Web starting jnlp files w/out access to Internet

I am writing a JavaFX program and am running into difficulties when trying to run from a browser since the created jnlp file is trying to access files from the dl.javafx.com website. Why are the javafx-rt.jnlp and other files like dtfx.js not part of the JavaFX download? Is it possible to get a download of all the jnlp and js files needed to run on a detached network?

Don't know much about JavaFX, but if a standard (meaning 'online') JWS can download everything needed then any browser can do just the same.
Go home, download the main jnlp (use the magical 'Save As...' function) and any pointed resource, change jnlp's codebase, put everything on your server and it's done, plain and simple.
Even easier: whatever your app does I'm preatty sure it can work as a stand-alone app, so you already have any jar you may need.
Bye.

Gerald,
a couple of comments on the FAQ regarding
Q: Can I use JWS for Intranet apps?
file:/// works where file:// doesn't
also including the path to the .jnlp file in double quotes allows to use path containg empty spaces.
example:
javaws "file:///C:\Program Files\Java Web
Start\.javaws\cache\http\Dlocalhost\P80\DMclient\AMdemo.jnlp"

Java 7 Update 25 Client App Downloaded From Web Start Can't Connect Out

Since Java 7 update 25, I have an issue where my client Java application, downloaded with Java Web Start, can no longer connect to a remote server. (The client uses remote EJB to connect various servers). The issue I believe is that the client application is being blocked by security features of this Java update.
A very quick (random?) fix around the problem is to show the Java console. If the Java console is enabled to be shown, the client application can connect fine.
Although showing the Java console is a quick fix, it's not one we particularly want to keep asking customers to do. I understand we may need to define the Codebase and Permissions in the manifest file as described here: http://docs.oracle.com/javase/7/docs/technotes/guides/jweb/no_redeploy.html..
I have defined the Codebase and Permissions in the manifest of the client jar's we build ourselves. I believe this has worked as we no longer see "Missing Codebase manifest attribute for...." in the console for our own jar's. However, the application still cannot connect out. I'm stumbling around somewhat on this issue and trying various things in an attempt to get this to work. Assuming i'm on the right lines and the problem is some jars missing the Codebase and Permissions in their manifests, my question is, should I and how can I modify the manifest of 3rd party jars to include this information? For example, the client app requires many JBoss and EJB client jars - do I need to somehow modify the manifest of all of these jars to include the codebase and permissions?
It goes without saying that all the jars are signed - the application would not start at all if there was a problem here. So the application starts with it's login box - but it simply cannot connect out to the servers.
If anybody can offer any help on this issue i'd be most grateful. As a quick fix, is there a way to get this to work via adjusting Control Panel settings (other than showing the console)? I have played with a lot but not stumbled on a way to get this to work other than showing the console, although ideally i'd like to be able to get this to work without having to do any tweaks to clients Java control panel.

We're also seeing this. The 7u25 update completely derailed a trial program we were conducting, because no one could log in to our application via WebStart once they upgraded Java.
Our login code crashes because SwingUtilities.isEventDispatchThread() throws an NPE.
We tried theskad81's fix but it didn't work for us. We worked around the issue by hosting u21 on our site and pointing our WebStart page there instead of at Oracle's update site.
*** ORACLE: PLEASE FIX THIS ISSUE USING APPLE'S FIX (mentioned in an earlier post - see above) ***

Java Web Start (JNLP) getResource return null.

