Log errors, warnings and trace messages to the logger

The SRO records errors and warning messages such as the following:

• Serious errors such as exceptions, errors generated by the application object toolkit, incorrect data mapping, memory overflow, divide by zero are logged as errors (in red) in the Logger.

• Any error specific to the SRO are logged as warnings in the Logger, such as an error returned from the middleware.

• Errors that occur while recording the sample data in the MES database, such as the supplied sample ID does not exist in the database, are logged as a warning in the Logger.

• The warning messages from the database are logged as warning messages in the Logger. The messages are prefixed with Warning so that the actual error messages and warning messages are distinguished in the Logger.
