x4juli provides a native implementation for org.apache.commons.logging.Log interface and for the org.slf4j.Logger interface. x4juli uses the standard way of each facade to implement the corresponding factory. In case of Jakarta Commons Logging you still have to use the originally provided jar and put an config entry in the right place (System property or config.file). In case of slf4j you have to do nothing but remove all other sl4fj-xxxxx.jar files from the classpath.

This is an x4juli FAQ. Please have a look at the project pages for their documentation regarding usage in user code.

Second part: You have to make Jakarta Commons Logging use the x4juli JCLFactory. There are two possibilities: Specify a system property on your jvm startup (script): -Dorg.apache.commons.logging.LogFactory=org.x4juli.JCLFactory or put in an commons-logging.properties file in your classpath with org.apache.commons.logging.LogFactory=org.x4juli.JCLFactory property line in the file.

SLF4J is conceptually similar to JCL. As such, it can be thought of as yet another logging facade. However, SLF4J is orders of magnitude simpler in design and arguably more robust.

Adding supporting for the SLF4J is suprisingly easy. Essentialy, you coping an existing binding and tailoring it a little (as explained below) does the trick. Assuming your logging system has notion of a logger, called say MyLogger, you need to provide an adapter for MyLogger to org.slf4j.Logger interface. Refer to slf4j-jcl, slf4j-jdk14, and slf4j-log4j12 modules for examples of adapters.

There are many flight options for how to get to Jakarta. Please check with your local agent or on the internet to find a cheap and convenient route. We will meet you at the airport in Jakarta and bring you to the venue. But you will have to inform us of the exact date and time you will arrive and depart from the airport (including the flight number).

x4juli delivers all necessary classes as specified on http://slf4j.org/faq.html section "Implementing the SLF4J API". You simply have to remove all sl4fj-xxxxx.jar from the classpath.

Long answer: Java Commons Logging introduces a classloader hell that is discussed to some extend by the author of Log4J here and here. Thus, Coverlipse adds the Java Commons Logging package to those handled by the system classloader. This way, projects that use Java Commons Logging can be tested with Coverlipse. However, it is not possible to test the Java Commons Logging itself with coverage by Coverlipse. Again, this is a problem occurring only with Eclipse 3.0.

Shamans have power animals, friendly spiritual entities who help the shaman to do magical work. Power animals have no physical existence in the every day world. The Wiccan term for a power animal is "familiar." Not all Wiccans have them and they can be of any species. If you see a black cat in a Wiccan's house it is a black cat in a Wiccan's house, not a familiar.

Jakarta Struts is an application development framework -- a set of cooperating classes that constitute a reusable design. A framework dictates an architecture for the application -- its overall structure, partitioning into classes and objects, and how the classes and objects collaborate and their control.

SLF4J is a simple facade for logging systems allowing the end-user to plug-in the desired logging system at deployment time.

In short, libraries and other embedded components should consider SLF4J for their logging needs because libraries cannot afford to impose their choice of logging system on the end-user. On the other hand, it does not necessarily make sense for stand-alone applications to use SLF4J. Stand-alone applications can invoke the logging system of their choice directly. SLF4J is only a facade, meaning that it does not provide a complete logging solution.
