Hi everybody,
I'm trying to write a Java Stored Procedure in Oracle 8.1.7, to be used inside a trigger, sendind a notification message via UDP broadcast.
It seems to me that there is no way to grant a permission (SocketPermission), so that the message can be sent (all the available permissions are liste,resolve,accept,connect).
This is the code of the Java class I would like to use:
-------------------------------------------
import java.lang.*;
import java.io.*;
import java.net.*;
import java.util.*;
public class UdpSendMessage {
public static void UDPBroadcast(String hostname, String strport, String message) throws IOException {
DatagramSocket socket = new DatagramSocket();
String str = message;
byte[[]] buf = new byte[[256]];
buf = str.getBytes();
int port = Integer.parseInt(strport);
InetAddress address = InetAddress.getByName(hostname);
DatagramPacket packet = new DatagramPacket(buf, buf.length, address, port);
// HERE THE ERROR!!!
socket.send(packet);
socket.close();
System.out.println("Sent: '" + str + "' sent to host '" + address.getHostName() + ":" + port + "'");
}
}
-------------------------------------------
all works fine as long as the "socket.send(packet)" is commented out (which makes the procedure useless); otherwise I have:
ORA-29532: chiamata Java terminata a causa di un'eccezione Java non ottenuta:
java.net.SocketException: sendto failed, errno = 10013
An attempt was made to access a socket in a way forbidden by its access
permissions.
ORA-06512: a "TEST.UDPSENDMESSAGE", line 0
ORA-06512: a line 1
Can anyone please help me?
TIA.

first try to compile and execute ur code as java standalone.
then
1. Logon as SYS
2. issue the following commands :
call dbms_java.grant_permission('user','java.net.SocketPermission','*','connect,resolve');
commit; --****MUST****
call dbms_java.grant_permission('user','java.util.PropertyPermission','*','read,write');
commit; --****MUST****
3. try to compile/execute ur java stored procedure
