I have written about this topic in my blog(http://farmerinchina.blog.sohu.com/46978657.html), and now paste here for some discussion.

In some situation, people need to create tables at runtime, so it is hard to map the table to pojo. In my project, I just need to display the content of new table, and then I use the following solution. But I think it has more meaning than what past here.

<t:dataTable id="recorddata"
<t:columns value="#{tableBean.headerModel}" var="columnHeader">
<f:facet name="header">
<h:outputText value="#{columnHeader.cname}" />
<h:outputText value="#{tableBean.columnValue}" />

Backing Bean:

public class TableBean{

private DataModel recordModel;
private DataModel headerModel;
private int labelIndex = 0;

public DataModel getHeaderModel()
if(headerModel == null)
headerModel =new ListDataModel();
return headerModel;

public DataModel getRecordModel() {
if(recordModel== null)
recordModel=new ListDataModel();
return recordModel;

public String getColumnValue()
if(recordModel == null) recordModel = getRecordModel();
Map map = (Map)recordModel.getRowData();
List list = getColumnHeaderList();
String key = list.get(labelIndex)).toString();
Object o = map.get(key);
if(o == null) o = "";
if(labelIndex == map.size()) labelIndex = 0;
return o.toString();
return null;


public class TableDAO{

/*******Get the content of dynamic created table******/
public List getRecordList(String tablename)
SQLQuery query = session.createSQLQuery("select * from "+tablename);
List list = query.setResultTransformer(Criteria.ALIAS_TO_ENTITY_MAP)
.list();//transform resultset to map
return list;
/*******Get column header**********/
public List getRecordHeaderList()


I use hibernate-3.2, and myfaces-1.1.5
