Re: Web Start Bumper Sticker Contest

here is some.
1.) Web Start TODAY!
2.) got jnlp?
3.) Here is your app; Here's your app on Web Start got any questions?
4.) broadband + Web Start = great applications
5.) honk 3 times for JNLP
6.) FREE! Web Start FREE!

Looking for alternative to Web Start

Hello all,
After a couple years of using Java Web Start to deploy our educational software to schools, we're starting to realize that we need a new deployment strategy.
h4. Here's what we're looking for:
1. All files should be kept in OS-standard locations for applications, such as Program Files for Windows and Applications for Macs. Deployment of this program should be no harder for admins than for any other application. That means nothing in the User home folder.
2. Can be installed directly from a CD or USB stick
3. Can be easily updated as new versions are rolled out (i.e. can download the new jars from our servers).
Does anyone know anything off the shelf that works like this?
h4. Here are the problems with what we have now:
1. Web Start deploys jars (by default) into Users' home folders. This causes the following problems:
1a. Every user on the computer has to install the program individually.
1b. System administrators don't have any tools or patters for large-scale deployment of programs into user's home folders.
1c. Users may have limited space on their home folders.
1d. Users' home folders may be on networked drives, meaning that all the jars need to be fetched over the network every time they run.
1e. Users' home folders may be regularly cleaned.
2. Although Web Start's cache folder can be changed, users may not have write access to those locations, so Web Start will not function for those users if they need to download new jars. While this may be ok for our software alone, it will break any other Web Start application. Web Start cannot have different caches for different applications.
2b. Also, administrators don't have standard ways to deploy to random cache directories on computers.
3. There is no easy way to install Web Start applications from CDs. Jar files have to go into the right folders as if they were being downloaded from a server. We have a way of doing this by starting up a Jetty server, but it is not very robust.
...however, we still want the ease of Web Start's updating. We want to be able to push out new versions, which admins could update and deploy to their schools the way they do for all other applications, and we also want to support rapid-release cycles for our researchers and people working on the cutting edge of our software. Preferably this would need to involve some kind of jar-differencing, as users should only have to download the smallest subset necessary.
I'm sure we could write this ourselves, but I imagine we aren't the first people to have these kinds of requirements and problems with Web Start. Has anything been written that seems to approach what we want?
Thanks,
Sam

If you're willing to pay, you might wish to try Denova's JExpress. http://www.denova.com/
It creates proper installers and has autoupdate support. I've not tried it but it seems to be the off the shelf solution you're looking for.
You might wish to roll your own by using the open source netx implementation of the jnlp protocol. The basic idea is that you create an installation exe for Windows and package for the Mac wrapped around the netx application. It's a bit fiddly but it does work (I've done this myself). For the time you spend doing this though, you'd probably be better off with JExpress.

JNLP without web start...

Hi,
I would like to use JNLP as it I like the method of specifying an application's configuration, eg jars, properties and native libraries. It's more controlled and versionable than having to use a command line 3 metres long.
However, we use Marimba Castanet and I want to stick with that, so no need for Web Start. My question then is does the JNLP or another package have an API that will allow me to start a java application using a .jnlp file without going through web start?
Also I need my application to have unfettered securiry access without signing the jars, just as it does at the moment where the application is started from the command line.
Thanks, jamie

with that, so no need for Web Start. My question then
is does the JNLP or another package have an API that
will allow me to start a java application using a
.jnlp file without going through web start?Sun's Java Web Start is just one instance of a client that adheres to the JNLP specs.
There are others. One is
http://openjnlp.nanode.org
a commercial one is offered by Sitraka, if I remember right (deployment director?)
Also I need my application to have unfettered securiry access without signing the jars, just as it does at the moment where the application is started from the command line.What is bad about signing the jars and having the user to accept the certificate one time?
Any sane jnlp implementation will of course feature a similiar security model, or do you have such a trusted environment that you can execute anything?

Marc

JRE 1.6.0_04 and java web start

Hello
Version 1.6.0_04 now contains JAX-WS 2.1

How can i do ?
Edited by: Laurentapo on Jan 31, 2008 6:29 AM

I honestly do believe I have read somewhere recently (some blog? where?!) that 1.6.0_04 won't be made available there as Sun would issue security release next (this? Feb?) month and did not want to bump versions in 2 consecutive months.
At least that is what I understood. Now if only I could provide link to the source where I read that... , I am sorry, am old :)

ZipException When Web Start is Downloading JAR file

We are experiencing a problem when we try to download our Java Web Start app remotely from the server using HTTPS.
It works fine when using HTTP.
There are a couple of JAR files that need to downloaded.
But, when using HTTPS it will choke on random JAR files and will toss the
following exception:
JNLPException[category: Download Error : Exception: java.util.zip.ZipException: error in opening zip file : LaunchDesc: null ]

     at com.sun.javaws.Launcher.run(Unknown Source)
     at java.lang.Thread.run(Unknown Source)
Does anyone have any ideas of what we might be bumping into here?
Any ideas for a fix or workaround?
I've search the bug database and the one that is matches most closely
is 6194024 but that does not target HTTPS specifically.
Any help would greatly be appreciated.
Thanks,

Is there a wrapped exception ?
what are the versions of j2se and Java Web Start you are using ?

