The most common reason for this sort of thing is that you have 
incorrectly mounted your source in NetBeans.

If you mount the directory:

    /home/jsn/.public-html/Classes/22c:021/Project_1

and try to compile from within NetBeans, this should solve the problem.

The reason for the issue is that each directory you have mounted is 
added to your classpath.  To NetBeans, your
interface's fully-qualified name probably looks something like 
"Project_1.MatrixInterface" (the class MatrixInterface in the
Project_1 package), which is different than "MatrixInterface" (the class 
MatrixInterface in the default package).

If you correct your mount point (i.e., classpath), all should be well.

Hope that helps.
