Does Netscape Enterprise Server support Java Web Start?

Hi,
I working on this problem too. Could you send me about
your project's details ? (spec and config)
My email: [email protected]
Thank you.I've come to the conclusion that Java Web Start does not support hosting applications on password protected servers. It plain does not not work.
If anyone can get it to work, please let me know.
For me the JWS version based servlet is not a hosting option. I'm stuck with a dumb old IIS server. The only reason I'd want to use the version based servlet hosting is to work around the update bugs.
See my other recent postings.
I've posted a bug-report on the bugparade, but it will take three months before I should expect a reply.
At that point, they may dismiss the bug-reports as "intended features", in which case I do wish there was more options to "turn off" "features" in the JNLP file. ;-)
For now I've been my client has accepted "security by obscurity" for the beta version of the program I'm working on, i.e. I've put the program in a "secret" place and turned off password protection.

Java Web start and CR

Has anyone been able to use CR with Java Web Start? If so, please share your experiences. I have not been able to find any info on this. I guess the most fundemental question is if CR supports the web start model. Thanks, FR 

CR doesn't officially support Java Web Start.I've heard of a few people doing it in the past. I haven't actually done it myself yet.From the feed back I have recieved the trickiest thing is making sure that the supporting properties and XML files get placed in the proper class path.CRConfig.xml needs to be in the root of the classpath.If you can get that working I believe everything else is fairly easy.If you have trouble with that. You might try putting it in a JAR file and including it with the other libraries. Rob Horne <a href="/blog/10">Rob's blog - http://diamond.businessobjects.com/blog/10</a>

Not getting application in Java Web Start

Hello Sir,
I wanted to run an application using Java Web Start. So, I created a jnlp file and i have mentioned the necessary jar files and the main class file. when I clicked on the jnlp file, the application is running in the Server using Java Web Start and its shortcuts are creates on the desktop and in the startmenu. I am able to run the application by clicking on the shortcut in the server. But I am unable to Download the application in the Java Web Start. It is not showing any Error Messages and the application is not running in the cleint machines.
The contents of the jnlp file is as follows.
<?xml version="1.0" encoding="utf-8"?>

"I am unable to Download the application in the Java Web Start"
If webstart in not actually downloading the jar - is the jar in the correct location?
Is the server named dev01 and the directory structure actually /Dummy/New?
Note: you do need to set up the mine type JNLP on your server,
In my case the location of the JNLP file and main jar file passport is in the following directory.
c:\Inetpub\WIMRoot\application
The additional jars are in
c:\Inetpub\WIMRoot\application
I hope this may give you some clue

How to convert existed standalone APP to java web start app?

hello:
I didn't find useful information about how to convert an existed java
app into app which can be launched using java web start from the sun java developer's guide.
I have designed a simple java applcation and want to lauch this program with
java web start techniques(on local machine only). Is there any easy way that i could convert my program to the one which support java web start, so i can double click the *.jnlp file to launch my java applcation.
thank you

Java Web Start Application surprisedly does not start anymore based on new JRE1.7.0_45

Hi everyone,
we have to maintain a self-developed Java Application which is running based on JRE1.5.0_51 (x64). Our recent client machines have JRE1.7.0_40 (x64 too) installed in addition to the mentioned (and needed) JRE1.5.0_51 (x64).
Everything was fine up to the point where we tried to install the newest JRE1.7.0_45 (x64) as the new version for doing the web start magic. The result is that our application (which is/was unchanged!) does not launch anymore. The strange thing is that we do not get any StackTrace, Exception or something else like this.
The startup process simply hangs :-(
Nothing has changed (application itself, firewall, network settings, hardware) apart from the new JRE version. It's reproducible at will. If I install JRE1.7.0_40 (x64) the application starts, if I install JRE1.7.0_45 (x64) the application hangs.
I can say for sure, that in both cases (*_40 AND *_45) Web Start is able to do the synchronizing job and to launch the application base on the correct JRE1.5.0_51 (x64).
My guess is that in case of an installed JRE1.7.0_45 (x64), the application hangs when it tries to connect to the database (Oracle 11g) via JDBC.
I found a little hint in the Web Start Console. Therefore I had to switch the trace level of the console to 3 (which includes security, network and basic)
In case of an installed JRE1.7.0_40 (x64) - which leads to a running application - I will receive the following output:

These last "network:" log entries will never stop. This will lead to an infinite loop which results in a great memory leak. I have to kill the process via windows task manager in order to get rid of it.
Does someone out there has the same problem? Are there any new additional security issues which prevent my client to establish the database connection on port 1521?
Any other ideas?
Thanks in advance for any hint on this issue!
Regards,
Alex

Resolution: We still were not able to solve this issue! The only way to get out of this is to install the JRE1.5 as the x64 variant. In this case no switching from 64-bit to 32-bit is needed and everything is on track again.
But this is still strange and unexplainable :-(

Why Java Web Start doesn't support Pack200 out-of-the-box?

Hello All,
Why Java Web Start doesn't support Pack200 out-of-the-box? I was hoping that Java 6 would make things easier by adding direct support for Pack200 in Java Web Start and JNLP without needing to use servlets, etc.? All my clients are Java 5 or above so I can't push the Pack200 compressed version of the jar to every single one of them and there is no selection process needed. But I can't do it because of the servlet or complex Apache server setup requirement (it would be a headache to get customers' web server admins to set up Apache or whatever web server that way).
My question is why is there unwillingness to add Pack200 support directly to Java Web Start and JNLP so that you can start Pack200 compressed jars just like you would start any jar using Java Web Start? Is te a technical problem?
Thank you,
Mete Kural

Hallo,
I didn�t try it, but the webstart FAQ�s read:
Can I use Pack200 compression with the JnlpDownloadServlet?
Yes. The JnlpDownloadServlet distributed in the samples directory of the JDK now supports Pack200. If you deploy yourfile.jar along with yourfile.jar.pack.gz the packed file will be downloaded when the client is running Java Web Start 1.5.0 or later.
http://java.sun.com/javase/6/docs/technotes/guides/javaws/developersguide/faq.html#217
For further information you may want to look at
http://java.sun.com/javase/6/docs/technotes/guides/javaws/developersguide/downloadservletguide.html#pack200
The configuration of the server and the the servlet (as described in the second link) is as easy as it seems.
I got it working on the first try and it was my first experience with websevers at all.

How to add Java Web Start MIME type to Sun Java SYstem Application Server?

Hi,
In the process of learning about Java Web Start,
I read in the document that I had to add "application/x-java-jnlp-file JNLP " to a configuration file.
Does anyone know where that file is for Sun Application web server( vesion 8, on WIndows)?
Thanks,
Sun

I believe you can add it to default-web.xml file located in your server config dir.
(i.e. /opt/SunAppServer8/domains/domain1/config/default-web.xml)

HT5559 Java web start does not work

I have followed the instructions in this article, including the last step about web start, but it still does not work, neither applets or web start. When I try to launch a JWS application by double clicking it I get the dreaded warning dialog:
To open this Web Start application, you need to download the Java Runtime Environment.
Click “More Info…” to visit the website for the Java Runtime Environment.
I do have a JRE installed, 1.6, since I for compatibility reasons can't upgrade.
Trying to launch a web start application from the commandline looks like this:
$ javaws /tmp/airview.jnlp
Java Web Start splash screen process exiting ...
Can not find message file: No such file or directory
Regular Java-programs work fine.
$ java -version
java version "1.6.0_37"
Java(TM) SE Runtime Environment (build 1.6.0_37-b06-434-11M3909)
Java HotSpot(TM) 64-Bit Server VM (build 20.12-b01-434, mixed mode)

Read this thread https://discussions.apple.com/thread/4789691?tstart=0
This fixed the issue for me:
sudo /usr/libexec/PlistBuddy -c "Delete :JavaWebComponentVersionMinimum" /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/XProtect.meta. plist
In the comments to the linked article someone suggests to comment out the node in stead of deleting it. Probably safer (it's explained further down how to do that). Anyway I already spent to much time on this nonsense, deleted it and it worked, so I'm happy.

Does messaging server support java?

Hi,
Anyone know that does the messaging server bundle's web server support Java? Can I run jsp on that web server?
Thanks

Hi,
Which "webserver" are you referring to?
The mshttpd daemon that provides webmail access (messenger express) is not a full-blown webserver software. It is only designed to provide access to store information. It will not run random java files or whatever.
The webserver that you can use for UWC IS a full blown webserver, with the UWC instance being one container - so as to it's capabilities, you should look up the webserver 6 documentation on docs.sun.com.

Shane.

