Getting started with WebLogic Server


Here are some quick tips on how to get started with WebLogic Server on Windows OS:

1. Download wls1212.zip from http://www.oracle.com/technetwork/middleware/weblogic/downloads/index.html
2. Unzip it under C:\apps\wls12120
3. set MW_HOME=C:\apps\wls12120
4. set JAVA_HOME=C:\apps\jdk1.7.0_51
5. cd C:\apps\wls12120
6. configure.cmd
7. mkdir mydomain
8. cd mydomain
9. %JAVA_HOME%\bin\java
-Xmx1024m -XX:MaxPermSize=256m weblogic.Server

By default, the last step should create a domain with all the nessary files in your current working directory. It will also prompt you to create a config.xml (enter 'y' to continue) and then prompting for a username and password to manage the server. Optionally you may also setup username/password part by using additional sys props like this:
-Dweblogic.management.username=weblogic -Dweblogic.management.password=Welcome1

Use CTRL+C to stop the server. The next time you start, you can just invoke "mydomain\bin\startWebLogic.cmd"

TIPS1: If you omit -Xmx1024m -XX:MaxPermSize=256m you will likely can start the server but as soon as you activate the /console webapp, you will run into out of memory issue.

TIPS2: If you have access, try to add Windows Environment variables for MW_HOME and JAVA_HOME into your system. If not, then you can easily add it into "mydomain\bin\setDomainEnv.cmd" as well (it's generated so you can edit all you like.) Without these two variables, you will likely get a class not found error.

TIPS3: The default server name created by this initial setup is called myserver. If you like to name it something else, then add sys props such as this: -Dweblogic.Name=admin-server 

TIPS4: To change the domain name from mydomain to something else, use: -Dweblogic.Domain=dev-domain

TIPS5: The default admin server listening port is 7001. To change this, use: -Dweblogic.ListenPort=7002
