netbeans6.8 - Netbeans web application - excluding the JAR while building the WAR -

I am using Netbeans IDE for the development of web applications and I have some JAR application available in the server, which There is a need to be with the war, but we need to compile and run them locally. What is the option to exclude jar file in Netbeans while creating a war file?
