Once the ECC has been downloaded and the .WAR file has been added to the Apache Tomcat webapp, the .jar files for the UI will not load.
The download center only provides one set of .jar files that come with the download. The ECC requires version specific .jar files for the Automation.Engine_ui.plug-in_api
The .jar files from the disc image in the UIplugIn folder will need to be uploaded. Each version and build of the Automation Engine has a different .jar file in the UIplugIn folder.
