Question

I need to do a Http post of some strings to a web service. I am using KSoap.

@Override
protected JSONObject doInBackground(JSONObject... params) {
    String         


        

Answer 1

These errors often arise because the proxy failed to resolve a domain name into an address.

This problem is entirely due to slow IP communication between back-end computers, possibly including the Web server. Only the people who set up the network at the site which hosts the Web server can fix this problem.
