How to use jdbc with SQL developper : I'm trying to connect with my Eclipse program on my database in SQL developper.
I searched on the internet ,but there is just one video and it doesn't work.

Mine doesn't turn  like in the video.
I know I have to insert the following jdbc:oracle:thin@myserver:1521/demodb,but it doesn't work.
I think I have to provide a link between sql developper and eclipse ,but i don't know how.
PS:I have an account provided from school to use sql developper.
I can do that ,or it doesn't work?
