log4j category

First, your category is not mapped to an appender, second ConsultaDadosEORI doesn't match any category.

Here is a sample :

log4j.appender.YOUR_APPENDER=org.apache.log4j.RollingFileAppender
log4j.appender.YOUR_APPENDER.File=${SYSTEM_PROPEY_WITH_LOGGER_FOLDER}/log_file.log
log4j.appender.YOUR_APPENDER.Append=true
log4j.appender.YOUR_APPENDER.MaxFileSize=20MB
log4j.appender.YOUR_APPENDER.MaxBackupIndex=2
log4j.appender.YOUR_APPENDER.layout=org.apache.log4j.PatternLayout
log4j.appender.YOUR_APPENDER.layout.ConversionPattern=%d [%t] %p %c - %m %n
log4j.category.**YOUR_PACKAGE**=**INFO,YOUR_APPENDER** 
log4j.additivity.**YOUR_PACKAGE**=true or false

Just to finish this thread, the real issue was that the first value on your category line should have been a log level. So, as you correctly discovered, changing :

log4j.category.ConsultaDados=ConsultaDados

to

log4j.category.ConsultaDados=info,ConsultaDados

worked properly. As an FYI, you could have also changed the line to

log4j.category.ConsultaDados=,ConsultaDados

which would have caused you to inherit the logging level from the root logger.
