Deploying SWT application with web start

Hi there,
I was trying out to deploy the IBM's sample SWT application, FileViewer, with web start, but ended with the following exception which I couldn't figure out how this happened.

I am now using JDK5.0. Even when I was trying out the JDK's sample Webpad, I got "Servlet JnlpDownloadServlet is not available" . Can anyone advise please?

Hi Jim,
Try to replace,
<jnlp spec="1.0+" codebase="http://localhost:8080/fileviewer" href="index.jnlp">
with
<jnlp spec="1.0+" codebase="$$codebase" href="index.jnlp">
But i was using JNlpdownload servlet to do the task

Deploying APEX application with web host

Hi guys,
Whats the process of deploying APEX application with a webHost?
We got a good deal from a web host with dedicated database, it still being processed.
Currently we have a domain name hosted elsewhere (non APEX host) . What I am planning to do is, create a subdomain with our existing web host and point it to the IP address of the DB machine the apex host will give us.
So I am guessing the process will involve:
1) getting the IP address of the database machine
2) configure the my existing web hosting setup to create a sub-domain and make it point to the IP address (for example 174.184.223.441)
Would I need Port number of the machine running Oracle DB with APEX and the local IP address (the one starts with 10.0.0.xxx) etc?
Would be grateful if someone can share what you did given you already have a domain hosted and need to create a subdomain to make it point to another APEX host.

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

Using Comm API with Web Start

I am trying to use Sun's Comm API with Web Start so I can access COM1 from my application.
When the application starts, I receive an exception for the CommPortIdentifier. When I run this
application as a standalone, it works fine. I have to assume that there is a problem with the
deployment of the Comm API.
I have include the win32com.dll in a jar file and defined it in the nativelib tag in the jnlp file.
The comm.jar and the javax.comm.properties files are include in another jar. I am not sure
what is the proper way to deploy these files and cannot find any documentation on this.
Does anyone know the correct way to handle this?

should like like this

<jar href="application.jar"/>
<jar href="comm.jar" />
</resources>
<resources os="Windows">
<nativelib href="win32com.dll"/>

Then in the code in application.jar, call
System.loadLibrary("win32com");

How to Deploy J2ME applications with data in RMS?

Hello everyone,
I am designing a J2ME application, a simple "Who wants to be a millionaire game". It stores questions and answers from a rms datastore. I want to to how can I deploy this application with questions and answers in the recordstore. Each time I run the emulator, the data stored previously gets deleted. Is it possible to attach the rms recordstore along with the .jar or .jad files? If so how can I do it. Please help.
Thank you all in advance.

Thank you Sypress.. When I install it the code works fine. But I wanted to include data with the application. I think I found a way way. I added the data in a text file and while starting the application I inserted data from the file into the recordstore.

Can't load Stylesheet while runing application on Web Start

I've got an error "WARNING: com.sun.javafx.css.StyleManager$2 run Resource "null" not found" while runing application on Web Start.
It works fine while running on local execution. I've already signed jar files. So, It shoud not have any problem with java security.
I kept css in the jar fie. The code below is used for loading css file.
String stylesheetName = "/theme/default.css";
scene.getStylesheets().add(stylesheetName);There was a guy who had the same problem with me but there was still no solution for this problem yet. Applet and css
Does anyone know how to fix it?

Hello User,
Your path is wrong. It can't be good if your css file is inside your jar. (This is not a javaFx problem)
If you pacaked your application like that:
myapp.jar
-----theme
---------default.css
You should try something like this:
scene.getStylesheets().add(getClass().getClassLoader().getResource("/theme/default.css").toString());Niculaiu

Software Center Application Uninstallation Button Greyed Out and Deploying an Application with Uninstall switch Fails

Hi,
I tried everything I could find on the internet but no luck so far. I can successfully deploy MS Visio 2013 to the clients. I also want to be able to uninstall it from the clients. On the client machine Uninstall button is greyed out. This deployment is
installed as "Available" and there is only one deployment type within that MS Visio 2013 Application.
I tried the following uninstall commands in my deployment:
setup.exe /uninstall
setup.exe /uninstall
VisPro
/config .\vispro.ww\uninstallvisio.xml
“\\SRVSCCM2012\Sources\MSApplications\MSVisioPro_2013_64Bit_ENG\setup.exe” /uninstall VisPro /config "\\SRVSCCM2012\Sources\MSApplications\MSVisioPro_2013_64Bit_ENG\vispro.ww\uninstallvisio.xml"
\\SRVSCCM2012\Sources\MSApplications\MSVisioPro_2013_64Bit_ENG\setup.exe /uninstall VisPro /config \\SRVSCCM2012\Sources\MSApplications\MSVisioPro_2013_64Bit_ENG\vispro.ww\uninstallvisio.xml
I checked Product ID from Setup.xml and I know it is correct. My uninstallvisio.xml' content is below:
<Configuration Product="VisPro">
<Display Level="basic" CompletionNotice="yes" SuppressModal="yes" AcceptEula="yes" />
<Setting Id="SETUP_REBOOT" Value="Never" />
</Configuration>
Last night, I downloaded and installed Cumulative Update 1 for SCCM 2012 R2 and I haven't tried the deployment after the update,yet. I will try it today but please let me know what else to check.
Yavuz Selim Atmaca

