在JSP页面中设置JAVABEAN的INDEXED属性出错

javabean如下:  
  package   test1;  
  public   class   test1   {  
  int[]   ppp;  
  public   void   setPpp(int[]   parameter){  
  this.ppp=parameter;  
  }  
  public   int[]   getPpp(){  
  return   this.ppp;  
  }  
  }  
   
   
  jsp如下:  
  <jsp:useBean   id="MyTest"   scope="page"   class="test1.test1">  
  <jsp:setProperty   name="MyTest"   property="ppp"   value="{1,2,3,4,5,6}"/>  
  </jsp:useBean> 问题点数：20、回复次数：5Top

请问具体报的什么错误，可不可以贴出来？  
  由于没看但具体错误，我在这里大胆地猜测一下：  
  是不是在<jsp:setProperty   name="..."   property="..."   value=="..."/>中  
  传给bean对象的value只能是String类型（或者还有可以有些基本类型，但都是在后台从String类转过来的？），由于你输入的是"{1,2,3,4,5,6}"无法被解析成int[]数组型，所以会报错，如此说来报的错误应该大致是跟类型不匹配有关的。  
  本人是新手，胡乱猜测一番，希望楼主把具体错误帖出来验证下我的猜测看是否正确，谢谢。Top
