slf4j

SLF4J logger.debug() does not get logged in JBoss 6

Context: JBoss Application Server 6 I am relying on slf4j-jboss-logmanager.jar to bind slf4j to the JBoss log manager. All logger.info() output is correctly logged. However, logger.debug() output never appears in the log stream. Even though jboss-logging.xml has set the level to DEBUG for the CONSOLE logger... <console-handler n...

Wrapping the slf4j API

I want to retrofit slf4j with Logback into a legacy application. Good thing is, the legacy application has its own logging framework. So all I had to do is alter the logging framework to log to slf4j instead of log4j. It worked like a dream. I was happy, until I noticed the location Logback logged for each and every log event: Logger.j...

Logging framework incompatibility

I'm building a small Java app and hoping to use logback for logging. My app has a dependency on an older project that does its logging via org.apache.commons | com.springsource.org.apache.commons.logging | 1.1.1 ...so my plan was to use org.slf4j | jcl-over-slf4j | 1.5.6 ...to redirect the JCL logging to org.slf4j | slf4j-api ...

Further project A specifies slf4j-log4j12 version 1.4.2 as a dependency. I have another maven project B which depend on project A. In project B I have specified the following d...

What is a good way to handle slf4j logging in a web app deployed in Glassfish 3.0.1?

I have a quite ordinary web application which logs with slf4j, which is fine, and I have used several slf4j backends without any problems. Under Tomcat I just told logback to point at a location in the filesystem and log there, but now I want to deploy several independent instances of this application each in its own domain in a single ...

Is there any simple pattern of slf4j usage in unit tests?

I'm using JUnit4 and Hibernate3 in my project. Hibernate depends on Slf4j and thus my project includes this library as well. Now I'd like to use Slf4j in unit tests in order to log supplementary testing information. Could you please provide a short example of how my unit test should look like in order to log just one line of text? Prefer...

However, recently I started a new project by reusing some of the previous code base, and then I started to have some weird issues. <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.16</...

SLF4J Log Level as an argument.

Hi, We are looking to use SLF4J, but one thing we found was that you can't specify the level as an argument, i.e Logger.log(Level.INFO, "messsage"); You have to do this logger.info("message"); this prevents being able to pass everything through a method, so you can tack other properties to all log messages in a class. public cl...

There are three types of code in a GWT project: Client code (GWT client / javascript) Server code (servlet container / java) Shared code (GWT client & servlet container / javascript & java) Logging framework usable for each type: Client - gwt-log Server - slf4j Shared - ???

How to initialize slf4j (using log4j) logger properly in abstract classes / for inheritance

In my project I've got a top-level abstract class FrameProducer. I added a slf4j logger at this level, so that every inheriting class already has it. Here the code: public abstract class FrameProducer extends Observable { protected final Logger logger = LoggerFactory.getLogger(this.getClass()); protected BufferedImage frame; ...

Why calling LoggerFactory.getLogger(...) every time is not recommended?

Hi all, I've read tons of posts and documents (on this site and elsewhere) pointing that the recommended pattern for SFL4J logging is: public class MyClass { final static Logger logger = LoggerFactory.getLogger(MyClass.class); public void myMethod() { //do some stuff logger.debug("blah blah blah"); } } My...

Issues replacing Log4j with LogBack, log4j-over-slf4j.jar shortcomings

So I've been porting some of our services to use Logback over log4j and I've been using the log4j-over-slf4j jar to spoof log4j for our legacy dependencies. The only issue is log4j-over-slf4j doesn't implement many of the classes of log4j so I'm seeing a decent few class not found exceptions from dependent jars. How have people got aroun...
