Answer 1

You need to add external jar file as :-

  Click Properties > Java Build Path > Libraries.
    Click Add External Jars and browse to the JAR file that contains the look and feel, then click OK. 
Now, you are ready to apply the new Look and Feel to your application.

Answer 2

You have add it to classpath as well. right click on project and click add to build project. click libraries tab and click external jar files. select your jar files. It will be added to classpath.

Answer 3

I think you have to inserti it. Rightclick in project properties build path, add external jar and browser to it.
