Question: about data binding

Question

hi :
I want to know components binding database in UIX . for example :
Component -- "train" , now , I only get data souce from javaBean ,but the data is static . of course , i know this only .I want to know train how to binding database ,
get value from database.
i study uix Shortly , please help me . thanks , in advance . It's better provide a example . Thanks , again.
Follows is via javaBean, code, like this .
datapage.uix
<dataScope xmlns="http://xmlns.oracle.com/uix/ui">
<provider>
<data name="nodeData">
<method class="view.NodeBean" method="getTableData"/>
</data>
</provider>
<contents>
<train value="${bindings.StepSno}">
<contents childData="${uix.data.nodeData}">
<link text="${uix.current.text}"/>
</contents>
</train>
</contents>
NodeBean.java (javaBean)
static public Object getTableData(RenderingContext context, String namespace, String
name)
// The following List is recreated every time this method is called
// (which is once per page render). A better implementation would
// move the List creation to a UIX Servlet Event Handler.
// See the Using a Controller in ADF UIX chapter for more information.
List list = new ArrayList();
for (int i = 0; i < 5; i++)
HashMap row = new HashMap();
row.put("text", "Row " + i);
list.add(row);
return list;
for this example , i can get data from javaBean as train's value , but the data is
static , i want to get data from database , but i don't know how to do this . please help me
thanks very much ,again , in advance .

Hi,
<train value="${bindings.StepSno}">
uses Expression Language to bind to the ADf binding object. You can add your own Java bean that accesses the database and reference it in the same way.
