You have to configure 2 different "appenders": a ConsoleAppender and a FileAppender, then you can direct output to one of them or both. To select which appender will receive a log item you can discriminate on logging priority (for example console could receive only ERROR and FATAL items, the log file could receive everything) and/or the class or package producing that log item. The log4j intro documentation page explains how to make this configuration.
