When trying to log on to WCC User Interface, the login page does not load and remains blank. No errors are displayed.
The problem was caused by a corrupted WCC Derby database. The following errors were recorded in the WCC logs:
INFO | jvm 1 | 2016/10/19 13:40:11 | SEVERE: Cannot get database connection
INFO | jvm 1 | 2016/10/19 13:40:11 | java.sql.SQLException: DERBY SQL error: SQLCODE: -1, SQLSTATE: XJ040, SQLERRMC: Failed to start database 'WCC_MAIN' with class loader sun.misc.Launcher$AppClassLoader@596b753, see the next exception for details.::SQLSTATE: XSAI2The conglomerate (16) requested does not exist.
