JNLP launch in ZDM 7

I have 3 JNLP files I need to make available through the app launcher window for students (restricted desktop). I can run the app if I go to the folder and double click the jnlp file, but when I try to launch it through the app launcher, it does not fly. Either "not a valid win32 app", or "Could not launch (app name) (id-123. The filename, directory name, or volume label syntax is incorrect" I have the app pointing directly to the JNLP file, do I need to be doing something differently? Thanks in advance!

That's how you do it. I have an intranet site that they wanted
shortcutted to the desktop but it had to run in Internet Explorer. I
just ran iexplore.exe with the site as a parameter.

Jnlp-launch consumes too much time to operate

Hello all!
I want to discuss the UX we have using jnlp launch in JavaFX.
You can find jira-discussion here:
http://javafx-jira.kenai.com/browse/RT-14930
As you can see, it was recognized as major bug.
What's wrong with jnlp-start?
1. When user launch jnlp-file, red confusing window "Java 7..." appears immediately.
While it can be slightly useful in promotion purposes, but many of today's users will be disturbed. There is no association "Java means cool" today. Users wanted to launch new sexy app, but all they see is strange poster with "Java........."
Imagine pop-up window with "Adobe Flash XX.XXX" for several seconds every time when you try to launch flash game. Is it fine UX you await?
2. I don't know, is it independent issue, or tightly coupled with previous one, but jnlp-start really consumes large amount of time.
On my machine with SSD most JavaFX apps can be launched from jar in less than 1 second.
But launching same app via jnlp take about 4-5 seconds total.
I suppose, it is self-evidently that launch of app with .jar files on disk must consume not much time than direct jar-launch.

Hello,
1) Should there even be a jnlp-start pop-up? Maybe a setting with no web-start pop-up or maybe the developer can provide own image to pop-up?
2) It does seem a little slow. I see that in the jnlp file there are references to external URL's.... could it be that these URL's are being accessed every time the JNLP is launched causing this delay? Is the performance of the jnlp startup tied to the performance of the external site and its network?
thanks
jose

Using SSL with client auth from a JNLP-launched app

We have an application that is launched by JNLP, and which needs to make a mutually authenticated SSL connection to a server. The client cert and trusted certs that it needs to do this are stored in the Sun\Java\Deployment\security directory where JNLP knows to look for them. And Java WebStart itself seems to be able to use these certs just fine. However, our app seems blithely unaware of the location of the keystore/truststore unless we explicitly set the system properties javax.net.ssl.keystore and truststore. But we don't want to do that (it could be different for different users), and we shouldn't have to do that. So the question is, how can we use the same KeyManager/TrustManager that Java WebStart itself is using? Are they somehow available for the JNLP-launched app to use?
Failing that, is there a way for a JNLP-launched app to query the deployment properties? There are a bunch of properties to direct the behavior of Java WebStart (see [http://java.sun.com/j2se/1.5.0/docs/guide/deployment/deployment-guide/properties.html]), such as deployment.user.security.trusted.cacerts. These don't seem to be System properties. Can the app see them, or are the "private" to Java WebStart itself?

Using a DLL or .so in a JNLP-launched applet

I have a 3rd-party JAR which includes code that requires a DLL (or .so on Linux) to work and I need to use it in a JNLP-launched applet. What's required with Java 6 Update 16?
1. I believe I need to get the DLL inside its own JAR and mark it as a native library in the JNLP. Is that just a matter of using the jar command to put it in the JAR?
2. Must the applet then be signed?
3. If yes to (2), will the end user still get some kind of security warning before running the applet?
4. If yes to (3), will the warning only appear the first time the applet is run and not again after the JAR is cached?
5. Do I need to manually "load" the DLL inside the applet's code? If not, how else does it know where to find the DLL (like -Djava.library.path in an application)?
Thanks,
The Gibbon

I have a 3rd-party JAR which includes code that requires a DLL (or .so on Linux) to work and I need to use it in a JNLP-launched applet. What's required with Java 6 Update 16?Nothing different than other JRE's, what's the question?That was an introduction to my set of 5 specific questions.
1. I believe I need to get the DLL inside its own JAR and mark it as a native library in the JNLP. Is that just a matter of using the jar command to put it in the JAR?Yes it is.Good.
2. Must the applet then be signed?No, AFAIKWell see hear's the problem. The Google research I did before I asked the questions was confusing as some people said it needed to be signed and others didn't. My own tests have encountered security exceptions and I was trying to know if they were because the applet wasn't signed. The whole purpose of me starting this thread was to save me a lot of time messing around with these kind of problems not knowing if it's even supposed to work or not.
See? It's all so amazing easy that making a simple test would have taken less time than this whole thread.
This is why we talked about spoonfeeding.I don't see that it's amazingly easy when you disagree with the majority of the posts and information I read which were in themselves contradictory. It's obviously not a clear cut subject and everyone has a different opinion. I was hoping someone who had tried what I am wanting to do could just tell me definitively if it was ever going to work.
What's even more amazing is that you didn't add any duke!I have to say I don't know anything about adding dukes, that's why I didn't do it.
Real thrill is you're probably gonna meet some real problem depending on your actual needs! LOL!
BTW: most of us has good knowledge of JWS but isn't such an applet expert (which, maybe, you are), so, in your case expecially, coming here with a realWorldJavaWebStartFailure would have been for sure the best approach, that's all you should really understand, IMVOHO.I realise that JWS is not often used to launch true applets but still I hope someone here would have done it and been able to share their experience.

Any Recommanded JNLP launcher for webstart app?