I have a Java Web Start Swing application and with the Java version 1.6.0_u27.
same code run from jdk1.1.8 to jdk 1.6, more then 10 customers it's work fine, java web start only run on jdk 1.4.0 and jdk 1.5.0.
just migrate one customer from Java version 1.5.0_u6 to 1.6.0_u27.
sometimes, the getResource will return null, when system return null, then system cannot get any other resource, always return null.
It only happen in Java web start environment, work fine in command line (java/javaw), and same as the WebStart loses resources post,
"Unfortunately this cannot be reproduced easily. Sometimes this happens after some minutes, sometimes the application can be used for days without problems.",
note. all of my resource files put in the same jar file, one resource file in that jar get fail, all files will be fail.
after I get the url, I will use new BufferedInputStream(url.openStream()); to retrieve data, never use the File object.
for example, get resource from "/path/a1.xml", "/path/a2.xml"....... 30 minutes pass, get same file "/path/a1.xml" will return null, then all resource will return null.
URL url = getClass().getResource(s);
if(url == null) {
System.out.println(getClass().getResourceAsStream(s)); // also null, log only
// if the url == null, the following retrieve will be null
url = Thread.currentThread().getContextClassLoader().getResource(s);
if(url == null){
System.out.println(Thread.currentThread().getContextClassLoader().getResourceAsStream(s)); // also null, log only
ClassLoader loader = getClass().getClassLoader();
if(loader == null){
loader = ClassLoader.getSystemClassLoader();
if(loader != null) {
System.out.println(loader.getResourceAsStream(s)); // also null, log only
url = loader.getResource(s);
if(url == null) {
System.out.println("URL resource still can not found!!" + s);

I ran into the same problem with JNLP and IE.
Here is the trick I am using to make IE think that it is dealing with "real" .jnlp file. This works on JBoss-3.2.1/Tomcat-4.1.24 bundle.
In web.xml:
<servlet>
<servlet-name>fakejnlp</servlet-name>
<description>jsp that generates JNLP on the fly</description>
<jsp-file>start.jsp</jsp-file>
</servlet>
<servlet-mapping>
<servlet-name>fakejnlp</servlet-name>
<url-pattern>/start.jnlp</url-pattern>
</servlet-mapping>
Now, when you request start.jnlp (perhaps, with HTTP parameters), you end up executing your start.jsp. IE is happy. One limitation, though: if you need to pass parameters, there should be no href attribute in <jnlp> element.

Deploy Forms 10g applications using Java Web Start (JNLP)

I wonder if anybody can help me out to use WebStart for my Oracle Application . Currently our application is running using Jinitiator.recently i got to know that webstart is another method to run webforms as just as Client/Server ,am not able create an exact JNLP file and i could't see much posts related to this.
Thanks & Regards
Najeeb.M

You can avoid extra windows simply by setting separateFrame=false in the formsweb.cfg. Another helpful tip, if your page does not contain any extra html, is to set the height and width as follows:
HEIGHT=100%
WIDTH=100%
This will cause the applet container to use all available browser window space. It will also cause the applet container size to dynamically adjust if the browser window is resized. This tends to create a more professional look-and-feel.

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):
HTTP/1.1 200 OK
Server: Netscape-Enterprise/4.1

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).

Not getting System.out.println output in Web Start Log File

I am new to this but I'm running through the examples in Mauro Marinilli's "Java Deployment with JNLP and WebStart" and the install-win and install-win2 examples are not writing properly to a user-specified log file on my desktop (chosen location). I have several versions of j2re/jre installed on my client computer and have started several of the javaws.exe files on my computer to specify that I wish to Show Java Console and Log Output but
1) no Java console pops up when I subsequently run the JNLP from my web server
AND
2) no log file is written
I do see the batch file left in place for install-win2 so I believe that the application is being run (such as it is... lol)...
Any ideas what the problem might be? All reasonable suggestions (i.e. not PEBKAC) welcomed...
Regards

How about in Solaris?
May I use the similar method to redirect the stdout to a specific file? What is the syntax for this?
Or, I can only start server with interactive mode (without watchdog) and use ">" to redirect the logs?
Thx a lot.

Error on starting jnlp file: .."error recv"

Hallo,
when trying to start a Webstart application on my laptop, the following error messages appears:
"Entrance screen: *Error recv*" (translated from German)
"Eingangsbildschirm: Fehler recv" (original message)
Screen shot: [http://tobsefritz.de/files/screenshot_java_error.jpg]
It happens on every webstart file. Also official Sun files e.g.: [java.sun.com/javafx/|http://java.sun.com/javafx/]. But the problem is never permanent. After trying to start it about 6 times it runs without errors. But I have no thought for the reason.
I updated from Java JRE version 1.6.0_7 to 1.6.0_11 and then to 1.6.0_12 without improvement. I also cleared cached Webstart data.
My system:
Windows Vista Home Premim 32 Bit
Java(TM) SE Runtime Environment (build 1.6.0_12-b04)
Java HotSpot(TM) Client VM (build 11.2-b01, mixed mode, sharing)
2.1 GHz

Laptop
Best wishes,
Tobse

Is it your home computer or some work-enterprise-firewalled-noCmdPrivilege-lotOfSafetyProcessesRunning one?
I've seen enteprise policies cause any kind of trouble; the best one is a 'missing ;' scipt-engine-message on every start, still unresolved but not blocking (we just told the users to press 'OK' and stop calling HD).
The right translation is 'Splash: recv failed', you can google for it. For instance I found results about Comodo firewall like this rather than about Panda Antivirus like this .
Next time you need to translate something go to ProgramFilesDirectory /Java/jre YourVersion /lib/deploy/messages_YourLanguageISOcode .properties see property name and look for it in messages.properties. In a nutshell: messages use I18N.
Bye.

How to get access to the local file system when running with Web Start

I'm trying to create a JavaFX app that reads and writes image files to the local file system. Unfortunately, when I run it using the JNLP file that NetBeans generates, I get access permission errors when I try to create an Image object from a .png file.
Is there any way to make this work in Netbeans? I assume I need to sign the jar or something? I tried turning "Enable Web Start" on in the application settings, and "self-sign by generated key", but that made it so the app wouldn't launch at all using the JNLP file.

Same as usual as with any other web start app : sign the app or modify the policies of the local JRE. Better sign the app with a temp certificate.
As for the 2nd error (signed app does not launch), I have no idea as I haven't tried using JWS with FX 2.0 yet. Try to activate console and loggin in Java's control panel options (in W7, JWS logs are in c:\users\<userid>\appdata\LocalLow\Sun\Java\Deployment\log) and see if anything appear here.
Anyway JWS errors are notoriously not easy to figure out and the whole technology in itself is temperamental. Find the tool named JaNeLA on the web it will help you analyze syntax error in your JNLP (though it is not aware of the new syntax introduced for FX 2.0 and may produce lots of errors on those) and head to the JWS forum (Java Web Start & JNLP Andrew Thompson who dwells over there is the author of JaNeLA).

Dynamic JNLP - displaying using java web start

Hi,
I am creating a dynamic JNLP in a servlet at the server side. Please see below.
String someJnlpString = "<?xml version=\"1.0\" encoding=\"UTF-8\"?> \n" +
                                            "<jnlp .....    >    </jnlp>";
        String attachment = "inline; filename=\"launch.jnlp";
        String ct = "application/x-java-jnlp-file";
        OutputStreamWriter out = new OutputStreamWriter(response.getOutputStream());
        response.setContentType(ct);
        response.setHeader("Cache-Control", "max-age=30");
        response.setHeader("Content-disposition", attachment);
        out.write(someJnlpString);{code}
Then in my JSP, I am trying to open this JNLP by using the following code
{code}        window.open('servlet/DisplayImage?arg=first-arg");The exception that I am getting is JNLParseException could not parse launch file. Error at line 0. If I open the downloaded file then its working.
Can somebody please advise me how can I directly open that JNLP from the servlet by using java web start?
Thanks a ton,
Subhash

