When you installed XE.... it automatically created a database called "XE". You can use your login "system" and password that you set to login.
Key info
server: (you defined)
port: 1521
database: XE
username: system
password: (you defined)
Also Oracle is being difficult and not telling you easily create another database. You have to use SQL or another tool to create more database besides "XE".
