GetHardwareAddress() and JSP. Plz help

Question

I'm writing a JSP page that must get The MAC Address of the client.
I used the following code:
InetAddress addresses = InetAddress.getByName("192.168.1.100");
NetworkInterface ni = NetworkInterface.getByInetAddress(addresses);
byte[] mac = ni.getHardwareAddress();
if (mac != null) {
for (int i = 0; i < mac.length; i++)
outz.write(mac);
outz.write puts the result in an HTML page
the result i got was: !k&?" instead of the typical xx-xx-xx-xx-xx
I figured out that maybe the result isnt being written in hex so I added:
{code}{code}
InetAddress addresses = InetAddress.getByName("192.168.1.100");
NetworkInterface ni = NetworkInterface.getByInetAddress(addresses);
byte[] mac = ni.getHardwareAddress();
if (mac != null) {
for (int i = 0; i < mac.length; i++)
outz.write("%02X%s", mac[i], (i < mac.length - 1) ? "-" : "");
the error I got was:
An error occurred at line: 19 in the jsp file: /jsp/savename.jsp
The method format(String, byte, String) is undefined for the type FileWriter
16: byte[] mac = ni.getHardwareAddress();
17: if (mac != null) {
18: for (int i = 0; i < mac.length; i++) {
19: outz.write("%02X%s", mac[i], (i < mac.length - 1) ? "-" : "");
20: }
21: }
22:
VERY IMPORTANT NOTE: this code works in normal java file, but in JSP it makes this error.
Plz can anyone help me figure what's the error? and how to solve it?
can anyone provide a working way for this, using these methods? and thx very much.

Answer 1

look bidox this is the query
String sql= "SELECT * FROM WOH.P_DEMGRAPHICS " +
"WHERE P_ID LIKE \'%" + query+ "%\'";
and P_DEMGRAPHICS is tabel inside my WOH database
and am searching using the Primary key
i uploaded screen shot to understand
http://rapidshare.com/files/102091314/tabel.JPG.html
i want to retrive raws using P_ID ie input P1 and it will return the rows
Now it should work! what you doing wrong is the database just use the table ignoring the WOH; the reason is, if you logged in the workspace using your username and password, automatically oracle will recordnise the table with that user login assigned.
Your code now looks like this;
String sql= "SELECT * FROM P_DEMGRAPHICS " +
"WHERE P_ID LIKE \'%" + query+ "%\'";
