Java communication api for windows 64 bit

Hi,
I need communication api for windows 64 bit. Are these api's in developement?
Thanks,
Andrea Todeschini

If you use version 2.0 of the rxtx library then it provides a complete implementation of the javax.comm package.
Version 2.1 does not (its in the gnu.io namespace)

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".
kind regards,
Jos

Searching Communications API for Windows

Hello,
I?m looking for the Communications API for Windows XP. At the Downloadcenter I?ll get only a Version named "Generic" - but this doesn?t work with Windows XP.
I think the name off the File have to be "javacomm20-win32.zip"; but I can?t find it. Could anyone help me?

Java(tm) Communication API for win32

I looked all over the java website for the java comm api for windows.... Can't find it... They have it for linux and solaris but no windows.
Is there anywhere on the net that I can get it, if it exists.
The file i'm looking for is javacomm20-win32.zip.
Thanks!

Communication API for Linux

I want to develop an application in Java for Linux that uses serial port .
But java.sun.com provides communications API for Windows, Solaris but not Linux ! ! !
Where can I find free java api to drive a serial port easily ???
Thanks a lot

I think you can do this using the version for Solaris/SPARC along with RXTX for Linux (do a search on google), also I think IBM did a JavaCOMM api for linux.

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.

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.

What deis this message mean? How to make you serial port support work?

and what does this error message mean??
The package was installed accordingly to "Java(tm) Communications API Linux Installation Instructions":
$ls /usr/lib/libLinuxSerialParallel.so
/usr/lib/libLinuxSerialParallel.so
$env|grep CLASS
CLASSPATH=<..skipped..>:/opt/commapi/jar/comm.jar:/opt/commapi/jar/commtest.jar
$ ls /opt/jdk1.5.0_04/jre/lib/javax.comm.properties
/opt/jdk1.5.0_04/jre/lib/javax.comm.properties
What else does it need?

Java accessibility Bridge for windows

I have installed Java Accessibility Bridge for windows but the screen reader in windows (Narrator) is not responding to my java application. On searching the internet, most of them mentioned about JAWS. So is it the only screen reader supporting Java Accessibility Bridge? Also is there any way to use it with Narrator?
Thanks in advance
leeman

Narrator doesn't use the Java Access Bridge so it will not work with Java. Recommend you use another screen reader. Yes, many people do use JAWS, but I also know SuperNova (from Dolphin) and NVDA also work.

Where can i find the Java doc API for Sun Portal 6.2

Hi
I am looking for the java doc api for portal.. for e.g, i want to know the available classes under com.sun.portal.providers.util and method details under that..
Thanks
Ramesh

There should be a file called javadocs.jar in your portal installation directory. Either under SUNWps/sdk or SUNWps/export.

GroupWise API for Windows??

Hi does anyone know where I can download the GroupWise API for Windows if it exists at all?
Currently I am moving my GroupWise system off NetWare and Windows 2003 server, but I am using the GroupWise API 4.1
Thanks.
Steve.

yes Jim that is a good idea, I think may leave a single NetWare 6.5 server running just to be the master and also to the XNTPD service that a lot of my machines run!
One other point is how will the API connect to my GroupWise that will be on another box (or VM machine) ? Does the API only run on UNC or can it run over IP?

You could always put a small VMware machine running NetWare *on* the
Windows box, to handle the API gateway. Would at least eliminate the
need to leave an old piece of hardware up and running just for that.

ITunes COM API for Windows - iTunes 7.7 broken!

I use the iTunes COM API for Windows to control iTunes as part of a program which helps users create audiobooks.
Version 7.7.0.43 of iTunes breaks this software. So far as I can determine, the iTunes.ConvertTracks2 and iTunes.ConvertFiles2 routines are now broken, in that they no longer return a reference to the converted tracks.
Is this a bug on Apple's part, or is it a fundamental change? The COM API documentation describes the earlier behavior, which makes sense.

I'm seeing the exact same behaviour in my application calling the COM API from Perl. No track reference can be obtained after ConvertTracks2 completes.
What's going on?

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.

Java Communications API (JCA) is really that difficult???

Hi everyone, I am an advanced developer for some years in Microsoft Platforms (.NET, VS6, etc.). I have used Microsoft Programs for a while and I can certainly say that I can develop serious programs.
The reason I am posting this is that I am doing some reaserac in the usability of other programmer platforms for windows and linux.
I turned towards Java about a month ago. I kno very well the structure of the language but I came across something very silly:
I tried to install the javax.comm package! Ha ha ha...
I thought SUN is a serious company (one o the largest) and I keep wondering why this package is so difficult to install. I tried every single post on the forums and nothing worked for me. I am using sdk1.4.1
with SUN Studio One update 1 (formerly Forte, ha ha).
IS THERE ANYONE OUT THERE THAT HAS THE API WORKING ON A WINDOWS 2000 PLATFORM (language doesn't matter but the answer -please- must be in english...) THAT CAN GIVE ME THE MAP OF FILES LIKE:
c:\j2sdk1.4.1\bin\win32comm.dl
c:\j2sdk1.4.1\lib\javax.comm.properties
c:\j2sdk1.4.1\lib\ext\javax.comm
c:\program files\java\j2re1.4.1\lib\javax.comm
Classpath = <somthing>
etc.
Please, I can't get this working. I need to see the damn package in the Studio so that I can work properly..
CAN THIS API ORK WITH THE STANDARD EDITION OF JAVA AND THE COMMUNITY EDITION OF FORTE???

Hi,
Acneto, the jar file must be mounted and the
the parser must be updated. If the api is installed
correctly (finally i have it running) then the ide is
able to compile and run programs that are associated
with the api.That's what I've told you before...I've installed the commAPI in windows 98, Me, 2000 and XP...
The problem with installing the API (I haven't told you before because I thought you already done it...) is with the "java home". Lots of people think that their java home is the jdk\lib and may be the c:\windows\java\lib...or other. And other people think that their java home is c:\windows\java\lib and then discover that is \jdk\lib.
So what I always advice is to make a little problem:
class JavaHome
System.out.println("My java home is:"+System.getProperty("java.home"));
}And so copy the files in the wrong place...
(I don't know if there is a different way to update
the parser database without adding the jar to the
filesystem).I don't think so...anyway, you can mount the jar, update the database, and then unmount!
I will make a post today that indicates a way of
installing the api succesfully under win2K pro with
j2sdk1.4.1 and Sun Studio One update 1 IDE.
By the way, I believe that a special forum regarding
serial and parallel port communications should be
launced by SUN. There are just too many ppl out there
that make such applications.I agree with you!
Best regards,
ANeto
