You can launch JDeveloper by:


Launching JDeveloper

You can launch JDeveloper in one of the following ways:

By double-clicking the JDeveloper executable in the home directory of the JDeveloper installation

From the command line or a shortcut using the following command: <JDev Home>\jdev\bin\jdev.exe

By default, JDeveloper’s user directory is the same as the operating system’s user directory. In this user directory, user preferences, such as information about the appearance of the IDE, are stored. If you want to use a different directory, start JDeveloper with the –J-Dide.user.dir=<path> flag. The following example sets the user directory to the JDeveloper home directory: C:\Oracle\Middleware\jdeveloper\jdev\bin\jdev.exe –J-Dide.user.dir=c:\JDev

Another flag that you can use when you launch JDeveloper is –noreopen, which prevents JDeveloper from opening all the editor windows that were open the last time you closed JDeveloper. This can reduce JDeveloper’s startup time.
