Deploying a JNLP file to corporate users?

When it comes to Java, I'm pretty clueless. I was a VB programmer years ago, and now I deal mostly with Python apps.
I have a corporate client with ~80 workstations. One of their primary business applications is deployed by a jnlp file. Their tech support said to go to http://theirapplication.com/app.jnlp and the program will install.
I have tried a few test methods of getting this pushed out to every user.
The first was to deploy a shortcut to their desktop called "TheirApp" which pointed to that jnlp file.
In practice, that launches IE, downloads the JNLP file, checks if the app is installed, installs it if it isn't, and then runs the app. Plus, the app drops a new shortcut onto the desktop for directly launching the program. The shortcut points to javaws and then a long path to some per-user cache folder. So now users are confused by two shortcuts.
When the app initially starts, it asks for a bunch of settings--like really long account numbers. All this info appears to be per-user. So when users sit down at a different workstation (which happens frequently in their environment), clueless users are asked to install the app and put in all those initial settings.
The second method was a failure--I tried deploying a shortcut to start javaws pointing to that cache folder. I didn't really expect it to work. On new machines it failed because that app hadn't been installed into that cache folder yet. On existing installs, it would work for users that had previously installed it, but new users wouldn't work because the cache folder is stored under a different users settings folder.
So I guess my questions for the Java community would be these:
Is there a way to deploy a java webstart app per-machine?
Is there a way to share the same cache folder between all the users on the network so they see all the same settings?
Does anyone have similar experiences and suggestions on how to better deploy jnlp applications?
Thanks for reading.

To pre-install you can use the -import option.
Something like
javaws -import -silent http://whateverTheServer.ext/whateverTheJnlp.jnlpYou could even copy all files to a local server and override codebase with -codebase option.
You could try (but I've heard people complain about it) to use the -system option so that all machine users run same instance (app is installed once per machine, not once per user and machine).
About properties, the most common way to store data is to put them in the user.home dir, have a look there, maybe you can spot out a file (or a directory) and just tell user to copy their setting on a USB drive and paste them (into user.home) on any other machine they're gonna use.
Bye.

Download .jnlp file when first time

Hi Everybody,
I am new bee for java web start.
We are having swing application which we want to distribute through Java Web Start. Client can run application through provided web link. we also want to download .jnlp file to the client machine when user clicked the link first time.
I go through different thread for the above problem in this forum, but though not getting clear idea as in our application, we need to generate dynamic .jnlp file. All solution posted for the above problem assuming that .jnlp file exists at some location, but in our case we have to generate it when user clicked it first time. Any body having some idea ?
Our second problem is, can it possible that user will run the swing application only when he click the link provided on the web server ? In our case authentication of user is done in our web application and when user will click the provided link user id and other information will be pass to swing application as parameters through .jnlp file. If that application will available offline user can run it through last downloaded .jnlp file without clicking the link , which will be not allowded. Also we are concern about multi user environment, as we are thinking to dynamic generation of .jnlp file , it may possible that other user running the same application noted .jnlp file version difference and will download the .jnlp file of other user ?
Can any body have any idea, how can we done the above scenario ?
Thanks in advance,
Dimpal

If you upgrade to Java 1.4.2 it will present a dialog asking for desktop
integration the first time you start the application.
Maybe that's what you want?

Deploying FX as a Desktop App - jnlp file codebase should be...what?

Howdy,
If I try and run my deployed JavaFX app on another PC I get an error pointing back to the codebase that NB created in the <appname>.jnlp file:
codebase="[http://localhost:8082/servlet/org.netbeans.modules.javafx.project.JnlpDownloadServlet/E%3A/JavaFX/Projects/Concentration/Concentration11/dist/]"My main question is, for a standalone desktop FX app you want to distribute, what should the codebase be?
I assume you don't point to your developer machine's URL because of course that won't exist on someone else's machine. And unlike most web examples, this won't be running from a server.
Many other examples refer to running the jar file from the command prompt - not acceptable if you are selling an applet, or even just distributing to the general public.
So how does this work - how do you set up the jnlp file for desktop deployment? And, do you have to manually do this, or is there something I am missing in NB (6.8) ?
Many thanks in advance.

Hi Phil and thank you. I admit have been avoiding learning to compile from the command prompt or with other tools due to the ease that NB affords - but it seems that NB is introducing some issues lately.
I haven't tried the other tools yet, but I thought maybe I could just edit the NB created jnlp file:

Is this the intended behaviour?

