Title: RE: [jdjlist] Log4j vs. 1.4/JSR47 Logging API

I agree w/ Martin. The biggest reason to favor Log4J is it's availability in pre-1.4 environments. Most of the significant issues from the apache critique were addressed in later versions of JDK logging. (The current version is here: http://jakarta.apache.org/log4j/docs/critique.html)

 

You might want to wrap the API. They are so similar that it's easy to create a common interface & plug-in the API you want @ run-time. That's what I've done in the past and it's works great for switching APIs later. You might also look at the apache commons project which provides similar wrapper logic for different logging packages. (http://jakarta.apache.org/commons/logging.html)

Hi Alastair,

One problem that I have come across is that using the APIs from 1.4 requires you to use the appropriate environment, i.e. 1.4. Most Application servers, apart from the open source ones, such as Tomcat and JBoss support previous versions of the environment 1.2 and 1.3. If you are not presented with this problem, I can't offer a detailed opinion on the benefits of using the one versus the other. In a distributed environment you may not have this problem, or if you are not using an application server this is also not a problem as long as you are not restricted by the use of the appropriate environments.

We are currently using Log4J, but this is purely based on the fact that the decision was made before the APIs of 1.4 were available.

Hope this helps
Martin

Hi,

I'm trying to decide whether to use Log4J or the Java 1.4 logging API (JSR47) in a distributed J2EE app.

I've read a lot of opinions expressed favouring Log4J over 'standard' Java 1.4 logging, but most of what I've read seems to be quite old and was written before the final release of the 1.4 API, e.g. http://www.ingrid.org/jajakarta/log4j/jakarta-log4j-1.1.3/docs/critique.html, and I think some changes may have been made to the 1.4 spec as a result of the criticisms.

Can anyone give me an informed opinion of whether there is still such a great difference between these two frameworks, and which they would recommend?

Thanks,
Al.
