Description

http://tapestry.apache.org/tapestry5/tutorial1/first.html

When I tried to run Jetty from Eclipse, I got exception:

[ERROR] RequestExceptionHandler Processing of request failed with uncaught exception: org.apache.log4j.Logger.isTraceEnabled()Z
java.lang.NoSuchMethodError: org.apache.log4j.Logger.isTraceEnabled()Z
at org.slf4j.impl.Log4jLoggerAdapter.isTraceEnabled(Log4jLoggerAdapter.java:81)
at org.apache.tapestry.internal.services.RenderQueueImpl.run(RenderQueueImpl.java:50)

Google helped me to find the fix:

> It is necessary that you upgrade the copy of log4j inside Jetty to version
> 1.2.14. That adds the isTraceEnabled():boolean method that SL4J expects.

Please add this 2 lines to the documentation, it will help people to save time.
