Hi Manish,
I had the same issue, following a course on Udemy and I guess you are following the same as per the database name.
I managed to solve the problem entering the “system” username instead of the “webmuser” username in the “Create tablespaces and database user/Administrator” form. I hope I can continue with the learning and I didn’t messed something up.
PS. Also, I had to disconnect and reconnect the user in SQL developer to see the tables. A simple refresh didn’t help.
Have a nice day,
Magda
