TYPE_SCROLL_INSENSITIVE Error

Question

Hey guys
I've got a problem, which I can't seem to figure out.
I'm trying to fill a JTable with data. I've written two methodes to do so, one to get the rowdata and one to get the columnames.
Here's an example of one of them.
public Object[][] haalGegevensOp(String SQL) {
Object mijnArray[][] = null;
ResultSet rs;
try {
Statement stmt = con.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY);
rs = stmt.executeQuery(SQL);
rs.last();
int arij = rs.getRow();
rs.beforeFirst();
ResultSetMetaData rsmd = rs.getMetaData();
int akol = rsmd.getColumnCount();
mijnArray = new Object[arij][akol];
int r = 0;
while (rs.next()) {
for (int c = 1; c <= akol; c++) {
mijnArray[r][c - 1] = rs.getObject(c);
//System.out.print(mijnArray[r][c - 1] + " ");
r++;
System.out.println();
rs.close();
return mijnArray;
} catch (Exception e) {
System.out.println("De gegevens kunnen niet opgehaald worden");
e.printStackTrace();
return null;
The program gives an error on the line in bold.
The only feedback i get is "java.sql.SQLException: General error"
Before you say anything, the SQL statement I use is a valid one, but it will only work when the ResultsetType = TYPE_FORWARD_ONLY.
How can I fix this?

You're probably using a non-serious JDBC driver. You could code to not need to know how
many rows there are, just collecting until done, then making your array...
