Let’s assume you want different JDeveloper versions using different JDK versions installed side by side on your dev environment. This how-to is about Windows but you can easily apply the steps to other operating systems, too.

Different JDKs

JDeveloper 12.1.3 and 12.2.1.2.0 may use different JDK versions. Indeed the following matrix applies:

JDeveloper min JDK version max JDK version
12.1.3 1.7.55 1.7.80 (*)
12.2.1.2.0 1.8 1.9

(*) Integrated WebLogic running on JDK 1.8 causes issues, like this.

Installing JDeveloper 12.2.1.2.0 side by side 12.1.3

  1. Install JDK 1.7 in some path without space characters within (like C:\Java7)
  2. Set system (not user) env vars for it
  3. Install JDeveloper 12.1.3 in a custom path without space characters within (like C:\Oracle1213)

  4. Open JDeveloper 12.1.3 and do not set to associate any file format to it.

  5. Install JDK 1.8 in some path without space characters within (like C:\Java8)
  6. Set system env vars for it (thus replacing 1.7)
  7. Install JDeveloper 12.2.1.2.0 in a custom path without space characters within (like C:\Oracle122120)
  8. Open JDeveloper 12.2.1.2.0 and do not set to associate any file format to it.

I hope it helped.

Thanks for reading.
