Hi Here is the server log file

Looking at the ERROR in the stack trace, there is an XML unmarshall exception.

12:58:57,826 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/suite]] (ServerService Thread Pool -- 180) JBWEB000287: Exception sending context initialized event to listener instance of class com.appiancorp.common.config.ConfigurationLoader: java.lang.ExceptionInInitializerError
...

Looking further at the stack trace, there seems to be a misconfiguration in your appian-topology.xml.

...
com.appiancorp.kougar.driver.ConnectionManagerConfigurator.createTopology(ConnectionManagerConfigurator.java:138) [appian-kougar-driver.jar:]

Review your appian-topology.xml and configure it per the Documentation.
