Installing libraries

Question

Hi,
I would like to install the java communications library in Jbuilder. It has three files:
win32com.dll
comm.jar
javax.comm.properties
I went to tools->configure->libraries, then clicked on new and added the folder where all these files are. I could only select the .jar file under classes. I don't know if I Jbuilder picks up on the other two automatically. When I ran the SimpleWrite.java program that came with the library, it says that the port could not be opened.
Here is the simple write program:
public class SimpleWrite {
static Enumeration     portList;
static CommPortIdentifier portId;
static String     messageString = "Hello, world!";
static SerialPort     serialPort;
static OutputStream outputStream;
static boolean     outputBufferEmptyFlag = false;
* Method declaration
* @param args
* @see
public static void main(String[] args) {
     boolean portFound = false;
     String defaultPort = "/dev/term/a";
     if (args.length > 0) {
     defaultPort = args[0];
     portList = CommPortIdentifier.getPortIdentifiers();
     while (portList.hasMoreElements()) {
     portId = (CommPortIdentifier) portList.nextElement();
     if (portId.getPortType() == CommPortIdentifier.PORT_SERIAL) {
          if (portId.getName().equals(defaultPort)) {
          System.out.println("Found port " + defaultPort);
          portFound = true;
          try {
               serialPort =
               (SerialPort) portId.open("SimpleWrite", 2000);
          } catch (PortInUseException e) {
               System.out.println("Port in use.");
               continue;
          try {
               outputStream = serialPort.getOutputStream();
          } catch (IOException e) {}
          try {
               serialPort.setSerialPortParams(9600,
                              SerialPort.DATABITS_8,
                              SerialPort.STOPBITS_1,
                              SerialPort.PARITY_NONE);
          } catch (UnsupportedCommOperationException e) {}
          try {
               serialPort.notifyOnOutputEmpty(true);
          } catch (Exception e) {
               System.out.println("Error setting event notification");
               System.out.println(e.toString());
               System.exit(-1);
          System.out.println(
               "Writing \""+messageString+"\" to "
               +serialPort.getName());
          try {
               outputStream.write(messageString.getBytes());
          } catch (IOException e) {}
          try {
          Thread.sleep(2000); // Be sure data is xferred before closing
          } catch (Exception e) {}
          serialPort.close();
          System.exit(1);
     if (!portFound) {
     System.out.println("port " + defaultPort + " not found.");
If anyone is familiar with Jbuilder setting, please help. Thanks in advance.
