Tomacat 7, start don't work as command line start ?

Hi,

First of all, sorry for my bad English...

I just get Intellij Idea in trial to try it in real project, and maybe buy it.

I download a tomcat 7 server, and I try start it with command line "/Volumes/HDD/Workspaces/tomcat-7.0.27/bin/catalina.sh run", and all is OK, I could access to my project with http://localhost:8080.

I configure tomcat server in Intellij Idea, choose my tomcat home directory. In deployment tab, i choose my war, and in startup / connection tab I see that "Startup script" is the same command line that I run in my terminal.

But when I start tomcat with intellij there is not the same starting trace in the console, et finally it start very fast and http://localhost:8080 give me a blank page.

Could you help me for this problem ?

Thanks you.

Regards, Nicolas.
