Perform update directly on a data table

Question

Hi,
I'm a totally newbie with Sun Java Creator.
I have follow the tutorial "Performing Inserts, Updates, and Deletes" and my web application work perfectly.
But now I would update my data (stored in a MySQL DB) directly on a data table.
I have drag and drop a data table, bind it and I have set all the column to "Input text (editable)". Then I create another column filled with buttons, the buttons have this code:
try
lineRowSet.setObject(1,(String) getValue("#{currentRow['LILINCOD']}"));
lineRowSet.execute();
lineRowSet.next();
lineRowSet.updateRow();
lineRowSet.commit();
catch (Exception e)
throw new FacesException(e);
But when I press the button I have this error:
Exception Details: javax.faces.FacesException
#{LinesFast.commit_action}: javax.faces.el.EvaluationException: javax.faces.FacesException: java.sql.SQLException: No parameters defined during prepareCall()
Can anyone help me please?
Thanx a lot.

Hi,
All the three rowsets that you see in the OnePage.jsp in AppModel are not bound to the datatable. One rowset is bound to the dropdown list to display the names of persons (personRowSet), second rowset is bound to the outputText to display the JobTitle of the selected person in the dropdown(personRowSet1) and the third rowset is bound to the datatable to display the trip details (tripRowSet).
Also when you are using the datatable which is bound to a rowset you can make use of dataTableModel to do the database table transactions as you can see in the AppModel example. If you will go through the code you will notice the dataTableModel1.execute(). So the AppModel is not complicated as it might appear.
Please do go through the sample application once again as it exactly demonstrates what you want to achieve.
Hope that helps
Cheers
