Resetting JTables

I'm running out of ideas on this. Basicly I wrote my own console to act as a
more userfriendly interface to interact with an underlyding MySQL database.
Whenever i issue a query i get a pop-up window displaying the results in a
JTable.
My problem is that I would like to reset / re-initialize this JTable so that
the next query I issue, clears the JTable and populates the table with the
news result.
I have tried resetting the model of the table using:

DefaultTableModel model = new DefaultTableModel(data, columnNames);
table.setModel( model );

But that doesnt seem to work, it just displays the result below the results
of the original query.

I add the coloums and rows of the query-result into two seperate vectors.

Any idea?
