Spectrum WebApp is inaccessible, with WebTomcat not starting. The following error is shown in the Browser console instead:
Request processing failed. Please refer the tomcat log for more details.
..Not able to reach OneClick Webapp. Process might be stopped. Please start the Spectrum WebTomcat Process and re-launch
Release : 20.2
Component : Spectrum OneClick
If the Spectrum Webapp was ever rebuilt/redeployed (during upgrade for example) and the old directory remains - then this needs to be removed.
Confirm there are no other directories under:
$SPECROOT/webtomcat/webapps/
Should just be "spectrum".
