Java Web Start IDE

Hi does any body know of I good IDE for Java Web Start apps. I would like one that could jus open and run the FileService Demo located on this page:
http://pscode.org/jws/api.html#fs
I'm having trouble with netbeans. package javax.jnlp does not exist

This link should help: (the jnlp stuff is not in the standard API )

Don't throw out your IDE because of a missing library

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 launch application with java web start (OILOM)

I'm connecting to a remote Oracle console from a server, using "oracle integrated lights out manager". I go to "Remote Control" and click on "Launch Console". After that, it download a JNLP file, called "jnlpgenerator-16". I open it with Java7 -web starter- update 5.

It happens the same under Windows 7 and Linux -using openJRE and icedtea as substitution of Java Web Start-.
I'm behind a proxy. In my browser -Chrome, IE and FF- putted the info of the proxy and I can browse. Aldo tried to put the info in the Java "Network Settings". It did not work -the launching of the console-.
I installed the last Java Web Start in Windows 7 -Java7 Update5-. I disabled my anti-virus and firewall. Always the same result.
Could you help me please. I don't have idea of what is going on.
Greetings.
PD: I tested from other machines of the company and it works. So, I guess is my laptop. I exported the oracle certificates from those machine and imported them into mine.

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 :-(

Unable to launch java web start

We have already devloped an application based on java web start. Most of the client machines, we try to install java web start and run the developed app, it works fine. For one of the clients machine, we have an issue with java web start itself, it does not startup and bring up the application manager. When you start java web start, it shows up the splash screen 'java web start 1.0.1' after some time, it vanishes and does not bring up the application manager. I have installed java web start 1.0.1_01 (build 04) installed on Windows 2000 Professional, by default that has installed JRE 1.3.1_04 also.
We verified the system, all the files being existing under c:\program files\java web start dir. And the JRE is also installed fine.
Couple of times we uninstalled, rebooted and installed.
Infact, we have even verified the file types for html, htm, which was set to msoffice, and we have changed to internet explorer. For jnlp file type it was already set to javaws.exe.
Can you please let me know what could be the problem.

Nagarjuna Rao Chakka

There's nothing to stop you installing 1.4 or even 1.4.2, it's the jnlp file that specifies which runtime version gets used to run your application - web start can be used to happily switch runtimes like this. You'll just need to have 1.4 and 1.3 installed on each machine. It's a good idea to upgrade the web start client as the old 1.0 version doesn't work at all well with Windows XP, it's structure of storing all the files in c:\program files works against the security restrictions built into XP.
Incidentally the config file you were looking for in under c:\program files\javaws\javaws.cfg, but this is different in later versions.
Your problem is most likely being caused by web start not being able to find the Java runtime version it was installed with, the client may well have installed a newer (or older) version of 1.3 which has broken the configuration.. another reason to upgrade is the old versions are very fragile in this respect; 1.4.2 can find installed runtimes far more dynamically. Fixing the config file above should get things working again, otherwise delete the .javaws directory in the user profile and re-start web start.
1.4.2 is the best at finding runtimes, but is marred by problems with the integration dialogs, locale always reported as en_US and some strange new behaviour with classloaders and malfunctioning auto installers.. jws 1.2 that comes with jre 1.4.1_x is far more reliable.

How can I open help file (HTML or .chm) from Java Web Start (new to JAVA)

