How to use java comm API in 64 bit javn on solaris 10

hi,
I want to connect to a device through serial port on sparc Solaris 10 in 64-Bit JVM, but i cannot find the correct API for that, i have tried using RXTX but it has many issues.
I noticed SUNWjcomx package is removed in Solaris 10.

How to use the COMM API in a JAR file

I have developed an application, using the NetBeans IDE, to communicate with a modem over the COM1 serial port using the Java Comm API. The application works fine within the IDE, but when a JAR file is created and "double-clicked", the application launches correctly, but when the code is executed to "talk" over the COM1 serial port - nothing happens. No exceptions and no warnings are thrown. My environment is XP, SP1.
The manifest file is as follows:
Manifest-Version: 1.0
Class-Path: ../j2sdk1.4.2/jre/lib/ext/TimerBean.jar ../j2sdk1.4.2/jre/
lib/ext/AbsoluteLayout.jar ../j2sdk1.4.2/jre/lib/ext/comm.jar
Created-By: NetBeans IDE
Specified-By: Projects/TheApp/Files/TheApp.jarContent
Main-Class: Main
According to the Comm API installation instructions, the following files are copied:
copy comm.jar \j2sdk1.4.2\jre\lib\ext
copy wind32com.dll \j2sdk1.4.2\bin
copy javax.comm.properties \j2sdk1.4.2\jre\lib
I suspect it has something to do with the paths.
Any help would be greatly appreciated. Thanks.

Thanks for your input, but after trying what you suggested the problem still exists. I think your right to be suspicous of the javax.comm.properties file. The application, that worked in the IDE, exhibits the same behavoir as the JAR file if the javax.comm.properties file is removed from the ../jre/lib directory. In other words it compiles correctly in the IDE, but when executed, nothing happens when the code that "talks" to the serial port is run.
I've tried moving the javax.comm.properties file into the working directory. Also, the CLASSPATH and PATH system variables were modified to include the path to javax.comm.properties.
If you have anymore ideas, please let me know.
Thanks.

HOW TO USE JAVA OWB API

I'm sorry for my English.
I try to use java owb api to execute process flow of my owb project from my web application. I use oracle 11g.
I have found only this thread about use of owb api (https://kr.forums.oracle.com/forums/thread.jspa?threadID=248256&tstart=0).
I can establish a connection, obtain the project, process flow or mapping object but i can't understand how to run it.
Help me please
Stefano

> 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.

Problem in Accessing serial port using java comm Api

I have installed java comm Api in my pc.
i have gone through the instalation instruction which comes on this package.
I have done the instalation like this
Copy win32com.dll to my <JDK>\bin directory.
Copy comm.jar to my <JDK>\lib directory.
Copy javax.comm.properties to my <JDK>\lib directory.
and restart the system.
But when i run the BlackBox , it is giving me message
"serial port not found".
Can any one tell me , what is the exact problem ?

I'm not sure what you mean by BlackBox, but I have used the COMM api extensively.
The majority of problems is that the api cannot see the serial port (which is what you are describing) and this is caused by incorrect placing of the javax.comm.properties file.
As well as <JDK>\lib, try putting it into <JRE>\lib as well. That has often solved problems on my setup.

How to use Java Mail API in Unix

I am trying to write some code using Java mail API. I want to execute it in Unix. I downloaded the mail API to windows machine and ftped the mail.jar file to a Unix machine. Then I set the class path as below:
export CLASSPATH=$CLASSPATH:/home.../mail.jar
Then I tried to compile my Java program. The output is as below:
error: error reading /home.../mail.jar; invalid END header (bad central directory offset)
mail.java:1: package javax.mail does not exist
import javax.mail.*;
Can any one please help me out.

You should also include the "activation.jar" file that you obtained from
downloading the Java Activation Framework, in your CLASSPATH.
For example:
export CLASSPATH=$CLASSPATH:/urPath/activation/activation.jar
Besides, assuming you unzipped javamail-1_4_1.zip in home/download the following should work
export CLASSPATH=$CLASSPATH:home/download/javamail-1.4.1/mail.jar:.

Java comm api in 64-bit Linux

I apologise if this is off-topic. I can't find a suitable forum, I tried posting in the Java plugin forum, but no luck there. I would appreciate any ideas to find a solution.
I am trying to use the java comm api to read and write to the serial port but I am getting the following error:
Error loading LinuxSerialParallel: java.lang.UnsatisfiedLinkError: /usr/lib64/libLinuxSerialParallel.so: Can't load IA 32-bit .so on a AMD 64-bit platform
I am using openSUSE 10.2 (X86-64) which uses Linux 2.6.18.2-34-default x86_64.
I tried Switching to a 32-bit version of java (1.4.2) from within Eclipse and I always run Eclipse in 32-bit java (/usr/share/eclipse/eclipse -vm /usr/lib/jvm/java-1.4.2-gcj-1.4.2.0/jre/bin/java) but I still get this error.
Is there anything I can do to get the java comm api working on a 64-bit system?
Is the java comm api still being developed and maintained? It does not look like it is?
I've done some searching on the web and I find there is an open source version of the java comm api called RXTX but the website at http://www.rxtx.org/ is not very readable. I don't think I know enough to install this on my system.
I would appreciate any ideas to get this working.
Thanks,
Martin

