java - Import JScience Measure into NetBeans -

i have basic question. trying use measurement functionality in jscience. downloaded .jar files (http://java.net/projects/jscience/downloads) created new library of .jar files loaded.

my "tree" is:

my import statement is:

import javax.measure; 

the compiler complains package javax.measure not exist. doing wrong?

thank you

the syntax importing in java is:

for individual class:

import com.mypackage.classname; 

for entire package:

import com.mypackage.*; 

to import entire measure package, can use:

import javax.measure.*; 

• using package members
