Java gui apps look garbled/distorted?

Hi,
I'm using Java v 1.5 in Windows XP Home and Java apps look garbled (JEdit, exe4j and my own apps). In Linux everything looks normal. Is this a know problem? Any suggestions?
Thanks!

Hi,
The problem is that I get this in all apps using the JVM. That is, not just my own apps, but also the Netbeans IDE, JEdit, J4exe etc. I uploaded some screenshots to this location:

Both text and window frames look garbled/distorted. For instance, look at the file menu.
Thanks

All java GUI apps suddenly never repaint

This isn't really a programming question, but I've had a hell of a time finding help resources elsewhere (Sun's got the balls to charge money for the support document that will most likely help me!). Does anyone know anything about what might cause all Java GUI apps to never repaint? I just installed the Java 1.5 update 4 JRE & JDK, I'm running Windows XP SP2, and I have dual monitors, although turning the second one off (via the control panel) doesn't seem to help.
Neither my own software nor commercial software will work (even NetBeans). They all load an empty JFrame, or paint themselves once and never again. Console apps seem to work just fine, though. If anyone knows how to fix this, has any suggestions on what I should try, or can tell me where to look for a solution, I'd be very grateful.
Thanks,
Tim

I appreciate the help, and maybe I'm not following you, but this is happening for ALL Java GUI apps, even NetBeans itself won't repaint. Not sure how I have control over NetBeans's UI thread?
Thanks

Java GUI apps not working

All my Java apps are not rendering their GUI properly anymore. It seems to affect those that are using a Carbon-ized UI. I'm guessing this means all Swing apps?
Regardless I'm trying to figure out a way to fix this without re-installing the OS...
Any tips?
thanks in advance.

Have you tried deleting the Java caches? Close all your Java applications first. You'll find some in <user>:Library:Caches:Java Applets. While you're there you can also clean up anything else in the Caches folder that might be related - it's not a problem to remove anything in here, they'll just get recreated and may cause the related application to start up a bit slower next time.
There should also be one or more 'Plugin Settings' files in the Applications:Utilities:Java (note: I'm on 10.3.9 and this may be different for you - I have two: one for 1.3.1 and one for 1.4.2). Launch them and use whatever features they have for cleaning up unwanted caches/mess, but I think they just remove the cache files I mentioned in the first paragraph.

GUI Scripting Java SWT apps

Hi,
It doesn't appear that the GUI scripting works with Java SWT apps (eclipse, etc). Is there any way to get this to work?
Thanks,
George

Explorer it with PreFab UIBrowser see if it got any GUI element, if not out of luck. I don't have any Java SWT so I have no way to test my idea. But that where I would start.

Deploying Java Desktop App using executable JAR files

Hi there.
Today I am very optimistic about java. I am a beginner, and I had tried (in my few free time) to understand how to deploy java desktop apps.
I am using the lattest NetBeans IDE to do the programming and it is very very fast and optimized.
Going to the point, I tried some time ago to deploy an application (made with this IDE) using JAR files, but even though the application run well on my IDE, when I packed it, it rised an error saying that
java.lang.NoClassDefFoundError: org/netbeans/lib/awtextra/AbsoluteLayout
I was using an absolute layout on my JFrame forms and this AbsoluteLayout is provided by netbeans and not by the normal SDK.
I then looked for the absolute layout class and found a jar file in the following path:
C:\netbeans\modules\ext\AbsoluteLayout.jar
So I mounted the Jar file in my File Systems and then added the contents of the file to myApp.Jar file.
I used the automated Jar Recipe Packaging feature of netbeans, that is why I needed to mount the AbsoluteLayout.jar file into my file systems.
Now it runs fine by just right clicking the MyApp.jar file from Windows Explorer.
In a next reply to this topic I will include some sample code so that anybody requiring to do such implementation can take this for help.
Regards!
JN

Well,
I will take some time here to show the basic source code and procedure to create a desktop application, pack it up in a Jar file for deployment, add other classes or jars to the deployment jar file and finally open the jar file as an executable. This applies for either windows and linux environments.
Take in count i am using Netbeans IDE 3.x (3.5)
First I open the IDE and create a new project called MyDesktopApp. This is done by going to the menu Project / Project Manager. Then click on the New button and specify the project name and click on OK.
At this point, the Filesystems tab in the project explorer is empty. So I mount a directory to store myDesktopApp in it. I selected c:\MyDesktopApp but you can select any name you want.
To mount the directory you follow these steps:
1. Right-click on File Systems
2. From the contextual menu select Mount > Local Directory
3. In the filechooser window, you just browse it and SELECT the directory to mount. Be aware that you can even create the directory on this window. Do not enter (double-click) into the directory you want to mount, just select it and click on finish...
4.Then the directory entry appears under the filesystems node of the project explorer.
Now you have to create your application. You can either create a package (special configured and tracked directory) or you can create the clases directly inside the directory. For tidy project, I will create the package.
To create the package follow these instructions:
1. Right-click on the mounted directory and from the contextual menu select New > Java Package
2. In the New Wizard - Java Package window, type the package name and click on finish. I use the "MyDesktopApp" as package name.
OK. Now the package is created under the mounted directory. Now we have to create the Main Class. In this case I will use a JFRAME as the main class but you can create any class you want.
To create the JFRAME as main class follow these steps:
1. Right click on the java package you just created and select New>JFRAME from the contextual menu. If you do not see the JFRAME option on the NEW sub menu you will have to select the All Templates option. I explain the All Templates option now on, it will be easier to use the JFRAME if available. Once you use JFRAME with the all templates then the JFRAME will show up in further NEW usage.
2. So finally we used the All Templates, and you select the Java GUI Forms > JFRAME form option and click on NEXT.
3. Give it a name. (I used MyDesktopAppFrm) and click on finish. Be aware you can set advanced options by clicking on next. But for the purposes of this topic we will use default options so click on FINISH
4. A new JFRAME form appears inside your package. Right click on the form and select Set layout > Absolute Layout.
5. Add some controls and code. I added a label and a button. And coded the ActionPerformed event of the button to say hello! on the label. this is up to you. The code just looks as follows:
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
// Add your handling code here:
jLabel1.setText("Hello folks!");
6. Compile and execute the form.
Let's say this is our Desktop Application. Now We will pack it in a Jar in two steps...
A. Create a JAR file (Recipe)
1. Right-click on your package and select New > All Tempaltes (Long Route) You can also select New > JAR Recipe if available.
2. On the New Wizard Window, choose the JAR ARchives > JAR Recipe template and click on NEXT
3. I used MyDesktopApp as the file name and Defaults and then click on Next.
4. Specify the JAR Contents. Select the Package (not the mounted folder) from the mounted file system and click on add and then click on NEXT twice...
5. On the JAR Manifest window, click on GENERATE
6. Edit the manifest in the window to add the following code:
Main-Class: MyDesktopApp.MyDesktopAppFrm
7. Ensure the Main-Class definition is the same as your java package and JFRAME name. Click on FINISH
8. At this point we have a jar file in your project directory but this file wont run because it is missing some Netbeans clases that we will add in the next set of steps... Just to check, compile the file (right click on the JAR file and compile) and try to execute. It must compile but must not execute.(well if it executes you are done. It may execute if you did not set the lay out of the form as AbsoluteLayout)
B. Add the AbsoluteLayOut to the JAR
1. Right click on File Systems and select Mount > Archive Files
2. Look for your netbeans installation folder and select the following file:
.../netbeans/modules/ext/AbsoluteLayout.jar
3. Click on finish
4. Now the JAR File is mounted in the file systems.
5. Right-click on your MyDesktopApp.JAR file and select properties.
6. Look for the contents property click once on it and then on its elipsis button [...]
7. From the FileSystems box in the Contents window, select the AbsoluteLayOut file and click on Add
8. Then the system asks you if you are sure. Of course you are so click OK. (If not sure, just read the message text and click OK...:-))
9. Click on OK
10. Compile your JAR Recipe (right click on it and Compile)
11. Now you must be able to run the file by right clicking it and EXECUTE.
12. Also you must be able to run the file by double clicking the file from a Windows Explorer. You may receive a message asking to select the program to run the file with. You must browse and select the Javaw.exe file in the bin directory of your Java RUn Time installation. This is typically located at C:\j2sdk1.4.0_01\jre\bin or something like that. Use the File-Search feature of window to locate the JAVAW.exe file if needed.
I hope this long explanation helps somebody to deploy Java Desktop applications. Please reply the message if it helps you just to know it was useful.
Thanks for your time....

Modularizing large FX gui apps, esp. using fxml developed by Scene Builder

StarterApp - One large java source file.
Trying Out the JavaFX UI Controls (Using the JavaFX UI Controls)
StageCoach is a simpler app, but with fxml, controller, and main code in separate files.
Allows manipulation using Scene Builder.
https://code.google.com/p/jfxtras/source/browse/ProJavaFX/Chapter03/StageCoach?repo=samples&r=322042d9ac293fcd9dd8f63e1664df45a0c4746f
I was lead to these by the book, Pro JavaFX 8:
http://www.apress.com/9781430265740
Rich as it is, the StartApp is one big piece of code, with no modules such as an fxml file.
By spreading out the code for StarterApp and StageCoach and studying it carefully
I should be able to build a system as large as StarterApp, but as a three-file combo.
StarterApp has nothing that deals with concurrency or persistence - those will be my jobs.
I'm doing this because I'm building a large NLP app.
It needs a GUI for future users.
- Bob F

Take a look at some app examples from the open-jfx repository
https://wiki.openjdk.java.net/display/OpenJFX/Quick+Start
For a smallish app, see the ConferenceScheduleApp:
   openjfx/8u-dev/rt: 3d138300d935 /apps/experiments/ConferenceScheduleApp/
For a (much) larger app, see SceneBuilder:
   http://hg.openjdk.java.net/openjfx/8u-dev/rt/file/3d138300d935/apps/scenebuilder
   Ladstatt: Home made JavaFX SceneBuilder
For a minimal framework which features FXML and dependency injection, see afterburner.fx:
   http://afterburner.adam-bien.com
You can skip all of the stuff below if you don't like reading and just want to go code...
In general for app code, use aggregation over inheritance in most places, though inheritance is useful sometimes. Don't try to create your own controls by extending the Control class unless you are writing control libraries - that is complex and not well documented as well as largely unnecessary for app code. Similarly PopupWindow isn't all that great or at least I have never found a need for it in app code - a basic Stage works fine for pretty much every case except perhaps very specialized things like context menus. Java 8 has built-in dialogs and alerts in 8u40, so for standard dialogs or some reasonably customized dialogs, using those is better than creating your own. If the standard controls aren't enough, try ControlsFX, it is (mainly) great and high quality.
Let resizable layout managers do the layout work for you and use constraints in the layout managers and nodes rather than mucking around with fixed sized layouts or layout through binding.
Don't try to implement a spreadsheet in a JavaFX TableView - just use the built-in controls for what they are good at and either develop a new control for specific functionality not provided by the built-in controls or just skip that feature if it would be too expensive to build it from scratch yourself (and it probably will be expensive - you just have to justify that against your project budget whether that is money or your own time).
Make use of WebView to bring in web components (e.g. Google Docs or Google Maps). Don't try and pass a lot of data back and forth between a WebView and your app.
Don't do any style in code nor in FXML, put it all in a CSS style sheet.
For medium sized apps - use FXML to design and mark-up your GUI, and use SceneBuilder to create and edit the FXML, don't hand code basic form style UIs - in the long run the FXML based app will be easier to maintain.
For really small apps and learning tasks, write everything in code against the API so you understand that - use no FXML at all.
With JavaFX you are writing user interfaces, follow basic user interface design heuristics for which there are some principles to keep in mind.
Once you have a few FXML pages, passing parameters or sharing data between them is a question that most people run into as well as how to deal with navigation. That navigation framework I linked is super basic and just meant for pretty simple applications. A nicer framework which worked in general like a Browser navigation model would be useful - but I haven't seen a generic implementation of such a thing yet - I guess you could create one, but I definitely wouldn't start out trying to do that - instead focus on the basics of your application and get that implemented first. If you end up needing a reasonably sophisticated navigation framework, eventually you will know it and can evaluate what to do then.
You can do an awful lot with CSS and styling the built-in controls. It really is very flexible. Learn CSS and the JavaFX variant by reading general CSS tutorials (then forget everything HTML specific) and study in depth the JavaFX CSS reference guide and understand its extensions like looked up colors and derivation functions. When you want to know how some inbuilt thing is styled, go to the modena.css source (which can be hideously obtuse and complicated). Use ScenicView and SceneBuilder CSS analyzer to understand how CSS is applied to elements. Don't style borders with boxes - use layered backgrounds, that is how every control modena.css works and how your app should also work.
Deployment is a difficult topic - so sad and depressing. For development, just build and run in your IDE. For production, package the app as a self-contained application. Maybe one day there will be a better deployment model for JavaFX - but that is the best you can get for now. Completely ignore webstart and web deployment models - any time spent investigating such technologies is completely wasted.
Do not try to integrate JavaFX and Swing or SWT. Just write pure JavaFX apps.
For larger apps you intend to deploy to production, use Maven or Gradle as your build system (you can google the JavaFX plugins for each). Do not spend any time with the stand-alone JavaFX packager or the JavaFX ant tasks and do not rely on your IDE to do your production builds.
Get help to targeted questions on StackOverflow.
Only code to Java 8+ and make use of functional programming techniques.
Don't write multi-threaded apps unless you know what you are doing. When you do write multi-threaded apps, use the JavaFX concurrency utilities. Never modify the active scene graph from another thread, nor touch a property which might trigger an event which might modify the scene graph. Do use the concurrency utilities if you have network I/O otherwise you will freeze your app while the network I/O occurs and that is a "bad thing".
The Oracle JavaFX 8 documentation is good - read it and run a lot of the examples (except the ant based deployment ones and the Swing/SWT integration ones).
Ensemble is great, play with it and study the code to see for the samples (which you can view within Ensemble).
Binding is programming by side-effect, so be aware that when you change a property, it may trigger some potentially unrelated action through bindings or attached listeners.
Programming JavaFX in any language other than Java is an experimental thing, so only do that if you like experimenting and are prepared to do so without a lot of support.
Targeting embedded devices, iOS or Android for a JavaFX app is an experimental thing, so only do that if, yada, yada, yada.
JavaFX is a mid-level UI system, not a full application stack - it abstracts away the basics like rendering, controls and animation but does not provide comprehensive OS hooks, navigation frameworks, model/view/presenter frameworks, full dependency injection, client/server messaging, data <-> controls serialization and deserialization, etc. FXML is just a markup system with a binding capability to Java code. JavaFX and FXML do not constitute a full application framework. There is no widely-used full application framework for JavaFX. Sure some people have tried to create one, but none of those solutions have achieved critical mass of usage and features - plus a one-size fits all application framework will never exist anyway - client applications (e.g. a game versus a line-of-business app) differ greatly and deserve completely different architectures.
There are many things in the Java EE world which can be used in JavaFX (e.g., its dependency injection, its web socket or rest APIs and implementations, its server based systems to allow your app to access cloud based logic and storage, etc) - so feel free to use the bits you need, usually it's as simple as adding additional library dependencies to your maven or gradle project. A typical medium sized JavaFX application will include multiple third party libraries (mostly non-UI libraries) to get its job done as this will be more convenient than coding everything against the JRE API - though there is an awful lot of out the box functionality you get from the JRE.
JavaFX is more complicated to use than Delphi and in some respects doesn't supply as much functionality in terms of built-in stuff like data base backed tables (though it supplies a ton more functionality in style). It is not easier to create a complete business app using JavaFX than it would be to create a similar thing in Microsoft Access in the 90's. Such is progress.
JavaFX is portable across desktop environments (OS X, Windows, Mac). JavaFX apps have their own look and feel which is not like the native OS, but that is probably fine for a lot of apps. AquaFX does an amazing job of making a JavaFX app looks like OS X apps (kudos to the creators of both AquaFX and the JavaFX built-in styling capabilities).
Unlike some other portable frameworks like QT, you don't have to write C code, you can write Java code (which to me at least is a win). Similarly unlike HTML/CSS/JavaScript you don't have to write untyped JavaScript or make use of some obscure code snippet you pulled off the web for your button control. You don't have to use the web framework of the day which withered yesterday. Instead you have the (benefit?) of hardly any framework at all for JavaFX. You don't have to have your app live within a browser sandbox that another developer once described as the ghetto of application sandboxes.
So, as compared to HTML - I think JavaFX is kinder to the developer, though end users don't really seem to care that much and are fairly accepting of HTML applications even when their functionality is often inferior to many more traditional GUI apps. HTML is standardized, its full of standards, even the non-standard parts. Everybody used to implement all the standards differently or make their own standards, however now the standards are so painstakingly, nitpickingly prescriptive that everybody implements pretty much the same thing - except when they don't. JavaFX has no standard but its public API docs, it has just one implementation. If you code against the API, your app is probably going to work forever - at least if you bundle the runtime with your app, cause if you don't you might end up like the poor guy in the previous question who can't figure out how to update his app specific CSS rules to get his app to look the same with a newer Java version. JavaFX is a relatively niche technology and you don't have the legion of developers, tinkerers, industry investments and people just plain getting stuff done in any which way that you have with the whole HTML juggernaut. The major thing that HTML provides that JavaFX does not is: Sharable, browsable deep links to stuff with search indexed content. With HTML, Google will index it and you can link to and refer to other docs and other docs can link to yours. It is the HT in HTML which makes the web so amazing and the F in FXML doesn't match it. What is the F anyway?
That's a huge wall'o'text. Just some random thoughts and opinions. All opinions are my own. Your opinions may vary. That's OK. I don't think a discussion is needed. If you would like any clarification or further advice you can ask in new questions.

Cannot connect a Java GUI client to an EJB

I am having problems trying to make a Java GUI client connect to an EJB. I am using JRun4.
At first, I tried making the Java GUI client a part of the enterprise application that I am building (of which the EJB is a part of). I included the client as a Java module in the application.xml of the enterprise application.
However, when I try to start the server, containing this application, I get an error saying:
Application authentication required. Incorrect method call.
Now when I try to execute the application from the console, it works fine except when it comes to the part when it has to connect to the EJB. At this point I get an java.lang.reflect.UndeclaredThrowableException. Here's the stack trace:

Since the bean is local, I am using a local reference to the bean in the lookup in the code of the client:
Object o = context.lookup("local/BeanTest")
I tried to use:
Object o = context.lookup("java:comp/env/ejb/BeanTest")
and added an ejb-local-ref in the application-client.xml file of the client. But when I try executing the client in this case, I get an error saying:
No such binding: ejb
I wish someone can help me out with this. My main aim is to get the app client talk to the EJB. Thanks a lot in advance.

"scripts" are entirely different from GUI applications. What do you expect to happen when you run a Swing application through telnet on another machine? Do you expect the Swing UI to be magically transported to the local Windows machine?
Not gonna happen. Yes, like ejp hinted, you could run an X-environment on your local machine and have the Swing UI tunnel its output there, but are you sure you want GUI apps to run on a remote machine like that? It's not gonna be fun to work with, I'll tell you that.
Why not create a Java WebStart app (or perhaps even an applet) out of your application, so your users can run the application locally?

IPhoto 6.0 slide shows looks very distorted

I have a new 19'' widescreen TFT monitor on my mini mac and now my iPhoto 6.0 slide shows looks very distorted.
This widescreen TFT have a 16:9 aspect ratio (1440x900 pixel).
I found no setting in iPhoto for the screen with an 16:9 aspect ratio. There are only format settings for 16:10, iDVD or act monitor. But no one works fine!
Is there any possibility that I can show my "slide shows" in the correct format? (Also with black bars)
Can anyone help me fix this problem?
Thanks in advance

I am experiencing a very similar problem. Michael, have you solved your issue yet?
With my setup (PowerMac Dual G4 533 MHz with an NVIDIA GeForce2 MX graphics card, and Gateway FPD2185W monitor, native display resolution 1680 x 1050), iPhoto slideshows show pictures off center (taking up the right 2/3 of the display and leaving the left blank). The entire picture is also not visible. I'm sure it is switching resolutions when doing the slideshow since when I stop the show, some of my apps are in different positions on the display. I have tried switching stuff in the preferences, as well as trashing my old iPhoto prefs file. Nothing worked.
Thanks in advance for any insights!

Integrating Another Program Into A Java GUI

HI
I have 3 classes here. One is a Java GUI, the other two are involed in
stripping and processing of information off a webpage.
Of these latter two classes, one contains a main method which connects
to a webpage and reads the info off it, it calls the other class which
parses this information and holds the variables I need to create
buttons for the main gui!
Is it possible at all to integrate, the class that reads the webpage,
into, the Java GUI class.I need to do this to access the variables
that the parsing class is holding, as previously I have had to create
an instance of this class in the webpage reader class, but this was no
good to me as the GUI could not access this information, i.e can I
create an instance of this stripper at the begining of main in the GUI
class so as I can use the results for this for producing my buttons?
I've tried to do this but I am getting unresolved symbol errors. I was
wondering should I use global variables to hold the needed info also ?
Any help at all greatly appreciated,
Thanks
Gerry

I did what you're describing. Sounded simple enough. You put the same logic in main() into the applets init() and you can run as app or applet. Worked well in my IDE. Then the troubles start.
Visit
http://www.martinrinehart.com
and read the Article, Launching Applets. That will get you started on launching a Swing application. (Try my Sample, DawnPainter, to give you an idea about how nice this can be when it works.) I promise but don't deliver (yet) an article on the javascript library I wrote that solves all the problems. For non-commercial use you can get your own copy:

How can I run C programs under a Java GUI?

Hi
I'm looking for some info on how to run a command line program written in another language behind a Java GUI, any advice greatly appreciated, particularly in how to transfer data between the two.
Thanks

Runtime.getRuntime().exec(...)
Transfering info is more complicated. Maybe write and read status from disk?

Java System App Server 9 + CRLs?

Hi all -
I'm trying to set up my web apps under Java System App Server 9 on a Windows 2003 (Server) box. Everything is working just dandy, except that I cannot seem to get JSAS9 to recognize a Certificate Revocation List for my Certificate Authority certs. I have a URL specified in the CA cert's extensions for the CRL. I also have the CRL in all of my keys generated by the CA cert. Using Windows' cert manager, I can see that my keys and CA cert both list the URL correctly. I made two test keys, A and B, and added key B to the CRL. If I visit the URL specified for the CRL, I see that the key is indeed on the list. But when I visit my JSAS9 server, it still allows me to authenticate with it using the revoked key.
I also exported the CA cert key from my JSAS9 keystore and it only has the issuer name/owner name/valid dates/signatures, no CRL URL (the key I imported into JSAS9 most definitely does have the URL in the x509 extensions).
I haven't seen any config options for either specifying a static list of CRLs or for honoring the CRLs provided with CA certs or user certs. Anybody have any idea where to look for these options?
Thanks a ton,
Reid

ASP/COM to be converted into a Java/WebLogic app

Does anyone know if there is any methodology to convert an ASP/COM (microsoft)
app into a Java J2EE app like Weblogic ?
Please advise
Thanks a million
KK

Hi.
I'm unaware of any specific methodology. In order to save yourself some coding
you might take a look at a java-com bridge such as the JCOM bridge we have in beta
or some similar 3rd party product. This will allow you to keep and use some of
your existing COM objects. You might also search the web to see if there are any
tools that help you to convert from ASP to JSP.
Regards,
Michael
