Use of communications API

Communication API is used for windows platform, with win32comm.dll file & it is working satisfactorily. But the same is not working with Novell. It asks for win32com.nlm file, where do I get it?
How to shutdown windows 98/95 through java application?

I don't think COMM API are supported in Novell. I think that they are only for Windows and Solarias but actually there is a port for Linux and BSD too (it is called RXTX).
To shutdown windows 9x try this:
Runtime.exec("rundll32 user32.dll,ExitWindowsEx");

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 !

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.

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)

Use of JTA API in JDBC programs.

Hi,
Where we can use JTA API in JDBC programs. what is the significance of UserTransaction interface in JDBC programs. I heard that when we are using two databases in same program then we use this JTA API. Can't we do this by using,
connection.setAutoCommint(false);
// code to work with two database
connection.commit();
does it wont work.
Please suggest me.
Thanks
Satish

I heard that when we are using two
databases in same program then we use this JTA API.
Can't we do this by using,
connection.setAutoCommint(false);
// code to work with two database
connection.commit();This will work if there are no errors or crashes, but it can seriously fail otherwise.
To find out more: you can download our JTA from http://www.atomikos.com and go through the JTA user guide. It includes the answer to your question.
Alternatively, feel free to check our transactions community forum on http://www.atomikos-support.com/forums (which we check more often than this one).

Does the Communications API work with Studio 4

I just installed Studio 4 along with the JDK. The Java version that I am running now is:
java version "1.4.1_02"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_02-b06)
Java HotSpot(TM) Client VM (build 1.4.1_02-b06, mixed mode)
Running on MS XP.
The Communications API seemed to work just fine on JDK 1.3 with Forte 1.0.
I installed the Comm API as instructed and set my ClassPath:
CLASSPATH=D:\PROGRA~1\s1studio_jdk\j2sdk1.4.1_02\lib\comm.jar;D:\MyProjects\java\GarxFace
A call to:
Enumeration portList;
portList = CommPortIdentifier.getPortIdentifiers();
does not yield any ports at all.
Stranger yet, if I use the auto complete feature in the editor. For example if I type: m_PortID. then no members of PortID show up.
But the code compiles just fine.
Any idea what is going on?

First I found the reason that the auto complete was not working. I had to mount the comm.jar file (you did not have to do this in Forte 1,0, just set the classpath). I thought that I had done that. That is the problem when you work late. ;)
Here is a eexcerpt that I found on a search in another post:
Copy javax.comm.properties to your <JDK>\lib directory.
C:\>copy c:\commapi\javax.comm.properties c:\jdk1.1.6\lib
The javax.comm.properties file must be installed. If it is not, no ports will be found by the system.
Notice it says that "javax.comm.properties file must be installed"
javax.comm.properties is indeed installed in my JDK lib subrirectory, but it is almost like it is not being found.

How to use search REST api to get custom managed property data for anonymous user?

I am trying build a public portal with anonymous access and i am trying to read some
content from custom managed property using search REST api in sharepoint 2013. I have tried to enable all possible attributes of the managed prop. Like searchable,queryable,safe etc. also i am including queryparametertemplate in my REST api search query. But
still i am not able to retrieve the managed prop. For an anonymous user. The same query returns the value if i am logged in.
Any Help is greatly appreciated.
Thanks,
Rakesh
Thanks, Rakesh

Hi Rakesh,
To enable anonymous Search REST queries, we need to create queryparametertemplate.xml and upload it to the correct library in SharePoint.
From your description I can know that you have created the file, then I recommend to check the things below:
Please use “QueryTemplatePropertiesUrl” instead of “queryparametertemplate” in the Search REST API query as following: &QueryTemplatePropertiesUrl='spfile://webroot/queryparametertemplate.xml'.
Make sure that the Query Properties you need have been added to the QueryProperties element in the queryparametertemplate.xml file.
Make sure that the query parameters you need have been added to the WhiteList element in the
queryparametertemplate.xml file. For example, if you want to use Refiners in the REST API, then the Refiners should be added to the
WhiteList element in the queryparametertemplate.xml file as following:
<a:string>Refiners</a:string>.
You can also debug setting properties in anonymous Search Rest queries following the link below:
http://www.mavention.com/blog/debugging-setting-properties-anonymous-search-rest-queries
More references about anonymous Search REST:

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

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.

Using Dynamic Configuration api for SOAP adapter

I want to use Dynamic Configuration api to send a SOAP request to a webservice.
tha value in my adapter is
my Target URL is
http://xidr3.bcs.de:50000/XISOAPAdapter/MessageServlet? channel=:Routing2_Service:SS_SOAP_Sender_Working_June12&nosoap=true
which is the corresponding field i have to set in Dynamic Configuration?
I have written the following code is this right?
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
String temp = "http:/"+"/sap.com/xi/XI/System/SOAP";
DynamicConfigurationKey key = DynamicConfigurationKey.create(temp, "TServerLocation");
String varURL =
"http:/"+"/xidr3.bcs.de:50000/XISOAPAdapter/MessageServlet?channel=:Routing2_Service:SS_SOAP_Sender_Working_June12&nosoap=true";
conf.put(key,varURL);
return "";

Hi,
Yes, your code looks fine. Can you let me know what is the error you are getting. Have you checked the Flag in your communication channel.
Use Adapter-Specific Message Attributes
Variable Transport Binding
Once you test your scenario you can see the Dynamic URL in your message Header by going to tcode sxmb_moni. See if you are able to find something called DynamicConfiguration in your message haeader. If yes what is the value set there.
PS: From the target URL you posted It looks like your webservice is hosted on the XI box itself. Is it the same XI box or different box? Just curious to know.
Reward point if answer is helpful

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.

Communications API

To all;
Does anybody know if Sun's, or IBM's Communications API works with Win Modems.
Symptoms;
Both COM1 and COM2 are disabled in the BIOS of my PC.
My Win Modem is installed and working fine using COM1(its a PCI modem).
From MS-DOS Prompt I key mode COM1:
I get Illegal Device in Return.
From My Java Program that uses Communications API, I get noSuchPortException.
If I enable both COM1, and COM2 in the BIOS, set
up my modem to use COM3, the DOS mode works
for both COM1 and COM2, but not COM3.
My Java program also finds COM1, and COM2, but
not COM3.
Any body have any experience with this?
Bruce Houghton

No luck yet???
