Environment

AutoSys Workload Automation

Cause

WCC consists of several webapps, one of them is the rest webapp.  This rest webapp is not getting initialized because of the above error during the startup.  That's why no user can login anymore.

Checking the $CA_WCC_INSTALL_LOCATION/tomcat/webapps/rest/WEB-INF/lib  folder, it was noticed that there was an extra file present there.  spring.tar

Someone put an additional tar file (which contained some spring jar files) that were conflicting the ones that WebUI distributes

Resolution

1) delete the additional spring.tar file from $CA_WCC_INSTALL_LOCATION/tomcat/webapps/rest/WEB-INF/lib folder

2) compare the $CA_WCC_INSTALL_LOCATION/tomcat/webapps/rest/  files listing with a good/working server to make sure they look the same

3) restart CA-wcc-services service

 

This time WebUI lets the users login without errors.
