Refs #529. Lab environment extension updated to report in the BASE window, when configuration file labenv-config.xml is missing, in which case the extension cannot start. Also, the configuration file is now reloaded every time the extension starts, even is the Tomcat server isn't restarted:

  1. Singleton class/file LabEnvironment updated with new new public method void reloadLabEnvironmentConfiguration(), for forcing a reload of the configuration file.
  2. Class/file LabEnvironmentConfiguration updated in private method void fetchConfiguration() to forward the contents of a caught exception as a RuntimeException, avoiding the need to declare that a number of methods in other classes throw exceptions.
  3. Class/file LabEnvService.java in src/net/sf/basedb/labenv/service/ updated in public method void start() to call new public method void reloadLabEnvironmentConfiguration() in class LabEnvironment, and to forward the contents of a caught exception as a RuntimeException, which doesn't violate the ServiceControllerAction Interface.
  4. Class/file LabEnvironmentServlet.java in src/net/sf/basedb/labenv/servlet/ updated in private method JSONObject createLabSensorConfigList(JSONObject json) to no longer forward exceptions thrown by the LabEnvironment instance recast as a ServletException.
  5. Class/file LabEnvironmentStatisticsServlet.java in src/net/sf/basedb/labenv/servlet/ updated in private methods JSONArray createLabEnvironmentDailyDistributionReport(JSONArray jsonStatisticsPlotArray, List<LabEnvironmentData> lthdList, Date startDate, Date endDate, String chartVariant, String viewType, String sensorName, String weekdayFilter) and String fetchChartTitle(String viewType, String variableType, Date startDate, Date endDate, String weekdayFilter) to no longer forward exceptions thrown by the LabEnvironment instance recast as a ServletException.
  6. Class/file LabEnvironmentStorageUtil.java in src/net/sf/basedb/labenv/util/ updated in public constructor LabEnvironmentStorageUtil() and public method List<LabEnvironmentData> queryLabEnvDb(Integer sensorNumber, Date startTime, Date endTime) to no longer catch exceptions thrown by the LabEnvironment instance and print its content to standard output.
