Diff between Server Library and Class library in Netbeans?

Question

Hi, What is the difference between Server Library and Class library in Netbeans?

Answer 1

A Server Library refers to a Application or Web Application library, a library like servlet-api.jar in Tomcat or jboss.all.jar in JBoss.

while

a ClassLibrary refers to a library outside the standard Server Library scope, like a log4j.jar. A class library is also a valid .jar class archive written by someone like yourself.
