Multi Apps in Web Start

The Web Start Demo (play.jnlp) shows four applications.
How to do it?
I need to do the same thing, i.e. show more than one app when I start javaws.exe.
Please help. I have searched and searched.....

As far as I know whatever you start from one JNLP file is treated as one application by Java WebStart. Perhaps the demo you are talking about just opens up 4 different (J)Frames with four different demo's. However, this has nothing to do with WebStart.

Problem running app via web start shortcut icon

Hi,
I need to install my application using java web start. I have created the jnlp file and when I run the jnlp file by double clicking on it, my app is starting well. Shortcut and desktop icons are being created. But when I double click on the desktop icon, then app does not run at all. In the log file , I notice that it is referring to some other location rather than the cache location and says "File not found".
Same way, when I use an html file to run the app, then my app does not run at all. That is, the html file displays a link, such that when I click on the link, the jnlp file is run. But app does not start. Log says it is referring to still another location and says "File not found". Can anyone help me out...
Thanks in advance.

Yes, this is with IE as the default browser. But, the FileNotFound Exception is not raised for the jnlp file. Instead FileNotFound Exception is raised for other files/folders used in my Application.
JNLP file is present in the web start cache. Sorry for not telling this clearly in my first post....
Actually what I need to do is to deploy Jetty server through web start. Jetty's "start.jar" has the main class and this class refers to the xml files and keystores in "etc" folder in the jetty home directory. As I need to transfer them through web start, I pack the "etc" folder into "etc.jar" and transfer it. When I run the JNLP file directly, jetty server is started. But, running the web start icon does not start the server.
I get the following exception in the console...
"java.io.FileNotFoundException:C:\Documents and Settings\..\Desktop\etc\jetty.xml(The system cannot find the path specified)
Is there a way to embed Jetty server in web start....?

How to call Web Start app from Web Start app?

Is there a way to call another Java Web Start Application from a running
Java Web Start Application, possibly from a different JNLP file?
Could this be done in a way that there won't be another virtual machine
launched; i. e. that the started Application will run in the same virtual
machine as the calling one?
Cheers,
Tobias

Im not sure about running in the same Jvm however there are two ways I know of to start another jnlp app. I am using this to essentially restart my application however, you dont have to do that and can start another web application by either using BasicService.showDocument with the jnlp file ( should start a webs tart app) or usign runtime exec with javaws and the jnlp as the argument.
    String jnlpUrlString = "commpartnersapp.jnlp?COMPANY="+COMPANY_ID;
    try {
      try {
        // Lookup the javax.jnlp.BasicService object
        //get the codebase
        //This will work on both Unix and Windows
        BasicService basicService = (BasicService) ServiceManager.lookup(
            "javax.jnlp.BasicService");
        URL codeBaseURL = basicService.getCodeBase();
        log.config("basicService.getCodeBase()=" + codeBaseURL.toString());
        basicService.showDocument(new URL(codeBaseURL, jnlpUrlString));
      catch (UnavailableServiceException ue) {
        //here for testing purposes since we are not started from jnlp in IDE
        log.log(Level.SEVERE,
                "ClientFrame:jMenuItemResetUserId_actionPerformed", ue);
        //when we are in the development environment
        String codeBaseString = "http://compub.cms/web/webportal/soft/";
        //Note this will work on windows only, javaws always in path
        //see http://java.sun.com/developer/community/chat/JavaLive/2005/jl0301.html
        //works on windows
        String execString = "javaws " + codeBaseString + jnlpUrlString;
        log.config("execString = " + execString);
        Process application = Runtime.getRuntime().exec(execString);
      catch (MalformedURLException ex) {
        log.log(Level.SEVERE,
                "ClientFrame:jMenuItemResetUserId_actionPerformed", ex);
    catch (IOException ex1) { //runtime exec throws IOException

1) Whenever you see a message from Java,

effect of 'cannot find..', try checking the URL of the

up '404' (not found), then the Java tool or app.

That is the first and fundamental problem with that

in a JNLP, and I would recommend removing it entirely
rather than try and hunt down any NetBeans DTD.
With the way NB writes JNLP's, I would not trust
a DTD written or controlled by them, in any case.

