java.util.logging

问题 I am seeing a problem with an Applet on Windows, running Java 9, when I am trying to create a log file C:\Users\cardal\ApplicationLog.html. The code works fine on Java 8. The code does LogManager.readConfiguration () and LogManager.getLogger(). Then Logger.getHandlers() hits an exception. It looks like the first slash is getting removed by mistake: Can't load log handler "java.util.logging.FileHandler" java.nio.file.NoSuchFileException: C:Users\cardal\ApplicationLog.html.lck java.nio.file

问题 We have started using a third party platform (GigaSpaces) that helps us with distributed computing. One of the major problems we are trying to solve now is how to manage our log files in this distributed environment. We have the following setup currently. Our platform is distributed over 8 machines. On each machine we have 12-15 processes that log to separate log files using java.util.logging. On top of this platform we have our own applications that use log4j and log to separate files. We

问题 I have java.util.logging to print output to a file. It works fine. However, the messages contain chinese characters which correspond to the log level and the time the messages are logged. How can I make it print english instead of chinese characters ?

问题 I saw Java Logging - where is my log file?, but in my case I would like to find out in my Java application which logfile the FileHandler actually opened, i.e. if I start multiple processes and have a pattern set as java.util.logging.FileHandler.pattern=MyApp.%g.%u.log Then the %g and %u will be replaced with numbers depending on how many processes are running. I can iterate over all logging Handlers and find the File-based one. But as far as I see there is no method in FileHandler to get the

问题 I have a logging.properties file in my Java AppEngine project (using java.util.logging ) that looks like this: # Set the default logging level for all loggers to WARNING .level = INFO # tighten logging on the DataNucleus Categories DataNucleus.JDO.level=WARN # - All messages general to JDO DataNucleus.JPA.level=WARN # - All messages general to JPA DataNucleus.Persistence.level=WARN # - All messages relating to the persistence process DataNucleus.Query.level=WARN # - All messages relating to

问题 I want to create Handler that will be catch all Logs of web aplications on Tomcat, I Created my Handler class, compiled it and put on $CATALINA_HOME/lib , and common.loader has this directory. After this I modified the logging.properties file and added the handler: handlers = 1catalina.org.apache.juli.FileHandler, 2localhost.org.apache.juli.FileHandler, 3manager.org.apache.juli.FileHandler, 4host-manager.org.apache.juli.FileHandler, java.util.logging.ConsoleHandler, logshowaplication

问题 I'm trying to load a custom log.properties file when my application is started. My properties file is in the same package as my main class, so I assumed that the -Djava.util.logging.config.file=log.properties command line parameter should get the properties file loaded. But the properties are only loaded when i specify a full absolute path to the properties file. Any suggestions how to use a relative path? 回答1: Java logging doesn't search your whole hard disk for a file; there are very simple
