Java logging can be configured by placing a logging configuration file named ddlog.properties in the Server DB directory (see "Configuring server mode" for information on configuring Server DB Directory). The simple way to create one of these is to make a copy of the ddlog.properties file, which is located in your driver installation directory, in the install_dir/Sample/Example subdirectory.

For more information, refer to Logging for Java components in the Progress DataDirect for ODBC Drivers Reference.