Hi All,
Im trying to open the help file of my application.
When trying to access the help file from the GUI (pressing F1 for launching the help file), I'm geting the an error, something like:
"Can't show help URL: jar:file:C:\Documents and Settings\%USER%\Application Data\Sun\Java\Deployment\javaws\cache\http\Dlocalhost\P7001\DMwebstart\RMjar-name!/com/resources/helpFiles/MyHelpFile.html"
It seems that the file which is packed in a jar, was downloaded to the Java Web Start cache directory:
C:\Documents and Settings\%USER%\Application Data\Sun\Java\Deployment\javaws\cache\http\Dlocalhost\P7001\DMwebstart
The code which is activated when launching the help file is:
try
            ResourceBundle resourceBundle = DoubleResourceBundle.getBundle("Resource", "ResourceImpl");
            RuntimeUtil.launchFile(new File(resourceBundle.getString("help.file")));
        } catch (IOException e)
            // TODO Auto-generated catch block
            e.printStackTrace();
        }where the property "help.file" is in some property file in the resource bundle named "Resource", and looks like this :
help.file="com/trax/docs/help/global/MyHelpFile.html"
The function "RuntimeUtil.launchFile" knows how to launch any file in its default application, and indeed it does launches the html, when giving it an absolute path to the file on my PC, as "C:\Helpfiles\MyHelpFile.html" as such:
RuntimeUtil.launchFile("C:\Helpfiles\MyHelpFile.html");My question is :
The application is going to be deployed on a Customer PC. How can I access the html file from the code, with a relative path and not its absolute path on the customer pc, which I can't know?
I found these restrictions regarding web start:
(copied from "http://rachel.sourceforge.net/"):
*Rule 1: Java Archives only. No loose files.* All your resources have to be packaged in Java Archives (jar) if you want to have
them delivered to the user's machine and kept up-to-date automatically by Java Web Start.
*Rule 2: No file paths.* You can't use absolute or relative file paths to locate your
jars holding your resources (e.g. <code>jar:file:///c:/java/jws/.cache/resources.jar</code>).
Absolute file paths won't work because you never know where Java Web Start
will put your jar on the user's machine. Relative file paths won't work because Java Web Start
mangles the names of your jars (e.g. <code>venus.jar</code> becomes <code>RMvenus.jar</code>)
and every JNLP client implementation has the right to mangle your names
in a different way and you, therefore, can't predict the name with
which your jar will be rechristend and end up on the user's machine in
the application cache.Seems complex or impossible, to perform a simple task like opening a file.
Please advise (I'm new to Java and Web Start).
BTW, I'm working with IntelliJ IDEA 5.0.
Thanks,
Zedik.

Java Web Start no longer works after Update 4 (2)

There was another thread under this title for which a solution was found by correcting the designated "open with" app back to Java Web Start.
My problem however is the Java Web Start simply crashes every time i try to open it since the installation of Java Update 4. And I also have a couple of Java apps that also refuse to open since this update.
Any one have any ideas on how to fix this?

Hi,
Try this....
Go to Applcations>Utilities>Java utility and check to see whether it is denying requests to run the java applications. You will need to check the tabs and the options in it to identify the right one.
Also you can try this...
Remove the com.apple.launchservices.plist fron ~/Library/Preferences.
Regards and Good Luck

Java console doesn't launch when starting Java Web Start app from Firefox

Updated my Linux desktop from RHEL to Fedora 12 with resultant upgrade of Firefox to 3.5.9 and now when I launch our Java Web Start application, no Java console appears. The Java Control Panel still shows "Show Console" as set. My app uses Java 1.5 which I have installed on my desktop.
What do I do to properly configure my browser/desktop to support use of the Java console?
Please help, I need to debug our app!

..Please help, I need to debug our app!Cannot tell you the answer to your FF hassles (because I have no idea why you're seeing that behaviour(1)), but note that you might be able side-step FF by launching a JWS app. using the javaws tool directly from the command line or an Ant build file.
1) Though you might try rebooting the machine if any installation/configuration changes have occurred since last boot.
Also note that many problems with JWS apps. can be sorted be checking the JNLP using JaNeLA.

Problems to download with java web start

Hola to all.
I have the following problem. My application not discharge of the server when you exist a new version. The application runs off line but when exist a new version must download the last version, is the idea.
If I execute for first time the "launch.jnlp" file ( that is to say in the client equipment never execute the application ) java web start connects and download correctly the application and starts application, and creates the icon on the screen. But if the application already existed java web start executes the application that there is in the client and not download the new version of the server. I think, that problem its happen because the time waiting the response of the server is too long, and executes the local application. To resolve this, i execute the application on java control panel in online mode, and this work ok, because find a new version.
I leave you the launch.jnlp file.

To check this I used the a tcp monitor (Apache Axis).
The error message in Java Webstart is identical to the one discribed above.
In the tcp monitor I see the following :
HTTP/1.1 200 OK

Java Web Start and Firefox

Hello!
I want to use some java web start applications, which are started directly by clicking a link. My browser (firefox) doesn't know the java web start mime type (*.jnlp). Because of that I can only download the specific JNLP-File instead of executing this file to start the java app.
There is no jnlp mime type in the firefox section Edit-->Preferences --> Application and I can't add a new mime type because there is no funkction to did that job.
I have installed the jre and the jdk package. In firefox Tools --> Addons there is the plugin "Java Plug-in 1.6.0_19" listed.
Has anybody an idea, who to add the jnlp mime type in firefox?
Thanks for help!
Best regards,
Flasher

Maybe this can help you.

