Jersey client with ignore ssl with proxy setting

Question 1

our can try urlconnection instead of jersey client which is much more easier than the jersey client

please find the below some code With the help of few stack overflow answer and Configure proxy to Jersey client, package org.app.last;

Question 2

You can use the http client with ssl connection which will give robust feature since it has built in feature so that it will take more adavantage for u. as per ur question which rest client u can opt jersey which is more easy one.
