Connect to remote phpMyAdmin

Question

I am trying to connect to a remote mysql server which is in phpMyAdmin through jdbc. I am not able to access the server.I am entering IP address and port no in my connection String.Is it possible to know the IP address and port no for the mysql server.Since i am not sure if the entered IP address and port no are correct.

I want to find the connection string of that database, in order to be able to communicate with my database using java.

Does anyone knows how to find that connection string?
