When logging into the Spectrum OneClick web pages and selecting some of the links, some pages show an error similar to the following instead of the expected information from the link.
Release : Any
Component : Spectrum OneClick
This is caused by left over jar files after upgrading from a previous version of Spectrum.
Check the $SPECROOT/tomcat/lib directory for jar files that do not have the same date as others. Specifically, a date that is earlier. When found, move these files out of the $SPECROOT/tomcat/lib directory and restart tomcat.
If you are not sure and have another OneClick system that is not displaying this issue, compare the jar files from the system where you are not seeing the issue with the jar files from the system where you are seeing the issue.
