求高手解决!!要实现的是从后台传数据到前台

[hao259296836]

传的是从xml拿到的数据,明明在前台的jsp中用struts:debug看到request中有值saveEle=[org.dom4j.tree.DefaultElement@12088db [Element: <question attributes: [org.dom4j.tree.DefaultAttribute@8420ae [Attribute: name title value "1+1?"], org.dom4j.tree.DefaultAttribute@7db937 [Attribute: name num value "2"]]/>], org.dom4j.tree.DefaultElement@f90137 [Element: <question attributes: [org.dom4j.tree.DefaultAttribute@b049a [Attribute: name title value "1+2?"], org.dom4j.tree.DefaultAttribute@15b28d8 [Attribute: name num value "2"]]/>], org.dom4j.tree.DefaultElement@1bed3d1 [Element: <question attributes: [org.dom4j.tree.DefaultAttribute@1d688e2 [Attribute: name title value "1+3?"], org.dom4j.tree.DefaultAttribute@1b4df9c [Attribute: name num value "2"]]/>], org.dom4j.tree.DefaultElement@1444356 [Element: <question attributes: [org.dom4j.tree.DefaultAttribute@1c4a198 [Attribute: name title value "2+7?"], org.dom4j.tree.DefaultAttribute@4d2b11 [Attribute: name num value "2"]]/>]],但却有异常不能从getAtrribute()拿到对象!后来用测试过对象(==null),竟然是true!!我不知道为何是空的!!求高手解决!!
