Database Software

Hello,

I am new to oracle database. I am trying import a data dump file *.dmp into my test database. I am using Oracle Database 11g. I have created "datatest" to be the user and I granted all possible rights that was there. :) but still getting this error message.

Does Oracle has a GUI tool somewhere I can try or how I can fix this issue? PLEASE HELP.

Below are the actions taken:
