Identifying a comm port using java communication API

HI ALL,
i'm using the communication API to detect the comm port to which my modem is attached.
i say CommPortIdentifier c = CommPortIdentifier.getPortIdentifier("COM3");
then i SOP(c.getName())
i get an exception saying noSuchPortException
i've put the javax.comm.properties file in jdk/lib but to no avail.
i also have a win32com.dll file that is there inside lib.
but this hasn't helped. Now the properties file has a driver mentioned. do i have 2 download that driver or does it come with the OS (i've no idea)
i would be helpful if anybody could help me out with this problem.

Try putting tha javax.comm.properties file in you <java>/jre/lib folder as well... It worked for me !

Problem in sending SMS via using java communication API

I need to send SMS via my sony ericsson Z530i. It is connected to the com5 port of my system. I got the following code.

E:\java\JavaSmsApi>javac SerialToGsm.java
E:\java\JavaSmsApi>java SerialToGsm
Exception in thread "main" java.lang.NoSuchMethodError: main
What might be the error? Somebody help me. Thanks in advance.

You are probably trying to run this as a CLDC application instead of a MIDP application (aka a MIDLet). Since CLDC apps start with a main(....) your runtime looks for one but does not find it, hence the error. Please recheck the project configuration.

Java Communications API

Hi
I've written a program to communicate with a circuit with JCA throught LPT Port. I have done this:
import java.io.*;
import java.util.*;
import javax.comm.*;
public class test65{
static Enumeration portList;
static CommPortIdentifier portId;
static int num = 8;
static ParallelPort parPort;
static OutputStream outputStream;
public static void main(String arg[]){
portList = CommPortIdentifier.getPortIdentifiers();
while (portList.hasMoreElements()) {
portId = (CommPortIdentifier) portList.nextElement();
if (portId.getPortType() == CommPortIdentifier.PORT_PARALLEL) {
System.out.println ("Found Parralel Port :"+portId.getName());
if (portId.getName().equals("LPT1")) {
try {
parPort = (ParallelPort)portId.open("Robotics", 2000);
} catch (PortInUseException e) {
System.out.println("ERROR: This port is in use by: "+e.currentOwner+".");
try {
outputStream = parPort.getOutputStream();
} catch (IOException e) {
System.out.println ("ERROR: IO Exception.");
parPort.close();
} catch (NullPointerException e){
System.out.println ("ERROR: OutPutStream could not be Created.");
parPort.close();
try {
System.out.println ("Number "+num+" is about to be sent ....");
System.out.println ("Mode : "+parPort.getMode());
outputStream.write(num); //(1)
System.out.println ("Number "+num+" was Sent.");
} catch (IOException e) {
System.out.println ("ERROR: Could not Write Output");
parPort.close();
in the line that writes num to the stream,(1), program stops and doesn't send anything. If i install a printer then the num is sent to the printer driver to be PRINTED. i don't want to print anything. I've think if there is any driver that sends to the port whatever it recieves. What should i do to send numbers to LPT port like outp and out commands in basic and c ?

When using java communications api you need to simulate a centronics printer circuit in order to get output to the pins all this requires is that you pull pin11 (Busy) low, pin12 (Paper Out) low, and pin15 (Printer Error) High, although I've only had success thus far using spp mode which of course only supports output. Good luck all.

Problem with Java Communication API

hi
I installed the Java Communication API on win32 platform (as per the guidelines)
Now when I try to run the sample program 'Blackbox' for the serial port, I get an error (in fact an exception is generated inside main function in BlackBox.class file)
I tried the SimpleRead.java example but that too generated the same exception
Can anybody help me out.... I am a novice with Java Comm API

I tried running the sample BlackBox program provided for serial port and now it says
No Serial Ports Found!
I verified that both comm.jar and javax.comm.properties are in the <JDK>\lib directory.
Actually, I am using netBeans IDE 1.4 and I used the C:\J2SDK folder installed with netBeans for the Java Communicaion API
plz help.

About Java Communication API for Windows

hi
I'm studying Serial Communication in university.
I'd like to know the reason why we can't downlaod Java Communication API for Windows.
I confirmed Comm for Linux and Soralis, but I can't find Comm for Win.
Please tell me the reason if someone know.

For no particular reason Sun stopped supporting the windows version
of that package. I use rxtx which happens to allow for much faster
communication too.
The interface is identical to Sun's version, just the package differs: "gnu.io".

How to print a document in reverse order using Java Print API ?

Does Java Print API supports reverse order printing ?

