Thread: why i cannot use this class if working with another workspace?

I want to make a program that uses some of the Java Media Framework classes. I have the following problem:
In this object declaration:

 private MediaLocator mediaLocator = null;

I use eclipse, and on one work space this works fine, does not show any error, but on the workspace on which i need to use this class which is from Java Media Framework, i get the following error:

Access restriction: The type MediaLocator is not accessible due to restriction on required library C:\Program Files\Java\jre7\lib\ext\jmf.jar

Why ? what should i do to fix this?
