webwork中有关从action中提取数据的问题!!

[lht0731]

在action中执行查询，用List变量来接受查询结果集，现在想要把List变量所接受到的结果反馈到页面（jsp页面）上．用webwork标签试过不好使，无法将查询结果反馈到页面上．（在控制台可以正常输出查询结果）
action:
public class GetTopTypeAction extends BaseAction {
private Type type;
private List types = new ArrayList();

public String execute(){
TypeFacade facade=(TypeFacade)ServiceLocator.getInstance().getService("TypeFacade");
this.setTypes(facade.getTopTypes());
System.out.println(types.size());
System.out.println(types);
//this.Session.put("types",types);
return SUCCESS;
}
public Type getType() {
return type;
}
public void setType(Type type) {
this.type = type;
}
public List getTypes() {
return types;
}
public void setTypes(List types) {
this.types = types;
}

}
jsp中:
<ww:iterator value="types" status="status">
aaabbbb
<ww:property value=”#status.count”/>
<a href="b.jsp"><ww:property value="typeName"/></a>
<a href="b.jsp"><ww:property value="typeId"/></a>
</ww:iterator>
