How to run a swing based client server application in web?

hi ,
wat hav 2 do to run a swing based client server application in web?

Swing applications run on the client only. You have two basic options:
1) turn the app into an applet so it can run inside the browser (but still on the client)
2) use webstart to allow the swing application to automatically install on the client from your server.

HELP - problem in running SSLSocket client/server application

Hi,
I want to create a SSLSocket based client/server application for this i have used EchoServer.Java and EchoClient.Java files. Both files are successfully compiled and when i ran EchoServer it throws an exception "Server certificate not found".
I want to make a complete auto-controlled client/server application which will automatically gets certificate and all configuration itself from program because i will use both client and server application in as a servlet part.
I did as per following instructions:
-Create a keystore to hold the private and public keys for the server. e.g.
keytool -genkey -keystore mykeystore -alias "myalias" -keypass "mysecret"
-Export the X509 certificate from this store
keytool -export -alias "myalias" -keystore mykeystore -file mycertfile.cer
-Import this into a trustStore for the client
keytool -import -alias "myalias" -keystore mytruststore -file mycertfile.cer
-Run the server using the keystore
java -Djavax.net.ssl.keyStore=mykeystore -Djavax.net.ssl.keyStorePassword="mysecret" EchoServer
-Run the client using the truststore
java -Djavax.net.ssl.trustStore=mytruststore -Djavax.net.ssl.trustStorePassword="mysecret" EchoClient localhost

How to validate a server in client-server application

I am considering a client server application for a masters project. One of the core requirements for this application would be to ensure that the server could not be replaced. This would be easy to do using public/private keys. The client creates a message and encrypts using servers public key, then sends to the server. The server decrypts, processes, creates response, and encrypts using its private key. This works, however the public and private keys need to be in the source code. It looks like keystores may fix that problem, however the password to the key store would then be required. For this application to be usefull, I need to find a way to embed a password or encryption key in a .classfile in a way that it can not be retrieved by decompiling or parsing for strings. Anyone have ideas on how this could be done, or a different method I could use to guarantee that the response coming from a server process is from my server program and not a fake program?

More detail. The program is a network license server (not web based). We need a simple license server for internal use, so that we can track usage and limit concurrent users for custom software. We also need some security so that people can not take the software home and use it. We have looked at commercial applications, however they are very expensive and we can not justify the cost since this is for internal software. There are 3 main pieces to a license server, the client libraries, the server, and the key generator. For the license server to be usefull, it should be impossible (or very very difficult) for someone to generate their own keys and add them to the license server. It should also be very difficult for them to create a fake license server that will grant licenses to clients without needing keys. If public/private key encryption is used, then the client would need to know the servers public key and their private key. These keys would need to be compiled into the program, stored in a key store, or looked up at run time from some other resource. The server would need to know its private key, and the clients public key. Since this is internal software, we can limit access to the server software, so it would be ok to compile the keys into the code (not ideal but secure enough for out use). However if I use this program as my Masters project, I would need to figure out a better way to secure it. The generic problem is how to give someone two programs that talk to each other, and be able to ensure that they do not fake one of the programs?

How to run a sample Jolt client

Can any one explain me how to run a sample jolt client.
Iam trying to run the following jolt client code ToUpper.java at the command prompt but I am getting the following error.I am getting the same error when i run the Jrepository Applet RE.html.

Hi Todd,
I am not getting the jcheckauthentication error now as i changed the port no. to the port where JSL is running.Now I am getting this error.Also find the ULOG contents pasted below.
D:\bea\tuxedo9.1\samples\jolt\ToUpper>java ToUpper
Authentication Level set To :0
Exception caught error no is:6
bea.jolt.ServiceException: TPENOENT - no entry found

at bea.jolt.JoltRemoteService.call(JoltRemoteService.java:267)
at ToUpper.main(ToUpper.java:39)
I have checked the jrepository file and also the Applet window for the service defination(TOUPPER)but still its not recognizing the service.Is there some configuration thing I have missed out before running JOLT client.

How to start an Swing based Application with a display of an Image

I want that when I run my swing based application, first a specified image should me displayed

I was talking about the determination of the resolution of image in (int). Resolution means number of pixels in per unit area of the image, I think it has nothing to do with image magnification. If you have some another idea ,tell me on [email protected]

Servlet in client/server application?

hi,
I am planing to make a client server application( SWING & an OODB), would it be clever to use servlet ( not httpservlet) as midle tier framework?
If yes , what are the benefits?
Thanks.

thanks for responding
actually my client don't wanna run a separate server application on the hosting machine as it costs too much, so thats why i think there is no other way to achieve the task rather than using servlets.
please do help me or atleast give me a suggestion. actually i'm developing an internet messenger application. i have developed it using client/server application model in which both (the swing client and the server) uses java sockets to communicate with each other. but now i want to develop the server side of the messenger as servlets. but as far as i know the servlets follow the request/response model. if i follow that model i have to use some sort of client pull after certain amount of time say after five or ten seconds, and this approach does not fulfill my requirements as it would slow the performance if there are hundreds of clients calling the servlet every 5 seconds. thus i want to create persisted connections between the client and the servlet which last for the life time of the user's session. also it is important for the data integrity of the application, so please help me in this matter as i have no other source of guidence in this meany world. i hope you will certainely help me in this matter. please mention that if there are any drawbacks of my approach i mean the persisted connections.
thanks you a lot

Should i use secure sockets for my whole client/server application?

Hi,
I have a client server application, and I want to ensure that the login process is secure (i.e. use secure sockets). but I dont know how to switch back to a normal socket once that is done.
So I am left thinking that i should just use SSL for my whole application, which can last pretty long. But I would rather not. Is there any other way of doing this?
or should I just encrypt the login info using MD5 or something like that, then send it over an unsecure socket?
thanks!

