Need xp performance tool to monitor client-server apps

My Xp/Oracle 61 forms are causing the application to "stall" when many images are displayed. I need a tool that tells me what threshold is hit- to at least point me in the right direction. Is it memory, cpu, graphics cards, what? The XP supplied performance tools are not satisifactory. I need something that is a little more telling. Tell me Oracle, or users who have been where I am going , what is a good tool to isolate the "real" problem?

How to design socket client-server app for 2-way communication

Hi, I am writing a client-server application. I have a single server and many clients. Each client will need the ability to send information to the server at any time. The server will also need the ability to send information to a client at any time. Its this second part that I am not sure how to design. Would I need to create a SocketServer on each client to accept incoming messages, or is there a better way? Thanks

Don't my requirements sound a lot like an IM application, where a chat server might need to send a message to a chat client at any time?Not really. If that is what you are designing
in my opinion one could easily be forgiven for thinking you were deliberately obfuscating your goal...
How does the server know where the client is? Does it know the IP address of the client?I would imagine the server would contain a directory of IPs? I'm not sure.
What happens if the client is not running?Then I guess the message would not get delivered.
What happens if the client is behind a firewall that does not allow incoming connections?How do IM chat clients work? How have people solved this in the past?Typically the server would only care about clients currently connected to the server.
Maybe you should re-think your design. I don't really have a design, just requirements, that's why I'm writing this post.Your subject says "+How to *design* socket client-server app for 2-way communication+".
Are you saying you expect someone else to do the design for you?

Lotus Notes Client Server Apps

I'm wondering if anyone has tried to connect to lotus notes client server apps. from portal. I've heard that they have to be "webified" first. Is that true or are there different ways to get to the lotus notes app?

Help needed on TCP/IP Multi-port Client-Server

Hi all, I am trying to develop a client-server application to stream some data over a few random port numbers (defined by myself) to stream data over to the TCP server (i.e another computer) in LabVIEW. So far, I have created my application using the NI examples for "Simple Data Client + Server" and it works fine. I also understand that the "TCP Listen" VI is only able to listen for 1 TCP connection only and a way around this is to use queueing idea to receive & process the incoming data.The downside to the idea is that the "base port" (i.e initial port) needs to be the same (on every TCP client) with the TCP Server and it is not fit for the purpose I intended.
Basically on the TCP server side, i need to chart/monitor the data on different port numbers that is being streamed real-time from the one TCP client computer. Is this possible in LabVIEW?
Can anyone (incl. NI gurus) advise and point me in the right direction?

Hi
http://zone.ni.com/devzone/cda/epd/p/id/2739 Here you can download that component.But you can also use TCP icons which is available in Data Commmunications>Protocals>TCp for communication and to read and write data use variant to flattened string. I have attached a small example where i will transfer a constant string to the host PC to check the link between client and the server. Hope this helps you.

I Need Information about Open Source Java Client/Server Instant Messaging

I need your valuable help and collaboration with the following issue:
I need to know where can find a robust Open Source Java Instant Messaging Client/Server Application.
I thank in advance for their valuable time. And for the attention and the collaboration lent to me.

I was going to mention that right off, but since the OP is clearly unaware of the search engines on the Web, I thought I'd give him a hand. Jabber works pretty good - I tried it a while back and some of the clients were ... quirky.

Help Needed With Basic Client/Server App

I was wondering if anyone can help with a simple blackjack client/server application i've been writting (basically its a moddified chat application). The problem i'm having seems to lie within the connection management i've written.
What i'm trying to get is that only 4 players can connect at one time and that each player takes a turn (which i've implemented using threads) to play their hand (as you would if you were playing it for real). The problem is that it will allow the players to connect, but oddly enough, it will not allow a new transaction to be created (i.e. allow a player to take their turn) until 2 players have connected.
Even when it does create the transaction, after taking input from the client once, the server seems to stop doing anything without any error message of any kind.
Its really annoyed me now, so you guys are my last hope!
The code can be found in full here:
Client Application: http://stuweb3.cmp.uea.ac.uk/~y0241725/WinEchoClient.java
Server Application: http://stuweb3.cmp.uea.ac.uk/~y0241725/ThreadServer.java
Card Class: http://stuweb3.cmp.uea.ac.uk/~y0241725/Card.java
Deck Class: http://stuweb3.cmp.uea.ac.uk/~y0241725/Deck.java
Please feel free to play around with this code as much as you feel necessary!

Authetication problem in client/server app

I am presently developing a client/server program, and I'm wondering what will be the best form of authentication. I plan to develop a protocol for the programs, any deviation leading to socket closure. I thought about signatures, but I don't think any body's ready to vouch for me(ie I don't know how to go about signatures). Is there any help?

Creating chart in java client/server app.

Currently, I'm developing a client/server java app. under windows. I want to create a chart (pie, bar) for graphically reporting, anybody can help me pls........? Thanks a lot
TriAK

There are some solutions...You can use the Java Chart() class or BarChart() from the J2sdk API.
(http://java.sun.com/applets/jdk/1.4/demo/applets/BarChart/example1.html)
Besides, you can use some already build class from some companies like ObjectPlanet.(www.objectplanet.com).
There is also another link(have a look at it) http://www.java4less.com/charts_e.htm
Another way is to build by your own using java.awt(It will be to most difficult in the manner of time consumed).
Finally, I will recommend you to create charts as html page integrate this application as Applet or html in general(Javascript,JSP).
I hope I gave you some ideas.

Integrating DOS/client server apps through portal

Is there any partners out their that have developed any portlets that will integrate legacy client server or DOS through the portlet in a Citrix NFuse fashion?
There seems to be a few competitive portal providers out their who claim that this can be done. OBTree does this via Java wrapped emulation software which can be integrated over the web.
This would be very useful for legacy integration into one place without rewriting a front end etc.
Any ideas or recommendations?

Any one got idea how to resolve this problem. We are facing this problem with applet based applications. Pleae let me know if any one know how to write netlet rules to make this app. work through portal.

Advice on client server apps

Hi
i would like to discuss some ways to help improve the connection between a mobile device and a remote server using sockets and http connection.
on my N95 device and on T mobile network, i sometimes struggle to connect to the remove server and was wondering if there is a way to improve this.
would using UDP be ideal has i have heard from someone that TCP is generely not good for wireless connections. what wil be the best approach to improve the perfiormance of wireless devices communicating with a remote server? thanks

hi. first and foremost, both tcp & udp need internet connection irrespective of there modes of operations. tcp is connection oriented since the server has to be in constant communication with the client due to acknowledgement issues while udp does not need acknowledgement. now according to my experience the whole issue is with the cellular service provider companies; they need to make their networks efficient. in my country the internet just stops being there for some several minutes before it resumes and under such circumstances i think both tcp and udp are bound to affected.

Client/Server apps using custom objects

I have wrote an ip transaction server and I am trying to pass objects across to it that don't have to reside on the server. I have created an interface that implements serializable and then the class I am trying to pass implements the interface. I read that as long as the interface is on both the client and the server that the object doesn't need to be using this approach.
I, however, keep getting a classdefnotfound error for the custom object when I do a readObject().
Can this really be done?
Thanks in advance.
Relevant code snippets:
interface Workable implements java.io.Serializable
     public abstract int getToWork();
public class test1 implements Workable
     public int getToWork()
          System.out.println("Test 11 value = ");
          return 1;
Server code:
Workable ipdata;
ipdata = (Workable)in.readObject();//Blows up trying to read object here
ipdata.getToWork();

Take a look at the thread on this newsgroup named:
deserialization loads classes more eagerly than construction?
That seems similar to your complaint (Java's object serialization not conforming to its own specs about "classes that don't need to be present", in that thread it is a non-serializable member object that blocks things). I get the feeling you hit a bug in Java's serialization mechanism and that it is caused by a faulty heuristic in Java serialization.

Using Class Timer in a client/server app

In my program i d like the server execute draws every 5 min choosing numbers randomly from1 to 10.
Clients, when connected will inform server about the number they chose. (This works correctly)
Next, the clients will wait until notified by the server about the number drawn in the last draw and
about if they won or not.
i ve found that i have to use classes Timer and TimerTask but API does not help me enough
about how to use them. Could anyone help me?
Here is the piece of code i think it need to be changed.
// control thread's execution
      public void run()
         int message=0;
         int rnum=randGen.nextInt(10);
         display.append( "\n"+ "THE MAGIC NUMBER IS: " + rnum );
// process connection
         try {
            // read message from client
            do {
               try {
                  message = input.readInt();
                  if (message==rnum){output.writeUTF("SERVER>>> YOU WON: MAGIC NUMBER IS: " +rnum);}
                   else {output.writeUTF("SERVER>>> YOU LOSE: MAGIC NUMBER IS: " +rnum);}
                  display.append( "\n\n" +"PLAYER " + clientNumber + " SELECTED NUMBER " + message );
                  display.setCaretPosition( display.getText().length() );
               // process problems reading from client
               catch ( IOException ioException ) {
                  display.append( "\nUnknown object type received" );
            } while ( message!=-1 );
            display.append( "\nClient terminated connection" );
            display = null;
         // close streams and socket
         finally {
            try {
               output.close();
               input.close();
               connection.close();
            // process problems with I/O
            catch ( IOException ioException ) {
               ioException.printStackTrace();
            clients.remove( this );
      } // end method run