I am able to run it now after clearing the java cache

Calling JNLP file via Servlet

Hi Folks,
I need to pass runtime parameters to my jnlp file from URL param, like ?requestNum=12345&mergeId=1.
So I created a Servlet to process the request and add the requestParams at runtime in the JNLP file,
In the doGet Method I have teh following piece of code,
String[] args = new String[]{"requsetNum",request.getParameter("requestNum"),"mergeId",request.getParameter("mergeId")};
response.setContentType("application/x-java-jnlp-file");
PrintWriter out = response.getWriter();
//It writes the jnlp content prperly in console, System.out.println(JnlpFileContentBase.readBeforeArgElementsContent()+JnlpFileContentBase.populateArguments(args)+JnlpFileContentBase.readAfterArgElementsContent());
//I split the jnlp file content before and after the argument area out.println(JnlpFileContentBase.readBeforeArgElementsContent()+JnlpFileContentBase.populateArguments(args)+JnlpFileContentBase.readAfterArgElementsContent());
out.close();
But when i run on server the above the jnlp is not starting up,
Am i missing something in the doGet method? is the PrintWriter out object is enough to write back the content?
Please help me to find out what am missing out here.
Thanks

Hi Andrew,
Thanks for notifying that, but that due to my testings with several combinations, I copied the file and kept direcly under WEB-INF and under the webapps/ElemFinder and several places to see it could be retried or not. And hence copied one of the errors. Nothing worked btw.
I suspected initially it could be because of calling another jnlp file, but now i have my consolidated single jnlp file, but still have the FileNotFoundException for the jar file I have,
sb.append("<jar href=\"WEB-INF/org.eclipse.equinox.launcher_1.0.101.R34x_v20081125.jar\"/>\n"); // code from Servlet
This is the firs jar resource under the resource elements
Where I get the Exception,
java.io.FileNotFoundException: http://localhost:8080/ElemFinder/ElemFinderEngineInvoker/WEB-INF/org.eclipse.equinox.launcher_1.0.101.R34x_v20081125.jar
I think its basically issues with reading the resource files,
I tried with several options for this file either, placing under WEB-INF, under webapps/ElemFinder ... etc. Nothing seems to be working,
Any entries to be put in web.xml for this?
Pls help me to get rid of this....
Thanks
Subash
PS: BTW i dint try in teh util u gave sice the jnlp already is downloading from my App, do you think still needed to check in the util?

How to debug java web start with jdk1.5?

i want to debug a JWS app with eclipse, not java console, so I follow Unofficial Java Web Start/JNLP FAQ(http://lopica.sourceforge.net/faq.html) and still not worked.
the attached session worked at first and broke soon, and I found some idea from Unofficial Web Start FAQ Update/Errata(http://lopica.sourceforge.net/update.html). I did the following:
set JAVAWS_TRACE_NATIVE=1
javaws http://localhost/test/test.jnlp
copy command line from popup window.
add "transport=dt_socket,server=y,address=7000" to command line:
C:\progra~1\Java\jdk1.5.0_03\bin\javaw.exe -Xrunjdwp:transport=dt_socket,server=y,address=7000 -Xbootclasspath/a:C:\progra~1\Java\jre1.5.0_04\lib\javaws.jar;C:\progra~1\Java\jre1.5.0_04\lib\deploy.jar -classpath C:\progra~1\Java\jre1.5.0_04\lib\deploy.jar -Djnlpx.home=C:\progra~1\Java\jre1.5.0_04\bin -Djnlpx.splashport=4362 -Djnlpx.jvm="C:\progra~1\Java\jdk1.5.0_03\bin\javaw.exe" -Djnlpx.remove=false -Djava.security.policy=file:C:\progra~1\Java\jre1.5.0_04\lib\security\javaws.policy -DtrustProxy=true -Xverify:remote -Djnlpx.heapsize=NULL,NULL com.sun.javaws.Main http://localhost:8080/test/test.jnlp
the debugger still gets detached. I don't know what's wrong.
JWS has come out for many years, I still found so many undocumented skills, even netbeans5 doesn't support it. Sun want to give up java?

Try checking out this other thread, particularly the reply from dietz333 (I happen to know he's a regular genius when it comes to JavaWS):

Java web start and .JRXML

Hello everyone.
I have an application form calling from browsers from client side using Java web start (JNLP) and applications has one report (.jrxml file) which is placed at server. I could start application form from client browsers but at the time of executing report it does not respond. There is no message , I think does not find path of where .jrxml file is placed. Can any one help me. Pl. note that reports get executed when users presses button on form.
With thanks !
