My way of deployment with WLST

This Script has ultimate goal to automate to one-step process for deploying the code onto WebLogic Development environment.

#paniDeployment.sh [Optional]
echo '***** WELCOME TO DEPLOYMENT SCRIPT *****'
user=`echo $LOGNAME`
echo 'APPLICATION DEPLOYMENT IS STARTING IN INSTANCE:' $user
DHOME=/Home/domains/wd$LOGNAME/config
WLHOST=`hostname`
cd $DHOME
WLPORT=`cat config.xml |grep listen-port|tr -s [:blank:] |tr " " "\n" |grep listen-port |cut -c14-17`
URL='t3://'$WLHOST':'$WLPORT
DENV=$HOME/domains/wd$LOGNAME/bin/setDomainEnv.sh
. $DENV $*
echo $CLASSPATH
#calling the paniDeployment.py file
java weblogic.WLST -loadProperties /Home/$user/.Admin/deploy.properties /Home/$user/.Admin/paniDeployment.py $user $URL$CLASSPATH 

Now let me give you what I did in my experiment with deployment script, I let you assume that 'a_ejb.jar','a_adapter.jar','b_adapter.jar','c.war' are the deployable components. You may have different components may be target to different WebLogic server instances or clusters it is your choice.

Well this might be very lengthy you might feel too much!! but this is my first time trial which I made ...



On our WebLogic many logics works hahaaaaaaaaaaaaaaaa

what are the argument to pass through this script..what are the deploy.properties file?.
