WebObjects Error

Application: Result
Error: java.lang.IllegalStateException exception
Reason:
java.lang.IllegalStateException: An Exception occurred while generating the Exception page 'WOExceptionPage'. This is most likely due to an error in 'WOExceptionPage' itself or WebObjects encountered an uncaught exception while creating a Session object.

Below are the logs of the original Exception which occured in Application, then the later Exception in WOExceptionPage.

Original Exception:
java.lang.IllegalStateException: _obtainOpenChannel -- com.webobjects.eoaccess.EODatabaseContext com.webobjects.eoaccess.EODatabaseContext@bfe3f0e: no database channel is available.
