I want the log to roll over as long as the application is running, but I want the log to start fresh when the application is restarted. Updated: Based on erickson's feedback, my appender looks like this: <appender name="myRFA" class="org.apache.log4j.RollingFileAppender"> <param name="File" value="my-server.log"/> <param...
Is there a way to write log4j logging events to a log file that is also being written to by other applications. The other applications could be non-java applications. What are the drawbacks? Locking issues? Formatting? ...
It seems like v2 of Log4j has been in development for literally years. The Apache Log4J site no longer lists a roadmap, the dev mailing list seems almost entirely about 1.2 (which is appreciated!), use of v1.3 is discouraged, and the 2.0 branch is listed as "experimental". What's a believer to believe? ...
In the grails-framework some objects are using log. This is normally injected by grails. It works on execution of 'grails test-app'. But the same test (an integration-test) fails on execution of 'grails test-app -integration'. What goes wrong here and can I force the injection of the log-object somehow? ...
In logging frameworks like log4j & log4net you have the ability to log various levels of information. Most of the levels have obvious intentions (such as what a "Debug" log is vs. a "Error"). However, one thing that I have always been timid on was classifying my logging as "Fatal". What type of errors are so severe that they should be c...
I have an application for which log4j logging is configured in a log4j.properties file. Currently, this application runs on UNIX and creates a log file in /tmp. This application needs to run on Windows, and on that platform I would like for it to select the correct temporary directory, which I believe is C:\temp. How can I change my l...
We use Log4j (and Commons Logging) to log our error messages. Now we want to set up an additional log appender that outputs fatal errors to syslog, but without the exceptionally long Java stacktraces (those will still be available in the full log file). How would one configure this (using log4j.xml)? Is there a filter available to ignor...
Why one would use one of the following packages instead of the other? Java Logging Commons Logging Log4j SLF4j Logback ...

I am trying to figure out a clean way to intercept uncaught exceptions that occur in my application. I have log4j configured for logging the normal application flow and caught exceptions, so that is taken care of. Right now, I have a class that takes all error-level messages and adds them to a queue to be emailed in batches. Ideally,...
Hi I'm using log4j api for logging purpose. When I use the following code to append to the appender, it's showing "addAppender() is undefined for the type Logger" error FileAppender myAppender = new FileAppender(new PatternLayout(),"output.log"); Logger.getLogger(ConfigFileReader.class.getName()).addAppender(myAppender); Can anyone te...
I have an appender that I only want the first X characters (for this example, we'll say 5) of the message to display. I am using a PatternLayout but I can't get the message to truncate the message correctly. For example, if my log message is The quick brown fox I just want to see : The q When I use this in the Pattern ...
I haven't been able to find any documentation on how to configure Hibernate's logging using the XML style configuration file for Log4j. Is this even possible or do I have use a properties style configuration file to control Hibernate's logging? If anyone has any information or links to documentation it would appreciated. EDIT: Just to...
I need to instrument a series of .wsf and .vbs files with debug statements; before I go off and roll my own, does something like log4j exist for WSF/VBScript? ...
Where I work we use Log4j for web application logging. The log4j.jar is at the application level, not the container level. We're using a daily rolling file appender. Our log4j.properties files define appenders based on the app package name, so only classes in our application's package and below get logged to our app's log file. In ...
In the IntelliJ console, stack traces automatically contain hyperlinks that bring you to the relevant source files. The links appear at the end of each line in the format (Log4jLoggerTest.java:25). I can configure log4j to output text in a similar format. log4j.appender.Console.layout.ConversionPattern=%d{ABSOLUTE} (%F:%L) - %m%n In...
I have some questions about logging, more specifically about setting it up and making sure it works. The project I'm doing will use Wicket, Spring and Hibernate. I know that Wicket and Hibernate uses Simple Logging Facade for Java (SL4J) and that Spring is using the logging component from Apache Commons. Will they co-exist happily? I t...
I'm attempting to upgrade from Hibernate 3.2 to 3.4, which apparently uses slf4j. Our project currently uses log4j. So my assumption is that I should be using the slf4j-log4j12 wrapped implementation. The Maven slf4j dependency is: <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>1....
Hey to all Java has a lot of frameworks / APIs that help you do logging in your application: The Java API has java.util.logging package. Apache's Log4j. Apache's Commons Logging. SLF4J (logging Facade). jLo. and many many more... I've always used the log4j library, i found it sufficient most of the time, and extensible when i needed...
