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.

When I removed

It started to work. However... I need selenium - it's my main browser. So
when I added it back....
SLF4J: Class path contains multiple SLF4J bindings.

And when I removed the extra slf4j
as
jar:file:/home/min/ucng/javaLibs/pbapi-full-1.4.0.91/lib/test/slf4j-log4j12-1.6.1.jar
Then I go back to a project that compiles but doesn't show output of
HttpClient logger.
Now I am like this @_@
What has some wierd slf4j to commons-logging or log4j. And what it has to
do with HttpClient... I am so so so so confused.
