java.util.logging

I'm compiling a PDF using iText and Flying Saucer, and unfortunately, I can't seem to get any output from Flying Saucer when compiling. I'd really like to be able to see what's going on internally so as to be able to debug the current problem I'm facing. How can I turn on java.util.logging for Flying Saucer? I'm currently using SLF4J/Logback. Found it: System.getProperties().setProperty("xr.util-logging.loggingEnabled", "true"); XRLog.setLoggingEnabled(true); 来源： https://stackoverflow.com/questions/9729147/turning-on-flying-saucer-java-util-logging-output

I need some direction in configuring the log format in Tomcat 7. I am relatively new at logging configurations so please excuse humor this questions if it seems a bit basic... Using the standard logging in Tomcat configured in logging.properties displays a log in the format of: Jun 6, 2011 9:27:00 AM com.class.Control_WS callWebService INFO: Response received from Control_WS:[Y] I would like to customize these logs to compress on to one line as well as expanding the date format to include milliseconds. Example: [2011-05-04T11:37:00.037|INFO|javax.enterprise.system.stream.out|Response recieved

I am working on a project that uses GAE as the backend for a mobile app. We want to have really good logging implemented in the project. I have spent a lot of time reading about log4j, logback-classic, logback-access, java.util.logging (JUL) and slf4j. My conclusion is that I want to use logback-access since it has some nice features when it comes to logging http related stuff (e.g. logging full-request-data upon errors etc.). Since GAE only supports the log levels for JUL and logback-access does not support slf4j, I thought that I should just install logback-access and make sure it writes all

could anybody explain to me, how to set up java Logger for various classes from a concrete package ? for example: if I get this one and set it up Logger logger = Logger.getLogger("com.google.api.client.*"); logger.setLevel(Level.CONFIG); logger.addHandler(new Handler() { @Override public void close() throws SecurityException { } @Override public void flush() { } @Override public void publish(LogRecord record) { // default ConsoleHandler will take care of >= INFO if (record.getLevel().intValue() < Level.INFO.intValue()) { System.out.println(record.getMessage()); } } }); there are conditions

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 also redirect stdout to a separate file to catch thread dumps and similar. This results in about 200
