Error while opening port in Java
- by Deepak
I am getting the following error while trying to open the cash drawer.
Error loading win32com: java.lang.UnsatisfiedLinkError: C:\Program Files\Java\jdk1.6.0_15\jre\bin\win32com.dll: Can't load IA 32-bit .dll on a AMD 64-bit platform
The code i am using is as follows
`import javax.comm.;
import java.util.;
/** Check each port to see if it is open. **/
public class openPort {
public static void main (String [] args) {
Enumeration port_list = CommPortIdentifier.getPortIdentifiers ();
while (port_list.hasMoreElements ()) {
// Get the list of ports
CommPortIdentifier port_id =
(CommPortIdentifier) port_list.nextElement ();
// Find each ports type and name
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 ());
} else
System.out.println ("Other port: " + port_id.getName ());
// Attempt to open it
try {
CommPort port = port_id.open ("PortListOpen",20);
System.out.println (" Opened successfully");
port.close ();
}
catch (PortInUseException pe)
{
System.out.println (" Open failed");
String owner_name = port_id.getCurrentOwner ();
if (owner_name == null)
System.out.println (" Port Owned by unidentified app");
else
// The owner name not returned correctly unless it is
// a Java program.
System.out.println (" " + owner_name);
}
}
} //main
} // PortListOpen`
