Hi all:
I am trying to get this simple example working, I included all the jars in
apache-log4j-2.0-beta4-bin
import org.apache.logging.log4j.LogManager;import
org.apache.logging.log4j.Logger; public class HelloWorld { private static
Logger logger = LogManager.getLogger("HelloWorld"); public static void
main(String[] args) { logger.info("Hello, World!"); }}
Here is the exception I am getting in eclipse:Exception in thread "main"
java.lang.NoClassDefFoundError: org/slf4j/spi/LocationAwareLogger

org.apache.logging.slf4j.SLF4JLoggerContext.getLogger(SLF4JLoggerContext.java:39)

Then I've added slf4j-api-1.7.2.jar. I've still couldn't get it working with
what looks like a non-terminated recursive loop eventually overflowing my
