Pjc for client-server mode

hi,
i have been using pjc for customized text field and text area and have successfully implemented it on windows and sun solaris. we have used pjc for working in non english character set so that the user can directly type in the required character set without any supporting application to enable new keyboard mapping. but i have a serious problem.
these customized components work only on the webforms mode.i.e. on browser or applet. they dont work in the normal client server mode. is it possible that i can have them running in the normal runtime also. if yes then how and if not what is the work around for achieving the same without much effort.
awaiting a prompt reply.
thanks in advance,
regards,
Yousuf.
Delhi.

Dear Yousof,
I want to do the same thing that u'vve already acheived, I want to customize oracle forms texfields and instead of EXTENDING VTextfield I want to extend JTextfield and ofcourse implementing IView interface.
But I get problems, would u mind be kind enough to instruct me in doing that?
Best regrds,
Sasan

Client Server mode for time ten connection

Hi, I am new to Times Ten and got a question for running TimesTen in Client Server Mode. When it is running in Client/Server mode:
Does the database just run like a regular remote database ?
Is there security for the remote application, such as userid/password ?
Is there any limitation on number of remote connection can concurrently connect to the DB ?
Does it use the JDBC or it has to be the native library ?
Thank you for your help
Henry

Hi,
With regard to your questions regarding TimesTen client/server mode:
1. Does the database just run like a regular remote database ?
I'm not sure exactly what you are getting at here but yes, I would say that it runs like any other c/s database. If you can be more specific in your question then I can give a more precise answer.
2. Is there security for the remote application, such as userid/password ?
If the TimesTen instance to which you are connecting was installed with Access Control enabled then yes, normal userid/password security applies. The client application must provide a valid TimesTen userid and password in order to establish a connection.
3. Is there any limitation on number of remote connection can concurrently connect to the DB ?
Subject to O/S resource limitations, a single instance of TimesTen (i.e. the TT server) supports a maximum of 9,999 concurrent client/server connections. Each individual datastore supports a maximum of 2047 concurrent connections (direct and client/server).
4. Does it use the JDBC or it has to be the native library ?
The TimesTen JDBC driver supports both direct modde and client/server. The TimesTen ODBC driver is provided in both direct mode and client/server versions. The JDBC driver uses the ODBC driver (it is a type 2 JDBC driver) and so the client machine requires a TimesTen client installation to use either ODBC or JDBC to access a remote datastore.

WARNING - Oracle intends to desupport Forms client server mode

When Forms 6i becomes desupported you will have to move to Forms 9i. Forms 9i runtime can only be run in web mode from a web browser. You will not be able to run client-server forms in native operating systems such as Windows or Unix. The forms will essentially run on the application server with Java applets to being sent to your web browser. Links to third party products will no longer work with host commands executing on your local machine. You will have to include Java code to make local commands work.
The transition from Forms 6i client-server to Forms 9i web mode will be one of the most painful upgrades Oracle has ever inflicted on its customers.
Essentially, Oracle is trying to palm us off with running forms from web browsers whether we or our customers like it or not. Java seems to be creeping in. I suspect Developer will eventually turn into JDeveloper, as they will not want to support two products. Easy one line statements and built-ins will be replaced by hundreds of lines of Java nonsense. Developer will move from a 4GL RAD environment to a cumbersome bloated 3GL Java environment.
You can stop this happening if you want to keep you customers happy by:
1. Sending Oracle enhancement requests to allow Forms 9i to run in native client-server mode.
2. Complaining to your Oracle sales contact.
3. Asking difficult questions at Oracle user groups.

Duncan et al.,
I've been wondering why exactly a Forms9i app. needs to run in a web page? Why could the applet not be deployed in a more "standalone" fashion, i.e., an independent application window. This would at least offer the appearance of a native application, complete with the new Java look-and-feel.
If Oracle really wanted make their customers happy, they would then take the next step and come up with a way to embed OC4J into a client-side deployment executable, which would then effectively allow for a 2-tier client-server architecture.
It seems to me that 2-tier/3-tier each have their place in the world, depending on the situation. In the extreme "2-tier" example would be an application that is to be deployed on a single client workstation. It would be hard to argue that a separate application server ought to be used. On the other extreme, anybody who has tried to manage the deployment--and upgrade--of a large number of Forms clients is very attracted to the prospect of only having to maintain and upgrade a few application servers.
I agree with the direction of the product as far as replacing Toolkit2 and the native runtime with the JRE. The advantage of on-demand updating of application code is compelling. The capability of moving application logic to the middle tier is extremely useful. Platform independence is now done using the "universal" JRE instead of TK2.
If the product could maintain the client-side processing capability--without resorting to Javabeans--it would be just that much stronger. As an application architect, I want to be able to design the application to allocate the work where it makes the most sense, either on the client, the application server, or the database server.
How hard would it be to put this client-side processing capability back into the product?

Bruce MacDonald

Why timesten is slow in client/server mode

i am testing Timesten client/server mode and find that
it is to slow.
when using dircet mode, timesten can precoss about 40000 query pre second
but when change to client/ server mode
it can only process 1500 query pre second.
here is my config and test sql.
[Test_tt702]
Driver=//u01/oracle/TimesTen/tt70/lib/libtten.a
DataStore=//u01/oracle/TimesTen/tt70/info/DemoDataStore/Test_tt702
DatabaseCharacterSet=US7ASCII
TempSize=64
PermSize=250
Temporary=1
TypeMode=1
CREATE TABLE TEST999
A1 number NOT NULL PRIMARY KEY ,
A2 number,
A3 number
network card is 1000m,
query code:
PreparedStatement pSel = dbConn.prepareStatement("select a1,a2 from TEST999 where a1=?");
rs = null;
int a1=0;
int a2=0;
for(int i=0;i<80000 ;i++)
     pSel.setInt(1,i );
rs=pSel.executeQuery( );
if (rs.next()) {
     a1 = rs.getInt(1);
     a2 = rs.getInt(2);
     if( i%8000==0) {
     System.out.println("select "+ i +" res="+a1 +" time " + getTime_v2());
     rs.close();
direct mode time : 80000 query is 2 second
client/server mode in the same machine : 80000 query is 12 second
client/server mode in the different machine : 80000 query is 54 second
any one have idea about this?
is it the jdbc driver 's promble?

it is to be expected that there will be a big difference in performance between direct mode and client/server due to much greater overhead in client/server, especially if the client is on a different machine. However, the differences you are seeing here are larger than I would normally expect.
You say (I think) that the network is 1 GB, correct? What is the hardware spec of the test machine(s)? Have you tuned the O/S network stack for optimal performance?
Typically, for local client/server using the fastest IPC mode (shmipc) I expect performance of around 20-30% of direct mode and for remote client/server with a GB LAN I would expect performance of around 10-20% of direct mode.

D2k in client server mode & web environment

Hi friends,
I am using forms 6i with oracle 9i. I have a couple of questions, please advice.
I have developed couple of forms in client server mode and this would be added to an existing application. I have been informed now that the application is web based. I have no idea about how a form can be coded_for or deployed_in web based environment.
Is there any provision to convert the forms developed in client server mode so that we can use it in web based application ?
what is the effort required in doing this conversion ?
Do we have any docs for using d2k forms in a web environment ?
Plz feel free to point out if I have missed any detail without which it is difficult to answer this question.
Thanks

Hello,
It is very easy to migrate from C/S to web, because of the portabilty of the Forms design code (.fmb)
All you have to do, is to recompile the modules with the new binaries. The only "but" is that some instructions have been depreciated, and you have to rewrite them (often client machine interactions, that are covered by the Webutil library).
goto the OTN Forms home page, then click the Migration link.

Help-Is 9ias a necessity even for client server deployment of forms6i

Hi
Is 9Ias a necessity even for client server deployment of forms6i using developerSuite. I have been told that Oracle no longer markets Forms Server?
Ganesh.

No for client server deployment you don't need iAS.
On the second issue Forms server (the bit of forms used to web deploy) is no longer sold stand-alone - it is part of the iAS suite.

Can i use forms 9i for client server applicaitons

Hi,
I have to build a client/server application.Right now, we are using oracle 9i and developer suite 10g. In one of the articles on OTN, it says that from forms 9i onwards, it's not supporting client/server model. Do i have to use 6i for this.
Thank you.
Sree.

The last Forms version that can be run in c/s mode is 6i.

Oracle 9i Forms in Client/Server Mode (Updates in Technical FAQ)

Hi All,
I'm doing an investigation for porting to Oracle Forms 9i and I've found the answers in Oracle 9i Forms Technical FAQ of February 2003. But since it's been more than three and a half years, I would like to know if the following information in the FAQ still holds?
Upgrading to 9i
What versions of Forms can I upgrade to Oracle9i Forms?
Only Forms 6.0 and Forms 6i are supported for direct upgrade to Oracle9i Forms. Older versions of Forms should be upgraded to Forms 6i first.
Can I run Client Server or Character Mode applications in Oracle9i Forms?
No. Oracle9i Forms only supports Web deployment. Applications that need to be run in Client Server or Character Mode should remain in Forms 6i. Forms 6i will be supported until December 31st, 2004, or December 31st, 2007 with Extended Support for customers who wish to maintain such applications.
What changes will I have to make to my application before upgrading?
Many Client Server and Character Mode features have been removed from the Forms product for 9i. The removed features mainly relate to features that where only maintained in Forms 6i for the purpose of backwards compatibility. A detailed list of all of the obsolete features can be found on OTN (/products/forms/pdf/featuresobsolescence.pdf)
Is there an easy way to find out if my modules use obsolete features?
Yes. Oracle supply a separate utility with the Oracle9i Forms distribution "f90plsqlconv". This is a utility which will scan your files for obsolete usages and correct them where applicable. It will also alert you to any changes you may have to make manually.

