to Dear All : i'm beginner in develope,so i have to learn from your. thank for all's help.
i follow the Data binding Sample to use JaveBean in my ZUL page, like is:

<?init class="org.zkoss.zkplus.databind.AnnotateDataBinderInit" ?>

<window >
<zscript><![CDATA[
//prepare the example person object
Person person = new Person();
person.setFirstName("Tom");
person.setLastName("Hanks");
]]>
</zscript>

<grid width="400px">
<rows>
<row> First Name: <textbox value="@{person.firstName}"/></row>
<row> Last Name: <textbox value="@{person.lastName}"/></row>
<row> Full Name: <label value="@{person.fullName}"/></row>
</rows>
</grid>
</window>

But is error, the error information is this:

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

How can i do it? I hava write a JaveBean in my project, the Path is Test.Person.
How can i use the javaBean in zul Page? I want the ZUL page read the data From DataBase and Show it in zul.page,but the first job,i must let the zul Page show the date from JavaBean.
Thank for all!

大家好，英文版的估计还是深夜，我是ZK的初学者，今天有个任务是从数据库中取数据显示到页面，我看了ZK数据绑定的相关教程，也跟着它的例子写了一个，但是在运行时，提示错误，我建立的Person类在页面上无法识别，我想知道ZUL页面中用什么方法才可以引用JAVABEAN啊？ JSP中是用useBean标签的，那ZUL里面呢?
不胜感激！
