JDeveloper 11g default weblogic user’s password
When JDeveloper 11g is installed, once you test your application in default server engine in JDev, JDeveloper will create a new domain “Default Domian” and use the default weblogic server to test the applications developed.
The defaut administrator (weblogic) password for Weblogic Server is “weblogic1”.
BTW, the default user and password is located in the boot.properties file under this folder: ../Application Data/JDeveloper/system11.1.1.1.33.53.92/DefaultDomain/servers/DefaultServer/security.
