html:multibox的有关问题

热度:63   发布时间:2016-04-17 14:55:54.0
html:multibox的问题
JSP页面代码如下:
        <logic:iterate   id= "element "   name= "admins ">
        <tr>
        <td   align= "center "> <html:multibox   property= "selectedActions "> <bean:write   name= "element "   property= "id "/> </html:multibox> </td>
        <td   align= "center "> <bean:write   name= "element "   property= "id "/> </td>
        <td   align= "center "> <bean:write   name= "element "   property= "pwd "/> </td>
        </tr>
        </logic:iterate>

我想在Action类里把selectedActions的第一个值取出来,应该怎么做?
我是这样写的:
String   boxList[]   =   AdminForm.getSelectedActions();
String   user_id   =   boxList[0];
但是不行,在String   user_id   =   boxList[0];这一行报错:java.lang.ArrayIndexOutOfBoundsException
似乎是数组越界的问题?请教各位高手应该怎么做,在线等

------解决方案--------------------
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
// TODO Auto-generated method stub
List list=coursedao.findAllCourses();
request.getSession().setAttribute( "courses ",list);
return mapping.findForward( "showall ");
}


<body>
<html:form action= "/mySelect " method= "post ">
<center> <bean:message key= "message.system.ui.showCoursesForm.allCourses "/> </center> <br>
<logic:iterate id= "course " name= "courses " scope= "session ">
<html:multibox property= "courses ">
<bean:write property= "couId " name= "course "/>
</html:multibox>
<bean:write property= "couName " name= "course "/>
</logic:iterate>
<html:submit> </html:submit>
<html:reset> </html:reset>
</html:form>
</body>
