I define a CartAction class which extends a DispatchAction as follows:
public class CartAction extends DispatchAction
I define a method in CartAction :
public ActionForward addWare(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
in the file struts-config.xml,the raletive configuration is as follows:
<action
input="/order/cart.jsp"
parameter="action"
path="/cart"
scope="request"
type="org.apache.struts.actions.DispatchAction">
<forward name="success" path="/order/cart.jsp" redirect="true"/>
If I type in http://localhost:8080/eBuy/cart.do?
The error message turned out to be :
javax.servlet.ServletException: Request[cart] does not contain handler parameter named 'do'. This may be caused by whitespace in the label text.
If I type in http://localhost:8080/eBuy/cart.do?action=addWare
The error message is:
java.lang.IllegalArgumentException: Path http://localhost:8080/eBuy/cart.do does not start with a "/" character
