Using the shipped implementation
The Logback logging implementation is shipped in the
logging folder in the client distribution. To use this framework, simply add
logback-classic and the
logging folder itself to your Java classpath at runtime. This is detailed in
The configuration can be modified in
logging/logback.xml. See the Configuration documentation for more information.
Integrating with existing logging
If your code already contains an SLF4J implementation, it will be picked up and used automatically by the Open Access code.
Troubleshooting no logging
If you are seeing no logging from the API, check the initial output when you first run your program. If you see something similar to below:
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". SLF4J: Defaulting to no-operation (NOP) logger implementation SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
verify that a logging implementation is on your classpath as per above.
