I am getting the following error when I try to set the name and type
attribute of the <html:form> tag. I have included a snippet of my login.jsp
file and my struts-config.xml file
The main reason I am trying to set them is because if I don't set them and
let the form tag configure itself with the appropriate bean, the action
attribute on the form is empty
(action="") . If someone can explain why the action attribute is not being
set then I will not worry about having to try to set the name and type
attributes of the form tag.
Any help with be greatly appreciated.
