I've got to run some old application that requires WebLogic 10.0.x. Could there possibly be a place where I can download it? If not, I'm considering buying it if possible. Your feedback is greatly appreciated.
The only place you can download WebLogic 10.0.x is via MOS (https://support.oracle.com).
You create a Service Request and they will provide you with a way to download the software.
This requires an active support contact.
