Yesterday I have installed oracle database 10g XE and after installation I have created my own password and after that whenever I try to use sqlplus and then it asks for the username password.
SO for that I type username - system and password -(what I created)
but after that I am not able to login.
By the way I am able to use it in browser but I am not able to use it in sqlplus.
Help me please with it.
Here is the screenshot of the problem.

Plus I am also having one more problem and that is I am not able to use scott schema . Help me for that so that I can use that.
