This adapter sends log output to SLF4J. SLF4J supports multiple implementations such as Logback, Log4j, Jakarta Commons Logging (JCL), JDK 1.4 logging, x4juli, and Simple Log. To use SLF4J, you need to add the required jar files to the classpath, and set the trace level to 4 when opening a database:

 jdbc:h2:˜/test;TRACE_LEVEL_FILE=4
 

The logger name is 'h2database'.
