# JMRI: Tables Servlet

The JMRI Tables Servlet provides web access to information about JMRI objects such as Turnouts and Sensors.

This servlet responds to the following URL patterns:

/tables/
/tables/type
  Lists all potentially supported data types (in a table).
/tables/<type>
  Displays an operating list of objects of that type (or "No data for this table." in case of an empty list).
  The table updates dynamically to reflect changes in JMRI. Click the State column entry to toggle the state of that item in JMRI.
  <type> is one of: turnout, sensor, route, reporter etc.
