RE: Custom Table Model.

["Mangavalli, Ramanujam" <RamM@xxxxxxxxxxx>]

Dave,

I was using the ET400 tool in VAJ.

I have not used JTOpen. Do I need to import JTOpen into VAJ and set my class
path? If not, can you please point me in the right direction?

Thanks.

Sure looks like the getRow problem.  Did you try running your test with
JTOpen 3.0?

I am using the AS400JDBCDriver(). The system property is set to an AS400
object. Using the connect() method to obtain the connection.
After the connection is made, here is the code:

Statement SQLStatement =
getJDBCConnectionObject().createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,
ResultSet.CONCUR_READ_ONLY);
ResultSet resultSet =
SQLStatement.executeQuery(getJEditorPane1().getSelectedText());
                                     ResultSetTableModel  ScrollRSModel =
new
ResultSetTableModel(resultSet);

System.out.println(ScrollRSModel.getRowCount());

I see your code contains
   getResultSet().last();
   return getResultSet().getRow();

What JDBC driver are you using?  The Toolbox JDBC driver does not support
getRow() after a cursor movement based on the end of the result set (like
last()) until JTOpen 3.0 / V5R2.
