pst.setString(1,visit_combo.getSelectedItem().toString());
ResultSet rs =pst.executeQuery();
while(rs.next())
{
vno= rs.getString(1);
vnam=rs.getString(2);
vtp=rs.getString(3);
pur=rs.getString(4);
in=rs.getString(5);
dat=rs.getString(6);
String s[]={vno,vnam,vtp,pur,in,dat};
Vector coldata=new Vector(Arrays.asList(s));
rowdata.add(coldata);
}
String[] head={"VISITOR NO","VISITOR NAME","VISIT TO PERSON","PURPOSE","IN TIME","DATE"};
colname=new Vector(Arrays.asList(head));
tableModel =new DefaultTableModel(rowdata, colname);
table = new JTable(tableModel);
table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
JTableHeader header = table.getTableHeader();
JScrollPane pane = new JScrollPane(table);
pane.setAutoscrolls(true);
pane.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS);
pane.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);
pane.setSize(450,300);
