We are trying to install ARD Hub on Windows; We have performed the activities as per the documentation on CA DOCOPS site. After starting the TOMCAT, the folders are getting created for respective WAR files; however, when we are configuring the ARD Hub from ARD, we are getting error "Unable to Contact config service". I have checked Tomcat and I can see the ARD components are not started. Request to please provide resolution on this.


Component: ARDOTH


In ARD logs, we noticed below error:
ERROR: *********** Caused by: java.lang.UnsupportedClassVersionError: org/springframework/web/SpringServletContainerInitializer : Unsupported major.minor version 52.0 (unable to load class [org.springframework.web.SpringServletContainerInitializer])
  This says, incompatible Jdk used by tomcat.


 Please install Java Jre 1.8 (1.7 and 1.9 are not supported) and as per ARD HUB requirement, please increase the memory (-Xms2048m -Xmx2048m) by following the steps given in below documentation

   Once the components are started, please login using administrator/marmite to ARD hub.
