修改数量
页面：

<form action="/commerce/cart.do?method=update" method="get">
  <table>
    <tr>
     <td>数量</td>
    </tr>

<logic:iterate id="cartItem" scope="session" name="Sessio nContainer" property="cart.items">
<tr>
<td><input type="text" name="qty_<bean:write name="cartItem" property="id"/>" value="<bean:write name="cartItem" property="quantity"/>">
</td>
</tr>
</logic:iterate>
<tr>
<td colspan="1" align="center">
<html:submit></html:submit>
</td>
</tr>
</table>
</form>

action：

public class GetItemDetailActions extends CommerceDispatchAction {
public ActionForward update(ActionMapping mapping, ActionForm form,
      HttpServletRequest request, HttpServletResponse response) {
    // TODO Auto-generated method stub
    updateQuantity(request);
    return mapping.findForward("success");
  }

  private void updateQuantity(HttpServletRequest request){
    SessionContainer sessionContainer=this.getSessionContainer(request);
    Enumeration enum1=request.getParameterNames();
    while(enum1.hasMoreElements()){
      String ids=(String)enum1.nextElement();
      if(ids.startsWith("qty_")){
        String qtyString =request.getParameter(ids.substring(4,ids.length()));
        sessionContainer.getCart().updateQuantity(Integer.parseInt(ids), Integer.parseInt(qtyString));
      }
    }
  }
}

struts-config。xml

<action
  path="/cart"
   scope="request"
   type="commerce.action.GetItemDetailActions"
   validate="false"
   parameter="method" >
    <forward name="success" path="/commerce/cart.jsp"></forward>
</action>

异常：
javax.servlet.ServletException: Request[/cart] does not contain handler parameter named 'method'. This may be caused by whitespace in the label text.
