如何使用超链接将数据发送到servlet

Question

我需要使用超链接将数据发送到servlet。但是，当我单击此取消按钮时，出现此错误“ HTTP状态404-/ SujaneeRestaurant / orderId = 13 / CancelCater”。我该如何解决？

<a href="orderId=<%=resultSet.getString("orderId")%>/CancelCater" 
class="btn search_toggle"> Cancel </a>


<servlet>
<servlet-name>CancelCater</servlet-name>
<servlet-class>CancelCater</servlet-class>
</servlet>

<servlet-mapping>
<servlet-name>CancelCater</servlet-name>
<url-pattern>/CancelCater</url-pattern>
</servlet-mapping>