How to deploy a file on all users C drive via group policy

I'm trying to deploy a file on all users C drive via group policy but its not working. logon script is already kept in place but nothing is happening. If I run the same command from my pc it's working fine. Does any one have good script to copy & deploy
the file. Pls help

Hi,
You can use Group Policy Preferences to deploy this and Item-level-Targetting to filter by OUs/groups, wmi filters ,etc.
Computer Configuration / User Configuration - Preferences - Windows Settings - Files

Getting problem during deploying desktop application with JNLP File.

Hi,
I am developing one standalone (desktop) application in swing. I want to make one jnlp file that would be install on my computer as a client(suppose). When i am doing jav web start enabled after that making application descriptor. But when i am running a web browser where i have stored my html file. but it is giving me an error that codebase or something like this. Please tell me is there any other way to do this task. Please help me to do this. Is NetBeans ide is best way to do this. please help me.
Thanks in advance.
Manveer.

>
...but it is giving me an error that codebase or something like this. ...>Try changing the JNLP file to 'something like that', that might work.
In case it does not, I provide a tool called JaNeLA that will provide a lot more specific error message(s) than 'something like this'.
Really, I cannot see you getting better help than on some of your other recent threads, with vague, unspecific error messages, and without putting the JNLP file and other relevant information.

Indicated instalation path of the aplication in JNLP file

Hi everybody,
First of all, i would like to apologize about my english. Sorry about it.
I got a problem with a deploymet of an application using Java Web Start.
My application deploys correctly but i need a way to indicate where's the path i want to download the app.
I've been read all documentacion about it but the argument productpath of the JNLP file doesn't works.
I try a lot of differents ways in JNLP file, like:
<application-desc main-class="MyPrincipalClass">
<argument>-java</argument>
<argument>-productpath</argument>
<argument>DownloadedPath</argument>
</application-desc>
But any of them work.
I need a way to indicate where the app must be downloaded when JNLP file is executed.
Thanks in advanced.
Regards from Isaac.

..the boss would like to have the possibility of decide
where the application would be installed (for example: c:/MyApp/).Win XP?Start | Settings | Control Panel
Java
General (tab - default)
'Temporary Internet Files' Settings.
'Location:' ChangeThis is how the end user (or their system administrator)
can choose the installation location for Java Web-Start
applications.
Explain that to boss, and the end user, and I think
they will be far less interested in the application
itself offering an independent installation path.
(after all - If I want my JWS apps. to be stored
on the 'shared data' drive, I do not want to have
to configure it for every single Web Start app. -
just the plug-in - once)
I've seen that this could be possible using
productpath property in JNLP but this doesn't work.Huh? I do not know what you are refering to.
Can you provide a net reference for 'productpath'?
If chossing installation path it's not possible, ...It is (ultimately - though I want you to talk your
boss out of such nonsense), as mentioned by
Orclev using an 'installer' element - but that will be
at the loss of a lot of other functionality (also as
mentioned).
i'd like to know how can obtain (during the
downloaded process) the path where the
application is being installed. Still not convinced the app. needs it, but on
that matter, is your application running in
a trusted environment? It is far easier to
determine app. classpath if that is the case
(in fact I am not sure it can be done in an
untrusted app. - and that might be a security
problem).

Jnlp file shown as XML in Internet Explorer

My problem is somewhat complex and have given me a headache while it seem to be a completely erratic behaviour. (Erratic, not over time, but over different computers.)
The main trouble is that I've got two separate webservers serving jnlp files for a production and a test environment. A user can access both servers and there no troubles finding and clicking at jnlp-files. There is however troubles while the jnlp-files in the test environment are shown as XML ("xmltext" in the Internet Explorer way) files.
But only when using Internet Explorer. The problem do not occur when using Netscape and never in the production environment (webserver).
I've triple checked the mimetype configuration of both the webservers and they are ok.
The result of a "get", from both webservers, is (except for the timestamps):

The client computer is running Win2000, Internet Explorer v5.50 and a newly installed JavaWebStart.
Well, there are more to it. This behaviour is for some users at the company. There are users that can, with no problem, run the application deployed at the webserver in the test environment.
A user who can not load jnlp-files in the test environment using his computer, can be able to load the program at another computer as he logs in.
Is there anyone who can help me out with this one?
How come the user(s) at a computer (and one login account) have different Internet Explorer behaviour when getting a jnlp file from two seperate webservers (using same webserver mime setup) when other users (computers) don't?