Which method implementation of Pageable interface should return the page number ?w.r.t. your first question: don't return that number but return page n-1-i when page i is requested; your document will be printed in reverse order. Your class should implement the entire interface and wrap the original Pageable. (for that number n your class can consult the wrapped interface; read the API for the Pageable interface).

Using Java Mail API from Tomcat

Hello,
Purely as an academic exercise I have written a JSP page which, upon being requested from the client's browser, should send me a default email using Java Mail Api.
here is the code :
import java.util.*;
import java.io.*;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;
public class TestMail {
    static String msgText1 = "success this time 12";
    static String msgText2 = "This is the text in the message attachment.";
    public String sendIt() {
        String to = "<my email";
        String from = "<anything>";
        String host = "<my ip address of smtp server>";
        boolean debug = false;
        Properties props = new Properties();
        props.put("mail.smtp.host", host);
        Session session = Session.getInstance(props, null);
.....The code works fine as a stand alone app but when called from JSP page it hangs on the Session.getInstance line. I can only guess that this might be a security issue with the container not allowing access to the smtp server ?
Can anyone give me a clue ???

Your Tomcat log files should spell out the problem for you.
My Tomcat installation does not come with the Java Mail API. I had to add the mail and activation jar files to the server/common.lib directory (or the server's shared/lib or the WEB-INF/lib of your application.)
HTH.

Java Communications API and Java SDK 1.4.2

I just installed the Java Communications API 2.0 on my Windows XP system, with JDK 1.4.2. As per the install instructions, I copied files from the zip into my /lib and /bin directories and set the classpath. However, when I attempt to compile any of the samples, the compiler displays a large number of errors. I know the API documentation only references JDK1.2 -- are there any special tricks to installing on newer JDKs, or will I need to acquire an older JDK to develop?

My path variable is still not being set! Here is the content of my autoexec.bat located on the root directory of C:\
rem - By Groove Setup
PATH=%PATH%;"C:\Program Files\Groove Networks\Groove\Bin"
PATH=%PATH%;C:\PROGRAM FILES\J2SDK1.4.2_07\BIN
/code]
When I type 'path' at the MSDOS C:\ prompt, I receive the following in the get the following:C:\WINDOWS;C:\WINDOWS\COMMAND;\C:\PROGRAM FILES\GROOVE NETWORKS\GROOVE\BIN
As an aside, I noticed that when I perform a search of the my hard drive (c:\), I find two autoexec.bat files. One at the root, and the other in C:\Windows\Command\EBD.
I believe the instructions stated to modify the autoexec.bat at the root directory.
TIA for any assistance. This is really becoming a nusance and taking up quite a bit of my time trying to resolve this problem.

> JMX and instrumentation are quite different things.
Not that I know a great deal about either, but this is from the API:
"Provides services that allow Java programming language agents to instrument programs running on the JVM."
And this is from the overview I linked:
"The Java virtual machine (JVM) is instrumented for monitoring and management, providing built-in ("out-of-the-box") management capabilities for for both remote and local access."
That sounds at least superficially similar to me. I'll do more research when I have the time/need. Thanks for pointing it out, though.

Can anyone please tell me what is the problem. I thought that we cannot directly
do
InitialContext ic = new InitialContext();
So I had written a method getInitialContext() as shown in the above piece of code,
but that too did not work.
Eagerly awaiting a response.

You can use InitialContext ic = new InitialContext() only if you are using a startup class, servlet or a JSP i.e
server side code.
If you are using a java client you need to use Context ic = getInitialContext();
Try this code
import java.util.*;
import javax.activation.*;
import javax.mail.*;
import javax.mail.internet.*;
import javax.naming.*;
import java.io.*;
import java.net.InetAddress;
import java.util.Properties;
import java.util.Date;
public class MailTo {
public static void main(String args[])
try {
Properties h = new Properties();
h.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");
h.put(Context.PROVIDER_URL, "t3://localhost:7001");
Context ic = new InitialContext(h);
Session session = (Session) ic.lookup("testSession");
Properties props = new Properties();
props.put("mail.transport.protocol", "smtp");
props.put("mail.smtp.host", "XX.XX.XX.XX");
props.put("mail.from", "[email protected]");
Session session2 = session.getInstance(props);
Message msg = new MimeMessage(session2);
msg.setFrom();
msg.setRecipients(Message.RecipientType.TO,InternetAddress.parse("[email protected]",false));
msg.setSubject("Test Message");
msg.setSentDate(new Date());
MimeBodyPart mbp = new MimeBodyPart();
mbp.setText("This is a mail sent to you using JAVA Mail API and Weblogic Server");
Multipart mp = new MimeMultipart();
mp.addBodyPart(mbp);

