I have been using the Oracle Cloud Service for the last 10-15 days. I deployed a JAVA Web service application which is connected with the Oracle Cloud Database. I am consuming that web service in my Oracle ADF Mobile Application. But when I try to request the any web method of the service more than 4-5 times then the database connection goes unavailable and it respond me NullPointerException. After 10-15 minutes, The Database connection is available but when I request again more than 4-5 times to any web method of Web service then I face same issue.
I have been facing this problem for last 2-3 Days.
