    I apologize for forgetting to check the class name in a list. It's possible that my mouse accidentally slid and changed the class name.
    Now it's work.

    Calling a report data provider (RDP) class from a menu item doesn't look normal to me. What are you trying to achieve by that?
     
    These classes are called by the reporting framework when a report executes and it needs to fetch the data. If you want to to run the report, call its controller class, not the RDP class.

    I'm assuming that you run the project. The first one calls HSTStockCard menu item, the other HSTStockCardData. I don't know what these menu items call and which of them is failing, but it seems that one of tries to calls class xxxx and it can't, because it requires the class having main(Args) method, which it doesn't have. Either you shouldn't call the class or you need to add main(). If it's about the data provider class, calling it by a menu item doesn't make good sense to me.
