I hav developed a simple program which is updating the node value to whatever user gives the input. I want to run the multiple instance of the same program so that if one instance modifies the value the other instance of the same program should get the updated value. What needs to be done extra apart from writing the code? Will I have to use app server? Currently I am running many instance of the program from eclipse but other instance are not getting the updated value. Thanks in advance. Looking forward for yours input.