- removed DOCTYPE line with reference to '404' DTD

- removed redundant 'download="eager"' attributes as well
as main="false" and version="" from swing-layout.. jar element
- removed broken(?) <icon> element and empty <description>

XSL Transformation won't run in Web Start

Hello,
I am using the javax.xml.transform.Transformer implementation built into Java 1.5.x to transform an XML document into HTML using an XSLT transformation source. This code works perfectly if I run the app outside of Java Web Start. However, if I run the app in web start, the output is partial. More specifically, the XML and the XSLT load just fine in web start (I've confirmed this), but the end result of the Transformation is a properly formatted HTML document with only part of the data -- a bunch of data is missing.
I have some loops in the XSLT that print out rows in an HTML table with the data I want to see. These loops don't seem to run when I'm in web start, but the rest of the transformation does run.
I've confirmed this is not working on both Mac OS and Windows, version 1.5.0_06 and 1.5.0_09. So I don't think it is a bug on any particular platform. I am totally stumped by this. The XSL transformation process is doing something different in web start than it does when run from the command line (either different jars are in play, or system properties are different, etc).
Has anyone else experienced this?
Thank You,
Eric

One thing I'd like to mention...
My XML document has no namespace defined, and neither does my XSLT transform document. I am just referencing plain old string element names that simply match between the XML and XSLT. This all works fine when the Transform is run from a java app that is started on the command line. Things break down when the app is run via Java Web Start. Could the namespace issue be the problem, however? I don't see how that could be as the code works from a 'normal' java app, but maybe I'm missing something.

Mac OSX 10.6.2 Java 6 Web Start not always version checking on launch

When launching a Swing app via Web Start on Snow Leopard, it will often fail to discover and download the new version. This feature works consistently with Java 6 on Linux and Windows PC's.
The web-start app is accessed using an Application Bundle created with the Java Preferences app. If I clear the cache in Java Preferences, Web Start will nicely download the application and run it. However, after deploying a new version of the app, the Mac client will often run the cached version of the app without downloading the new version. Is anyone else experiencing this problem?

Re: "Alternatively, if you don't want to do this, the only other option I am aware of to solve this problem is to buy software like Fusion or Parallels and install Leopard (10.5) as your OS and run MX 2004 within a virtual environment."
Just so this is perfectly clear..... NO CAN DO
I have VMWare and Parallels on a Brand New MacBook Pro. It came with 10.5.11 and that is absolutely the OLDEST Mac OS I can install in a virtual environment. Believe me, I tried Tiger, Panther and Jaguar to no avail.
If the Mac in question came loaded with Snow Leopard, it has a "Snow Leopard or better" firmware write on the logic board and it will not allow an older OS to be installed.... even in a virtual environment, unless there's a secret that nobody I've spoken to in support for both VM clients knows.

Unofficial Web Start FAQ Update

Hi,
I've added new entries to the Unofficial Web Start FAQ Update/Errata page residing at the Lopica Web Start Paradise site online @ http://lopica.sourceforge.net/update.html
New entries include:
* Where can I find the Web Start source code?
* How can I start my Web Start app as a Windows Service?
* How can I debug apps under Web Start?
- Gerald

You can debug JWS apps using standard ouput. In that case you need to
display the Java console. OR you can use log files.Thanks for your comments. The FAQ Update entry adds new tips and tricks on how to attach a debugger to your app kicked off using Web Start. You might wonna check out the "original" entry in the FAQ first.

Web Start beginner - Web Start front end to existing web app?

Hi all,
I'm new to Web Start, though have been hearing about it for some time. Even after reading the documentation, I have some basic questions about it.
Specifically, is it possible to invoke business methods via something like a Struts ActionServlet through a Web Start gui? That is, say my Web Start app and my existing web-based Struts app were on the same server, could I easily invoke the ActionServlet by passing in a URL with parameters? Thus giving me the ability to completely reuse my 'MC' of my Model-View-Controller app, and just replacing/adding another view ('V')?
Has anyone ever done this? If so, are there good examples?
Thanks in advance,
Mike

WebStart is a deployment mechanism for otherwise perfectly normal Java applications. WebStarted applications run on the client, not the server. WebStarted apps run in a protected environment (the Java sandbox), meaning they can't do potentially harmful things on the client machine such as reading and writing files or creating network connections to any server other than the one they were loaded from, unless you obtain special permissions from the user (the application needs to be signed for this to happen).
So there is nothing that specifically prevents you from using a WebStarted application as a front-end for a Struts webapp. If it makes sense to use a client-side application for that purpose is a question only you can answer.

Passing a parameter to a Web start app

Hi, I'm having trouble getting a single integer value into my web start application. I understand how you do this with a JNLP however I need a different value for this integer depending on a PHP script. With applets it was fairly simple but with web start apps it seems a little more complex - the only way I could think of was to recreate the entire JNLP file via the PHP script which seems a bit cumbersome if all that's changing is a single integer.
I had a look around on the web for information about this but it seems that information on passing parameters to web start applications is few and far between.
I'd be very grateful for an answer!
Thanks.

alex.p wrote:
So in this case how would I pass the integer as a parameter to the webstart app. Is there no way of simply putting it in the link to the JNLP e.g ?
You could do that if you liked. Is there some expectation that the user will run the web start application after you do that? Or that the user won't already be running it? Or that the user will ever run it? I think you should back up and try to figure out what the point of this parameter is. Is it supposed to make something happen? Or are you just changing the application for the next time a user gets around to using it? Or what? As I said, this really doesn't make much sense so you need to provide a requirement that does make sense if you want to get anywhere at all.

Java console doesn't launch when starting Java Web Start app from Firefox

Updated my Linux desktop from RHEL to Fedora 12 with resultant upgrade of Firefox to 3.5.9 and now when I launch our Java Web Start application, no Java console appears. The Java Control Panel still shows "Show Console" as set. My app uses Java 1.5 which I have installed on my desktop.
What do I do to properly configure my browser/desktop to support use of the Java console?
Please help, I need to debug our app!

..Please help, I need to debug our app!Cannot tell you the answer to your FF hassles (because I have no idea why you're seeing that behaviour(1)), but note that you might be able side-step FF by launching a JWS app. using the javaws tool directly from the command line or an Ant build file.
1) Though you might try rebooting the machine if any installation/configuration changes have occurred since last boot.
Also note that many problems with JWS apps. can be sorted be checking the JNLP using JaNeLA.

Why does Web Start App ignore Proxy bypass/exception list in Proxy settings

Hi All,
I've been pulling my hair out on this one for a while now and finally decided to see if someone can help me out.
In my office I have a intranet of numerous devices and pcs connected. There is also a proxy server on the network to allow connection through the the internet. I have my proxy settings setup to bypass the proxy for any addresses on my intranet. This is set in the normal way by adding ( http://192.168.1. to proxy settings exception list in IE. This proxy bypass list works fine for all other situation except the following:
On my Intranet I have an embedded web server device I have been developing that has a java application deployed using web start. This application is a monitoring tool that allows the user to check the various settings and status of the embedded device. The problem is that when the app is launched for some reason web start tries to get the require jar file from the proxy instead of directly from the device, even when the IP address of the device it is trying to get it from is in the bypass list?? I don't think Web start is checking the exception/bypass list in the proxy settings to see if it should be using the proxy or not?? I can see this by using wireshark and inspecting the GET HTTP requests sent from my pc to the proxy server instead of directly to the ip address of the embedded device.
If I change my proxy settings to use a direct connection/no proxy (untick the "use proxy server for your lan" box in IE settings) then everything works fine. However this is not a workable option for my customers as they don't want to have to continually change these settings when connecting to this device and then to the internet (which is the whole reason of having the exception / bypass list).
I've tried many things including using the proxy settings in the Java console instead of getting them from the browser but the same thing occurs.
Any help would much appreciated, as I not sure if it is something I am doing wrong, or a possible bug, or just the way it is meant to work??
I'm using the following...
Java version: 1.6 1.6.0_17
Operating system: ( I've tried XP and Vista)

I have the same problem, please anyone can help?

Different signded jar in the same web start app

Hi there
I have a web start application that use an external security provider. The jar file of the security provider is signed (otherwise it don't run under jdk 1.4.1) and the jar with my application is also signed with other signature, because i need full rights on the client. It is not possible to start the application, because webstart not allows to start the app with jars signed from different certificates.
Anyone have an idea how this problem can be fixed?

I'm pretty sure this has been answered here before, so you may want to do a search to get a more complete answer. Basically, you need to sign the other JAR files with different certificates in a separate resource extension jnlp file, something like:
<extension name="Java Help" href="help.jnlp"/>
and then list the other jars in that file, something like:
<?xml encoding="UTF-8"?>
<jnlp spec="1.0+" href="help.jnlp">

Java Web Start opening code not app

For the past year I have had no problems opening up *.jnlp files with Java Web Start. Starting last week when clicking on any link to launch a Java app I get the code opening up in TextEdit.
For example when I click on 'Welcome to Web Start' on this page: http://developer.apple.com/java/javawebstart/ I see (just to start)
<?xml version="1.0" encoding="UTF-8"?>
<jnlp spec="1.0+" codebase="http://developer.apple.com/java/javawebstart/apps/welcome" href="JWS_Demo.jnlp">
<information>
<title>Welcome to Web Start!</title>
<vendor>Apple Computer, Inc.</vendor>
<homepage href="http://developer.apple.com/java/javawebstart" />
<offline-allowed />
Can anyone please point me to a way to repair my Web Start installation? I give a lot of webinars and they all require that Java work.

ISSUE
After the Java update, jnlp files are opened by TextEdit and not Java Web Start.
SOLUTION
1. Find the jnlp file on your machine
2. Get Info (Cmd+I)
3. Expand the “Open with” section
4. Select “Other”
5. Navigate to Macintosh HD/System/Library/CoreServices/Java Web Start
6. Check the “Always Open With” option
7. Click the “Add” button
8. Click the “Change All...” button

Web Start - Can't Connect To App Modules

Has anyone had the problem of on being able to connect to their application modules deployed to Ora AS 10g when using web start?

Hi,
Did you have a look at
http://www.oracle.com/technology/products/jdev/collateral/papers/10g/adfjclientbcwebstart.pdf
If you are deploying your BC modules as EJB then this document also contains information of how to test this deployment within the BC tester.