How can I upload a file to the server where I save the Java Web Start Files

Java Web Start does not start

Hi,
This is a quite simple question I suppose, but I can't figure out the solution.
When starting my application using Java Web Start 1.0.1_02 the JWS application handler does not show up. JWS does only show a splash picture, then it disappear after 10-15 seconds. No error is written in the Java console window.
No errors occurred when installing JWS and it seems to be correctly installed, and JRE 1.3 is installed. I have successfully used my JNLP file earlier when I had JWS installed. After re-installation JWS does not work.
What is the error?

The two most likely problems are java version in config files, and proxy settings in config files.
can you run javaws with no args and get up the application manager ?
if yes - look at settings in the preference panel of appman.
if no - look at javaws.cfg manually (in your users home directory/.javaws)
make sure the path to javaws.cfg.jre.0.path="xxx" points to a working javaws executable.
make sure the proxy settings: javaws.cfg.proxy.host and port are ok,

¿Does exist any tablet which runs java web start?

I want to buy a tablet pc, for example, Samsung Galaxy, Ipad... or similar, for me it's not important the brand.
¿do you know if exists any tablet which can run a java web start application?
My application is compiled with jdk 1.4 and starts by a simple .jnlp web file.

799037 wrote:
Thanks friend.
Then, ¿does anybody know a particular model of tablet pc that runs JVM (and therefore JWS)?Read what I say: you need a tablet which runs a normal Windows or Linux OS. You don't run the JVM, the JVM has implementations for specific operating systems. So that is your criteria: it must be able to run such an OS. Once you have that, you can install the Java runtime on it.
Generally that will be a laptop/netbook which can be transformed into a tablet by turning the screen. Check your favorite computer web shop for possibilities, there are a few. Not really a Java question anymore either.

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?

Java Web Start and DeployDirector: What's the difference?

I am the product manager for DeployDirector at Sitraka (now part of Quest Software). I'm NOT in sales; I'd simply like to provide you with some information.
From talking with DeployDirector users and evaluators, and from my own discussions with the folks at Sun, I have discovered that there is great deal of confusion about the difference between Java Web Start and DeployDirector. I'd like to clarify this by periodically posting some information about the two.
Though the products seem similar in concept, they are designed for different purposes. They both deploy, auto-update and manage the JRE for client-side Java applications, but beyond that, they are quite different.
Java Web Start is ideally designed for applications deployed over the Internet, where application-provider trust is an issue. Why? The security sandbox guarantees that application can do no harm. (There's some good information about Java Web Start and sandbox apps on ScheduleWorld at http://www.scheduleworld.com/itsYourLife.html) Web Start's architecture simply consists of a client piece that interprets a JNLP file. Because of the sandbox and its simplicity, I believe JWS is best used for independent software vendors, independent developers, etc.
Because DeployDirector is ideally designed for internal enterprise applications, it does not enforce the security sandbox. Trust is not an issue here, because internal users typically trust their internal IT group. DeployDirector's architecture consists of both a client and a server piece, which allows us to support more complex deployment and update scenarios (e.g., scheduled and optional updates) and applications management capabilities like rollback, reporting, exception monitoring, authentication/authorization out of the box. All of this is configured through the DeployDirector administration console.
In some situations, DeployDirector may be unnecessary overhead. In other situations, Java Web Start simply does not provide enough capability and building in this into Web Start can be difficult.
If you'd like more information, we have whitepapers and case studies (including one specifically about DeployDirector and JWS) available on our website at http://www.sitraka.com/software/deploydirector/
If you'd like to discuss some of these differences, or if you have questions about DeployDirector, feel free to email me directly. (Or post here, of course.)
Thanks,
Sonal Champsee

Hi Gerald,
Given what I know about your emnity towards DeployDirector (which is clearly illustrated in this thread: http://forum.java.sun.com/thread.jsp?thread=348061&forum=38&message=1446155 that was evidently a response to this article: http://www.javaworld.com/javaworld/jw-11-2002/jw-1122-autoupdate.html) I'm going to take a (pardon the expression) "don't feed the trolls" approach here.
I'm simply re-iterate that JNLP, and its implementations such as Web Start and OpenJNLP, are designed for a very different set of users that DeployDirector. The differences in functionality between the two products reflect that.
The enterprise has different requirements in a deployment mechanism for its internal, critical applications than software vendors and independant developers. DeployDirector addresses the requirements of the enterprise. Frankly, most of our recent customers only chose to buy the product after initially rejecting it and (unsucessfully) attempting to use JNLP and Web Start. Sometimes people only learn the hard way: different users have different requirements which are suited to different tools or technologies.
