Use Java Classes in Matlab

I have created a small Java CelsiusConverter GUI as described in http://docs.oracle.com/javase/tutorial/uiswing/learn/creatinggui.html. I would like to use the java classes contained in the compiled jar file in Matlab and view the gui through Matlab.

To do this I have added into the dynamic path the jar file

>> javaclasspath('-dynamic')

    DYNAMIC JAVA PATH

  C:\Users\user\Documents\MATLAB\Add JaVA classes\CelsiusConverterProject.jar

Furthermore, I have compiled the project in Netbeans using JDK 1.6.

Finally, I have attached the jar file that I have created.

Thank you very much in advance.