As far as I know it still holds: Forms9i isn't changed since then.
What I don't see in the FAQs is if you move form client/server to the web that you must be aware that the forms are running on the application server instead of the client PC. So calls to TEXT_IO and HOST etc are also executed on the appserver. You should review those calls and decide were you want to have them executed...(use webutil if you want to keep the execution on the client)

Best practice for client-server(Socket) application

I want to build a client-server application
1) On startup.. client creates connection to Server and keeps reading data from server
2) Server keeps on sending different messages
3) Based on messages(Async) from server client view has to be changed
I tried different cases ended up facing IllegalStateChangeException while updating GUI
So what is the best way to do this?
Please give a working example .
Thanks,
Vijay

Hi EJP,
Thanks for the suggestion ,
Here is sample code :
public class Lobby implements LobbyModelsChangeListener{
    Stage stage;
    ListView<String> listView;
    ObservableList ol;
     public Lobby(Stage primaryStage) {
        stage = primaryStage;
           ProxyServer.startReadFromServer();//Connects to Socket Server
         ProxyServer.addLobbyModelChangeListener(this);//So that any data from server is fetched to Lobby
        init();
    private void init() {
          ProxyServer.getLobbyList();//Send
        ol = FXCollections.observableArrayList(
          "Loading Data..."
        ol.addListener(new ListChangeListener(){
            @Override
            public void onChanged(Change change) {
                listView.setItems(ol);
     Group root = new Group();
    stage.setScene(new Scene(root));
     listView = new ListView<String>();
    listView.maxWidth(stage.getWidth());
     listView.setItems(ol);
     listView.getSelectionModel().setSelectionMode(SelectionMode.SINGLE);
    istView.setOnMouseClicked(new EventHandler<MouseEvent>(){
            @Override
            public void handle(MouseEvent t) {
//                ListView lv = (ListView) t.getSource();
                new NewPage(stage);
     root.getChildren().add(listView);
     @Override
    public void updateLobby(LobbyListModel[] changes) {
//        listView.getItems().clear();
        String[] ar = new String[changes.length];
        for(int i=0;i<changes.length;i++)
            if(changes!=null)
System.out.println(changes[i].getName());
ar[i] = changes[i].getName();
ol.addAll(ar);
ProxyServer.javaProxyServer
//Implements runnable
public void run()
     ......//code to read data from server
//make array of LobbyListModel[] ltm based on data from server
     fireLobbyModelChangeEvent(ltm);
void addLobbyModelChangeListener(LobbyModelsChangeListener aThis) {
this.lobbyModelsChangeListener = aThis;
     private void fireLobbyModelChangeEvent(LobbyListModel[] changes) {
LobbyModelsChangeListener listner
= (LobbyModelsChangeListener) lobbyModelsChangeListener;
listner.updateLobby(changes);
Exception :
java.lang.IllegalStateException: Not on FX application thread; currentThread = Thread-5
         at line         ol.addAll(ar);
But ListView is getting updated with new data...so not sure if its right way to proceed...

Can i use forms 9i or 10g for client/server applications

Right now, we are using oracle 9i DB and developer suite 10g. I have to build a client/server application. In one of the OTN articles, it says that from forms 9i onwards, it's not supporting client/server applications. Do i have to use 6i for this.
Thank You.
Sree.

That's right. Only web deployment is support from 9i onwards. Bad decision since Oracle seems to ignore their customer's view

Developer 6.0 - Client/server mode

Assuming I have an application server between the front and back ends, what needs to be running in the middle tier, if I am running strictly client/server ?

It's, first, a problem of client power. On 3 tier, the client needs to do nothing else except run the web browser; the PL/SQL code in forms/reports running on the application server. So, a 3rd tier client might be even an old 486, while a pure client-server would have to be Pentium, preferably 64 MB RAM, have enough disk space for the application and have Forms & Reports runtime installed.
Then, there is a matter of network communication: an application server could accomodate more clients than classic client-server.

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.

Tips for Client-Server project please...

I've written a few Java apps (some very simple, some not quite so simple) so far and I think I'm ready to begin tackling my big goal. I want to create a distributable client desktop application that will actually be very simple in functionality. I want the clients to be able to connect to a server (that I will also be creating) for authentication and then allow automated messages to be sent to other clients also connected to the network. I'd like any links to tutorials, libraries, and anything else that would help point me in the right direction. Thanks!

Actually, if you're on about clients sending messages to each other, then you're not really talking about client-server apps at all. You're veering off into JMS territory, maybe even ESB territory(but probably not). Have a butchers at ActiveMQ, and Camel, both from Apache, for that.
Either way, I wouldn't bother creating your own server, just use an existing one. Jetty's nice and lightweight, and easy to embed. You're about to say "I'd rather create my own" but it's a bothersome task that people far more skilled than you (and me, before you take offence) have already done much better than you ever will. Take advantage of that fact, and concentrate on the specifics of your own app.