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).

Web Start beginner - Web Start front end to existing web app?

Hi all,
I'm new to Web Start, though have been hearing about it for some time. Even after reading the documentation, I have some basic questions about it.
Specifically, is it possible to invoke business methods via something like a Struts ActionServlet through a Web Start gui? That is, say my Web Start app and my existing web-based Struts app were on the same server, could I easily invoke the ActionServlet by passing in a URL with parameters? Thus giving me the ability to completely reuse my 'MC' of my Model-View-Controller app, and just replacing/adding another view ('V')?
Has anyone ever done this? If so, are there good examples?
Thanks in advance,
Mike

WebStart is a deployment mechanism for otherwise perfectly normal Java applications. WebStarted applications run on the client, not the server. WebStarted apps run in a protected environment (the Java sandbox), meaning they can't do potentially harmful things on the client machine such as reading and writing files or creating network connections to any server other than the one they were loaded from, unless you obtain special permissions from the user (the application needs to be signed for this to happen).
So there is nothing that specifically prevents you from using a WebStarted application as a front-end for a Struts webapp. If it makes sense to use a client-side application for that purpose is a question only you can answer.

Web Start and Web Application

I have a scenario as given below.
I have a Central Server hosting a web application(JSPs, jars) in Jetty 6.0.0. I have many branch servers having Jetty 6.0.0 installed and the web application deployed.
Now, I want to update the web application on all my branch servers whenever a modification is done on the Central server.
Can Web Start help me in such a scenario?
So far I understood that Web Start can be used to deployed / update only Client Applications.

Did you ever find a solution?

Very Urgent Unable to Launch Application using Web Start using JDK 1.4.2

Hi all
I am very serious issue i have ejb client swing application that uses
RMI to contact a session bean deployed in JBoss now i want the client app to be installed in the client machine using web start . Also i understand i require security permission to access network resources. so i have signed all the JAR files with same certificate created using self certificate avialiable in JDK by default also in the JNLP file in have included the following tag
<security>
<all-permissions/>
</security>
Now when I launch my application using Web start it gives an error that " Unsigned application is trying to access local resources"
I unable to understand what could be the problem . Please help me with the steps to be followed where in client should be able to RMI call to the server
Thanks in Advance
Naveen

You may have tried this already, but you might have to sign the jars via command line, outside any export process from your IDE.
$ jarsigner {filename}.jar {key from keystore}
I also had problems using webstart and RMI through an RCP

Java web start running on windows NT4 work station

I have installed java web start on a windows NT4 work station (service pack 6) with a directx v5. I successfuly launch the sun applications such as swing set 2, but I have some troubles concerning our software which used another look and feel than the default one. A system error is raised saying that the library ddraw.dll could not be loaded.
I have unistalled and re-installed directx v5 but the error is still raised.
Does any one can help me to solve this problem ?.
Thank you.

Hello Sim085
thanks for your reply.
Perhaps it would be easier for us to continue the programming with any kind of VisualStudio Produkt ;-), although we dont't had to think about OOP yet!
Because of our new Network-Technology (Terminal-Server) we have to discuss serveral possibilities.
I've read about JSP and ASP.NET, and I want to know if JSP or any kind of JAVA Program will run on a Terminal-Server.
Are there any special aspects I have to know when running JSP on a terminal server from Microsoft? Is it better to program applications in JAVA or in JSP? ...
Thanks

Java Web Start running JasperReports

The following is the exception that is thrown when trying to compile an .xml report template to a JasperReport object, from an app that has been deployed via the Java Web Start:
dori.jasper.engine.JRException: Errors were encountered when compiling report expressions class file:
C:\Program Files\mozilla.org\Mozilla\DailyReport.java:4: package dori.jasper.engine does not exist
import dori.jasper.engine.*;
* I have deployed the application properly via Java Web Start; however, when running the application it is not able to compile the xml file to a JasperReport object.
* The .java file is created properly; but the app does not seem to be able to find the dori.jasper.engine.*; library.
* I have signed and included the jasperreports-0.5.0.jar (and it's dependencies) with the app, and have put the path to all of it in the Class-Path of the manifest file.
* NOTE: Just FYI, I am able to run this without any problems under netbeans.

