FIXED! I found the problem. The wrapper file listed the following problem… SLF4J: Class path contains multiple SLF4J bindings. Found binding in [jar:file:/usr/local/bin/ignition/tomcat/webapps/main/WEB-INF/lib/slf4j-log4j.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: Found binding in [jar:file:/usr/local/bin/ignition/tomcat/webapps/main/WEB-INF/lib/slf4j-log4j12-1.7.5.jar!/org/slf4j/impl/StaticLoggerBinder.class] Then this… SLF4J: slf4j-api 1.6.x (or later) is incompatible with this binding. SLF4J: Your binding is version 1.5.5 or earlier. SLF4J: Upgrade your binding to version 1.6.x. I guessed one of them may be an old one overshadowing the updated version. I assumed since the message said I had 1.5.5 and that one of the files was log4j12-1.7.5 that the other file was the offending one. I removed that file and restarted gateway and it is now functioning! ---

Thanks for the information. Glad you got it functioning. I will pass this information on to the developers. ---
