Theo chỉ định của PeskyGnat trong câu trả lời này bạn phải tạo tệp logging.properties trong thư mục:
Sau khi định cấu hình tệp này, bạn có thể xem nhật ký:
Trong trường hợp của tôi, đây là Solaris nên con đường đầu tiên là:
Và cái thứ hai:
Như thông tin bổ sung, để dễ dàng tìm thấy tệp nhật ký, bạn có thể nhập vào Bash shell như sau:
ls -altr
Và đây là ví dụ về cách tệp logging.properties:

# Default Logging Configuration File

# You can use a different file by specifying a filename

# For example java -Djava.util.logging.config.file=myfile

# "handlers" specifies a comma separated list of log Handler
# classes. These handlers will be installed during VM startup.
# Note that these classes must be on the system classpath.
# By default we only configure a ConsoleHandler, which will only
# show messages at the INFO and above levels.
handlers= java.util.logging.ConsoleHandler
# To also add the FileHandler, use the following line instead.
#handlers= java.util.logging.FileHandler, java.util.logging.ConsoleHandler
# Default global logging level.
# This specifies which kinds of events are logged across
# all loggers. For any given facility this global level
# can be overriden by a facility specific level
# Note that the ConsoleHandler also has a separate level
# setting to limit messages printed to the console.
.level= INFO

java.util.logging.FileHandler.pattern = %h/java%u.log
java.util.logging.FileHandler.limit = 50000
java.util.logging.FileHandler.count = 1
java.util.logging.FileHandler.formatter = java.util.logging.XMLFormatter
# Limit the message that are printed on the console to INFO and above.
java.util.logging.ConsoleHandler.level = INFO
java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter

# For example, set the com.xyz.foo logger to only log SEVERE
# messages:
**<your.class.logger>.level = <level> (i.e.: INFO)**
