我想从数据库中获取employee name对应的 an employee code，使用vxml. 在浏览器中运行时出现以下错误。
此页面包含以下错误：
第 3 行第 2 列的错误：StartTag：无效元素名称
下面是第一个错误之前的页面渲染。

Connection connection = DriverManager.getConnection(
"jdbc:odbc:data", "userName", "password");
Statement statement = connection.createStatement();
String id = request.getParameter("employee");
ResultSet resultset =
statement.executeQuery("SELECT Ename from Database where Ecode=' "
+ req.getParameter("Employee") + "'") ;
if(!resultset.next()) {
out.println("<prompt cond=\"lang=='2'\">Sorry, No employee of such employee code.Please try again </prompt>
<prompt xml:lang=\"hi-IN\" cond=\"lang=='1'\">क्षमा करे, इश्स तरह के करंचारी कोड का कोई करंचारी यहा काम नही करता </prompt>" +

}

<assign name="user_name" expr="'<%= resultset.getString(1) %>'"/>
<prompt> <value expr= "user_name"/> </prompt>

</form>
</vxml>
