Missing 'file' Appender Configuration in Log4j Properties.

[Dimos N.]

Description

The log4j.rootLogger references the 'file' appender but the appender is not defined in the configuration file.

# Root logger
log4j.rootLogger=INFO, file, stdout

# Write to console
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

Expected Behavior:

The Log4j properties file should either include a properly configured 'file' appender to allow logging to a file as indicated by the log4j.rootLogger configuration or the 'file' appender should be removed.

Current Output:

log4j:ERROR Could not find value for key log4j.appender.file
log4j:ERROR Could not instantiate appender named "file".
