To access persistence objects in ZUML page is simple, simply declare a persistence object, and uses it to get data from database.
- Create a
event.zulin the root directory of web development. (ex.$myApp/event.zul)
<zk>
<zscript><![CDATA[
import java.util.Date;
import java.text.SimpleDateFormat;
import events.Event;
import events.EventDAO;
//fetch all allEvents from database
List allEvents = new EventDAO().findAll();
]]></zscript>
<listbox id="lbxEvents">
<listhead>
<listheader label="Title" width="200px"/>
<listheader label="Date" width="100px"/>
</listhead>
<listitem forEach="${allEvents}" value="${each}">
<listcell label="${each.title}"/>
<zscript>String datestr = new SimpleDateFormat("yyyy/MM/dd").format(each.date);</zscript>
<listcell label="${datestr}"/>
</listitem>
</listbox>
</zk>
- Open a browser and visit the ZUML page. (ex.
http://localhost:8080/event/event.zul)
