Hello Community,
I am trying to populate a drag down list the select the option. It is giving me an JspException:"Cannot find bean under name aDOrder". If possible please, take a look at the code and let me know what am I doing wrong and how the problem can be fixed???
Please, provide the elaborate answer, as I am newbie to the
Struts.
Thanks, in advance for taking out time for me. I really appreciate for the effort.
