Where deploying directory of embedded Weblogic is?

When you run an Fusion ADF application in JDeveloper, it is deployed behind the scenes in the embedded Weblogic (WLS) in order to run. The directory that your application is deployed  is located under

%JDEV_SYSTEM_ROOT%\o.j2ee\drs

where JDEV_SYSTEM_ROOT is JDeveloper's system directory and its default value is:

C:\Documents and Settings\username\Application Data\JDeveloper\

so the default place is:

C:\Documents and Settings\username\Application Data\JDeveloper\\o.j2ee\drs

Under directory drs  you ll find a directory (with the same name as the application) for each application that you have deployed.

Why you need to know that?
Sometimes the deployed application is not refreshed with new changes and you ll need it to clear it n order to be recreated from scratch.

Note 1:

Make sure to change username with your Windows user.
