Displaying ResultSet in DataTable component

Question

Say my program codes have created a ResultSet object by applying some SQL query into the database tables.
Now I just want to display the contents of that ResultSet object in the JSC DataTable component. Is it possible? If so, how?
Thank you.

Hi,
I think i have found a way to do what we want to do :
As written in Winston Prakash's Weblog (http://blogs.sun.com/roller/page/winston),
1) I have created a java class "ResultRowDataProvider" that extends ListObjectDataProvider and that contains a method that fill a list from the resultset. (Later, this list will be automatically used to fill the Table Component)
That is to say :
public class ResultRowDataProvider extends ObjectListDataProvider{
private List resultList = new ArrayList();
/** Creates a new instance of ResultRowDataProvider */
public ResultRowDataProvider() {
setUserResizable(true);
public void fillResultList(ResultSet rs){
try{
rs.beforeFirst();
while(rs.next())
resultList.add(new ResultRow(rs.getString(1), rs.getString(2)));
} catch(SQLException sqle){}
setList(resultList);
public int getNbRows(){
return this.resultList.size();
2) I have created a java class "ResultRow" where I defined private attributes that the ResultRowDataProvider will provide.
That is to say :
public class ResultRow(){
private String field1;
private String field2;
public ResultRow(String field1, String field2){
this.field1 = field1;
this.field2 = field2;
public String getField1(){
return this.field1;
public String getField2(){
return this.field2;
public void setField1(String field1){
this.field1 = field1;
public void setField2(String field2){
this.field2 = field2;
3) I finally added the following line to the init( ) method in SessionBean1.java :
resultRowDataProvider = new ResultRowDataProvider();
Then it is compulsory to clean and build the project, to close the project and to reopen it so that the table component layout will take into account the ResultRowDataProvider.
I chose it, but it didn't display the two fields I defined (field1 and field2)
whereas Winston said it should display them. So I defined the table columns myself using as value : #{currentRow.getValue('field1')} for the field1 column.
It worked at runtime.
Now jetsons, I would like to tell you that I personnaly wanted to fill programmatically the Table Component because I am using an Oracle 9.2.0.1 database. In the first version of my project, i used the CachedRowSet. Then I read that i had to use OracleCachedRowSet using ocrs12.jar. But after many bugs at runtime, I had a look to forums and I read that :
"JDBC drivers provided by Oracle are not suitable for Sun Java Studio Creator, and are not supported. Oracle drivers currently available do not fully implement the JDBC 3.0 Specification. Sun Java Studio Creator requires certain schema information at design time that Oracle drivers do not provide."
In fact we can use DataDirect but ...
Filling programmatically a Table Component is a database-independant way ;)
Thank you for your help jetsons and MISS_DUKE.
