Automatic/Simple WebLogic Application Manipulation and Deployment Script Utilizing Bash

Today I come to you with a fun script I wrote to manipulate applications in WebLogic.

Using the weblogic.Deployer class in the WebLogic JAR we are able to Automate and Simplify some of the more mundane tasks that we all have to do in WebLogic sometimes.

For the savvy, please refer to the “prerequisites()” function and uncomment/comment whatever things you want the user to enter for proper security and portability.

Gotta love that dumb generic 1/2/3/4/5 menu interface I keep using.

Below is the code:

#!/bin/bash

#These Variables are here purely for initialization 
#and are overwritten when the prerequisites()
#function is called down at bottom of script

USERNAME=""
PASSWORD=""

ADMIN_URL="" #the url for deployment
JAVA_PATH="/usr/java/latest/bin/java" #path to java

WEBLOGIC_JAR="" #my weblogic server path
TARGET="" #values can be seperated
APPLICATION_NAME="" #the deployment name 
APPLICATION_PATH="" #the path to the ear file

WEBLOGIC_DEPLOYER_CMD="$JAVA_PATH -cp $WEBLOGIC_JAR weblogic.Deployer -verbose -debug -adminurl "$ADMIN_URL" -username $USERNAME -password $PASSWORD "

prerequisites()
{
    #In this command you can uncomment/comment variable declarations you want the user to enter every time

    echo "Type The Application Name: "
    read APPLICATION_NAME

    #echo "Type The Target JVM Servers (Space Between Each JVM Name): "
    #read TARGETS
    TARGETS="AdminServer"

    #echo "Type WebLogic Admin Username: "

    #read ADMIN_HOSTNAME
    ADMIN_HOSTNAME="localhost"

    #echo "Type AdminServer Port: "
