Oracle 12c connection configuration errors I've installed Oracle 12c, and I'm trying to create a connexion using SQL Developer but I've got errors.

Here is the parameters after installation and users parameters:



Like in the photo, the port is 5500 but in tnsnames.ora I have this:

ORCL =
(DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

  PDBORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = pdborcl)
    )
  )


The port in here is 1521, so I'm confused which parameters use to create a connexion. It's my first installation of oracle.



I've changed the port to 1521. Now I've got this error:


  ORA-01017:invalid username/password; logon denied


I changed username to "system". It works on SQL Developer, but on the browser I don't know how to access.
You can use the following link to access Database Express through the browser:
