CORBA Client- Server and Server- Client?

Is it possible to do Server-> client invocation through CORBA?
Would I have to create some type of callbakc object to the client?
Need direction, i was thrown into corba and have no idea about the limitations.

if anyone is interested in corba callbacks this has something about it

One is for the base version of the Mac OS, the other is for the Server version. You can only install the one that matches your system.

Bluetooth communication between J2SE server and J2ME client

Hi everyone!
I'm new here in this forum...
I try to make a small project to my studies,
My project will include J2SE server and J2ME client.
I'm stuck in the step of finding the server with the wireless toolkit emulator.
I found this issue in old subject: here
I try the solution in reply 6 but I don't understand exactly who to define kvem.home, and I got this error:
" You must define the system property "kvem.home" "
maybe someone can help me and explain how to do that?
thanks!

Hello,
I want to find out how this can be done, too. I tried with
System.setProperty("kvem.home", "C:\\WTK2.5.2");but I get an error:
java.lang.UnsatisfiedLinkError: com.sun.kvem.jsr082.impl.bluetooth.BluetoothController.setSystemProperty(Ljava/lang/String;Ljava/lang/String;)I included these files in the build path:
c:\WTK2.5.2\wtklib\gcf-op.jar
c:\WTK2.5.2\wtklib\kenv.zip
c:\WTK2.5.2\wtklib\kvem.jar
and I import com.sun.kvem.bluetooth.*;
I'd appreciate any help.

Difference between client proxy and server proxy

hi all,
could u explain me the differences between client proxy and server proxy,
regards,
AVR

Hi AV,
simple search in sdn may answer your question,
There are two type of Proxy's in ABAP and JAVA(Clinet and Server),
Clinet ABAP proxy used to send message from ANY SAP System to Integration server,in this case XI adapter not required .
Server ABAP proxy used to send messages from Intergration server to any SAP System,in this case XI Adapter required.
How to implement ABAP proxy comunication refer below link
http://wiki.sdn.sap.com/wiki/display/stage/ABAPproxyproviderimplementationand+testing
The sama way Client JAVA proxy used to send message to Integration sever from any Web Application ,
Server JAVA proxy used to send messages to any destination system ,in both cases XI adapter required.

Strange problem with AIX server and windows clients

I am having a real bizzare problem with WLS 7.0.1 running on AIX 5.1 and
clients on windows. We have J2SE Swing application as a client.
If the client is w2k or XP, the first client gets good response. If I start
another client the second client is horribly slow (2 sec vs 16 sec). Even if
I kill the first client the second client continues to be slow. If I have 2
clients open together, the first one continues giving 2 sec response while
the second one continues with 16 sec. For that matter if I start another
client after shutting down first one I get slow (16 sec) response.
If the client is NT client I always get good and consistent response from
the server. Irrespective of how many client I have on the NT machine, I keep
getting good response. NT and W2K laptops are seating right next to each
other on the same n/w and infact the NT is a much slower and lessor memory
machine than W2K.
We did similar tests keeping server on Solaris or NT server or W2K server,
and the clients "behave" normally i.e I get consistent repsponse time (it
may be slow or fast, but it is consistent and is consistent b/w NT and W2K).
We even tried putting my laptop on the same network as the AIX server, but
it did not help. Unfortunately some of our clients will be using AIX and
W2K.
HELP!!!!

Sounds like a reverse DNS lookup or similar network timeout.Thanks for the suggestion, but then why would the first client on w2k or XP
get a better performance and the subsequent clients get worse performance?

Get ip address of client machine and server

Respected experts,
I want to get ip address of the client machin and server machine.
Which method should i use for getting this.

drvijayy2k2 wrote:
hi
i am not sure
but try request / servletrequest -> getRemoteHost() and getLocalHost()There isn't any getLocalHost() method for HTTPServletRequest. And in anycase, the getXXXHost() methods would return the hostname. You'll only get an IP address if the name cannot be resolved.
@OP:
[getRemoteAddr()|http://java.sun.com/javaee/5/docs/api/javax/servlet/ServletRequest.html#getRemoteAddr()] - be warned that this may be the IP address of the last proxy in the chain
[getLocalAddr()|http://java.sun.com/javaee/5/docs/api/javax/servlet/ServletRequest.html#getLocalAddr()] - this is the address of the interface that the request came in on, so for a server with multiple NICs, you will only be getting one possible IP address.

