Hi Joakim,
thank you for your reply.
Your the first and the second suggestions are based on Jetty 7+ with
standalone server but I as I wrote before I have Jetty 6 started from
the Maven plugin so these options are not available for me. But the 3rd
one is great. I have read your example and used it. It perfectly works,
problem solved.
Thank you a lot for your help.
Best regards,
Karel

Hi,<br>
<br>
I would like to jetty log using SLF4J. It works for direct
logging through<br>
SLF4J and for logging using apache logging commons but it
doesn't work for<br>
java.util.logging. I am starting jetty from maven plugin and
I use the<br>
plugin version 6.1.26. I have jul-to-slf4j in dependencies
in a version<br>
1.6.6. The JUL logging properties contains only definition
of<br>
org.slf4j.bridge.SLF4JBridgeHandler to be a handler.<br>
<br>
My problem is, that the Jetty still says, that<br>
<br>
Can't load log handler "org.slf4j.bridge.SLF4JBridgeHandler"<br=

<br>
<br>
<br>
<br>
<br>
<br>
and I don't know why, because all necessary slf4j modules
are defined in<br>
dependencies.<br>
<br>
I would like ask for any help that bring me to working
bridged logging from<br>
JUL to SLF4J. It seems to be a classloader problem.<br>
<br>
Thanks a lot,<br>
