My web start app doesn't get cached

Many apologies if this topic has been covered before but I have extensively searched the archive and can't seem to find it.
I have made my own trivial web start app and it downloads and works fine with my installed web start software. The problem I have is that when I launch the web start application manager and start my app from there the app does not apear in the "downloaded applications" section and hence I can't get to run it unless I have a connection.
Firstly I though I may be missing the <offline-allowed/> element from the JNLP file but it wasn't that. Then I thought it may be because my jars aren't signed but then the examples from sun worked OK and they weren't signed at all.
I have checked in the web starts cache directory and it looks to me as if the correct jars are in there but still the application manager won't show my app as one of the downloaded ones.
Any help would be much appreciated.

The Java Web Start application Manager will only display applications who's jnlp files are cached.
In order to cache your jnlp file you need to include an href attribute for the jnlp element in your jnlp
file. This may not allways be possible if your jnlp file is programatically generated by a servlet,
but it works for static jnlp files.

Java Web Start.app, apparent problems.

I have been experiencing many small problems during web browsing, etc. and have received terrific help from Barry Hemphill but he is unable to help on Java matters.
When I open Java Web Start app. I get the following message; "You cannot open Java Web Start.app because it it is damaged or incomplete". This is possibly, at least by the app's. name the cause of my troubles, though I am guessing. Can anyone guide me to where I can download and re-install the app. to see if it does overcome my problems. A typical one of them is happening as I type, the screen characters are lagging heavily behind my two-finger typing.

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.

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.

Your jnlp checker Vanessa is quite useful.
Is the source available, because I would like to fix a bug or two I noticed.
Then check out Gentleware's Poseidon.
http://www.gentleware.com/download/Poseidon4umlJWS.jnlp
It is a commercial version of Tigris.org's ArgoUML, a free UML editor,
which is webstartable as well:
http://argouml.tigris.org/files/documents/4/0/0100/ArgoUMLWebStart.jnlp
Interesting about Poseidon was how they implemented key registration for their JWS app, a common task for commercial applications.
However Poseidon unwillingly illustrates limitations of the present JWS implementation - this beast is large (about 10-30 MB).
I loaded it at home via an ISDN link (8KB/s) and it took much time. The download was interrupted for several times, I hadn't start to download again from zero, because the app is splitted into several smaller jars, but still had to reload interrupted jars.
Some days later it turned out that the disk I had the JWS cache on got full. Thus I wanted to move my precious downloads to another partition, which is not possible. You can't move cache contents elsewere, so I had to redownload it again later (ouch).
An interesting bit about ArgoUML is how they speed up their large app by forcing class loading in a background thread. I saw that in their source and want to try out that technique myself soon, perhaps it gives a little speed advantage.

