There are several parameters that are used by OpenJPA Log. Here are some that might be of value when debugging test cases:. Note that the logger names are case sensitive while the log levels are not.

• DefaultLevel sets the level for all loggers that are not otherwise set
• file sets the file name for logging output
• Enhance logs messages from the enhancer
• Metadata logs messages from the metadata processor
• Tool logs messages from the schema synchronization tool
• SQL logs messages from the SQL generator
• JDBC logs messages related to JDBC
• Schema logs messages related to schema
• Runtime logs messages related to runtime
• Query logs messages related to queried
• DataCache logs messages related to caching

Log levels are:specify the minimum log message that is output. All log messages with a level higher than the log level set for a logger are output. So if INFO is specified, log messages of level INFO, WARN, ERROR, and SEVERE are output.

• TRACE
• INFO
• INFO
• TRACE
• WARN
• ERROR
• SEVERE

For example, to avoid enhancement warnings, get detailed SQL information, and write the log data to a file:

mvn test -Dtest=TestPersistence -Dopenjpa.Log=Enhance=ERROR,SQL=TRACE,file=openjpa.log
