struts.xml配置文件（相关部分）： 
<!-- UsersAction -->
		<action name="logon" class="UsersAction">
			<result>/manage.jsp</result>
			<result name="input">/failed.jsp</result>
		</action>


UsersAction相关部分代码： 
@Override
	public String execute() {

		if (action == null || "".equals(action)) {
			return ERROR;
		} 
	         else if ("logon".equals(action)) {
			return logon();
		} 
		return ERROR;
	}

其中UsersAction已经在applicationContext.xml中配置好；
运行时报错：
No result defined for action com.person.Action.UsersAction and result - action -，
不得其解，

pojo:
Order

public class Order implements java.io.Serializable {
private int id; //订单自动编号
private int orderId;
private String goodsname; //商品名
private int goodsid; //商品ID
private int count; //购买的数量
private Float price; //单价
}

Orders：

public class Orders implements java.io.Serializable{
private int id; //编号
private String username;//用户名
private int userid; //用户编号
private Date submitTime; //订单提交时间
private Byte ispay; //是否已付款
private int orderscore; //订单积分
private java.util.Set ordere=new java.util.HashSet();
/** }


Orders.hbm.xml: Orders主键自动递增，one to many Order，
Order对应的Order表中orderid 为外键,references Orders(id);

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="com.qinge.pojo">
<class name="Orders" table="eOrders">
<id name="id" type="java.lang.Integer">
<column name="Id" /><generator class="increment"/></id>
<property name="username" type="java.lang.String">
<column name="Username" length="20" /></property>
<property name="userid" type="java.lang.Integer">
<column name="Userid" length="" /></property>
<property name="submitTime" type="java.lang.Date">
<column name="submitTime" length="" /></property>
<property name="ispay" type="java.lang.Byte">
<column name="Ispay" length="1" /></property>
<property name="orderscore" type="java.lang.Integer">
<column name="OrderScore" /></property>
<set name="ordere" inverse="true" lazy="false"><key>
<column name="Id" precision="10" scale="0" /></key>
<one-to-many class="com.qinge.pojo.Order" /></set>
</class>
</hibernate-mapping>

像这个两个表插入数据市怎样保持关联？
我有疑惑：向Orders 表写数据时，id未知，向Order 表写数据是怎样确定orderId,以保证数据关联？

最近由struts1.x 转学struts2，发现变化好大，一个简单的demo都搞不定，
tomcat 访问 出现：The requested resource (/UploadSample/) is not available，，，

struts.xml配置: 
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
        "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
        "http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
			<package name="fileUploadDemo" extends="struts-default">

						<action name="myUpload"
									class="org.UploadAction">
									<interceptor-ref
												name="fileUpload">
												<param
															name="allowedTypes">
															image/jpg,image/bmp,image/png,image/gif,image/jpeg
												</param>
									</interceptor-ref>
									<interceptor-ref
												name="defaultStack" />
									<result name="input">
												upload.jsp
									</result>
									<result>showUpload.jsp</result>
						</action>
			</package>
</struts>


web.xml配置: 
<?xml version="1.0" encoding="gb2312"?>
<!DOCTYPE web-app
  PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
  "http://java.sun.com/j2ee/dtds/web-app_2_3.dtd">
<web-app>

			<display-name>struts2上传文件示例</display-name>

			<filter>
						<filter-name>struts-cleanup</filter-name>
						<filter-class>
									org.apache.struts2.dispatcher.ActionContextCleanUp
						</filter-class>
			</filter>

			<filter>
						<filter-name>struts2</filter-name>
						<filter-class>
									org.apache.struts2.dispatcher.FilterDispatcher
						</filter-class>
			</filter>



			<!--  注意顺序	-->
			<filter-mapping>
						<filter-name>struts-cleanup</filter-name>
						<url-pattern>/*</url-pattern>
			</filter-mapping>


			<filter-mapping>
						<filter-name>struts2</filter-name>
						<url-pattern>/*</url-pattern>
			</filter-mapping>

			<welcome-file-list>
						<welcome-file>upload.jsp</welcome-file>
			</welcome-file-list>
</web-app>


具体的类已经编译通过，
什么问题呢？
