Starting with the 7.4 version of Thingworx, a license.bin file locked to the specific version of Thingworx is required in order to successfully start the Thingworx webapp. If something is wrong with the licensing, Tomcat will crash and will not show any information regarding the problem in its log files. The Catalina*.log file will look like this

 

13-Jun-2017 04:36:43.268 INFO [main] org.apache.catalina.core.StandardService.startInternal Starting service Catalina

Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.

 

instead of continuing on through the rest of the war files present on the server as it would if everything worked properly.

The error will actually be in the ThingworxStorage/logs/ApplicationLog.log file - something like this:

Get your license installed properly and the problem should go away.
