After an Oracle Connector Console update, a 404 page is seen when attempting to log in with the following message:

Servlet JSP not found

Further errors can be seen when starting the Oracle Connector service, but the error may not be apparent when run as a service.  

In this document, the variable %CONNECTOR_HOME% is a place holder for the Oracle Connector installation directory. The default for this directory is C:\Program Files\Loftware Labeling\Connector.

Using startup.bat from the %CONNECTOR_HOME%\console\bin folder displays:

SEVERE: Null component Catalina:type=JspMonitor,name=jsp,WebModule=//localhost/ConnectorConsole,J2EEApplication=none,J2EEServer=none.

This indicates that some .jar files are leftover from the previous version.


A repair alone (installation>>repair) may not solve the issue.  The console directory under %CONNECTOR_HOME% will need to be renamed or deleted before the repair.  

How to Implement the Solution 

  1. Make sure the Oracle Connector service is stopped (use %CONNECTOR_HOME%\console\bin\shutdown.bat or services.msc to make sure the Windows service is stopped).
  2. Rename %CONNECTOR_HOME%\console to %CONNECTOR_HOME%\console_old.
  3. Run a repair type installation of the Connector Console.  (C:\Program Files\Loftware Labeling\Connector\_Loftware Connector for Oracle_installation\Change Loftware Connector for Oracle Installation.exe)
  4. Ensure there is a new %CONNECTOR_HOME%\console created.
  5. Run %CONNECTOR_HOME%\console\bin\startup.bat, make sure there are no SEVERE error messages.
  6. Log into the Connector Console to ensure that it is available.
  7. Delete the %CONNECTOR_HOME%\console_old folder (your option).


After renaming the console folder and then repairing the Connector Console, the Connector Console should be available and respond normally.
