HI all experts,

I have a Java Program which shows the List of Ports available in my system.

This program running fine at Command Prompt. But Now i want to use this Java program through PL/SQL.

But i am facing error as attached.

Spend Lot of time But can't Success.

Below is my Java Program.

import javax.comm.*;
import java.util.*;

/** List all the ports available on the local machine. **/
public class TestPorts
public static void main (String args[])

Enumeration port_list = CommPortIdentifier.getPortIdentifiers();

while (port_list.hasMoreElements())
CommPortIdentifier port_id = (CommPortIdentifier)port_list.nextElement();

if (port_id.getPortType() == CommPortIdentifier.PORT_SERIAL)
System.out.println ("Serial port: " + port_id.getName());
else if (port_id.getPortType() == CommPortIdentifier.PORT_PARALLEL)
System.out.println ("Parallel port: " + port_id.getName());
System.out.println ("Other port: " + port_id.getName());
} // main
} // class PortList
