It seems rather silly to me that they would include this as part of their main library rather than as a separate, optional, jar. I suggest you contact the Selenium developers and, possibly, the SLF4J developers to find a solution. In any case, if you are going to have SLF4J in your classpath and want to use Log4j as the implementation, you should include the following in the classpath jcl-over-slf4j.jar slf4j-api.jar slf4j-log4j12.jar log4j.jar And get rid of any, and all, commons-logging jars. The jcl-over-slf4j.jar contains the package/classes of commons-logging, except they are a re-implementation bound to SLF4J. Jake I have just rewritten all selenium code to HtmlUnit code. That's it Works now. I know I should write to Selenium (I did, but they are silent) and lcf4j but after 25hours of me hugging 10 lines of code till blood and tears all go out... no I rather go the easy way now. No more fighting. I just hope HtmlUnit will do the job for me and that I will never have to use selenium... that's it.

It also contains the classes of an *older* version of slf4j-api.jar. Which explains the NoSuchMethodError exception about org.slf4j.spi.LocationAwareLogger.log method. Interestingly enough, selenium-server-standalone-2.21.0.jar released just a few hours ago does *not* bundle slf4j classes.

I thought about log4j.jar being in a different folder than httpClient but
it shouldn't matter since it's the classpath that rules over.
I am really out of ideas.

You *must* have something different than I do (something else on the classpath), but I can't think of what it is. I've made it work with both Eclipse Indigo and Netbeans 6.9.1.

Re: Log4J doesn't work at all
Selenium depends upon SLF4J. You may recall that I mentioned SLF4J in a previous email. In appears Selenium includes it's own SLF4J binding. It seems rather silly to me that they would include this as part of their main library rather than as a separate, optional, jar. I suggest you contact the Selenium developers and, possibly, the SLF4J developers to find a solution. In any case, if you are going to have SLF4J in your classpath and want to use Log4j as the implementation, you should include the following in the classpath jcl-over-slf4j.jar slf4j-api.jar slf4j-log4j12.jar log4j.jar And get rid of any, and all, commons-logging jars. The jcl-over-slf4j.jar contains the package/classes of commons-logging, except they are a re-implementation bound to SLF4J.

Re: Log4J doesn't work at all
woho! slf4j is in there! you have 2 copies of a slf4j binding loaded, one in the slf4j jar, one in the selenium jar. slf4j docs say it should use the first one found, which means slf should be binding to log4j. slf4j may be catching all the common-logging messages. You have a mess here: multiple versions of the same classes loading from different jars (httpclient, slf4j, commons logging). I wouldn't even hazard how to fix it with things in such disarray. Jacob was right: it's usually a classpath problem. Eliminating the duplicate jars (if you are using slf4j, the only commons-logging jar you need is commons-logging-api). I don't know how to keep the slf4j configuration bundled into the selenium jar from bunging up everything else. It's not HttpComponents that has the problem, and log4j is working just fine. I'd take it to the slf4j list if you continue to have problems... ■ DOUGLAS E.

Re: Log4J doesn't work at all
In reply to the questions: By Michael Erskine 1. I know this might sound daft but is your class actually trying to log anything? 2. Any luck with Log4J for a simple application? 3. Are you using HttpClient at the server side under Tomcat or as a standalone client? 1. Yes it does. I use: PropertyConfigurator.configure(./src/logging/log4j.properties); And shortly after logger.debug(some test message); just to test IF the proprties file was loaded and if it was loaded correctly. Yes it was. 2. logger.debug(some test message); - works. 3. Standalone client By Gary Gregory: 1. See Default Initialization Procedure 1. Just in case I added *log4j.defaultInitOverride=true *Didn't work. Also IF the configuration file specified by me was somehow overridden, then logger.debug(some test message); wouldn't work. And it works exactly as specified with configuration file I provided. I tested it with different levels than just debug level.
Re: Log4J doesn't work at all
I did this for a test: logger.debug(some test message); // - DOES get printed. my_code_here_based_on_HttpClient; // - should produce tons of logging output logger.debug(some test message); // - DOES get printed. So why the middle part doesn't produce any output? Just to recall I am using log4j.rootLogger=DEBUG, stdout so it shouldn't matter what and why. I am really puzzled now. Why the middle part doesn't produce any output?

