Dave,
The application works perfectly now. Thank you very much.

Dave,
I imported the JTOpen 3.0 into Eclipse and the getRowCount() now returns the
right number of rows. Now I keep getting the "Cursor State not valid error."

Let me go dig through and see what I am doing wrong now.

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.
