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.

What does "mvn dependency:tree" give you?

This is code that run at startup and breaks on (LoggerContext) LoggerFactory.getILoggerFactory();

I am using Maven to keep track of dependencies, I have the following included for logback:
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-core</artifactId>
<version>0.9.15</version>
</dependency>

Hello Brian,

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

Hey guys,

I am noticing an error on startup:

java.lang.ClassCastException: org.slf4j.impl.SimpleLoggerFactory

I am trying to run the following lines to load my config, which
I got from the startup guide:

LoggerContext lc = (LoggerContext)
LoggerFactory.getILoggerFactory();
JoranConfigurator configurator = new JoranConfigurator();
lc.reset();
configurator.setContext(lc);
configurator.doConfigure(my_path);
StatusPrinter.printInCaseOfErrorsOrWarnings(lc);

The error occurs at the first line in the above code. I got
this working at some point, but somehow am back in a non-working
state. This is a Jetty app. Any tips?

Thanks,
Brian