“Hi Kirby, thanks a lot for your answer.
I got one answer, from DMoore, saying:
“Try Safe boot and then restart with only Aperture open. Still doent work write back with more details like Ram, HD capacity/free space. Are these thumbnails or Previews? Have you turned off building previews in AP preferances?
Safe boot http://support.apple.com/kb/HT1564
Starting up into Safe Mode does several things:
1 It forces a directory check of the startup volume.
2 It loads only required kernel extensions (some of the items in /System/Library/Extensions).
3 In Mac OS X v10.3.9 or earlier, Safe Mode runs only Apple-installed startup items (such items may be installed either in /Library/StartupItems or in /System/Library/StartupItems; these are different than user-selected account login items).
4 It disables all fonts other than those in /System/Library/Fonts (Mac OS X v10.4 or later).
5 It moves to the Trash all font caches normally stored in /Library/Caches/com.apple.ATS/(uid)/ , where (uid) is a user ID number such as 501 (Mac OS X v10.4 or later).
6 It disables all startup items and login items (Mac OS X v10.4 or later).
7 Mac OS X v10.5.6 or later: A Safe Boot deletes the dynamic loader shared cache at (/var/db/dyld/). A cache with issues may cause a blue screen on startup, particularly after a Software Update. Restarting normally recreates this cache.”
As I don’t know much about the technical aspects of computers, I don’t really understand the first answer, and it sounds like following it might produce unwanted changes.
But I understand your questions, so I’ll try to answer them;
"loading from any Project" means that I encounter the problem when I’m using a project, possibly after/because I’ve left the Mac on overnight, and/or I’ve made a lot of adjustments, and, once the problem is there, it happens in any other project which I open – the images load then disappear.
I can see images in the Browser, so it only happens in the Viewer(s).
I’m afraid I don’t understand what you mean by: “If you select "Photos" from near the top of the Library tab of the Inspector, does it show you all of your Images?”. I am a newcomer to Aperture, so I don’t know what some of the buttons are for yet, but when I want to look at and adjust my pictures, I import them, as referenced images, then Aperture creates a folder/project in the Library. When I click on that Project (when it’s working properly), all the images appear in the Browser or the Viewers – without me needing to “select Photos from near the top of the Library tab of the Inspector”. I selected it and looked at all the items in the dropdown menu, but none of them seems to offer the option to ‘show all the images’. So I’m not sure how to answer your question except to say that – yes, I can see all the pictures in the Browser or the Viewers (when it’s working properly), but I don’t seem to need to use the Photos button to achieve this.
Did Aperture work before?
Yes it worked ok for a while, but I only purchased it on 24th May.
If I understand correctly, the difference between thumbnail and preview is that the thumbnail is what I see when the “Loading” wheel is turning, and the disappearance of this wheel after a few seconds means that I am now looking at the preview (also, the thumbnail cannot be adjusted).
So I think the problem occurs when the thumbnail has finished loading; the viewer going blank/grey might mean that it is not showing the preview.
But I have not changed the default Preview settings in Aperture Preferences.
My macbookpro details:
2.7 Ghz Intel Core i7
Memory: 8 Gb 1333 MHz DDR3
Hard Drive capacity 499.25 GB
Available 387.36 GB
I have noticed another problem: I cannot apply the same rating to multiple images: following the instructions, I select a group of contiguous (or non- contiguous) images, choose a selection eg “5stars” using the keyboard, but the stars only appear in the last selected image – even though all the images are still showing as selected.”
I hope this helps you to understand more.
Thank you for trying to help me.

Java Signing issues when loading web start app

Hey, not sure if this is the correct place for this - but couldn't think where else to put it...
I'm a bit stuck at the moment and i wondered if anyone could shed some light on my problem, and where I might go from here.
We've developed a EJB3 application that has a web start UI for users to start... The application is developed in Eclipse and compiled and deployed with ant build scripts... When we deploy the application from within Eclipse everything runs smoothly and users are able to start the web start app without any problems... However I've recently tried setting up a Continuous Integration server (Hudson) for us to test new deploys on and for this our build scripts need to be run outside of Eclipse...
This appears to run without a problem, however each time the system is deployed from here the web start application fails to start because web start cannot verify the signing in the client jar
Could not verify signing in resource: http://10.39.216.5:8080/mist2/lib/mist2-client.jarAs far as I can tell from the output of the build everything goes according to plan and there is little difference between the output if the build had been started in eclipse... The only big difference is that when building in Eclipse the build only packs up the compiled code, because Eclipse auto build the application, whereas in Hudson the code is clean built using the ant scripts (which are created by Eclipse)... and if I turn autobuild off eclipse and build the project from scratch using only the build scripts then the same problem arises...
I'm not really an expert on jar signing so I can't really guess at what might cause the verification to fail... any hints would be much appreciated. It feels like there is something that the Eclipse compiler does that is missing from the scripts but I can't think what this might be as the scripts are created in Eclipse
Thanks
Alex

Alex,
I believe your problem might be similar to one I had. According to one forum response (of course I can't find it now), if you have third-party JARs in your application (which in your case would be any eclipse jars), they might already be signed by their originators (as are eclipse jars), which may cause some really strange errors.
The solution for me was to package my third-party (that is, eclipse) jars into their own feature, separate from my application's feature. So, my main jnlp file has an extension to my application's feature jnlp, and that feature's jnlp file has an extension to yet another jnlp file containing the list of third-party (eclipse) jars. Of course, your jar list will probably be different than mine.
Here's all three files. Hope this helps!!

