XML<property name="eclipselink.logging.level" value="WARNING" />Change the value to one of the following (listed in order from the least amount of log information to the most):
- OFF
 - SEVERE
 - WARNING

 - CONFIG
 - FINE
 - FINER
 - FINEST
 - ALL
 
For example:
XML<property name="eclipselink.logging.level" value="SEVERE" />- Save your changes.