Dear All:
I have some special requirement(such as load class dynamically by add URL to classloader of JNLP launcher,or to launch additional JNLP app from parent JNLP app.),but I can not wait until next versions webstart console .Cause IIOP/rmi object communication require some JVM version at both sever side and client side,force my webstart application have to stay in jre 1.4.x
Can any one recommend me any open-source webstart launcher ?
compatibility to sun's webstart console is also concerned.

Looks nice.
One note:
You should prevent to let drive letters to sneak into URLs:

#### Java Web Start Error:
#### JAR resources in JNLP file are not signed by same certificate
Although I have signed all the JAR files with the same JDK version.
It is working fine when I am launching the application with localhost but as soon as I am changing the localhost with the port number of server it is throwing exception.
Please suggest how to remove this error.

Well, before you get any (further) misconceptions, I will point out that nobody here cares who wrote the application..
.. using java web start.
I succeeded deploying 'Sun dynamic tree example', but when I try to launch my app, the browser print.. 'Print' or 'display'? The first I've never heard of, the second is relatively easy to fix.
But when I click on the jnlp file (from the windows explorer), the application start !!!
How can I debug my problem ???Get some CRC into your keyboard. It might end up electrocuting you, but at least it will unstick that '?' key.

Simple Example Needed of JNLP launch

Can someone please provide a simple HTML web page for launching the applet and also the associated JNLP file example that show HOW the applet is launched such that it starts/appears OUTSIDE the web browser. TIA.

>
Good, hard information instead of simply referring someone to "Google" would be a welcome change in these forums.If you had followed the link that Google represented ( http://www.google.co.uk/search?hl=en&q=jnlp+example&btnG=Google+Search&meta=&aq=f&oq= ) you would have seen that the 3rd result was a 'simple example' .
So, should I just copy the content of the 3rd result? Should I plagiarize? Should I spend time creating a 'simple example'? In my view I should do none of these - I should simply point out that Google will find many 'simple example' .

Jnlp launch failed

Hi,
I am trying to launch one application through browser by calling application's jnlp file
my command to a browser is
http://localhost/Application/DSApp.jnlp
I have installed application on my system and i have started my server.(tomcat)
I have javawebstart installed on my system.
when i am trying to launch the application through browser its showing the content of the jnlp file in the browser.
Kindly provide me solution.
with regards
Prabhat kumar

You need to add jnlp to the mime.types of the web server you are using.
For example in apache edit apache/conf/mime.types file and add the following line:
application/x-java-jnlp-file jnlp
This tells the web server to tell the browser to use the web start plugin when encountering this type of file.

JNLP launched via IPv6 address

We are running Tomcat (5..5.20) webserver on a machine configured with IPv6.
When laucnhing our application like:
http://[<IPv6 Address>]:<port>/<jnlp file>.jnlp
The application correctly downloads and starts, HOWEVER every client to server servlet request generates a new session id as noticed by:
public void doGet( HttpServletRequest request,
HttpServletResponse response )
throws ServletException, IOException
System.out.println("id = " + request.getSession().getId() );
When using its hostname or IPv4 address the same ID is printed.
Any ideas?

sounds like it is not getting the proxyie information correctly.
open the java console network settings tab and check what proxies are being used.

Response code 403 from server when launching jnlp

Ive searched the forums for this same problem to no avail. We have a reverse proxy server which requires authentication to log in. Once the user logs in, then they can run our webstart app. But when I run it, I get this error in webstart: Please pay attention to the "Caused by:" section of the WRAPPED EXCEPTION tab.

Java Web Start 1.4.2_05 Console, started Fri Sep 17 07:54:41 CDT 2004
Java 2 Runtime Environment: Version 1.4.2_05 by Sun Microsystems Inc.
If you look at the wrapped exception, the server appears to be try ing to bounch Web Start back to the login screen. Thats what that https://rptest.ca.boeing.com:443/ReverseProxy/Authentication.html is. Its the login screen. But I have already logged in! It is as if I tried to launch this app without ever logging in. Is there any way to run a web start app after you have authenticated into a server? Please help if you can, I'm really in a bind.
Thanks,
Steve

You may have logged in using your browser, but Java doesn't know that so it will need to login again.
However, there are some issues with regards to NTLM protected resources (e.g. those behind a Microsoft Proxy Server), which has apparently been fixed in 1.4.2 (meaning it didn't work with earlier versions). Perhaps this is what's happening?

Launch JNLP file which required full-qualified domain name

Hi all,
My suitation is like this:
I need to launch an JNLP file which I need a domain name in order to access it: (using JDK 1.5.0_11)
e.g. http://hostname.domain.domain/xxx/yyy/zzz.jnlp
But when it try to access one of the jar file, it will refer to http://hostname/aaa.jar that lead to UnknownHostException.
Note: (I already use the full domain name to launch the JNLP file..)
Any one have idea on what to do? And I have no option to change the network setting to support solely "hostname" without domain.
Here's the "little modified" Launch file in the error dialog (as some details can't be disclosed)
[Launch path]:
http://hostname.domain.com:12718/CMTE-3rdParty/tibco/7.5.2/tibco.jnlp
[Error message]:

Thank you very much.

You should change the codebase (declared in the jnlp tag) to http://hostname.domain.com:12718/CMTE-3rdParty
That's how jnlp works, URL are made up as codebase+href.
You'd better use absolute URL for the jnlp href (not for resources).
And, last but not least, as Andrew would say: use JaNeLa (look for a link almost anywhere in the forum).
Bye.

Launch File Error: Missing jnlp

Here is my XML. I don't see what I'm doing wrong. This is my first jnlp file so I know I probably done something wrong.
<?xml version=�1.0� encoding=�UTF-8�?>

<jnlp

What is the error message ?