I'm stuck again so I would appreciate some more help.
I've managed to install the Sun 1.6 JDK and configure
and make rxtx.Any small amount of progress is still progress. :)
>
But it still does not work, I get the following error
when I run the SerialDemo:<snip>
>
It seems to be com.sun.comm which is not finding its
native binary not rxtx! No, it's finding the shared library, unless there are a few more lines at the start of your error message that look like this:
Error loading LinuxSerialParallel: java.lang.UnsatisfiedLinkError:
no LinuxSerialParallel in java.library.pathIt's not finding the function it is looking for in that library.
This is what confuses me, the
instructions say install the Solaris version of comm
api (http://www.rxtx.org/ how-to said Solaris Sparc
and the rxtx INSTALL file said Solaris x86 so I tried
both in turn and neither worked) Same here after downloading the latest stuff to my x86 Linux box. I received a similar UnsatisfiedLinkError. I checked the shared libraries and the functions were not in it.
normally these would
call the Solaris binary drivers but I assume this has
to be redirected to rxtx which calls its own
binaries?Yes. There is a part of RXTX called JCL (Java Comm for Linux) that handles that.
http://www.geeksville.com/~kevinh/linuxcomm.html
However, I think the problem is that Sun's API has changed since the RXTX How-To was written. Try downloading the 'comm.jar' at the bottom of the page. It says:
comm.jar, 2.0.3, generic, English (3rd party backward compatibility, only), EnglishUnzip it and copy the comm.jar file to the 'jre/lib/ext' folder of the JDK/JVM where everything else RXTX created was placed.
After doing this the SerialDemo app started for me without errors.

Deploying Java Comm API

Hi,
I am developing an applet which uses Java Comm API. I'm running into some deployment issue. My understanding is that Java Comm API needs to have win32com.dll and javax.comm.properties files installed on the client machine for my applet to use Comm API. Is there a way around this? The ideal way will be to have everything (win32com.dll and javax.comm.properties) in a jar file so that it doesn't need to install any file on the client machine. However looking at previous posts, I don't think that's possible with Java Plug-in. Will I be able to utilize Java WebStart to accomplish this? I'll be interested to find how other people deploy Java Comm API. Thanks in advance.
Regards,
Joy

I�ve developed a solution to this problem. I created a class that creates the javax.comm.properties file where the comm.jar lib looks for it. The trick is to run the method that creates the file before the lib looks for it.
I show you the example of my code:
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;
public final class PrinterInit {
    public static void printerInit(){
        String archivoConf =
            System.getProperty("java.home") + File.separator + "lib" +
            File.separator + "javax.comm.properties";
        try {
            BufferedWriter out = new BufferedWriter(new FileWriter(archivoConf));
            out.write(
                "#"+ "\n" +
                "# Drivers loaded by the Java Communications API standard extension"+ "\n" +
                "# at initialization time "+ "\n" +
                "# "+ "\n" +
                "# Format: "+ "\n" +
                "#   Each line must contain ONE driver definition only "+ "\n" +
                "#   Each line must be of the form: "+ "\n" +
                "#           driver=<ClassName> "+ "\n" +
                "#       No spaces or tabs in the line. "+ "\n" +
                "#       ClassName must implement the interface javax.comm.CommDriver "+ "\n" +
                "#           example: driver=Win32Serial"+ "\n" +
                "#   "+ "\n" +
                "#"+ "\n" +
                "# The hash(#) character indicates comment till end of line."+ "\n" +
                "#"+ "\n" +
                "# Windows Serial Driver"+ "\n" +
                "Driver=com.sun.comm.Win32Driver" + "\n");
            out.close();
        } catch (IOException e) {
            System.err.println("No se pudo crear el archivo:" + "javax.comm.properties");
            System.err.println("Ruta completa:" + archivoConf);
}Before opening the port I call
PrinterInit.printerInit();This example writes de javax.comm.properties file needed for a windows implementation. You can change the value of the Driver property for the system you are using.
Good Luck!

How to distrubute java communication api ?

hi , I have a java project using java comm api (comm.jar) I need to distrubute it to clients (because it is an applet based app) without any user interactivity.
First I remember Webstart but somewhere I read some bugs about comm.api and webstart so I want to ask first Is there any people here used to developed and distrubute comm.api before ? What did you used ?
My clients has no knowledge about computers,so It should be some automatic process.

What about my suggestion in your original post regarding the same question?

Exception while using Java Comm and Java Web Start together

Hello Java Experts!
Here's the problem that's been bothering me. The application i'm developing uses Java Comm API to listen to Serial Ports. The application works absolutely fine when it is run locally.
Now, I need to deploy this remotely using java web start. All resources(dependent jar files) are present on the server and are referenced properly in the JNLP file. All jar files are signed properly.
Still, it throws the following exception.
java.lang.NullPointerException: name can't be null
     at java.io.FilePermission.init(Unknown Source)
     at java.io.FilePermission.<init>(Unknown Source)
     at java.lang.SecurityManager.checkDelete(Unknown Source)
     at javax.comm.CommPortIdentifier.getPortIdentifiers(CommPortIdentifier.java:70)
The exact line of code where it apparently seems to error out is...
Enumeration portList = CommPortIdentifier.getPortIdentifiers();
Are there any security issues involved here? Can a application deployed through java web start access serial ports on the system?
Any pointers as to what the problem might be would be much appreciated.
Thanks in advance!

I have the IBM Communications API. I've
been told that it works with Java Web Start but I
have not tried it. IBM has changed it's download site
so.... I can't point you to it. But I have it(55k zip'ed)
and can send it to you if you post your E-Mail address
of where you would like it sent.
Bruce Houghton
PS If it does work with Web Start please post the
news here. I will be watching.

The Java Function Activity Agent is not certified for Oracle Workflow embedded in Oracle Applications. Installing standalone workflow should be a lot easier than what you have found, although it looks like you did hit a Pentium 4 issue with the Oracle Universal Installer.

Hello,
I want to know how to do SAVE AS DRAFT using Java
mail Api.
thanksI don't think you can. That sounds like a feature of a mail client app itself. The Java mail API is for when you're ready to actually send the thing. Saving drafts is storing them somewhere like you would any other data; nothing to do with the mail API.

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).
