## This script simply tars and copies a webobjects bundle to a remote server and sets the permissions.
## It can be used for either an app bundle or split install bundle

# Argument passed in
## Example /Library/WebObjects/Applications/MyApp.woa
WOA_BUNDLE="$1"

## Example xmain2.remote (a ssh config alias in .ssh/config with key authentication)
## This ssh alias must have root access!!
SSH_CONFIG="$2"

## Example /Library/WebObjects/Applications
REMOTE_TARGET_DIR="$3"

## Target CHOWN
TARGET_CHOWN="$4"

## Target CHMOD
TARGET_CHMOD="$5"

USAGE="Usage: $0 /path-to-woa/myapp.woa root@ssh-alias /app/dir/on/remote appserver:appserveradmr 550"

# The script user on this machine needs to have dsa key access to root on target
# and the ssh configuration named here must be defined in script user's .ssh/config file
# Typically the TARGET_CHOWN should be "appserver:appserveradm"