HT201320 What is incoming and outgoing mail server and server port number

What is incoming and outgoing mail server and server port number

See applenerd504 previous reply:
These specifications that allow you to send and receive messages on your iPhone. If you are using iCloud Mail, Gmail, or another service listed in the selector in settings, they should be automatically configured. If not, you may need to look up certain numbers for your email service.
Putting it in slightly different terms:
If you are using a web-mail system like gmail (with a gmail email address) all the mail sending, receiving and management is done on Google servers. In these cases you will only need to have a working internet connection to be able to log in to the service to access its data.
Supplying mail sever names and port numbers should only be needed if you are using a traditional (non-web) email account where you are accessing the mail servers directly. This would be typical for a email account set up by someone like your ISP (Internet Service Provider), in these cases you will have to ask them for the appropriate settings.

Do client's and server's JVM need to be from same vendor?

Hi,
1) Is a reference to object in the server valid in client if a different vendord JVM is used?
Each JVM vendor implements references in a different way.
Say client's JVM is Microsoft and Server's is SUN
in such a situation will a remote reference be interpreted correctly in client's JVM?
2) What are contents of a object-reference?
I know that it depends on implementation.
How does sun do?
are both declared datatypes and runtime type of references stored?
If so where?
An object has both data and methods(class instance)
Therefore will it have 1 ptr to where data is stored
and one pointer to class instance for access to methods
Then where are decalared and defined reference types stored

No they do not. See, the JVM is nothing more than a specification, like CORBA. What is an implementation of CORBA? an orb, right? You can be sure that every ORB out there implements the full spec of corba......they do so differently, but they MUST do so. The same with JVMs. They're impl style can be different, but they MUST fulfill all the specs of what is called the JVM.

How to setup iCal on a Lion server and its client machines?

I recently bought a new mini server (running Lion) in order to share our iCal calenders (like in the Apple presentations). I thought this would be an easy process but apparently it isn't. So what was I already able to achieve:
1) Set up 5 different clients (on the Lion server), with corresponding e-mailadresses and passwords.
2) Activated iCal on the server preference window (ical: on)
3) Tried to add the user a account on one of the five client machines => HERE it goes wrong.
My main issue is that I'm not able to add a user account on a client machine and have it connected to the server.
It would be really nice if someone could assist me with it.
Warm Regards

I posted additional information online using the newly created Launchpad login Service account.
I hope that explains my situation, if not I will add more detail here.
There is no problem, when ither of the two OS are used to enable printing with the HP Deskjet 2050 J510 series printer.
The problem begins when I try to print from the other OS , when connected to one of the Operating System.
I have tried without success to print from Windows 7 Ultimate 64-bit OS from an HP Deskjet 2050 J510 series connected to a Ubuntu 12.04 LTS server with Amahi (HDA), installed.
The same thing occurred when I tried to print from the Ubuntu server and the printer was connected to the Windows 7 Ultimate 64-bit running P.C.

Java server and C# client

Hallo,
Please, Can you help me. I´m looking for Java server run on the Linux Debian.
The Server in Java must be very good implementation (connect many client-500workstation).
I have workstation ( Microsoft Windows XP, 7 ) and on the workstation must be client(in C#).
The client say: a need information from Database and connecting to the Server in Java. The server in Java
connect to the - Database(Oracle) and send information back to the workstation
and workstation save as file.This is process before starting Windows, I need information
for the starting script.
For the Example, I have in databese name of instalation pack.
Example implemention :
On the workstation running agent.exe as service. I say in my script:
(agent.exe -IdPack) and my agent connect to the Server and downloading information and save to the
file(for example XML) in computer.
Please, Do you know any solution?Any source code?project?
I think, the server on the linux can be implementation in java servlet or next programming language.
Thank You. Lukas

The information we need on the workstation windows and I need downloading from Database in Oracle and I need server which connect to the database and send back to the workstation the information. Do you understand me?So you have information in a database, and want some way of having that information accessible on Windows desktops? I don't see any need for C# clients here, surely a simple web app in a container like Tomcat will suffice? How complex is this information? In fact, so far I haven't seen any reason why you even need Java here. Can't you just throw some PHP at it? Where does C# come into the equation? Writing a custom rich client can often be avoided by using a web browser, especially if it's just a matter of taking some data from a DB and displaying it - makes your life much simpler.

