<s:iterator>应用

public String execute(){ 
  list = new ArrayList<UserInfo>(); 
  UserInfo userInfo = new UserInfo(); 
  userInfo.setUsername("u1"); 
  userInfo.setPassword("p1"); 
  userInfo.setRoleInfo(new RoleInfo("r1")); 
  list.add(userInfo); 
  userInfo = new UserInfo(); 
  userInfo.setUsername("u2"); 
  userInfo.setPassword("p2"); 
  userInfo.setRoleInfo(new RoleInfo("r2")); 
  list.add(userInfo); 
} 
<s:iterator value="list" var="var"> 
    <s:property value="#var.username"/> 
    <s:property value="#var.password"/> 
    <s:property value="#var.roleInfo.rolename"/><br> 
</s:iterator> 
或者： 
<s:iterator value="list"> 
    <s:property value="username"/> 
    <s:property value="password"/> 
    <s:property value="roleInfo.rolename"/><br> 
</s:iterator>

数组（普通属性） 
public String execute(){ 
  strs = new String[2]; 
  strs[0] = "as"; 
  strs[1] = "asd"; 
} 
<s:iterator value="strs"> 
    <s:property/><br> 
   </s:iterator> 
或者： 
<s:iterator value="strs" var="var"> 
    <s:property value="var"/><br> 
   </s:iterator>