Re: Log4J doesn't work at all
But I don't want to use commons-logging. I want to use log4j. You are missing the point. **You** want to use Log4j. That's fine. But HttpClient doesn't directly use Log4j. It directly uses commons-logging, which is a Logger adapter that supports various logging implementations, one of which is Log4j. If you want to use Log4j, then you ***have*** to use commons-logging.jar, and NOT commons-logging-api.jar, plus log4j.jar. To avoid commons-logging (and some of the problems it can create), you can skip commons-logging.jar and use SLF4J [1]: jcl-over-slf4j.jar + slf4j-api.jar + slf4j-log4j12.jar + log4j.jar. But either way, you can't avoid having the commons-logging packages/classes (which jcl-over-slf4j.jar mimics) in the classpath because HttpClient has a hard dependency on it. In any case, that System.property stuff didn't help either. Because it's commons-logging specific and totally irrelevant to Log4j. Besides, you were setting Log4j packages as properties and that is totally meaningless. For instance, you wrote... System.setProperty(log4j.logger.org.apache.http.client, DEBUG); But HttpClient's instructions say to do (again, read the instructions more closely)... System.setProperty(org.apache.commons.logging.simplelog.log.org.apache.http.wire, DEBUG); Part of the code simply gets. ignored. Why? Because you are not following instructions.

As far as classloading goes, on the libraries list, I put log4j at the top
and HttpClient right after it. The other jar that was using commons-logging

Re: Log4J doesn't work at all
In your other email you say... Running command line. From within NetBeans. No fancy stuff. Never discount the complexity of an IDE and how it forks JVMs and/or performs idiosyncratic classloading. In any case, your test below is invalid in this context. You claimed, in an earlier response, that you load your config manually using... PropertyConfigurator.configure(./src/logging/log4j.properties); The output you see from Log4j, ending with the line... log4j: Could not find resource: [null]. ...just means that Log4j default config lookup didn't find a Log4j config file in the root of the classpath. That's normal if you didn't put it there. But because you manually configure, your config is loaded, so you can ignore the above line. The one odd thing I see is that there is a logger named jobManager that is configured. I don't see that in the log4 config you posted in a previous response (see below). Are you sure the config file that is being loaded is the one you **think** is being loaded?

My output for System.out.println(httpClient.getClass().getClassLoader().getResource(log4j.properties)); is: null It seems the httpClient is not using the logger properties I specified. But I thought that's why there was this line: log4j.logger.org.apache.http=DEBUG in the first place. I am so confused.

Never discount the complexity of an IDE and how it forks JVMs and/or performs idiosyncratic classloading. I load/run only 1 JVM at a time. 1 Thread I might add. No forking here. In any case, your test below is invalid in this context. You claimed, in an earlier response, that you load your config manually using... PropertyConfigurator.**configure(./src/logging/**log4j.properties); The output you see from Log4j, ending with the line... log4j: Could not find resource: [null]. As the log4j debug stays, the file is being found and loaded after all. ...just means that Log4j default config lookup didn't find a Log4j config file in the root of the classpath. That's normal if you didn't put it there. But because you manually configure, your config is loaded, so you can ignore the above line. The one odd thing I see is that there is a logger named jobManager that is configured. I don't see that in the log4 config you posted in a previous response (see below). Are you sure the config file that is being loaded is the one you **think** is being loaded? First, I have to make it work. I can always add an entry in proprties file for a specific class later on. First it must work - then I will worry about details.

But it's on my super bottom list of worries. I first have to make it work. Then worry about the rest. That is bound to change from environment to environment and, therefore, brittle. Just stick it in the classpath and let Log4j pick it up. Has been already done sir ^^ Didn't help :( Jake :(

First, I have to make it work. I can always add an entry in proprties file for a specific class later on. First it must work - then I will worry about details. the log4j properties that you originally posted has nothing in it about jobManager; the output indicates that the one getting used does have settings for jobManager. Jacob has asked a question that may or may not be salient: are you sure the config file that is being loaded is the one you **think** is being loaded, or has the log4j.properties morphed along the way, and the file getting used is indeed the one that think is being used? You indicated that you were going to grab a fresh commons-logging jar and use it. Did you, or did that step get lost in the shuffle?
