Getting message "invalid web viewer unzipped web application folder" 

Environment

• Output Management Web Viewer 12.1
• Apache Tomcat®

Cause

This problem results from a rare Tomcat deployment issue, but is easily rectified.

Resolution

From the appropriate webapps folder (under the Tomcat folder, eg.  delete the CAOMWebViewer12 and castylesr5.1.3 directories, then restart Tomcat so that new directories are created when the WAR files are deployed.

Additional Information

When CAOMWebViewer12.war and castylesr5.1.3.war are deployed absent the CAOMWebViewer12 and castylesr5.1.3 directories, Tomcat will create and populate new and correct CAOMWebViewer12 and castylesr5.1.3 directories.