I've seen a lot of messages concerning the response of the webserver in posts of this JWS&JNLP forum. Some people gives the advise to use telnet to get the server response. I've used this code (based upon some free sun code in some tutorial trail I think it was).

How to load .jar files when not specified in the .jnlp file

Hello,
We are deploying an application with JWS but due to the nature of this app, we need to download additional jar file only when the user has been authenticated. The jar file(s) we need to download can hardly be predicted (in term of name) and thus cannot be all listed as lazzy resource in the .jnlp file.
However, we would like to take advantage of the various JWS features relateed to .jar download and cache and would prefer not to reinvent the wheel by implementing our on stuff (i.e. URLClassLoader with caching etc.).
Any idea, suggestion?
Thanks in advance.
Fred.

How about writing a second jnlp file with the optional jar listed in it and running it only if your user is authenticated?

Java 1.6.0_05 does not recognize first and last property in jnlp file

Hi
Has anybody else seen this?
The jnlp file contains five properties, but the JRE does not recognize the first nor the last property.
It has been working great since 1.4.2, through 1.5 and 1.6 until 1.6.0_05.
<property name='bog' value='%2fdata%2fkirkeboeger1892%2f'/>
<property name='opslag' value='aa001/AB/007/0000a-A.Jpg,aa001/AB/007/0002a-F.Jpg,... </property>
<property name='sessionId' value='ed0l5n55yu2h04alvqxdpbn3'/>

We also have this problem, but it's not first and last property.
We have 6 properties, and the 3. property is gone.
If I download the jnlp file, the property is there, if I choose show jnlp file in "javaws -viewer" it's not there. Only difference between this property and the working properties is length.
The length is char 255, and the data is base64 encoded.

Anyone any ideas?

Can anyone tell me how to do a system level deployment using JNLP ?

Hi All,
Can anyone tell me how to do a system level deployment using JNLP ?
Any example or link will be very useful.
Thanks in advance..

Thanks for the link. I can now able do configure on system level.
Uniform for all users.
However, I have three different environment running ( e.g : production, uat and dev )
And I want to deploy all of them on system or enterprise configuration.
I create the file "deployment.config" on jre/lib directory and put the entry as below :
deployment.system.config=file:/E:/Deployment/XXXX/production/deployment.properties
deployment.system.config.mandatory=trueNow, when I run other environment it will look on the production deployment. I have different
version of jars for production , uat and dev.
How can I archive that ? I want different universal "cache" of jars for all the three different environment.
e.g ( production - in one loaction for all the users , C:\Documents and Settings\All Users\Application Data\prod\cache
uat - in one loaction for all the users , C:\Documents and Settings\All Users\Application Data\uat\cache
dev - in one loaction for all the users, C:\Documents and Settings\All Users\Application Data\dev\cache )
Is that possible ??
Thanks in advance,

Using DRS to specify Java version when executing JNLP file.

We have an application that executes from a JNLP file that we are told is version sensitive. We have a rule set created for a number of apps that work just fine to meet this goal. However, when creating a rule to execute this JNLP application we are having issues getting it to work. To simplify the process we created a certificate hash rule for this application and when reviewing console\trace we can see it correctly identifying and executing under the Java 6U29 environment. The issue is that even though 6u29 is being invoked it does not work (merely displays a "application error" message). However, if I instead launch the JNLP file using the Javaws.exe in the 1.6.0_29 folder the app loads fine. When comparing behavior with the rule set environment and a 6u29 only environment I saw some peculiar entries.

So it appears that the 6u29 version of Javaws.exe is getting called however some of the configured paths are being set to the 8u25 path. Not sure if its a cause but does seem to be relevant since on the exact same system if I run the JNLP specifically with the 6u29 exe it works as expected. Any assistance would be appreciated.

