java.util.logging

I have a Java 10 application on Windows Server 2016 which is continually writing to a file using java.util.logging. In Windows File Explorer, the "Last modified" and "Size" columns do not update. Pressing [F5] does not update the details. DOS DIR gives the same incorrect answer. Right Click > Properties > Details gives an even different (and older) answer. Only running DOS TYPE or opening/closing (without save) in Notepad on the file, seems to cause File Explorer and DOS DIR to update. I assume the Java code is correct with respect to flush() as the same classes on Java 8 on Windows Server

I would like to log in my application which consist of several classes. I would like to have one .txt log file at the end. Therefore I make one static logger instance and I made a FileHandler for it in one class. Because I would like to have one file, I set the second argument for true in the FileHandler to be able to append the log file during logging. public class MyLogging { static Logger logger; public Handler fileHandler; Formatter plainText; public MyLogging() throws IOException{ //instance the logger logger = Logger.getLogger(MyLogging.class.getName()); //instance the filehandler

I'm looking into hooking up a 3rd party Java application to our log aggregation/analysis solution (probably Splunk, we haven't finalized our selection yet though). It seems to be easiest to hook the Splunk agent to syslog, so I'm looking for a way to redirect the application logs to a local syslog daemon on the server. The Java application uses java.util.logging, which unfortunately does not feature a syslog handler out of the box (I believe log4j does, though). Are there any proven libraries to do this? The log load isn't huge (probably 10-20 messages per minute from each process, up to 6

I want to logging to file and set it in properties file, because default logger.info() output goes to console and in web application there is no console in my case. Victor As Navi says... it goes in src/main/resources Just to clarify this subject... the logging.properties must go in WEB-INF/classes directory. If you are using some kind of framework for organizing your project, you must find out where to place the file in order to stay in WEB-INF/classes If you are using maven to organize the web app, you must know that everything that lies in src/main/resources goes to WEB-INF/classes. you

I am currently working on a program wherein, I must write all output to a log file. I need to write a log method, that should give an output with a level, a message, an object value, another message, an integer value, another message and another integer value, in the same order as I have specified. I can't seem to find a log method that does this. I am using Java.util.logging . Is this possible? I assume you need the log format in the below format FINE,Message1,object.GetValue(),Message2,1,Message3,2 You need to create an output message format logger.log(Level.INFO, "{0},{1},{2},{3},{4},{5}"

I want simply to log on the console using java.util.Logging: Logger log = Logger.getLogger("my.logger"); log.setLevel(Level.ALL); ConsoleHandler handler = new ConsoleHandler(); handler.setFormatter(new SimpleFormatter()); log.addHandler(handler); log.fine("hello world"); but this prints out nothing. What am I missing? Thanks Very simple, a logger can have several handlers, with each a different level. handler.setLevel(Level.ALL); Logging on the standard System.out stream could be easily done by adding a StreamHandler handler: logger.addHandler(new StreamHandler(System.out, new SimpleFormatter(

The NetBeans generate code like Logger.getLogger(svr.class.getName()).log(Level.SEVERE, null, ex); to output exception in catch.It will display in console. After I deploy my project,I cannot see any exception info.How to output those error messages to file and in console when console is available? Thanks folks. The logging system in NetBeans is based on the standard JDK's java.util.logging and complies to it as much as possible. In order to output error messages to a file, you can provide your own logging properties file on the classpath of your project. See the following links for more info :
