The two properties showInfoLevel and logFile are used for controlling debugs, errors and other displayed information. The following two methods are used to set values for these properties:
vDebug, vError and vOff are used for showing/turning off debugging information and error information. LogFileName specifies where the debugging, error and other information will go. LogFileName contains both the path and file name information. If no path is specified, the current path will be used. If no file name is specified, the file jreport_RF.log.* will be used.
