Thank you. Actually, I tried https://edelivery.oracle.com/, however, under 'Oracle Bea' or 'Oracle Fusion Middleware'. There is no weblogic 10.0 to let me download. Also tried other category, also no such download link, any idea?
As per the documentation on the Oracle site :
For existing customers requiring access to prior WebLogic Server versions, please refer to the
instructions at My Oracle Support Doc ID 1071023.1 ‘Requesting Physical Shipment or Download
URL for Software Media'.
10.3 falls in this specific scenario. Here is another link stating the same - http://www.oracle.com/technetwork/middleware/ias/downloads/bea-main-083206.html
So you need to open a SR with Oracle support which usually requires one to be a client of Oracle with client id.
