具有var属性的jsf datatable问题 [英] jsf datatable problem with var attribute

问题描述

在开发带有数据表的小型jsf应用程序时，我遇到了此错误的以下问题

While developing a small jsf application with datatable I am having following problem with this error

The method setVar(String) in the type DataTableTag is not applicable for the arguments (JspValueExpression)

在我的jsp页面中，我有以下代码片段

in my jsp page i have following code fragment

<h:dataTable id="dt1" value="#{dbdata.empno}" var="item" bgcolor="#F1F1F1" border="10" cellpadding="5" cellspacing="3" rows="4" width="50%" dir="LTR" frame="hsides" rules="all" summary="This is a JSF code to create dataTable." >

在我的java文件中，我有以下2个代码片段-

in my java file i have following 2 code fragments--

while (rst.next())
{    
 empno.add(i++,new perInfo(rst.getString(1)));
}

---

public class perInfo {
    String uname;

    public perInfo(String firstName) {
        this.uname = uname;
    }

    public String getUname() {
        return uname;
    }
}

数据库中的数据很好.

我发现"var"属性给了问题

I have found that "var" attribute is giving problem
