You will have to import JTOpen 3.0 into VAJ. VAJ will display errors when
importing because JTOpen 3.0 has support for JDBC 3.0. VAJ will complain
when you import because it won't be able to find classes to resolve
references to the JDBC 3.0 classes.
I have one alternative. You could do something like
// initialize rowCount to be -1
public int getRowCount()
{
if (rowCount < 0)
try
{
getResultSet().beforeFirst();
rowCount = 0;
while (getResultSet().next())
rowCount++;
}
return rowCount;
}
That is, cycle through the rows until you run out, then return the count.
You don't seem to worry about preserving the cursor position in this method
so this should work.
I suggest this only because putting a new version of Toolbox in ET400 can
be painful. VAJ is a great tool, but it is not very flexible. If VAJ
doesn't like something (like missing references) it can be a pain about
letting you move forward. If you do something like the above you should
switch back to doing getRow() when you can easily move up to JTOpen 3.0.

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.
