ResultSet Issues

Question

I have a servlet that queries a database, puts the data into a 2-D String array, and then forwards this array to a JSP page to display it in a table. The problem is that the table is showing rows 5 through 19 rows (of 19 total rows) and then 4 rows of nulls. I'm guessing that when I am entering the data into the array, I am starting at the fifth row in the ResultSet although I don't know why.
Here are two portions of the Servlet code:
               Statement stmt = con.createStatement(
                    ResultSet.TYPE_SCROLL_INSENSITIVE,
                 ResultSet.CONCUR_READ_ONLY);
               ResultSet rs = stmt.executeQuery(query);
               rows = -1;
               if (rs.last())
                    rows = rs.getRow();
                    rs.first();
// not at first row here for some reason??
               int columns = 6;
               data = new String[rows][columns];
               for(int i = 0; i < rows; i++)
                    data[0] = rs.getString("REDEEM_STATUS");
                    data[i][1] = "folio name";
                    data[i][2] = "checkout";
                    data[i][3] = rs.getString("RDM_CERTNO");
                    data[i][4] = rs.getString("RDM_NUM_OF_NTS");
                    data[i][5] = rs.getString("AMOUNT");
                    rs.next();
          String [][] table = getTable(approve, property);
          request.setAttribute("TABLE", table);
          request.setAttribute("ROWS", new Integer(rows));
          ServletContext context = getServletContext();
          RequestDispatcher dispatcher = context.getRequestDispatcher("/output.jsp");
          dispatcher.forward(request, response);
This is part of the JSP code:
<%
String output[][] = (String[][])request.getAttribute("TABLE");
Integer rows = (Integer)request.getAttribute("ROWS");
int columns = 6;
for(int i = 0; i < rows.intValue(); i++ )
%>
<TR><TD><FORM ACTION="com.Select">
<INPUT TYPE=SUBMIT NAME="button" VALUE="Select">
</FORM></TD>
<%
for(int j = 0; j < columns; j++ )
     s = output[i][j];
%>
<TD><%= s %></TD>
<%
%>
</TR>
<%
%>

You use a sort of non-traditional method of reading the result set, which probably requires the database driver to traverse it twice instead of once. What's wrong with the traditional way?ResultSet rs = stmt.executeQuery(query);
rows = 0;
while (rs.next()) {
  data[rows][0] = ...
  // and so on
  rows ++;
}That's unlikely to be the source of your stated problem, but who knows? You are complaining about the contents of the String[][] named "table", correct? And it's generated by some code you didn't post that doesn't take that "data" array as a parameter. It's quite possible that the problem is there.
