Could you post the whole stack trace please (including nested exceptions)? I thought that a few lines would be sufficient but that is not the case.<br>
<br>
What does "mvn dependency:tree" give you?<br>

Hello Brian,<br>
<br>
Could you please post the two or three lines of the stack trace?<br>
Which artifacts (jar files) have you placed on the class path?<br>

Hey guys,<br>
<br>
I am noticing an error on startup:<br>
<br>
java.lang.ClassCastException: org.slf4j.impl.SimpleLoggerFactory<br>
<br>
I am trying to run the following lines to load my config, which<br>
I got from the startup guide:<br>
<br>
LoggerContext lc = (LoggerContext)<br>
LoggerFactory.getILoggerFactory();<br>
JoranConfigurator configurator = new JoranConfigurator();<br>
lc.reset();<br>
configurator.setContext(lc);<br>
configurator.doConfigure(my_path);<br>
StatusPrinter.printInCaseOfErrorsOrWarnings(lc);<br>
<br>
The error occurs at the first line in the above code. I got<br>
this working at some point, but somehow am back in a non-working<br>
state. This is a Jetty app. Any tips?<br>
<br>
Thanks,<br>
Brian<br>