Java Web Start starting applet

Dear all,
I like to run heavy application as an applet and the best way is keep the jar containing the application in the client.
I am wondering whether I can use java web start or not to deploy in the client the jar with the applet and so the client doesn't need to reload the jar from server unless there's some changes in the server.
Can java web start also start the browser to start the application?
I don't see any example in the internet although in java web start documentation says it is possible.
Dani.

You don't want the 2 dukes... come Vietnam and I will invite you some beers... can you?
By the way... I know JWS is used to deploy applications.
Maybe my question was not clear... By using jnlp file you can tell jws what is the class to be launched once loaded the jar file, and so just using an URL with the path of the jnlp file in the server, the browser will reload the jar and then the application is launched automatically. What i am wondering is whether i can or not launch my applet just typing the URL where the jnlp file is and so use the same browser. Once the jar is loaded, the applet would be launched in the browser. I don't like every time the user has to use the application, first need to verify he has the latest jar file using one URL in the browser and then he has to type another URL to launch the applet...
Any ideas?

Screen Saver crashing my Java Web Start app

I've written a Java Web Start time tracker application that all employees run from the time they start work until they leave at the end of the day. The only problem is that there are a couple of people who from time to time find that the application has crashed when they unlock their Windows screen saver. The application window continues to show the screen saver image and the title bar says "Not Responding". In an attempt to get some clues, I had one person keep the java console running - but nothing new appears in the console.
I've personally tried crashing the app by using screen savers, but I cannot duplicate the problem. I've also tried letting my computer go into standby mode and I've let it hibernate. But every time, the application continues running as soon as I log back in.
Any ideas as to why the screen saver could trigger a problem like this for some users?

I've written a Java Web Start ... . The only problem is that there are a couple of people who from time to time find that the application has crashed when they unlock their Windows screen saver. >What screensaver(s)? Some important distinctions might be
- Windows standard savers (the savers supplied with the OS, if so, do they all use Open-GL or all use...?)
- Windows compatible, 3rd party savers.
- Saverbeans screensavers (Java based). E.G. <https://screensavers.dev.java.net/>

Java Web Start and Remote Scripting Incompatibility?

I recently installed the Java Web Start plugin to Internet Explorer, in order to run Sun's version of the Java Virtual Machine.
After the install, I am receiving errors when trying to run a web application that uses the Remote Scripting technology for client-server communication.
I think this might be related to the Java 2 security model, which requires all Java applets to be signed. The Remote Scripting client-side component seems to be unsigned, so that may be causing my problem.
Does anyone have a solution for this problem?
Any help is greatly appreciated.

Hi,
I had the same problem on a unix server!
The new build of IE on Windows 2003 from Microsoft that excludes the JVM (Java Virtual Machine), works fine with the JVM coming from Sun, except for the following.
We are experiencing problems, that if we are not logged in as Domain administrator, we get an Apache security prompt to log on, as soon as the RSProxy class is used. It seems that the Class is not picking up the current session, but tried to create another session, without a userid, and then prompts you for your login details.
We still cannot figure out, why it does not do it with the Domain Administrator account.
Can someone please have a look into this.
I think there is a simple configuration problem somewhere, that will allow seamless integration with Sun's JVM.
I could resolve it so far by loading the Microsoft JVM back into Win2k3 theough the Visual Studion 6 Cd's, but I don't like the idea of that!

Java Web Start and BC4J/OC4J

Hi all developers,
This is my first forum message, and I hope that there is someone that can help me.
Problem: A JClient using BC4J in a 3tier situation work perfectly well when run from within the IDE, however using the Web Start Wizard and deployed to the Application server and run from Java Web Start, it does not work.
Is there any HowTo or documentation on the right settings, roles, security, procedures, etc. with regard to Jclient, BC4J and Java WebStart?
Thanks
Craig

Ant build file which does the signing
Please make sure you make a backup of the existing bc4jlibs.ear before you use this build file.
