Java SSH Library is the perfect library for making common SSH/SCP calls.  It even support SFTP.  I am using it in my management platform application.  I included the source package with mine, as well as the software license.  I hope that is adequate for anyone seeking to ensure I am not violating any laws in regard to sharing source.  I have also made a good effort to publicize my use of this code, as to not insinuate that it is in any way mine.

Elaborate Linux Script for determining IP

Sometimes the ordering of your Ethernet adapters are not the same on a specific machine vs the others in your cluster.  So simply grepping the IP based on adapter name can be a little tricky.  So I just made this script to do it for you.

#! /usr/bin/env bash
for network in $(cat /proc/net/dev | grep ':' | cut -d: -f1 | awk '{ print $1 }'); do
if [ "$network" != "lo" ]
echo $(/sbin/ifconfig $network | grep 'inet addr:' | cut -d: -f2 | awk '{ print $1}')

Clearly you could modify the if condition to fit your needs.