Dear Patrick,
Recently I have used iReports for generating report through java & deploy it through java web start.
I had taken all the measures you had mentioned in your previous replies. But I am not able to view the report. ( might be it is not compiliing)
I am using new version of jasperreports-0.5.3.jar
also through console it is running well.
Also it is not giving any errors. can u have any idea about this.
Might be it is silly mistake I have done.
My code for report generation is :
public class SReportA
     public SReportA()
     try
     JasperDesign jasperDesign = JasperManager.loadXmlDesign("/home/ora/iReport/RSENIORITYLIST-A.xml");
     dori.jasper.engine.design.JRBshCompiler theCompiler = new dori.jasper.engine.design.JRBshCompiler();
     JasperReport jasperReport = theCompiler.compileReport(jasperDesign);
     Map parameters = new HashMap();
     parameters.put("uname","admin");
     Connection con=null;
     try
          Class.forName("oracle.jdbc.driver.OracleDriver");
          con=DriverManager.getConnection("jdbc:oracle:thin:@158.144.71.219:1521:dbadp","acom","admin123");
     catch(Exception e)
          System.out.println("Exception in test.jsp "+ e);
     JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport,parameters,con);
     JasperManager.printReportToPdfFile(jasperPrint,"ReportA.pdf");
     JasperViewer.viewReport(jasperPrint,false);
     catch(Exception e){ System.out.println("There is exception here"+ e); }

Unable to run my application using java web start

i have created one application and use java web start to download the application. all the files are succesfully downloaded but when i try to run the application an expected error occur. this only happen in my machine but not in other machine i'm currently using
-jsdk1.4.2
-windows 2000 professional 5.00.2195 service pack 3
-pentium III 870 Mhz
-x86-based PC
-RAM 256 Mhz
Anyone knows why, plz help me with this puzzle

Please post the information from the Web Start "Exception" and "Wrapped Exception" tabs when the error occurs (I assume the error was in fact unexpected ;-)
A blind stab in the dark would be that you don't have write permission to the cache directory on the second machine. Also worth checking that the proxy settings on the second machine are the same as the first (if they are on the same network).

Unable to Launch Integration Builder: Java Web Start problem

Hi,
I am unable to launch the integration builder. I am using JDK 1.4.2_05. The java Web Start gives the following error:
Unsigned application requesting unrestricted access to system
Unsigned resource: http://<XIHostName>:50000/rep/repository/aii_util_rb.jar
I have tried deleting the Java web start cache, and even reinstalling the JDK.
Can someone suggest a workaround this problem ?
thanks,
Manish

The Java Web Start cannot accept unsigned jars. If the jars are signed, it will ask in a dialog box if it should allow unrestricted access to this jar.
In my case, I upgraded XI SP0 to SP4, which included updating the Adapter Core, Adapter Framework, and the XI TOOLS to SP4.
On launching the Web start, it seemed that the jars were not getting signed. JWS cannot allow unsigned jars to the client.
These jars are maintained in:
\usr\sap\<SID>\SYS\global\xi\directory_server\javaws\directory
I am having problems with my XI upgrade to SP4, and it is probably not signing the jars.
Do you know why this may be happening ...
thanks,
Manish

Unable to launch Integeration Builder - Java Web Start - Unexpected Error

Hi there,
I am not able to launch the Integeration builder. The ESR has no problem and is working fine though.
Here is the exception :- com.sap.aii.ibdir.gui.appl.ApplicationImpl
I have tried below options already :
1. Cleared the java cache under - javaws -logviewer
2. Go into administration and inside Directory --> Java Web Start Administration clicked "Restore archives and generate new sign."
Strange part is some of my colleagues here doesnt have any issue while opening the Integeration Builder. In fact I dont have any such issue in QA and PROD environment. The issue is only in DEV environment. Please advice.
Anshul

Hello,
Usually restoring the archives will help resolve the issue.
If the issue is occurring for just yourself maybe you could check that you are using the correct java version. e.g. for for 7. 1 java version 5
Also please refresh the Java Web Start:
If it's a Windows terminal, select Start - Run - javaws to launch Java Web Start and then clear the cache. File -> preferences ->
advanced -> clear folder button
If you have later versions of Java and doing the
Start -> Run doesn't give you anything, then select Start - Run and type Control and hit Enter. Double-click Java in the list
that displays to view the more up-to-date Java Control Panel. In the General tab, select Settings from the Temporary Internet Files section. Click Delete Files to clear the cache and then log into the Integration Builder again (download will be longer as jars will be cached locally again).
If the problem still remains I would advise to check that the latest patches have been applied for XI_TOOL, and also the other components MESSAGING SAP-XIAFC SAP_XIAF SAP_XIESR SAP_XIGUI

Sarah
