Re: Urgent Help needed to remove row in JTable!

Hi,
really appreciate it! Here's my table model class. It still extends AbstractTableModel since I always got the ArrayOutOfBoundsException when extending DefaultTableModel. (But now I cannot use that removeRow()method)
public class DBTableModel extends AbstractTableModel
{
public static Vector results;
int colCount = 0;
String[] headers;
Connection con = null;
Statement stmt = null;
ResultSet queryResults = null;
public DBTableModel(Connection conn)
{
results = new Vector();
setConnection(conn);
}
public void setConnection(Connection conn) {
con = conn;
}
public String getColumnName(int i) {
return headers;
}
public int getColumnCount() { return colCount; }
public int getRowCount() { return results.size();}
public Object getValueAt(int row, int col)
{
return ((String[])results.elementAt(row))[col];
}
public boolean isCellEditable(int row, int col) {
return true;
}
public void setValueAt(Object value, int row,
int col)
{
((String[])results.elementAt(row))[col] =
value.toString();
fireTableCellUpdated(row, col);
System.out.println("New value @ROW-"+(row+1)
+", COLUMN-"+(col+1)
+": "+((String[])
results.elementAt(row))[col]);
}
public Vector getVector() {
return results;
}
public void setQuery(String q, Connection conn)
{
results = new Vector();
try {
queryResults = ReadDB3.searchQuery(q, con);
ResultSetMetaData meta =
queryResults.getMetaData();
colCount = meta.getColumnCount();
headers = new String[colCount];
for (int h=1; h <= colCount; h++)
headers[h-1] = meta.getColumnName(h);
while (queryResults.next()) {
String[] record = new String[colCount];
for (int i=0; i < colCount; i++) {
record = queryResults.getString(i +
1);
}
results.addElement(record);
}
fireTableChanged(null);
} catch(Exception e) {
results = new Vector();
e.printStackTrace();
}
}
}
