INTEGRATE EPOS PRINTER TO SWING APPS

EPOS APPLICATION
I have a swing retail application.
I want to integrate EPOS(Electronic point of sale) printer and cashdrawer
with the application. I need a manufacturer/Sun partner that have printer and cashdrawer with pure Java
driver that can easily be integrated into Sun Java 2 Runtime Environment 1.4 and Java 2 SDK SE v1.41._01
environment. Any idea?

I added what I knew about improving Sun java fonts to the wiki: http://wiki.archlinux.org/index.php/Jav … _-_Sun_JRE. You may want to try other fonts than B&H's Lucida. See the section in the wiki article about changing the default fonts by editing 'fontconfig.properties'.

My Swing app (JRE 1.5.0_12-b04) is crashing while invoking print apis ..

My Swing app is crashing each time when the print apis are invoked. This is happening only on a particular box. We are able to print from other apps on the same box.
Any pointers on whats going on? Thanks in advance.

How to create printable report from a swing app.

Hi,
I have googled quite a bit and have searched the forum extensively but haven't found answers to my questions.
I have a small swing based application (that uses jtextfields, jbuttons, jlist, etc) that collects information from user
and stores in some variables; which are like strings, integers, hashmap, etc.
Now this information is to be formatted and is to be printed as a report.
Formatted as in, some part of the collected text is to be printed in certain font and other in different color and so on.
Also the report is to be printed on a paper leaving some space at left and at the top. That means margins need to be set.
And before all info is to be sent to printer I need to display this information in some report viewer (preview).
How can I format certain text and set margins? (Is there some Document kind of api which allows me to set margins, change font of certain text?)
How should I display this text / information as a print preview? (Should I use jeditorpane / jtextpane ?)
How should I send all the information to the printer? (What java api should be used for printing?)
The data entered by the user is not saved / persisted to any database. It's to be sent to the printer after submit button is pressed on the swing app.
Since there is no database I couldn't use jasper-reports.
Following are links to all threads (not useful) I found when I searched for swing / print / report in the forum :

Alan Mehio,
I have been able to set margins and get the printout just the way I want it (after some experiments / trial & error).
But the problem is, parameters to paper.setImageableArea() are hard coded as in the example code below :
        System.out.println("print?");
        PrinterJob printJob = PrinterJob.getPrinterJob();
        if (printJob.printDialog()) {
            PageFormat pf = printJob.defaultPage();
            Paper paper = pf.getPaper();
            paper.setSize(8.5 * 72, 11 * 72);
            System.out.println("paper width : " + paper.getWidth());// expecting 612
            System.out.println("paper height : " + paper.getHeight());// expecting 792
            System.out.println("ImageableHeight : " + paper.getImageableHeight());
            System.out.println("imageable width : " + paper.getImageableWidth());
            System.out.println("ImageableX : " + paper.getImageableX());
            System.out.println("Imageable y : " + paper.getImageableY());
            //paper.setImageableArea(108, 144, paper.getWidth() - 108, paper.getHeight() - 144);
            paper.setImageableArea(222, 244, paper.getWidth() - 222, paper.getHeight() - 244);
            pf.setPaper(paper);
            printJob.setPrintable(jTextArea1.getPrintable(null, null), pf);
            try {
                printJob.print();
            } catch (Exception ex) {
                System.out.println("exception while printing...");
                ex.printStackTrace();
        }In my case the left margin should be 1.5 inches (38.1mm) and top margin should be 2 inches (50.8 mm)
Considering 72dpi printer for a A4 size page (8.5in X 11in), the parameters to paper.setImageableArea() should be
(108, 144, paper.getWidth() - 108, paper.getHeight() - 144);
But the printout leaves only 1inch for top and left margins.
Here are o/p lines for method-call with above said params :
paper width : 612.0
paper height : 792.0
ImageableHeight : 648.0
imageable width : 468.0
ImageableX : 72.0
Imageable y : 72.0
When I pass the following values I get text printed with desired margins on the paper but the above printlns remain exactly the same!
paper.setImageableArea(222.4, 244, paper.getWidth() - 222.4, paper.getHeight() - 244);
Although I have been able to achieve what I wanted to without using 3rd party libraries,
I feel this hard coding of values isn't a good idea and leaves a doubt whether this will work on other systems with different printers.
My question is, how to get these numbers correct every time? Is there a formula for obtaining these numbers?
Also formatting of certain part of to-print text is something that is yet to be figured out.
Thanks.

JAVA / SWING apps, font AA / LaF KDE 4.3

Hi Everyone,
I know the title is terrible, but here is my problem:
I am using Netbeans for most of my development projects. I am very happy with it; however, the look and feel of Netbeans (and most other Java apps, such as FreeMind for example) is appalling and does not integrate into my KDE 4.3 desktop at all. I understand that you can start netbeans with certain options to change the look and feel to GTK, but the fonts still look jagged.
I followed this forum post http://bbs.archlinux.org/viewtopic.php?id=72892 and tried to set the JRE / JAVA options globally, so that all java apps start with GTK laf and AA. However, non of the methods described work / netbeans overrides them (?).
But really, the biggest problem are the ugly fonts. Java / SWING apps do not seem to recognize my KDE settings for AA and font style at all. And non of the Cl options work to fix it.
Does anyone have any tips or tricks to fix any of these issues I am having with the combination Java / Swing / KDE / NB?
Running:
Archlinux (duh)
KDE 4.3 / qt-gtk-engine
sun-jdk 1.6uX
Netbeans 6.7.1
Thanks!
KnY

Hi @EslamHassan
Welcome to the HP Support Forums. I gather that you have a question regarding the HP All-in-One Printer Remote app.
The LaserJet M127fw printer is not a supported printer for the HP AiO app. I have included the HP Printers and Supported Mobile Printing Solutions document for reference.

Major Printing Problem - Can't Print in any App, with Any Printers

I help my Aunt with her three Macs (2 eMacs, 1 MacBook, all running 10.4.8 right now) at her office, and she had me come to help recently because one of the eMacs stopped printing anything; here's what happens:
In every app besides Word (e.g. Safari, TextEdit, AppleWorks, etc.): If I click File>Print... or press 'Command-P,' the cursor turns into the spinning rainbow for a few seconds, and nothing happens (meaning I can do anything I want in the application, as if nothing at all happened).
In Word: If I click File>Print... or press 'Command-P,' Word sits for a minute with the spinning rainbow, then locks up and quits itself. BUT, if I click the little 'print' button in the toolbar (the one that bypasses the print dialog box), the file will print.
I tried resetting the printing system, setting up different printers on the computer, printing over the network and over USB (directly connected to port 1 on the eMac), and re-downloading/installing the printer drivers for the Brother 5250DN laser printer AND the HP LaserJet 1200 laser printer, but all to no avail.
I can run the Printer Setup Utility and recognize the printers (via Bonjour over the network and via USB), and the computer can run the printer setup utilities, so I know the printer communicates fine with the computer. I also can print to the printers (both the networked one and the Brother) from any of the other Macs (including my own laptop) over the network. But I can't get the print dialog box to show up for any printer on the one eMac.
I'm determined that this problem lies within the OSX printing system, but reinstalling the whole OS is not an option, as I would have to re-setup all the software, user accounts, special network settings, etc. (even if I do an Archive and Install). Is there anything I can do??? (I seem to recall someone else having this problem, but I can't find that thread on the forum).

There's another thread describing this same problem. I am having the issue too. As I posted in the other thread:
"Well, I did a full Archive and Install, with restore user settings, and the thing still won't print! All apps crash when trying to print (except Mail.app, which is odd). So it appears all of the files required for printing are there since Mail.app works, but I still can't print from Safari, Firefox, Preview, TextEdit, etc etc. ARGH!!!!
Next step is to downgrade to 10.4.8."
If that doesn't work, I guess an Erase and Install would be th next step.

Keyboard Problem while running Swing App on LINUX

Hi All,
We have a Swing based Application running on Windows Platform. We need to run the Application on LINUX. The Application does not have any problem and runs without problems for a few minutes but after that the keyboard stops to respond inside the application. Keyboard runs fine outside the application but no key events are recognized inside the application. Mouse is working fine even after the keyboard stops responding.
Key Points:
�     The keyboard is a PS/2 keyboard.
�     Read Hat Fedora 5.0 is being used.
�     The problems occur on both KDE and GNONE.
�     The Java Version is jdk1.5.0_09
The application is data entry application using EJB at server side. The client UI has lot of JTables and Desktop Panes/ Internal Frames. User use ctrl+tab, ctrl+shift+tab, tab, shift+tab, and other hot keys to navigate between Components. Listeners on keyboard Focus Owner are also used. We are unable to diagnose the problem because of the undeterminable nature of the problem. The problem occurs at anytime and does not occur on any special key/ combinations press.

I've just installed the JDK 1.4 on my debian box. I
can compile and run a basic Hello World app using
System.println, but when I try to run a simple swing
app, I get an error like:
Exception in thread "main"
java.lang.NoClassDefFoundError
at java.lang.Class.forName0(Native Method)
at java.lang.... etc, etc.
It goes on with about 30 different classes. It
compiles fine, with no errors, but when it comes time
to run, that's what I get. This is what I have in my
.bash_profile as far as environment variables go:
export JAVA_HOME="/usr/local/j2sdk1.4.1_01"
export PATH="$JAVA_HOME/BIN:$PATH"
export
CLASSPATH="$JAVA_HOME/jre/lib/:$JAVA_HOME/lib:."The code works fine in Windows, so unless there's
something platform-specific, I don't think there's a
problem there. I've checked to make sure I'm not
running kaffe by accident and I'm definitely running
the right java and javac. I'm out of ideas. Any
suggestions would be greatly appreciated.
-dudley
I may just be crazy, but your PATH looks a little screwy to me. I was under the impression that the standard java installation has its executables in the 'bin' directory, not the 'BIN' directory. Unless Debian has fallen to the evil empire, then I'm fairly sure file names are case-sensitive. I don't know if that will fix your problem though. Do you compile from the command line, or do you use an IDE???

Yes, good question, on my remote app it is very slow too....

Launching Swing apps in foreground remotely

We have an agent that runs on our machines waiting to start and stop java applications, but there is a problem when the application has a GUI element to it. We are using the RunTime classes and it executes applications in the background which means that GUIs cannot be seen even though they are running.
What is the secret to automatically launching java swing apps in the foreground?
Thanks in advance.

Replying to myself, as I think I've just found the answer (at least for an windows environment)
--> Just start your app with "javaw" instead of "java"
(What would be the right way to do it in Linux, for instance?)

Swing app keyboard stops working, mystery ESCAPE keystrokes appear in EDT

Java 6 Swing app. In our development environment, works great. In QA, they use it for a bit, type in a text field, click out to a Windows XP/7 app, click back in the text field, and the keyboard stops accepting keystrokes. The mouse continues to work, and the Swing app continues to paint to the screen.
I hooked up a KeyEventDispatcher to listen to what is going on. I'll post a more verbose log at the end of this post, but the short version is this. When the keyboard hangs, the log shows that 'escape' keys are being sent, though we do not do any keystroke injection in our app, ESCAPE or otherwise. Nothing on the Swing app can be determined visually to have focus.
Just before the app starts hanging, it has a side effect of not being able to be brought into the foreground by clicking on it, if, for example, one was working with Excel or Notepad, then try to click on the JFrame title of the app, or anywhere else on the app frame/internals. Once this condition happens, moving away to another Windows app, then going back to the Swing app, causes the keyboard to stop working and the KeyEventDispatcher to see 'escape' keystrokes being sent out.
Connecting remotely to the app via JVisualVM/JConsole does not show any of the threads hanging/blocked.
Sometimes you can work for hours before seeing this problem, and other times, you can start the app up and it happens right away. Once it happens, sometimes you can't recover, and sometimes you can click on a button on a navigator panel on the left side that displays an info panel on the right side, and you can start typing again in text fields.
Once this problem happens, you can start (or have already running) a completely different Swing app (ex.: StackTrace), and the keyboard will stop working for that app too, even though its running in its own separate VM.
This problem (ALMOST!) always happen when typing in a Swing text field (JTextField, JTextArea, etc.), clicking on and then typing in a Windows text area (Excel cell, Notepad), then clicking back into the Swing app's text field. A few times, we've gotten this to happen by typing in a text field, tabbing to a button, pressing a button, then tabbing/clicking back into the text field, all without leaving the Swing app. But this latter scenario is rare, usually going to/from Swing/Windows XP/7 apps cause the problem to occur more readily.
The QA computers normally use Citrix to connect and run the app, but this also happens if we run the app completely locally. But again, this only happens to some computers, all of the ones in the QA department; the development computers (the app has not been released into production yet) does not see this problem.
I had thought that our problem was this problem (Wrong characters in KeyEvents generated from input of barcode scanner but purposely slowing down the acceptance of KEY_PRESSED and KEY_RELEASED events before allowing them to go on to the Swing app (via a KeyDispatcher) did not solve the problem.
Also, we had thought it might be a Citrix problem and how it (or does it?) hook into the Windows keyboard. The fact that once one Swing app gets into this keyboard doesn't work and escape keys are being sent out by the EDT can affect another Swing app makes me wonder. We're not seeing any VM exceptions either like this (EXCEPTION_ACCESS_VIOLATION - JRE 6.0_23 - Citrix, windows 2003
Been trying to get this one solved for over a week, but with no luck. Any help/advice would be appreciated. Thank you in advance for your time.

The above log info repeats multiple times, KEY_PRESSED and KEY_RELEASE, over and over again, for 'escape' keys.

<discaimer>Don't put too much hope in my reply</disclaimer>
The only real difference is QA has the Citrix client installed on them, and development does not. You don't need to run our Swing app through a Citrix client though to cause the bug/freezing, just running it on a PC with the Citrix client seems to be enough (in theory). We've been working down a checklist of possible problems/solutions, and we've gotten to the "Install Citrix to the dev PC" item now, so I'll post back if that makes a difference or not in reproducing the problem.
I've also had QA people actually come over to a dev PC, without the Citrix client, and try to reproduce the problem, and they have not been able to. There's 'something' about their environment vs. ours, but not sure how that would manifest itself as a AWT/Swing keyboard event of mysterious escape keystrokes followed by the locking up on the keyboard, but not the whole Swing app. My personal guess is the Citirix client installing funky Windows-level keyboard driver(s), but I may be totally off on that. /shrugI read your initial post twice and couldn't find out whether you reproduce that on several different machines, so one "environmental" difference comes to mind: have you tried using another keyboard on the defective QA configuration?
Of course that doesn't explain in itself how the problem would manifest only after switching back and forth to a native Windows app, but then, with the hint that Citrix may make a difference, maybe one driver filters out repeated "Esc" keystrokes, while another doesn't, and that manifests only after a few app switches, and the system event queue, or whatever it's called in Windows, redirects the events to the target app/window?
Other than that, I wish you had investigated Jeanette's pacemaker hypothesis more... ;)
Otherwise, yeah. I have a hook in to see all AWTEvent's, but I still need to see/find what's posting the mysterious escape keys to the event queue.I assume it's what you mean, but I'll try to make that clear: you have to investigate, at the OS level, what is posting escape key events to the OS queue.
I am not a Windows developper, but I seem to understand that the following programs claims to capture keystrokes on the whole screen (not limited to a single window), with some limitations: http://www.codeproject.com/KB/winsdk/WIN_RECORDER.aspx
More generally, you should search for a Windows way to peek at the Windows' (keyboard?) event queue.
I'm not sure this could identify which DLL (if it's not originated by the material, see the defective keyboard hypothesis) is posting the events, but that's worth a try (Java for example, would enables to stuff a custom event queue that would trace info about a Java-poster).
Even if you can't identify the posting DLL, running the "key captuyre" on both the Windows host that has the Citrix window, and the Windows host that you are accessing via Citrix, may give you hints as to where the heck the key strokes originate...
Good luck, and keep us informed,
J.

Which adapter to use to integrate 2 instances of oracle apps 11.5.10

We are using Oracle application server 10g integration interconnect(iSTUDIO) to integrate two instances in oracle apps 11.5.10 for the purpose of implementing customer data hub. We are not sure which adapters to use for this pupose. Whether it will be
1. database adapters
2. oracle application adapter
3. Or any other adapters.
We have to use publish/subscribe messaging paradigm.
Any kind of help is welcome

Sourav Biswas

Soubi,
Yan is right but to add a bit more.
Consider 2 application instances APP1 and APP2.
If you install an OA (Oracle Apps) adapter into an OracleAS Oracle Home and point to APP1, you must use copyAdapter to "clone" another adapter of the same type (e.g. another OA adapter) for APP2. I don't think the copyAdapter script runs any of the post installation steps either so, you'll have to run the OAI schema scripts to create the OAI schema on APP2. See the post_installation.txt file for more information. This is in the adapter home directory.
If you install an OA adapter for APP1 and decide to install a DB adapter for APP2, you can use the installation media to install both.
However, if you decide (for whatever reason) to install an OA adapter and a DB adapter for APP1, you should be aware that the installation of the second adapter will drop and recreate the OAI schema for the spoke database. If you have been using one of the adapters before the second install this may cause you problems.
Regards,
David

You can use:
1) database adapter (to publish from OEBS you call PL/SQL(send), on subscribe the PL/SQL(receive) called by adapter)
2) AQ adapter (to publish from OEBS you put message in outcome queue, on subscribe the message is put in income queue by adapter, you listen inbound queue in APPS)
3) Oracle Applications Adapter - it realises two above paradigms!
It can interact as 1) and as 2)
With one - you select in iStudio when you create Publish or Subsribe!

Swing app in JDK6 continues to rendering slow in Windows Terminal Server

Hi,
Because Swing apps create interfaces internally and not using default OS APIs,
when running into a Windows Terminal Server client, there is no way to optimize
rendering. Windows Terminal Server and Linux FreeNX use a mechanism to send
to client only commands to render the windows. But, because the way Swing works,
not totally integrated to OS APIs, it's not possible for terminal servers to do this,
and these servers render Swing like images, something like VNC do, very slower than.
I have tested native apps and AWT apps, and the difference is very significant,
something like 50-70% faster.
Is there some project in Swing APIs or java.net open-sources to better this?

We are also seeing this issue with a Compiere implementation. With 10 distributed sites across the US, our client wanted to use Windows Terminal Services to simplify the client desktop management of the Swing application.
But performance is terrible...and screen painting issues a real problem. We are also on JDK5 still, so I'm discouraged to see that JDK6 doesn't appear to offer much improvement?
Is there any project afoot to address this issue for installations using terminal services?
Thanks,
Peter
