JTable in not visible

here is a piece odf code....
it creates and returns an instance of JTable.
the query if perfect.

public static JTable getResult(String query)
    {
        JTable t=null;
        ABCModel abcmodel=new ABCModel();
        Vector data=new Vector();
        Vector cNames=new Vector();

        int i=1;
        int cNum=0;
        try
        {
            res= stmt.executeQuery(query);
            rem=res.getMetaData();
            cNum = rem.getColumnCount();

            for(;i<=cNum;i++)
            {
                cNames.addElement(rem.getColumnName(i));
            }

            while(res.next())
            {
                Vector rowdata=new Vector();
                for(i=1;i<=cNum;i++)
                {
                    rowdata.addElement(res.getObject(i));
                }
                data.addElement(rowdata);
            }
            t=new JTable(data,cNames);
        }
        catch(SQLException se){new SQLExceptionGUI(se).printMessage();}
        finally {}
        return t;
    }

but it is not displaying table on frame.

plz suggest any change...
thanks