Hi All,
I am trying to use the Java Mail API provided by WLS 7.0. I have made the
settings metioned in the WLS 7.0 docs. However when I try to run the program I
am getting the following error:
javax.naming.NoInitialContextException: Need to specify class name in environment
or system property, or as an applet parameter, or in an application resource file:

a:283)
at javax.naming.InitialContext.lookup(InitialContext.java:350)
The code that I have written is as follows
import java.util.*;
import javax.activation.*;
import javax.mail.*;
import javax.mail.internet.*;
import javax.naming.*;
import java.io.*;
import java.net.InetAddress;
import java.util.Properties;
import java.util.Date;
public class MailTo {
public static void main(String args[])
try
//Context ic = getInitialContext();
InitialContext ic = new InitialContext();
/* My jndi name is "testSession" */
Session session = (Session) ic.lookup("testSession"); /* THE PROBLEM IS SHOWN
IN THIS LINE */
Properties props = new Properties();
props.put("mail.transport.protocol", "smtp");
props.put("mail.smtp.host", "XX.XX.XX.XX");
/* For security reasons I have written the ip add in this format */
props.put("mail.from", "[email protected]"); /* for security reasons i have
changed the mail address */
Session session2 = session.getInstance(props);
Message msg = new MimeMessage(session2);
msg.setFrom();
msg.setRecipients(Message.RecipientType.TO, InternetAddress.parse("[email protected]",
false));
msg.setSubject("Test Message");
msg.setSentDate(new Date());
MimeBodyPart mbp = new MimeBodyPart();
mbp.setText("This is a mail sent to you using JAVA Mail API and Weblogic Server");
Multipart mp = new MimeMultipart();
mp.addBodyPart(mbp);
msg.setContent(mp);
Transport.send(msg);
catch(Exception e)
e.printStackTrace();
}//end of main
public static Context getInitialContext()
throws NamingException
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
p.put(Context.PROVIDER_URL, "t3://localhost:7501/testWebApp");
p.put(Context.SECURITY_PRINCIPAL, "weblogic");
p.put(Context.SECURITY_CREDENTIALS, "weblogic");
return new InitialContext(p);
}//end of class
Can anyone please tell me what is the problem. I thought that we cannot directly
do
InitialContext ic = new InitialContext();
So I had written a method getInitialContext() as shown in the above piece of code,
but that too did not work.
Eagerly awaiting a response.

public class MailSender {
     public String sendMessage(){
        String msg ="Hello mail Test";
        String smtpServer ="mySMTPServer";
        String smtpSender = "senderemailaddress";
        String smtpRecipient="receipientemailaddress";
        String stBody = msg ;
        //String stDate = new Date().toString() ;
        String stSubject = "Mail Test ";
        Send(     smtpServer,          //SMTPServer
                  smtpSender,          //Sender
                  smtpRecipient,     //Recipient
                  stSubject,          //Subject
                  stBody               //Body
                    );               //Attachments
     return "Mail Success";
public static void Send(String SMTPServer,
                              String From,
                              String To,
                              String Subject,
                              String msgText1
        // Error status;
        int ErrorStatus = 0;
        // create some properties and get the default Session
        Properties props = System.getProperties();
        props.put("mail.smtp.host", SMTPServer);
        Session session = Session.getDefaultInstance(props, null);
        try {
             // create a message
             MimeMessage msg = new MimeMessage(session);
             msg.setFrom(new InternetAddress(From));
             InternetAddress[] address = {new InternetAddress(To)};
             msg.setRecipients(Message.RecipientType.TO, address);
             msg.setSubject(Subject);
             // create and fill the first message part
             MimeBodyPart mbp1 = new MimeBodyPart();
             mbp1.setText(msgText1);
             // create the Multipart and its parts to it
             Multipart mp = new MimeMultipart();
             mp.addBodyPart(mbp1);
             //mp.addBodyPart(mbp2);
             // add the Multipart to the message
             msg.setContent(mp);
             // set the Date: header
             msg.setSentDate(new Date());
             // send the message
             Transport.send(msg);
        } catch (MessagingException mex) {
Call this file from the JSP page (which is set at JSPDynPage controller)
one important thing-----
Create a dir under PORTAL-INF and import the following jars-- activation.jar, mail.jar,imap.jar,smtp.jar, mailapi.jar.
This works..
Thanks once again to the Experts.
happy mailing
