Class Not Found Exception(FX7500 SDK)

Hello Friends,

I have been trying to run the SDK provided by Zebra(FX7500 Embedded SDK Installer-1.2.2) following their guide.

the terminal window shows the "Listening at port 8998 ". But when I click to debug it just throw classNotFound Exception at Main class.

The attached picture depicts the scenario. Can u pls guide us on how to run this sample application?

Thanks in advance.
