Java Splash Screen

Hey Everyone,
I can't for the life of me get the Java SpashScreen to work. I have tried to run the example provided at [http://docs.oracle.com/javase/tutorial/uiswing/misc/splashscreen.html] however no matter how I try to run it i always get a java.lang.NoClassDefFoundError. Any ideas as to what I am doing wrong.
I would eventually like to package my splash screen into a jar file for my application but first I would like to get the demo to work.
Thanks,
Nath5

I think where you are going wrong is when you assume that error message has something to do with the fact that you're trying to use a splash screen. Since splash screens only display an image and don't require loading any classes, I would expect that messages about failing to load a class aren't related to your use of splash screens.

Java 1.5 Update 6 Splash Screen

I have a client who operates in a dark space and does not want bright white backgrounds or white splash screens. It is easy enough to use BGCOLOR="black" in the body tag of the applet containers. However, the Sun animated splash screen logo is my last challenge. I don't want to get rid of it so much as I want to color it a dark shade of grey or black. Anyone know if it is possible to darken the color of the background on the "Java Loading" splash screen ?

You may have video problems. Check for the most current video driver version (from the video card provider, not the computer supplier.)

Java6 splash screen in java webstart

I can't get the java 6 splash screen working when running as a webstart application .
I don't mean the splash you get while downloading but the one that's been introduced in java 6 that's showing while your app is starting.
So far I tried adding it in the manifest file of the main jar, adding the classpath switch in the jnlp file , adding the classpath switch in the JAVAWS_VM_ARGS but none worked.
Is there any documentation on this ? Or how should it work ?
Bart

Here's a very simple version:
public class SplashScreen extends JWindow {
    public SplashScreen () {
      JLabel image = new JLabel(new ImageIcon(SplashScreen.class.getResource("icons/splash.gif")));
      this.getContentPane().add(image, null);
      this.pack();
      Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
      Dimension imageSize = image.getPreferredSize();
      this.setLocation(screenSize.width/2 - (imageSize.width/2),     screenSize.height/2 - (imageSize.height/2));
      this.setVisible(true);
}This assumes a sub-folder in the same folder as your SplashScreen class named icons, containing a file splash.gif.
You will need to dispose() of the SplashScreen object when you have finished with it.

Sorry that's untrue. I have Photoshop CS3 running on 10.9.
CS9 or 10? Now you are just making stuff up.
Adobe claim CS3 will work, with a minor issue…

The Adobe updater fails to work for me.
I was prompted to install J6RE which came from Apple, check the Apple support downloads http://support.apple.com/downloads/#java%206
Sorry can't provide a direct link, it was just a dumb 'You need … please click install' dialog.
I think the 10.9 java updater is installing version 7.

Splash Screen generates   java.lang.NoClassDefFoundError: Eapply errors.

Hi Everyone,
Again, I am new to Java (2nd month actually coding) and don't know of a better place to post this problem. Also, the forum does not have a search feature (that I can see) so I apologize if this issue has been raised and discussed before (which it probably has been).
I am trying to utilize the new splash screen facility in SE 6 but have run into a problem. The image will display just fine but I get 'class not found' exceptions immediately afterwards. It seems as if the launcher cannot see the class containing main.
I guess I need to mention the fact that I am using the Galileo version of Eclipse. I checked the project settings and confirmed that the class, in this case, Eapply, is in fact in the class path so I am at a loss as to why it cannot be found. My code reads pretty much like every example I have seen of the splash screen functionality, so I can only imagine that the problem lies within environmental settings or something else I am not taking into account.
Here is the code I am using minus any lines not necessary to illustrate the problem:
Command line
-splash:images/vessels.jpg Eapply
Class
public class Eapply extends App implements ActionListener {
     public Eapply() throws SQLException {
          super("E-Apply Electronic Application", App.getCompanyID(), true);
     public static void main(String[] args) throws SQLException, ParseException {
          eapp = new Eapply();
The stack trace
Exception in thread "main" java.lang.NoClassDefFoundError: Eapply

Any suggestions you can offer will be greatly appreciated.
Thank You,

I fixed the problem. Seems as if the classpath, while being launched within Eclipse, was correct. However, the classpath was not set correctly if you tried to launch the app from outside of eclipse. To fix the problem, I specified the -classpath option on the command line.That's a very typical problem, and one reason why IDE's should not become addictive to the point that you can't do anything without it. Yes the IDE handles setting the classpath for you. But of course the actual users running the software will not be using an IDE to run it, so you must become very acquainted with what the classpath is and how to use it.

How can I customize the Java Report Panel applet splash screen?

Has anyone found a quick and easy way, either via javascript or a webi properties file, to cutomize the splash screen for the Java Reporting Panel applet while it is loading? I've found a few code snippets for the javascript approach, but they don't quite work, and apparently there's a webi properties file that I should be able to use to accomplish this, but where is it exactly? Is it on the BO server, or should it be in a jar file in my project. Can't seem to find it. Thanks for any help.

Look at the link I posted, you aren't double buffering correctly.
I saw the other post you mistakenly made before you edited it. Not really a big deal, I was just wondering why you did that.

After Effects CS5.5 - Lion: Crash on splash screen EXC_BAD_ACCESS (SIGABRT)

So one day, out of the blue, After Effects stops wanting to open. The worst part is, I can't think of any changes that would have caused this.
I am running After Effects CS5.5 (10.5.1) on my MacBook Pro 13" (Early 2011), which is running Mac OSX Lion. Here is my system profile (with some sections omitted).
Just a few weeks ago, I began to consistently receive this message during the AE splash screen:
After Effects Alert
Last log message was: <140735295236448> <ASL.ResourceUtils.GetLanguageIDFromRegistry> <0> Unable to obtain the User 'Language' registry key at: Software\Adobe\After Effects\10.5.1\ Defaulting to 'en_US'.
Here is a crash log.
Any ideas?
First attempt
I figured maybe I had a bad preference file, so I cleared my prefs. Nothing changed aside from a modified error message:
After Effects Alert
Last log message was: <140735295236448> <DynamicLink> <5> 0x114ee8418
And a crash log.
Also, if I try opening AE again, after I cleared my prefs and opened it once, the error message returns to the "registry key" alert.
Second, third, fourth attempt
So I uninstalled and reinstalled After Effects about 3 times. No change. I used the latest download from Adobe, and the original Master Collection image: no difference.
Fifth attempt
I created a second admin account to see if this was an isolated issue. It isn't; same problem.
Sixth attempt
I thought about QuickTime, so I opened up System Prefs, and uninstalled Perian. I left the prefpane there though.
Also, I have the latest version of Java.
Seventh attempt (Added 19 March 2012)
I used the Adobe Creative Suite Cleaner Tool to wipe out my entire Adobe installation. I still have the same problem after a reinstall. I'm going to try installing AE on my external drive next. This is really frustrating. Has anyone experienced this issue and found a resolution?
Notes
Interestingly enough, all of the other Abobe CS5.5 apps I installed work fine:
Bridge
Photoshop
Illustrator
InDesign
Premiere Pro
OnLocation
Extension Manager
Added 1:54PM, 13 March 2012:
Also, opening up the render engine causes the same error message.

I just installed AE, have never used it, and am seeing it bail on startup with the same odd language registry key error. Please see my post on a related thread.
Any luck here? Would be nice to get AE to boot so I could evaluate it.

SQL Developer locks after splash screen

I have succesfully installed SQL Developer on 2 machines in our group and it works fine. However on the machine where we really need it (mine) it absolutely refuses to work.
It appears to start up, the splash screen appears and the sqldeveloper.exe appears in the machine's task list but thats it! The splash screen stays on the screen until I click on it and then disappears.
I have tried the version with the built in SDK and I have also downloded the SDK from Sun and tried the version without the accompanying SDK. I have also de-installed all the Java SDK and runtime versions on the machine and re-installed those that were needed. Same result.
At this stage I called in our Java development guru who twiddled and tweaked during 30 minutes...same result.
If I execute sqldeveloper.exe from within the jdev\bin folder I see the following in a DOS box:

Is there a way to speed up the "Java Loading" screen time?

Hi.
I'm having a big problem with that. I'm running the JRE 1.6u3 on Windows XP SP 2, on an AMD Athlon 64 X2 Dual 3800+ (2GB of RAM), and the "Java Loading" screen time of web started apps is too high (about 15 seconds when I just restarted the pc, and 10 seconds after the first load... is that right?).
What Web Start do when it is "loading" ? The loading time of a standard client VM is pretty faster (like, uh, 1/4 second?).
Thanks.
Hidralisk

The Java Loading splash is only shown untill the Main class of java web start is invoked and can put up the download progress dialog. I don't know why it would be so sow, but this should be improved by the Java Quick Start featurew put in jdk 6u10 (see http://download.java.net/jdk6/)
the bug 6506138 has been escallated and is being vigorously investigated. (it would probably pertain more to the time durring which the download progress window is shown or beyond)

Splash screen with progress bar and multiple jar files to load

Hello,
I have been looking to the new features in java 6 for splash screens. I haven't implemented this never before and i was wondering how i could do the following with java 1.5 or 6:
I would like to see a splash screen with a progress bar that "grows" when every jar file has been read.
At this time i call my application like this from a shell script:
exec "$JAVA_BIN" -Djava.library.path=$LIBRARIES_J3D -classpath xxxx.jar yyyy.jar zzzz.jar ...
where xxx.jar, yyy.jar and zzz.jar are very heavy jars.
So i would like to see in the progress bar 33% 66% and 100% when they are loaded.
I do not know if this is the right forum to ask for this. If no, please point me which would be the ideal one.
Any help will be very useful. Thanks to all!

Splash screen ABAP (Was 6.20) SAPGui 6.20

I love splash screens. A small pop-up window with a picture should come for say 5 to 10 seconds and disappear by a timer task.
Giving such timer splash screens at START or END makes the application attractive. I do it in VB PB & Java.

Useful Code of the Day: Splash Screen & Busy Application

So you are making an Swing application. So what are two common things to do in it?
1) Display a splash screen.
2) Block user input when busy.
Enter AppFrame! It's a JFrame subclass which has a glass pane overlay option to block input (setBusy()). While "busy", it displays the system wait cursor.
It also supports display of a splash screen. There's a default splash screen if you don't provide a component to be the splash screen, and an initializer runner which takes a Runnable object. The Runnable object can then modify the splash screen component, for example to update a progress bar or text. See the main method for example usage.
It also has a method to center a component on another component (useful for dialogs) or center the component on the screen.
NOTE on setBusy: I do recall issues with the setBusy option to block input. I recall it having a problem on some Unix systems, but I can't remember the details offhand (sorry).

Custom splash screen for app under JWS 1.2 from 1.4.1 beta?

Has anyone gotten a custom app's splash screen to come up instead of the damn Sun Java Web Start splash screen to come up when the app starts from a desktop icon or if you launch it from JWS?
I added it to my jnlp file as specified in the docs, but it just doesn't come up :-(
<description kind="tooltip">TransMedia 2</description>
<icon kind="default" href="transmedia.gif" />
<icon kind="selected" href="transmedia.gif" />

<icon kind="splash" href="transmediasplash.gif" />

Hello,
I read your postings here and I did what you proposed.
Nevertheless the splash screen doesn't show up.
I'm using Java 1.4.1, Web Start 1.2; the jnlp file
looks like that:
<?xml version="1.0" encoding="UTF-8"?>
<jnlp codebase="http://venus/example-client/" href="example.jnlp">

</resources>
<application-desc main-class="com.mycompany.ui.Example"/>
</jnlp>
any idea why webstart doesn't use the custom "splashscreen.jpg"?
a properly splashXXXXX.jpg has been created in .javaws/cache/splashes, as well as an entry in splash.xml.
thanx for help,
michael

Custom splash screen only shows up when command line is used...

Hi,
Everything in my Java web start application works perfectly but, the custom splash screen only shows up when command line is used ("C:\Program Files (x86)\Java\jre7\bin>javaws -verbose http://www.xxx.eu/AcSentVivresCrus/AcSentJnlp/AcSent.jnlp"), if I use the shortcut on the desktop or in the start menu, the Java 7 splash screen shows up (tested under Windows Vista and Seven). Does someone have any clues?
Thanks...

Hi again,
I made some researches :
- The link in the generated shorcuts ("C:\Windows\SysWOW64\javaws.exe -localfile -J-Djnlp.application.href=http://www.xxx.eu/AcSentVivresCrus/AcSentJnlp/AcSent.jnlp "C:\Users\Arnaud\AppData\LocalLow\Sun\Java\Deployment\cache\6.0\46\69c1e9ee-1f252d1a") is not the same as the one I use in the command line ("C:\Program Files (x86)\Java\jre7\bin>javaws -verbose http://www.xxx.eu/AcSentVivresCrus/AcSentJnlp/AcSent.jnlp"). Is there a way in the the JNLP file to tell how to generate shortcuts (not the icon, etc., but command line options)?
- This sample (https://blogs.oracle.com/thejavatutorials/entry/changing_the_java_web_start) displays the splash screen when I click on the the generated shortcuts (I use Windows 7). I have copied the ButtonDemo jar file and the JNLP file on my IIS web server (Windows 2008 Server), this time the splash screen does not show up when I click the generated shortcuts but always shows up when I use the command line. Can someone tell me if it is a trouble with IIS ?
Thanks again...

Custom splash screen not appearing in the Dynamic created jnlp()

Hi,
I am not able to show my custom splash screen while starting the webstart application, instead getting the "sun webstart logo". I am dynamically generating the jnlp file using jsp (struts application). Application is working perfectly except custom splash screen. Below is my jsp which will generate the jnlp on fly. The test.gif file is in place.

</jnlp>If I use normal servlet - jsp using RequestDispatcher to forward request to a jsp which on fly creates jnlp, it shows the my custom splash screen. I am not very sure where is the difference. If I look at both generated jnlps they are almost one and the same. Can any one throw some insight on this.
Thanks & Regards,
Satyasai

Hi Andrew,
Thanks for your response.
1. I have launched it number of times but no luck.
2. I have written a jsp (using servlet + jsp no struts frame work) which will create jnlp on fly, which is showing my custom splash screen. If you refer in the initial post, it is not working with struts kind of framework. See the below jsp which shows custom splash screen. It worked without href.
3. All jnlps are well formed and perfectly working in my development environment. For security purposes I have not shown some of the texts and logos.
