I went to look at the source code and found something I'd completely
forgotten about. Tomcat exposes several properties that you can use in
logging.properties. They are:
classloader.webappName
classloader.hostName
classloader.serviceName
There are several ways you could make use of those.

Thank you, Mark!
Excuse me, I forgot describe deployment. Formatter implemented as
library (log-formatter.jar). I specified classpath to this library in
setenv.sh:
echo "Setting parameters from $CATALINA_BASE/bin/setenv.sh"
echo "_______________________________________________"
export CLASSPATH="$CATALINA_BASE/lib/log-formatter-1.0.jar:$CLASSPATH"
echo "_______________________________________________"
echo ""
Logging configured globally in ${catalina.base}/conf/logging.properties
file:
...
org.apache.tomee.jul.formatter.AsyncConsoleHandler.level = FINE
org.apache.tomee.jul.formatter.AsyncConsoleHandler.formatter =
my.log.formatter.OneLineFormatter
org.apache.tomee.jul.formatter.AsyncConsoleHandler.encoding = UTF-8
...
Looks like, I cannot access to ServletContext directly... Maybe there
any other way, to get servlet context from InitialContext or application
name from LogManager property:
java.util.logging.LogManager.getLogManager().getProperty(...)
Do you know desired property or how to list LogManager properties?

Use ServletContext.getContextPath()?
If you have a more complex deployment you might want to preface it
with ServletContext.getVirtualServerName()

Hello! I want to print application name in my log files. As I know, I
must implemet custom log formatter. How I can get application name?
import java.util.logging.Formatter;
import java.util.logging.LogRecord;
public class MyCustomLogFormatter extends Formatter {
@Override
public String format(LogRecord record) {
String webappName = ...;
return String.format("%s/n", webappName); // only application
name for testing
}
}
I use Tomcat 9.0.
