component.
