Importing jar files in neabeans

I've been used to simply importing jar files into my netbeans projects and then being able to import them in my projects. For example, I included the guava.jar. I saw it under libraries and when I expanded it, I saw things like com.google.common.. So, I just said import com.google.common. in my own classes and I was able to use their methods. Similarly for commons-math3-3.0.jar. But now I similarly included joptimizer-3.2.0-sources.jar (http://www.joptimizer.com/usage.html). When I expand it, I see folders like "src.main.com.joptimizer.functions" However, this time when I go to my projects and try to say import src.main..., it doesn't work they are not recognized. Why did simply importing the jars work before, but not in this case? And what do I need to do in this case to be able to use the methods in the joptimizer jar?

You included sources to you project. Sources means jar with not compiled *.java files.
You should add jar with compiled java classes (*.class files).

Looks like there is no compiled library on http://www.joptimizer.com/usage.html site and you should compile it manually.

Install maven tool, unpack joptimizer-3.2.0-sources.jar and execute 

mvn package

in the root directory (directory with pom.xml)
You will find compiled library in target directory
