各位老大，struts的一个小问题，但是折磨我三天了，请大家帮忙！
刚入职，要编一个增删查改的功能的页面，用STRUTS。下面是我的STRUTS-CONFIG。
<?xml version= "1.0 " encoding= "UTF-8 "?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN " "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd ">
<struts-config>
<data-sources />
<form-beans>
<form-bean type= "com.dhc.dota.DotaVo " name= "DotaVoForm " />
</form-beans>
<global-exceptions />
<global-forwards />
<action-mappings>
<action path= "/DotaCreate " type= "com.dhc.dota.action.DotaCreateAction " name= "DotaVoForm " parameter= "method " input= " " scope= "session ">
<forward path= "/Sucess.jsp " name= "sucesspage "/>
<forward path= "/Fail.jsp " name= "fail "/>
<forward path= "/DotaCreate.jsp " name= "newpage "/>
</action>
<action path= "/DotaLista " type= "com.dhc.dota.action.DotaListAction " name= "DotaVoForm " parameter= "method " scope= "session ">
<forward path= "/index.jsp " name= "listpage ">
</forward>
</action>
<action path= "/DotaDel " type= "com.dhc.dota.action.DotaDelAction " name= "DotaVoForm " parameter= "method " scope= "session ">
<forward path= "/Sucess.jsp " name= "sucesspage "/>
<forward path= "/Fail.jsp " name= "fail " redirect= "false "/>
</action>
<action path= "/DotaUpd " type= "com.dhc.dota.action.DotaUpdateAction " name= "DotaVoForm " parameter= "method " scope= "session ">
<forward path= "/DotaUpdate.jsp " name= "updatepage "/>
<forward path= "/Sucess " name= "sucesspage "/>
<forward path= "/Fail.jsp " name= "fail "/>
</action>
<action path= "/DotaDetail " type= "com.dhc.dota.action.DotaDetailAction " name= "DotaVoForm " parameter= "method " scope= "session ">
<forward path= "/DotaDetail.jsp " name= "detailpage "/>
<forward path= "/Sucess " name= "sucesspage "/>
<forward path= "/Fail.jsp " name= "fail "/>
</action>
</action-mappings>
<message-resources parameter= "com.dhc.dota.ApplicationResources " />
</struts-config>
在com.dhc.dota.action.DotaListAction中有一个方法，将数据库中的信息存到一个LIST中，下面是代码：
public class DotaListAction extends Action{
public ActionForward listall(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception {
DotaIml iml=new DotaIml();
List list = iml.getlist();
System.out.print( "asdfghhj ");
request.setAttribute( "DotaList ", list);
return mapping.findForward( "listpage ");
}
}
最后是JSP页面index.jsp，代码如下：
<%@ page contentType= "text/html; charset=gb2312 " language= "java " import= "java.sql.* " import= "java.util.* " errorPage= " " %>
<%@ taglib uri= "/WEB-INF/struts-html.tld " prefix= "html "%>
<%@ taglib uri= "/WEB-INF/struts-bean.tld " prefix= "bean "%>
<%@ taglib uri= "/WEB-INF/struts-logic.tld " prefix= "logic "%>
<%@ taglib uri= "/WEB-INF/struts-nested.tld " prefix= "nested "%>
<%@ taglib uri= "/WEB-INF/struts-tiles.tld " prefix= "tiles "%>
<%@taglib uri= "WEB-INF/c.tld " prefix= "c "%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+ ":// "+request.getServerName()+ ": "+request.getServerPort()+path+ "/ ";
%>

<html>
<head>
<base href= " <%=basePath%> ">

</head>
<body>

<form name= "form1 " method= "post " action= " ">
<table align= "center " bgcolor= "#008888 " border= "1 " cellspacing= "2 " cellpadding= "4 ">
<tr bgcolor= "#ccccc ">

<logic:present name= "Dotalist ">
<logic:iterate id= "lio " name= "Dotalist ">

<td> <bean:write name= "lio " property= "sex "/> </td>
<td> <bean:write name= "lio " property= "age "/> </td>

<td> <html:link page= "/DotaDelAction.do " paramId= "id " paramName= "id " paramProperty= "id "> 删除 </html:link> </td>
</tr>
</logic:iterate>
</logic:present>
</table>
<a href= "DotaCreate.do?method=forwardCreate "> <b> <bean:message key= "dota.new " /> </b> </a>
</form>
</body>
</html>
我通过在浏览器中输入：http://localhost:8080/webtest/DotaLista.do?method=listall为什么显示的是一个空白页面的，我保证文件的存放格式都是正确的。谢谢大家，想了三天了！在线等。

你先在action里看看能不能取到list，如果取到了，你就把精力放到页面上，一般的空白页都是页面的问题，如果后台报错，就太好了，在后台解决就可以了