Hey,
Are you sure you haven't confused JGSS for JSSE?
Imagine you have a client-server system and you sometimes want data sent over the wire to be encrypted... JGSS offers you this flexibility; if you a encrypted transmission, run ift through JGSS before transmitting it; if you don't want an encrypted transmission, bypass JGSS and just send the transmission.
The benefit is the security (encryption) isn't hard-wired into you communications protocol i.e. TLS. JGSS has nothing to do with connections it is just protocol for securing messages, not sending them.
You would need to establish the secure context but this could be done at startup and persist for the duration of you applicaiton invocation. You perhaps might need to implement a mechanism to identify encrypted messages on the receiving peer (so it knows to attempt decryption).
Admittedly, kerberos seems like one of those 'inside-joke' things. I've come to realise if you don't have some sort of kerberos realm/server against which to authenticate - you need to swap it out as the underlying mechanism. How this is done I'm not sure yet, but I intend to find out today....further down the rabbit hole I go!
If I discover anything helpful, I will let you know.
Warm regards,
D

Client server application using CORBA

Hi
I have a basic client server application running using CORBA/idl where the client starts up and the server says hello back to the client. I have figured out the basics but would like some help with these small problems.
When I start the client, the server says hello. Thats OK. Now I want the client to start a simple java app (called c:\test.java - it works) that I created before. How?
The next bit is when I close down the app "test" that I start, I want the server to realise that its closing and simply say goodbye on the client. How?
If anybody can help me, I'd appreciate it.
Thanks for your time,
Shaun

hi,
to my knowledge, you will have to define a method in idl file and in your client, which server invocates(saying good bye etc) before shutting down..
ls.

Client/Server application question

Hey everyone,
I am trying to exercise on a client/server application. My client application is similar to this one [http://java.sun.com/developer/onlineTraining/Programming/BasicJava2/Code/SocketClient.java]. However this client works like this: it sends text through socket -> receive response from server. I am trying to find a way so that the client can receive and process messages from the server asynchronously. That is the server can send messages anytime (not just as a response to the client) and the client should always be able to receive messages from the served at any time, and not just after it sent something. I believe that multithreading would be the answer, listening to the output stream and sending through the input stream should be run in parallel, but I can't find a way to implement it. Your help is appreciated. Thank you.

I knew that :-) but how exactly?
How do I translate this code into two runnable classes which will communicate with the original class and its gui?
//Send data over socket
          String text = textField.getText();
          out.println(text);
       textField.setText(new String(""));
//Receive text from server
       try{
       String line = in.readLine();
          System.out.println("Text received :" + line);
       } catch (IOException e){
      System.out.println("Read failed");
             System.exit(1);
}

Problem using the File Dialog Box in a Client/Server application

I am developping a client-server application using Labview 5.1 . The application on the server acquires data from some instruments and saves it on file, while the application on the clients displayes such acquired data. For doing this I call some routines on the server via the "Open Application vi" (remote connection). All goes well except when I open on the server the "File Dialog Box vi" : in this case the application on the clients is blocked (is blocked the execution of the called vi on the server). Only when
the File Dialog Box on the server is closed, the execution of the called vi on the server starts again.
I need to use the File Dialog Box on the server, but I don' t want to stop at the same time
the clients !!
I need help for resolving such problem.
Many thanks in advance !!!

Hi!

"It seems that the VIs called by the clients are running in the user interface thread.
A call to the file dialog box will call a modal system dialog. So LV can't go on executing VIs in the user interface thread."
Are you sure? I think, that File Dialog, called by LabVIEW File Dialog from Advanced File Functions Palette doesn't blocking any cycles in subVI, which running in UI Thread. Look in my old example (that was prepared for other topic, but may be good for this topic too).
2 linus:
I think, you must a little bit reorganize you application for to do this. You must put your File Dialog into separated cycle. This cycle, of course, will be blocked when File Dialog appear on the screen. But other cy
cle, which responsible for visualization will run continuosly at the same time...

Client/server application under development

Hi there,
I've been working on a client/server application that includes chat and whiteboard features. In terms of how the client app communicates with the server app, my initial thought was to just go with xml, until I reached a snag. Everything about chat and almost everything that is accomplished on the whiteboard can be expressed in terms of text or character data; which what makes xml a good candidate for moving the data back and forth from client to server. However, there's one part of the whiteboard feature that can't be converted to just text. The whiteboard has an ImageTool. With it you can select an image (gif,jpg) from your harddrive and load it into the whiteboard. An image is binary data and simply cannot be put into an xml file for transport. At least, that's my understanding. Am I wrong about this?
So, this poses the questions: "How do other similar applications like MSN Messenger move images around? If they're not using xml as there medium, what are they using? Just plain sockets without any structured medium like xml?"
Please advise,
Alan

You could always Base64 encode the image file content and then put the Base64 in XML.
I am in the middle of a client-server project and I use XStream ( http://xstream.codehaus.org/ ) to convert Objects to XML automatically. I don't have to do any explicit encoding - XStream does it all for me.

Client Server Application with images or icons

I made a Client Server application with JFrames, but I put a jLabel with an icon, and I can't run the Client.
It says java.lang.NullPointerException
Do you know why I can't see the icon in the JLabel? It isn't an applet, it's an application with JFrames.

You have to explain the problem better if you want some help. Also show the code which is giving you the nullpointerexception(Do not forget codetags!).

Are there any Client/Server Application (using sockets) design patterns?

Hi,
The title of the post nearly says it all. I am searching for different design patterns related with the development of a client/server application. I understand that there must be any different ways on how a client/server application can be developed.