Bluetooth simulation between J2SE server and J2ME client

hi there,
I have a working bluetooth client/server application (using BlueCove), with the server on a PC (the PC has bluetooth hardware) and the client on a mobile telephone.
I wish to move the application to a bluetooth simulated environment, however.
To simulate bluetooth between 2 mobiles, I could open 2 instances of the WTK simulator and the mobiles will find each other -- but this doesn't meet my needs. I wish to simulate the bluetooth environment between a J2SE server and a J2ME client.
Can I do this using the wireless toolkit? Does anyone have other ideas?
thanks,
Manoj

OK - I have the solution.
My PC (server) code used BlueCove to talk to the bluetooth stack. The trick is to use Sun's own KVM packages. This creates a virtual bluetooth device on your machine, shared by the WTK emulator.
Here's the server code:
package com.encube;
import java.awt.BorderLayout;

import javax.microedition.io.Connector;

     public static final String SERVICE_NAME = "BTCHATSVR";
     private StreamConnectionNotifier server;
     JFrame jframe;
     JTextArea textArea;
     public static void main(String[] args) {
          Server svr = new Server();
          svr.doWork();
     public void doWork() {
          this.jframe = new JFrame("BT Server");
          this.jframe.setLayout(new BorderLayout());
          this.textArea = new JTextArea(6, 20);
          JScrollPane jsp = new JScrollPane(this.textArea);

          this.jframe.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          this.jframe.setVisible(true);
          startServer();
     public void logMessage(String message) {
          this.textArea.setText(this.textArea.getText() + message + "\n");
          this.textArea.setCaretPosition(this.textArea.getText().length());
     public void startServer() {
          LocalDevice local;
          try {
               local = LocalDevice.getLocalDevice();
               local.setDiscoverable(DiscoveryAgent.GIAC);
               this.logMessage("max of "
                         + LocalDevice
                                   .getProperty("bluetooth.connected.devices.max")
                         + " connection(s) supported");
               String url = "btspp://localhost:" + UUID_STRING + ";name="
                         + SERVICE_NAME;
               server = (StreamConnectionNotifier) Connector.open(url);
               this.logMessage("waiting for connection...");
               StreamConnection conn = server.acceptAndOpen();
               this.logMessage("connection opened");
               InputStream is = conn.openInputStream();
               byte buffer[] = new byte[1000];
               while (true) {
                    int numChars = is.read(buffer);
                    String s = new String(buffer);
                    logMessage("received from mobile phone: " + s.substring(0, numChars));
          } catch (Exception e) {
               this.logMessage(e.getMessage());
}You need to include the location of WTK as the kvem.home define. If its installed in c:\wtk22 (the default), start the server with the parameter -Dkvem.home="c:\wtk22". You also need to include these 3 libraries:
c:\wtk22\wtklib\gcf-op.jar
c:\wtk22\wtklib\kenv.zip
c:\wtk22\wtklib\kvem.jar
That's it for the server. My code of the sample client (the mobile phone, running in the WTK emulator) is messy (sorry about that -- still cleaning it up)!

...and that's it. Start the server, then the client (all on the same machine) and you've simulated bluetooth between the 2.
To get the server working with a real mobile, you'll need to use the BlueCove library instead of the 3 WTK jars (and can remove the kvem.home directive as well). The rest of the code should remain the same (haven't quite tested that yet!).

RMI Server and RMI Client Problem

First, Hi!
I have create my RMI Server and a RMI Servlet client.
I can run the server and servlet first time and it works fine.
Then, I stop rmiregistry and server.
Then, I start rmiregistry and server for a second time but my RMI Servlet client gets a
java.rmi.ConnectException: Connection refused to host: xxx.xxx.xxx.xxx; nested exception is: java.net.ConnectException: Connection refused
If I copy the class again where the servlets resides, it works again. But I have to keep doing that. I have to keep copying the class file to the servlet directory every 2nd time I try to run it for it to work.
Anyone know what am I doing wrong?

If I copy the class again where the servlets resides,which class file ? u mean RMIServer's class files ??
I have faced the same problem too. In my case if i just restart my Tomcat webserver the error goes and the servlet is very well able to connect back to the RMI Server
it works again. But I have to keep doing that. I have
to keep copying the class file to the servlet
directory every 2nd time I try to run it for it to
work.

9i server and vista clients

Hello,
we have 9i server and were running 9i clients on windows 2000. Now some clients were upgraded to windows vista, so what version of oracle client shall we use to be compatible with vista ? Do we need to upgrade the server as well ?
Thank you for answers.

Which 9i version ? 9.1 or 9.2 ? You can use a 10g client to connect to 9.2 database.
