Could Not Find the Main Class:

[JamesFitzgerald]

Hello,

I am learning how to use Eclipse and ArcGIS Runtime SDK for Java. I am having a problem. I have set up according to Create a simple map application—ArcGIS Runtime SDK for Java | ArcGIS for Developers. When I run the app, I get an error message 'Could not find the main class.JFJune. Program will exit. Any help will be appreciated.

Thanks

I have a question similar to yours, in my case, I don't get a pop-up but a message in the console:

Error: Could not find or load main class NewClass

On top of that, the option of adding toolkit.jar is greyed out. Any ideas why? Could it already be in there?