I just implemented something like this so I know what you are trying to do.
Basically TimerTask is an Abstract class, which means you can't make an instance of it. So TimeTask t = new TimeTask() won't work. Instead what you need to do is make your own class that extends TimerTask. You then need to implement the run() method which is abstract in TimerTask.
This sounds complicated at first, but it is very easy.
This is my DelayTimerTask:
import java.util.TimerTask;
*Author: Jon Parise
*email: [email protected]
public class DelayTimerTask extends TimerTask{
    private boolean timeExpired = false;
    /** Creates a new instance of DelayTimerTask */
    public DelayTimerTask() {
        timeExpired =false;
    public void run(){
        timeExpired =true;
    public boolean isExpired(){
        return this.timeExpired;
}All this class does is set a flag when it is run.
The Timer class schedules a TimerTask, in this case a DelayTimer. When the scheduled time comes, everything in run is executed, which in this case sets the flag.
To schedule the task do this:
Timer delayTimer = new Timer();
DelayTimerTask delayTimerTask = new DelayTimerTask();
delayTimer.schedule(delayTimerTask,5000);
while(!delayTimerTask.isExpired()){
     //DoSomething Here
}This will create a new delayTimer, and then schedule it to go off in 5 seconds(5000 millaseconds). When it goes off isExpired will become true and break you out of the loop.
Hope this helps,
Jon

JavaFX as a SaaS/ How good is it for Client-Server work?

I was under the impression that FX could be used to produce a Client-Server application as well as SaaS.
a member of another forum said "I'm sure you meant to say "Desktop". JavaFX will not be making inroads on the web as a client-side technology."
To which I said
There have been examples of FX used with EE
http://www.oracle.com/technetwork/java/javafx/samples/index.html
http://docs.oracle.com/javafx/2/overview/jfxpub-overview.htm
Sales Dashboard (DataApp)
DataApp is a client-server application for a fictional global automobile company called Henley Car Sales. Automobile sales are simulated on an EJB server using JavaDB, and the data is available via Derby and a RESTful web service. The client demonstrates a variety of data presentations by using a mix of FXML and JavaFX.
I thought originally that JavaFX was "Desktop" only also, until I found this example. I couldn't get it to run due to some weird Database line read issue that others also had. I'm not sure if this is now due to FX's integration, or if this was something new, but I believe I have seen another FX client-server app as well.
I'm not that familiar with the client-server side of Java yet, so if you have other Information I would like to know, because I am looking to design a Client-Server app with FX, and I don't see why it would be an issue, unless there are huge limitations."
He ended up saying "Those are still desktop apps. Sure, they are client-server in that they connect to a remote database. But they are still traditional fat-client apps rather than web-based thin-client SAAS web applications which, these days, most people will think of when you say "client".
My point is to be more precise when you use the word "client".
But if your point is just that JavaFX is taking over from Swing for the limited areas in which Swing is used, I have no insight into that area."
Now I don't really like attitudes when I get my question answered, but the high and mighty needs to stop. It clearly says Client-Server so I don't know why it's being denounced by this dude who thinks he obviously knows better.
Anyways he talks about it only being able to connect to a DB, to which it says it uses EE tech such as EBJ, Restful, and Derby, so that's more than just DB right(I don't know since I havent' learned that yet)?
It seems as if he's saying that only EE code can go up on a server? Or can SE code go up there as well?
I'm looking to design a SaaS software with FX, so if this isnt' possible I would like to know possible other options(or just having all of the gui work on the client, and the rest on the backend)???
Thanks!

This response is not a tutorial, I hope it gives you some verbiage to use in further searches.
SaaS to me means that the service is running on the server. If you have the server and permission to run java apps there then you can use Java FX by having the server shuttle requests to the Java FX app. But this is probably not the intent of Saas (it would be more appropriate to use a java implemented web service).
If you are using Netbeans then it is very easy to create demo projects; use "File/New Project" to run them on your local computer.
Example File/New Project/Java Web/Web Application will give you a hello world web site very quickly. This will 1) start either tomcat or glassfish as the server. 2) launch an html page with "hello world". then you can use java script to talk with the server via ajax. Using this approach you are going to need to study JSP or J2EE stuff.
After this is running you could start one of the Java Fx examples in Netbeans: File / New Project / Samples / WebViewBrowser. This will start a javaFX app that acts like a browser and runs on the client.
So, start the "hello world" app in netbeans by right clicking it in the project pain and selecting "debug". Then start the webviewBrowser app the same way to load that web page that has "hello world" in it as all browsers do. In the WebviewBrowser (which is java fx) you can get at the javascript in the web page and do all kinds of stuff. You'll need to search for webviewBrowser examples.
The above all assumes a Netbeans solution. But, as you probably know, there are no rules. The server can be in C++ and the client in C (or any other language). The server and client usally communicate via http or tcp. So you could have a server written in java (maybe J2ee or you can rewrite a http server from scratch which isn't that hard - search for "HttpServletRequest and HttpSession" ) and the client can be in Java FX (where the Java FX talks directly with the server via http (no javascript or web page in the middle) again there are probably hundreds of libraries to talk to a http server).
I use HttpServletRequest and HttpSession on the server side with MySQL and xml. On the client I use javaScript but I am moving to a strictly Java FX solution. This will give me close to 100% java on both sides and for my purposes this will work. (I may need a little html in the middle for drag and drop installation.) I am hoping that work continues with porting Java FX to most devices: Android, IOS, WinPhone. It is already on Linux, Windows Desktops and Mac.