After I updated SCCM Server and test client pc with CU1 , I tried to deploy visio as Required. It installed successfully. Then I uninstalled visio by deploying the application with Uninstall Action.
After that I tried to deploy visio as "Available" to see if Software Center Uninstall button works. However visio deployment does not come to Software Center's Available Applications List. I check the status of the deployment under the Deployments monitoring
node and it says Success "Already Compliant". I dont know what it means. Does config manager thinks that visio already installed?
Yavuz Selim Atmaca
2 or 3 hours later that -Succes "Already Compliant"- status of the deployment under the Deployments monitoring node is vanished automatically and Software Center application list showed the new deployment. I installed it and uninstalled it succesfully.
So, you are right Solution is the CU1 but I am still wondering why my available deployment took so time to be visible in Software Center althought I didn't enter any schedule to be available.

Trying to use 1.4 beta 3 with Web Start

Hello,
I'm trying to use the JRE 1.4 beta 3 on Windows with
Web Start and it keeps giving me an error when trying
to get the JRE version. I looked at the Sun docs on
Web Start for using beta versions of the JRE and it states to put this in my .jnlp file, but it doesn't seem to work:
<j2se version="1.4-beta" href="http://java.sun.com/products/autodl/j2se" />
Has anyone got this to work?
Thanks,
Cory.

I am having trouble with this as well. I have also tried the java1.4* for the version field and the client machine still states that it can not find the right runtime. Is there anything else you added?
thanks

Deploying a Java CORBA application in Web Start

I am a novice to Java Web Start. I have a sample Client-Server application with CORBA as a middle ware. The front end (Client) is in Java and back end (Server) is in C++. The application is run and tested with jar and batch file. Now I want to deploy that application in Java Web Start and JNLP.
I have configured the same by creating a JNLP file and signed jars.
Now as all knows any CORBA application needs a domain file ( .cfg ) and some org.omg classes to communicate with the server by RPC.
I am stuck with how to specify these domain file name, path, CORBA classes etc in my JNLP. Not even that, I can't understand exactly what configuration will make the CORBA apps work properly in Java Web Start so that it can communicate with the server as well. All the Orbix jars's, IDL Stub jars are present and signed. I am giving my JNLP file as a reference. Actually I have tried adding these domain files and CORBA classes as parameters. But as usual it is not working and after running the JNLP the Java console suddenly gets disappeared.

The firewall is present and allowed to access apps. When I am running the jar of my application from batch file then everything is running fine. The CORBA Server is a remote RHEL5 (Enterprise Linux 5) machine whose 'IP' and 'Hostname' is specified in *"C:\WINDOWS\system32\drivers\etc\hosts"* file. Server is running fine and after starting the Client the Server side remote method is invoked. Data fetched properly and everything is working like a charm.
When running from batch (.bat) file using jar My applications folder hierarchy is something like this.
Test_CORBA_App
------+config ( contains resources file and domain file )
------+lib_6.3 ( contains all Jars)
------+log ( will contaiin the generated log files )
-------runCORBA_App.bat ( the batch file I am running )
As depicted above the folder hierarchy, my domain file resides in "config" folder. The contents of the batch file are as follows :
runCORBA_App.bat
C:\jdk1.6.0_14\bin\java -Xms64M -Xmx512M -Dorg.omg.CORBA.ORBClass=com.iona.corba.art.artimpl.ORBImpl -Dorg.omg.CORBA.ORBSingletonClass=com.iona.corba.art.artimpl.ORBSingleton -jar lib_6.3\UI_Fall_Test63.jar -ORBdomain_name VOIAMODOMAINNEW 1
pause
The following things are specified in the batch file :
1. JDK path : ( C:\jdk1.6.0_14\bin\java )
2. Java VM arguments for max and min memory : ( -Xms64M -Xmx512M )
3. ORB class name: ( -Dorg.omg.CORBA.ORBClass=com.iona.corba.art.artimpl.ORBImpl )
4. ORB singleton class name : ( -Dorg.omg.CORBA.ORBSingletonClass=com.iona.corba.art.artimpl.ORBSingleton )
5. Jar file name to run : ( -jar lib_6.3\UI_Fall_Test63.jar )
6. Domain Name : ( -ORBdomain_name VOIAMODOMAINNEW )
7. Main function args : ( 1 )
I am trying to deploy this simple CORBA application in Java Web Start and JNLP. I kept this in my tomcat server web apps. The folder hierarchy is as follows :
tomcat
---+ bin
---+ conf
---+ ..
---+ ..
---+ ..
---_ webapps
----------+ host-manager
----------+ manager
----------+ ..
----------+ ..
----------_ Test_CORBA_App
-------------------+ config
-------------------+ lib_6.3
-------------------+ lib_6.3-Signed
-------------------+ log
--------------------CORBADemo.jnlp (.jnlp file)
--------------------index.html (.html file)
As you can see I maintained the same folder structure as it was when running from batch file. The jars I am using is signed and kept in lib_6.3-Signed folder.
My updated "CORBADemo.jnlp" is :
CORBADemo.jnlp

