im having trouble deploying a war file on tomcat.

i have written a webapp in netbeans on my windows machine. it all runs fine. what i want to do is deploy the application on my linux computer that is acting as my server. once the application is built, i copy the war file from the dist folder in my project directory onto a pendrive. i then copy this onto the desktop of my linux computer.

i then start tomcat and using the application manager i browse the war file to deploy, then click deploy. i get a message at the top of the browser saying 'OK'. yet if i look at my tomcat output in the terminal window i have the following error:
