I don't want application show message "Java web start in the bottom of app"

Dear
please help me.
I am using jdk 1.4.1_01 and JWS 1.2. when I launch application through web stat. In bottom of application , the title "Java web start" appears, it also appear in the bottom of popup menu, menu item bar, dialog,...
Can I disappear it.
Please help me.
Thanks

I don't think it's documented anywhere, but if you sign the jar, that message will go away.

Problem with CORBA application deployed using Java Web Start 1_6_0.

Java Web Start fans and experts:
We have been using Java Web Start to deploy the client side of a CORBA-based application since the inception of Java Web Start ... including Java Web Start 1.0 right up through the present.
With Java Web Start 1_6_0, we see evidence that Web Start is "tinkering with" the IOR that CORBA uses to communicate. In all previous versions of Java Web Start, independent of the JRE which the application uses, the stringified IOR have been the same size regardless of whether the application is deployed locally or via Java Web Start. With Java Web Start 1_6_0, the stringified IOR is much longer than the "real" IOR (again, regardless of the JRE used by the application itself). To me this smells like a bug in Java Web Start 1_6_0. Has anyone else observed this behavior?
Here are some specifics .... I've run the same client application with various JREs both with and without Java Web Start as the deployment mechanism. The application was compiled and runs against servers that are running JDK 1_5_0_09.
Here is the summary of my results from a Linux box running various JREs, various versions of Java Web Start, and also running as a non-JWS deployed application. I've listed the length of the stringified IOR in each case.
JRE 1.5.0 non-JWS client: stringified IOR length = 344
JRE 1.6.0 non-JWS client: stringified IOR length = 344 ... this, I think, excludes the JRE as the cause of these problems.
Java WS 1.5.0, JRE 1.5.0 JWS client: stringified IOR length = 344
Java WS 1.5.0, JRE 1.6.0 JWS client: stringified IOR length = 344
Java WS 1.6.0, JRE 1.6.0 JWS client: stringified IOR length = 1568
Java WS 1.6.0, JRE 1.5.0 JWS cleint: stringified IOR length = 1568
In all cases, the stringified IOR length is determined by the service receiving the message and is always running JRE 1_5_9_09 and is
always the same 344 characters in length UNLESS it was deployed
using Java Web Start 1_6_0, in which case it in nearly 5 times as big!
To me, it sure looks as if there is a problem with Java Web Start 1_6_0 to be adding so much to the stringified IOR. Note: it's hard to tell how different the underlying IOR is in the JWS 1_6_0 case because, unlike most other ORBs, the Sun ORB doesn't have a tool to extract the IOR into a human readable structure. However, I can think of no good reason why the identical application deployed using Java Web Start 1_6_0 should have a stringified IOR length that is different than that of the same application deployed in non-JWS form or should differ from the behavior seen in all previous releases of Java Web Start.
Any clues or suggestions? Has anyone else observed this behavior?
Thanks,
John

Hi.
I got a different problem. My Corba application works in JRE 1.6, but doesn't works in JRE 1.5.X. I got an unexpected error and my console shows:
getSubjectX500Principal NoSuchMethodError: java.lang NoSuchMethodError
#### Java Web Start Error:

Can you help me?

Java Web Start and the Mac OS

I am new to the Mac OS and to Java Web Start. Using Java Web Start to launch a Java application on the Mac is discussed in several of the posts here. However, in the requirement section of the Overview for Java Web Start says
"Requirements
Desktop/Client requirements:
The client machine requires support for the Java Runtime Environment (JRE), version 1.3 or later. Java Web Start is available for Windows 98/NT/2000/ME/XP, the Solaris Operating Environment, and Linux."
As you can see, Mac OS is not mentioned. Yet Java Web Start exists on my Mac. Am I looking at the wrong documentation? The document is located at
http://java.sun.com/javase/6/docs/technotes/guides/javaws/developersguide/overview.html#jws
I don't know how to use Java Web Start . I don't even know where to look for help. If anyone would care to offer some help it would be greatly appreciated.

You are looking in the right place alright. The reason OSX is not mentioned in the document (or, by extend, any of the official sun documents) is that sun does not (may not?) provide an official java release on OSX. Java on OSX is implemented by Apple (and much to the dismay of both users and developers, they are not doing a very good job). Still, Apple's java usually fulfills the same specifications as the official sun java, so you can take any one of sun's documents on webstart or any other technology and it will usually work on the Mac. You just can't expect sun to assure that a technology will work on a platform they have no control over...

Can we change the label of Java Web start at the time of downloading applic

can we change the label of Java Web start at the time of downloading application?
At the time of downloading application(jar files) java web start shows "Downloading Application" lable on it window , so can we change it so some other..

The 'splash' screen might be of interest to you.
Here is the quick description from the FAQ.
<http://java.sun.com/j2se/1.5.0/docs/guide/javaws/developersguide/faq.html#206>
Section 3.5 of the JNLP Spec. has more details on using a splash screen for an application.
(But if you mean changing the very first screen seen when downloading an application the first time, the answer is 'no'.)
Late addendum..
By the way - now I review your question, I note you stress 'while jars are downloading'.
There is another strategy you might take. Mark most of the application jar's as 'lazy' download, get the main GUI on-screen quickly, then use the JNLP API's DownloadService to fetch the rest of the jars, after the application is running.
This has the advantage that, then we can have complete control of whatever is shown on the screen during the bulk of the downloads. We might show ..a 'splash screen', or a dialog with the application name on it, or a progress dialog, ..or any combination of the three.

Application upgrade with Java Web Start

Dear all,
I need your help for my question.
What I need is the following. I developed an application with javafx. I want to create an exe file with an installar for the application. After application is installed, in a nex momento I want to distruibuite upgrade of application (for bug fixing for example).
I read about Web Start & JNLP but I didn't understood at 100%.
Should I obtain what I need?
That is, user from application clicks on Update button and application is updated to last version?
Or is it useful only for jre update?
PLease help me to understand, I want to know if I can use this technogy for upgrade system of my application.
Thanks,
Regards

Why always expect applications HAVE to run everywhere when the targeted users only dwell on Windows...
So far, I have found JWS to be unreliable for everything and even worse for JavaFX. Tried different settings (background, timout, etc.) in the JNLP for the updates and none work as expected. Basically the app may update but sometimes does not and no one can figure why... Sometime the app installs but JWS only gets a partial download of the JavaFX runtimes and still launches the app which either result in an undecipherable JWS error or the application crashing because some of the JFX base classes are missing. Of course sometimes the install fails and we still get an undecipherable JWS error... Sometimes it fails but the app get installed... sometimes the shortcuts are not installed or they get deleted but no re-created after an update or they loose their icons... and the list goes on and on... arf what a nightmare...
On some computers, offline launch sometime still need a 2 minutes timeout to start on Windows and never start on Linux because... it tries to go online...
Generally speaking for JFX it used to work better in 1.6.0_14 or earlier but each Java 6 release since has make JWS become more and more flawed.
Furthermore, there still the matter of tons of JWS issues that are yet to be corrected, like JWS irremediably crashing it's own cache from time to time or not always updating all the app's JAR files (that error was difficult to isolate and identify) or loosing app reference when updating the JRE. Additionally, the Windows desktop integration still leaves to be desired (app icon looks very bad on recent Windows and for some reason it looks like JWS does not make use of Java2D at all...).
There are ways to create native exe launchers for Java apps like Launch4J and you could make a pure Java app (with a very simple Swing UI) that actually calls the JWS executable to install JNLPs for your JavaFX app. I have done that to distribute a demo of my app on a CD and it usually works most of the time. I say most of the time because I have found some situation while JWS enters a deadlock while trying to register a JNLP and... and then nothing happens.
Additionally JavaFX's licenses prevents from distributing the JavaFX runtimes, so if you want to stay legal you still need to point to the JavaFX JNLP on the JFX site. As an alternate measure I have my launcher detect if there is an internet connection active and then open the browser on the JFX site (I warn the user before doing so) so the runtimes gets pre-loaded before the app is installed. This feels very weak but that was the only real way I could make that work (asking JWS to load the remote JNLP like I do for the local ones usually did not work).
Hopefully at some point they will get rid of that JWS crap, create a good web installer that can aslo be easily used offline and make a API so we can use it from the code... well... I do still hope this may happen some times...

Problems to download with java web start

Hola to all.
I have the following problem. My application not discharge of the server when you exist a new version. The application runs off line but when exist a new version must download the last version, is the idea.
If I execute for first time the "launch.jnlp" file ( that is to say in the client equipment never execute the application ) java web start connects and download correctly the application and starts application, and creates the icon on the screen. But if the application already existed java web start executes the application that there is in the client and not download the new version of the server. I think, that problem its happen because the time waiting the response of the server is too long, and executes the local application. To resolve this, i execute the application on java control panel in online mode, and this work ok, because find a new version.
I leave you the launch.jnlp file.

Unable to run my application using java web start

i have created one application and use java web start to download the application. all the files are succesfully downloaded but when i try to run the application an expected error occur. this only happen in my machine but not in other machine i'm currently using
-jsdk1.4.2
-windows 2000 professional 5.00.2195 service pack 3
-pentium III 870 Mhz
-x86-based PC
-RAM 256 Mhz
Anyone knows why, plz help me with this puzzle

Please post the information from the Web Start "Exception" and "Wrapped Exception" tabs when the error occurs (I assume the error was in fact unexpected ;-)
A blind stab in the dark would be that you don't have write permission to the cache directory on the second machine. Also worth checking that the proxy settings on the second machine are the same as the first (if they are on the same network).

it's working fine now.

Deploying no java applications using Java Web Start

Hi,
I am new to java web start. Is it possible to distribute non java applications using java web start. I have an APP which can run on a desktop in standalone mode. The app has jusy HTML and Java script files. Is it possible to package this app and deploying using java web start? I am assuming If it is possible, I can make updates to the packaged app in the web servers and the updates will be downloaded next time the app is used provided configurations are correct?
thx

The app has jusy HTML and Java script files. Is it possible
to package this app and deploying using java web start? Not really. Resources for JWS need to be zipped,
while this HTML/JS app. will (I guess) not work from
inside the depths of a Jar (or Zip) archive.
Note that you can organise for those files to be
downloaded and expanded onto a known place
on the user's disk, by using an 'installer' element,
but..
...I am assuming If it is possible, I can make updates to the
packaged app in the web servers and the updates ..installers are only called once, and do not 'update'.

Java Web Start and JDK Logger

The JDK logger uses the logging.properties file in the JRE lib directory. However I would like to use my own logging.properties file as part of the application that uses Java Web Start. This config file will be part of the application jar file.
The usual way to specify the logging properties file is by using the -D parameter
-Djava.util.logging.config.file=logging.properties
How do I specify my own logging.properties file for Java Web Start? TIA.

I'm trying to track down a solution to that problem too. The reason is because of the strange way webstart is creating its own log. It attaches a class: com.sun.deploy.util.LoggerTraceListener which records console messages. The way it does this is by generating its own log messages at the FINE level. If you look in the javaws.log file which is inside of the webstart cache area, you can see the result of this. On a mac this is located at: ~/Libraries/Caches/java/log
So if the console handler is configured to printing out FINE level messages then an infinite recursion happens. If you change the console handler's level so it isn't printing FINE messages then it works. But I want to see my own FINE level messages, so that isn't a good solution for me.
I tried setting com.sun.deploy.level=INFO in the global logging.properties, so webstart's log messages would not show up in the console. However, it appears webstart resets this level on startup.
If you set that property using the resource loading you figured out above, it might work because that should happen after webstart does its own logging configuration.

How can I open help file (HTML or .chm) from Java Web Start (new to JAVA)

Hi All,
Im trying to open the help file of my application.
When trying to access the help file from the GUI (pressing F1 for launching the help file), I'm geting the an error, something like:
"Can't show help URL: jar:file:C:\Documents and Settings\%USER%\Application Data\Sun\Java\Deployment\javaws\cache\http\Dlocalhost\P7001\DMwebstart\RMjar-name!/com/resources/helpFiles/MyHelpFile.html"
It seems that the file which is packed in a jar, was downloaded to the Java Web Start cache directory:
C:\Documents and Settings\%USER%\Application Data\Sun\Java\Deployment\javaws\cache\http\Dlocalhost\P7001\DMwebstart
The code which is activated when launching the help file is:
try
            ResourceBundle resourceBundle = DoubleResourceBundle.getBundle("Resource", "ResourceImpl");
            RuntimeUtil.launchFile(new File(resourceBundle.getString("help.file")));
        } catch (IOException e)
            // TODO Auto-generated catch block
            e.printStackTrace();
        }where the property "help.file" is in some property file in the resource bundle named "Resource", and looks like this :
help.file="com/trax/docs/help/global/MyHelpFile.html"
The function "RuntimeUtil.launchFile" knows how to launch any file in its default application, and indeed it does launches the html, when giving it an absolute path to the file on my PC, as "C:\Helpfiles\MyHelpFile.html" as such:
RuntimeUtil.launchFile("C:\Helpfiles\MyHelpFile.html");My question is :
The application is going to be deployed on a Customer PC. How can I access the html file from the code, with a relative path and not its absolute path on the customer pc, which I can't know?
I found these restrictions regarding web start:
(copied from "http://rachel.sourceforge.net/"):
*Rule 1: Java Archives only. No loose files.* All your resources have to be packaged in Java Archives (jar) if you want to have
them delivered to the user's machine and kept up-to-date automatically by Java Web Start.
*Rule 2: No file paths.* You can't use absolute or relative file paths to locate your
jars holding your resources (e.g. <code>jar:file:///c:/java/jws/.cache/resources.jar</code>).
Absolute file paths won't work because you never know where Java Web Start
will put your jar on the user's machine. Relative file paths won't work because Java Web Start
mangles the names of your jars (e.g. <code>venus.jar</code> becomes <code>RMvenus.jar</code>)
and every JNLP client implementation has the right to mangle your names
in a different way and you, therefore, can't predict the name with
which your jar will be rechristend and end up on the user's machine in
the application cache.Seems complex or impossible, to perform a simple task like opening a file.
Please advise (I'm new to Java and Web Start).
BTW, I'm working with IntelliJ IDEA 5.0.
Thanks,
Zedik.

How import policy file with Java Web Start

hi everybody,
I wrote an application launched by Java Web Start.
This application encrypt data on the client side and POST them to the server.
To encrypt I use JCE packages including sunjce_provider.jar, jce1_2_1.jar and
local_policy.jar and US_export_policy.jar.
local_policy.jar and US_export_policy.jar are not packages, each of them contains
a policy file.
When I test encryption on local no problem, but when I test with Java Web Start
I've got this exception :
java.lang.ExceptionInInitializerError:
java.lang.SecurityException: Cannot set up certs for trusted CAs
It's because the application launched by Java Web Start doesn't find local_policy.jar
and US_export_policy.jar.

thank you for your answer

Hi Nicolas,
If you migrate to JDK1.4 and use the signed Bouncy JAR, you could resolve the problem,
if you don't want to use unlimited cryptography.
See my posting on your other question.

PS. There is a mistake in my other reply, the "local_policy.jar" and the other files must have
to go into JRE/LIB/SECURITY directory

Include JAR with Java Web Start?

Hi,
i am trying to deploy a little java web start application, that sends an email if you click on a button.
If i now deploy the application as a java web start app,
nothing happens, but if i run the little app as normal
JClient app it sends the email.
Is it possible, that java web start does not know, where
the classpath is? And why isn`t throw an exception?
Source:
private void jButton2_actionPerformed(ActionEvent e)
try
HtmlEmail email = new HtmlEmail();
email.setHostName("mail.anyserverintheworld.com");
email.addTo("[email protected]", "Name");
email.setFrom("[email protected]", "Name");
          email.setSubject("What do you think it this?");
//          //          set the alternative message
          email.setTextMsg("Your email client does not support HTML messages");
//          send the email
          email.send();
          }catch (Exception ex)
               JOptionPane.showMessageDialog(Form.this,"laba",ex.toString(),JOptionPane.INFORMATION_MESSAGE);
}

Christian,
if it can't find the classpath of something, then it wouldn't be able to find the classes comntained and throw a class not found exception. So there must be some sort of error message showing somewhere. If not, use System.out.println() to write your own debug statements.
Another hint, instead of handling the Exception, throw it so that the Webstart console shows the stack trace. Maybe the problem you hit is a security issue of not being granted the permission to use sockets or network connections to send the email.

Bea Weblogic 6.0 and Java Web Start

We want to use Java Web Start on the Bea Weblogic 6.0 Application Server.
Is there any way to add the Java Web Start Mime Type to the Bea Weblogic 6.0 Server?