..how do I specify a specific range of JREs in the jnlp file so that JWS picks up a JRE from that range only? So if 1.5.0_07, 1.5.0_17 and JRE 6 are installed, it should run the app on 1.5.0_17.From the JNLP Specification
*4.6 Java Runtime Environment*
Several JREs can be specified, which indicates a prioritized list of the supported JREs, with the most preferred version first. For example,
    <java version="1.3" initial-heap-size="64m"/>
    <java version="1.2">
      <resources> ... </resources>
    </java>So your app. would need more along the lines of..
    <java version="1.5.0_07 1.5.0_08 1.5.0_09 1.5.0_10 1.5.0_11 1.5.0_12 1.5.0_07 1.5.0_13 1.5.0_14 1.5.0_15 1.5.0_16 1.5.0_17 " />
    <java version="1.6+" />Actually you'd need the list of 1.5 versions reversed. Well, you get the idea hopefully. For more on versioning, see my [JWS versioning page|http://pscode.org/jws/version.html].

Jnlp file

I have some software that was coded for Java 1.5 and since updating to Java 1.6 it gives an hs_err_pid<pid>.log on the desktop of the user.
The source code is not available but the problem does not stop the software working only stops it from closing gracefully so what I was hoping to do was move the error log from the default on Windows of writting to the desktop to writting to another location.
I ahve found the command -XX:ErrorFile=./hs_err_pid<pid>.log that works from the java command line. This software is deployed using a JNLP file and I would like to get Java to write the error somewhere more subtle than the desktop.
Does anyone know if this is possible?

Thanks for the suggestion. I tried the test.jnlp, but it still did not work. I also was not sure what was meant by:
4) Do the following in c:\test\bin
javac test.java
jar cvfm test.jar manifest.txt *.class
I should also mention that I had everything working before, but the jnlp file was only running the oldest jar file no matter what I did (delete the old jar files and put in a new one, etc.). I tried deleting stuff manually from the cache on the c: drive and now nothing happens at all. Could it be a bug?

Web Start : JAR resources in JNLP file are not signed by same certificate

What does this error mean exactly?
All the jars in this JNLP file are signed by the same certificate it's just that some of them are also signed by another certificate.
According to this closed/fixed bug : http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4928787
Web Start should not be rejecting jars due to multiple signers???
Is this a regression in 1.6? or was this never actually fixed?
I can make this work by not signing these 'presigned' jars and putting them into extension JNLP files but this is less than desirable.
Some reasons for not using the extension JNLP:
-- Avoid this bug (which is also marked closed but not fixed) --> http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6566071
-- I would like to sign all the jars I deliver with my own certificate.
-- I would also like to give my clients the ability so sign the jars themselves (their own certificate) after they certify the application for distribution throughout their organization.

Thanks for responding.

Can application know the location of its most recent cached *jnlp* file?

Can an application know if it was launched by clicking on the hyperlink in a web page, or whether it was launched from the shortcut on the desktop?
Alternatively, Can the application know the location of its most recent cached jnlp file on the desktop?
To take a specific example, let's say I have a word processor, My Word that is deployed using Web Start. It can view documents on the web and must also work offline to view local documents.
When a user clicks the hyperlink to the doc, say,
myParty Open the myParty document
then myParty.jnlp launches My Word, opening the myParty.txt file.
Since there is no way to pass arguments dynamically, one must have a jnlp file for each doc.
So myParty.jnlp has the url of the doc hardcoded in it.
<application-desc main-class="MyWord">
<argument>http://www.MySite.com/myParty.doc</argument>
</application-desc>
The problem is that apparently Web Start uses the most recent jnlp each time it is launched.
So that if the file has moved, or if one is offline, then the application hangs because it is trying to open the same document, regardless of whether MyWord was launched by clicking on the hyperlink in a web page - in which case this would be appropriate - or whether it was launched from the shortcut on the desktop - inappropriate here.
As a workaround, I was wondering - where is the jnlp file stored on the local desktop?
If the application could find the most recent jnlp, then it could rewrite it (after it was opened the first time) with an identical jnlp that has no application-desc arguments.
Then when the user runs from the shortcut on the desktop, it will launch without a document to open.
Any help appreciated.
thanks,
Anil Philip
Are you planning to kill yourself? Stop! listen to this song

1) To make it more complicated, it seems that the browser also does the caching.
2) I could not find the jnlp as a file on the desktop, so I suspect that is stored in some database. Is there any way the application can write to it or any api to simply allow the application to change the arguments?
3) It is not an option to use jnlpservlet as the document can be placed anywhere and not just on a webserver under our control.
