Java Development Tools

Hi,
I built an application which was used to test HTB ETS service. There are two projects, one is Model, the other is ViewControl.
In Model, I wrote two beans: DrugTestBean was to login HTB and display all the concept list, and DrugTestControlBean was to return an instance of DrugTestBean.
In ViewControl, there was a jsp page. It had a ADF Command Buttom binding with DrugTestControl.DrugTestBean.displayConceptList.

After running the page, I got the following exception:

Do I need some jar to add into my project? Or any other reasons?

Many Thanks!