Java Programming - Run Web Start App Through IDE Using Existing JNLP(s)

I apologize for the cross post. I believe I mis-posted the first time. The thread belongs here.

You might try pointing JaNeLA *(<- link)* at it, and fixing any errors it reports. Ignore any optimisations suggested. The optimisations are not properly debugged and would not cause the kind of errors you report.
Oh, and a ++++ to that advice to to ensure the console pops open when encountering a web start app. Make sure the code is not [swallowing exceptions|http://pscode.org/javafaq.html#stacktrace] *(<- link)* at any stage.

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"?>

Screen Saver crashing my Java Web Start app

I've written a Java Web Start time tracker application that all employees run from the time they start work until they leave at the end of the day. The only problem is that there are a couple of people who from time to time find that the application has crashed when they unlock their Windows screen saver. The application window continues to show the screen saver image and the title bar says "Not Responding". In an attempt to get some clues, I had one person keep the java console running - but nothing new appears in the console.
I've personally tried crashing the app by using screen savers, but I cannot duplicate the problem. I've also tried letting my computer go into standby mode and I've let it hibernate. But every time, the application continues running as soon as I log back in.
Any ideas as to why the screen saver could trigger a problem like this for some users?

>

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) {

Then... http://java.sun.com/docs/books/tutorial/information/javawebstart.html tells me...
"This situation usually happens when your browser and your copy of Java Web Start have different proxy settings."
I click Start | Programs | Java Web Start | Java Web Start,,, then click File | Preferences | General
My choices are... Proxies: None User Browser _ Manual (User Browser grayed out)
If _ Manual checked then I get...
HTTP Proxy ______
HTTP Port _______
I'm running XP Pro via Wi Fi to a Linksys Wi Fi router to a cable modem... I'm also running Zone Alarm (tried turning it off but no luck)
I don't know how to set up the Proxy stuff... can any one please help me get this set up.
thanks - Will

OK, on my XP Pro system I went to...
Start IE -> Control Panel -> Internet Options -> Connections -> Lan Settings -> Proxy Settings
This is my 'Local Area network (LAN) Settings panel...
- user Proxy server for LAN is checked
- Address is blank
- Port is blank
So do I plug something in here... the ip address of my linksys wi-fi router and a port number or what?
My Java Web Start Preferences won't let me click 'Use Browser' only None or Manual
If I click Manual, I don't know what to plug into the HTTP Proxy and HTTP Port fields...
I tried the ip address of my router... thinking it may have a built in Proxy Server... and port 8080 as indicated by the Help page for the Java Web Start... but no luck.
I really appriceate any help on this...
thanks - Will

First Java Web Start download doesn't update, second time does

I'm using Java Web Start with our application. This release we upgraded to java 1.5 from 1.4. Now I have a few PCs, not all, that do not get updates the first time they launch the application. But when the launch it the second time they get the download. The jnlp didn't change between releases? Any suggestions? I'm not using lazy loads, in fact I'm using the default which should be eager.
Thanks.

Hi,
I have similar situation. At the machine is installed Java 1.6 u1. Setup first version of application. After deploy second version of application and run application start update, but console show that application use old packages. At the same time main package is uploaded? I'd try to use <update check="always"?> but there are no positive result.
At the same time then installed Java 1.6 u2, all works fine.
Any suggestion, how it could be resolved, without Java 1.6 u2 installation?
Thans, Kirll.

My web start app doesn't get cached
