classpath and cannot find symbol

I have been working on getting my first program (a simple one) to compile/run. I've tried to include javax.swing.JOptionPane however I am not sure where/why I can't get it to do so. I'm using linux and I'm sure the class must be in one of the jar files, but I can't seem to figure out how to point it in the right direction.

Any pointers would be much appreciated.

Thanks!!
