Constant Field Values

ERROR

public static final int ERROR

Logging level for messages that explain why the desired operation cannot be performed.

Note: A simple way for deriving goog error messages is to make them fit the pattern:

cannot do something: actual state must match expectation.

Just fill in "do something", "actual state" and "expectation".

In case your code is just reporting a Java Exception that happens at a lower level on the call stack, use the pattern:

cannot do something: < exception.getMessage() >.

In practice, the latter often results in sucky error messages, but there is not much you can do about it apart from making sure that your own Exceptions have a useful getMessage().

INFO

public static final int INFO

Logging level for messages that tell details about normal operations currently going on.

Constant Field Values

WARN

public static final int WARN

Logging level for messages that notify about things that can be processed, but the user might want to take a closer look at the current situation.

Note: Warnings are a good indicator for bad design. They hint at the developer being to dumb to resolve a situation and therefor delegating the responsibility to the user. Preferrably, the code shoud be changed to either log INFO, throw an exception or log ERROR.
