The /var/lib/netwitness/uax/logs/sa.log reports an error similar to the following:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'gzipResourceHttpRequestHandler' defined in ServletContext resource [/WEB-INF/mvc-servlet.xml]: Cannot resolve reference to bean 'buildInfo' while setting bean property 'buildInformation'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'buildInfo'
CauseThis issue can be caused due to the hostname containing non-alphanumeric characters, such as "_" , "." , "#", etc.

In order to resolve the issue, follow the steps below.

  1. Remove any non-alphanumeric characters from the hostname.
  2. Make sure your /etc/hosts, /etc/sysconfig/network and /etc/hostname files are set correctly and reflecting the new hostname.
  3. Reboot your appliance and the NetWitness UI should begin functioning normally after it fully initializes.
