解决了,马上给...关于数组的问题...(恼我3天的问题啊!)

<table width=100% border=2>
<logic:iterate id="element" name="models_picnames">
<table>
<bean:write name="element" property="key"/>
<logic:iterate id="elementvalue" name="element" property="value">
<tr>
<td>
<bean:write name="elementvalue"/>
</td>
</tr>
</logic:iterate>
</table>
</logic:iterate>
</table>
上面这是jsp页面....

rs1=db1.executeQuery(sql1);
while(rs1.next())
{
models_picnames[i][j]=rs1.getString("PICNAMES");
//!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!出错!提示:值=0
j++;
}
h.put("models_picnames"+i,models_picnames[i]);
i++;
}
request.setAttribute("models_picnames",h);
return mapping.findForward("indexsuccess");
}
}
我在运行时,提示 上面注释的地方值为0.
请高手帮我解决啊!....
这问题恼我3天了!
