You want to import that information from the JSON file into the current web page asynchronously. The JSON file is a file that contains information regarding name and value pairs. Maybe you have heard the following from a software/database engineer: I have a database application that works fine for a day and then stops working overnight.... This can happen to many database applications. In general, when you get a Connection object from database server, there is a timeout property associated with the Connection object; when this time expires, then the Connection object becomes stale/defunct (becoming a dead, useless Connection object). For example, the MySQL database closes connections after eight hours of inactivity. So, you either need to use a connection pool that handles stale connections or use the autoReconnect parameter. Using the MySQL database, automatic reconnection is available. Because the Connection object has to ping the database before each query, this is turned off by default. To use it, you need to pass autoReconnect=true in the connection URL. You may also change the number of reconnect tries and the initial timeout value via the parameters maxReconnects=n (the default is 3) and initialTimeout=n (the default is two seconds). The timeout is an exponential back-off timeout; in other words, if you have initial timeout of two seconds and a maxReconnects of three seconds, then the driver will timeout for two seconds, four seconds, and then sixteen seconds between each reconnection attempt.
