'Unable to Launch Application Error' - Java Web Start Running Under MS IIS.

I am attempting to render the following .jnlp in MS IE:
<?xml version="1.0" encoding="utf-8"?>

<jnlp
   codebase="http://localhost/LottoMadness/"
   href="LottoMadness.jnlp">

   <application-desc main-class="LottoMadness"/>
</jnlp>I've deployed the .jnlp, .gif, and .jar to MS IIS, running locally on my PC.
When I attempt to render the .jnlp in IE I obtain an 'Application Error' window stating 'Unable to Launch Application'. Clicking details gives me:

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.

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

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

"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

Deploying no java applications using Java Web Start

Hi,
I am new to java web start. Is it possible to distribute non java applications using java web start. I have an APP which can run on a desktop in standalone mode. The app has jusy HTML and Java script files. Is it possible to package this app and deploying using java web start? I am assuming If it is possible, I can make updates to the packaged app in the web servers and the updates will be downloaded next time the app is used provided configurations are correct?
thx

The app has jusy HTML and Java script files. Is it possible
to package this app and deploying using java web start? Not really. Resources for JWS need to be zipped,
while this HTML/JS app. will (I guess) not work from
inside the depths of a Jar (or Zip) archive.
Note that you can organise for those files to be
downloaded and expanded onto a known place
on the user's disk, by using an 'installer' element,
but..
...I am assuming If it is possible, I can make updates to the
packaged app in the web servers and the updates ..installers are only called once, and do not 'update'.

Unable to Launch Application error while starting IR

Dear friends
I am not a BASIS trained person, but wearing different caps because I am the only SAP engineer in our company and so learning on the job.
I have installed a new server that has (SAP ECC 6.0, EP and PI). This is an IDES version. The operating system is Windows Server 2003 R2 (64 Bit).
The menu System -> Status says that Software Component SAP_BASIS is Release 700.
The ECC part is working ok, since I have been using many custom and standard tables, Bapis etc.,
However, when I give transaction code "SXMB_IFR" to start PI, it opens the browser with a message at the top saying "You need to install Javau2122 WebStart 1.4.2. "
However, I have installed j2sdk1.4.2_17-x64 and entered the environment variable path "C:\j2sdk1.4.2_17-x64".
When I try to click on 'Integration Repository', it tries to start 'Java Web Start window and after a while fails with a message 'Unable to launch the application'.
I searched SDN and other blogs and tried suggestions like,
selecting Control Panel -> Java and removing temporary internet files. But this didn't help.
I have installed another server on a 32 bit system and that one doesn't have any issues. The main difference with this one is that it is a 64 bit server and has (ECC, EP and PI) installed on the same server.
I would appreciate any feedback or suggestions.
Thanks
Ram

Dear Ram
install JDK then
first set your environment variable like this... upto ur java bin folder.
JAVE_HOME C:\Program Files\Java\jre6\bin
then run your java webstart . goto preferences and there make proxy as none
now start IR again.. it will start.. if it fails again then take 1-2 more trial to start . It will open.
IN SAP XI/PI, java webstart is used to cache fat clients like IR and ID on local machines. So you need to make JWS proxy as NONE and then run IR or ID. with in 1-2 attemt it will cache all the required files.
then after wards it will run smoothly.
good luck

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).

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); }

Error while launching of the application thru java web start

I have java webstart 1.2. While opening one of the application, its showing me following error message,
"javaws.exe has generated error and will be closed by Windows. You will need to restart the program. An error log is being created."
After that application works fine(It does not close the application) and no log file is generated.
Can any one tell me what is the cause of this problem.
Regards,
Pravanjana

You shouldn't give up without studying the source of JMF.
JMFSecurityManager blocks opening the webcam when it recognizes that the application is executed as an applet. JMF - in fact JMFSecurityManager - cannot distinguish between an applet and a java webstart application because it only evaluates System.getSecurityManager().
If the application is deployed via webstart the System.SecutityManager is NOT null and so JMFSecurityManager makes problems.
So the easiest solution of this problem is to call System.setSecurityManager(null) before any static function of JMF is executed or any class of the Framework is instanciated - e.g in the main-function. Java webstart allows to execute the command if the .jnlp-file requests all-permissions.
Another possibility is to read the properties. Therefore jmutil.dll has to be deployed and in C:\WINDOWS\java\.jmfdir the first line must contain the path of jmf.properties. This should be an alternative but I haven't checked if it works.

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.
