Custom Java Button

I have created a Custom Java program to get the current date. The code functions properly outside CREO Schematics. I created a custom Java button and placed it on the Custom Ribbon tab. When I toggled

the button I get the "Error: Method call failed". I have placed my Date_Label.Class complied Java code in the

rsdesigner/utils directory where my CREO schematics was installed. I can't figure what is wrong.

Below is how I defined the button.
