Question

I am new to the Netbeans IDE and Java. I have a java project that shows lot of compilation errors:

can not import "org.apache.commons.logging.Log"

Can somebody please help me with these errors, How do I add library files in Netbeans IDE?

Answer 1

Quick solution in NetBeans 6.8.

In the Projects window right-click on the name of the project that lacks library -> Properties -> The Project Properties window opens. In Categories tree select "Libraries" node -> On the right side of the Project Properties window press button "Add JAR/Folder" -> Select jars you need.
