Blank Browser Screen when logging into ZCC after Upgrading to 11.2.4

This document (7014121) is provided subject to the disclaimer at the end of this document.

Environment

Novell ZENworks Configuration Management 11.2.4

Situation

Upgrade to ZENworks 11.2.4 completed successfully
Blank browser screen seen after entering credentials to login to ZCC  (ZENworks Control Center)
The following error is seen in the zcc.log (full stack trace in Additional Information):

java.lang.NoSuchMethodException: com.novell.zenworks.fw.web.internal.Login.validateLanguageInput(java.lang.Object, com.novell.web.controls.ServerValidateEventArgs)

Resolution

The following file should exist on the primary server:

Windows: %ZENWORKS_HOME%\share\tomcat\webapps\zenworks\WEB-INF\lib\zcc-framework.jar
Linux: /opt/novell/zenworks/share/tomcat/webapps/zenworks/WEB-INF/lib/
zcc-framework.jar

When this issue was seen, there was an extra .jar file in the same directory:

Windows: %ZENWORKS_HOME%\share\tomcat\webapps\zenworks\WEB-INF\lib\zcc-framework-11.2.2.jar
Linux: /opt/novell/zenworks/share/tomcat/webapps/zenworks/WEB-INF/lib/
zcc-framework-11.2.2.jar

Do the following to resolve the issue:
  1. Stop the ZENworks services on the server
  2. Remove the zcc-framework-11.2.2.jar from the ZENworks file structure
  3. Start the ZENworks services again on the server

Additional Information