N.B
*1. I am running the Tomcat server in my own machine on port 8400 ( for sure, as I have deployed many .war files using this tomcat and all worked ). And using the URL below running the WebStart application.*
*2. I am running the JNLP from my own machine.*
*3. CORBA server is running on a remote RHEL 5 machine as I mentioned before also.*
URL : http://<My Machine IP>:8400/Test_CORBA_App/
As desired the Web Start application will make a call to the remote CORBA server on RHEL5 machine by initializing the ORB and resolving the CORBA NamingService. But exception is occurring as I posted in previous post i.e exception while resolving NamingService.
Now my query is whether the domain file ( DOMAIN.cfg ) is reading/ accessing properly from my machine while running the JNLP or not. Because I presume in Java Web Start special attention is required to read any .cfg file. If everything is fine why the error is occurring.
*@ EJP :* The ORB is desired to run and running on the CORBA Server remote macine i.e RHEL5 machine, because from batch file it is working fine.
Is it so that I need to run the Tomcat Web Server and CORBA Server from the same machine.

Making exe of application which work fine with Web start.

Hello guys,
i am working on on-line casino gaming.First thing i want to explain to you is about my current mechanism for downloading game.
I have used JNLP and web start to download all necessary files at client side and it works fine..At every time it checks new jars are there or not...
Now i want to make the exe of my java application which i can give to client on movable device like compact disk..so client can install the application from anywhere and play casino games..
Now I want to know how to make on-line application as executable (exe) and every time it checks for updates which is supported right now by jnlp file..
which thing i have to consider,which tool is easy to use,which mechanism can solve my query....
please help me out...
thank you in advance...

Hi
Chris RENAUD 768,
First of all the PDF files should be set to be read by the application you developed by default.
To set the default program:
Control panel \Programs \Default Programs \Associate a file or protocol with a program
In IE8 There used to be a key called HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\AttachmentExecute\{0002DF01-0000-0000-C000-000000000046} which stored the File Types that could either
Auto-Open or not. We can create a .bat file to automatically add a value here to achieve the goal.
The code is as following:
@ECHO OFF
reg query HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\AttachmentExecute\{0002DF01-0000-0000-C000-000000000046}
if "%ERRORLEVEL%" EQU "1" (
reg add "HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\AttachmentExecute\{0002DF01-0000-0000-C000-000000000046}" /f /v "PDF.File" /t REG_NONE
Note: Please Back up the registry before you modified the registry and delete the key {0002DF01-0000-0000-C000-000000000046} if it has existed in the registry before you ran the .bat file.
Best regards

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).

Deployment Issues using Java Web Start

I am attempting to deploy a Java application that works in JDeveloper. The app has a Database connection to a MSSQL 2000 Server which is loaded into the active Project Libraries as Other JBDC. When I deploy the app using Java Web Start I receive the following error: com.microsoft.jdbc.sqlserver.SqlServerDriver.
How to I need to configure my deployment so the JDBC works properly? Thanks in advance

I got it to work with the following settings:
1. edit ur ctbuild.xml file to have these settings:
<include name="BC4J/lib/msbase.jar"/>
<include name="BC4J/lib/mssqlserver.jar"/>
<include name="BC4J/lib/msutil.jar"/>
Then have the same jar files in localmt.jsp as
<jar href="adfjars/BC4J/lib/msbase.jar" />
<jar href="adfjars/BC4J/lib/mssqlserver.jar" />
<jar href="adfjars/BC4J/lib/msutil.jar" />
2. edit data-sources.xml file, if ur using external oc4j as
<data-source
class="com.evermind.sql.DriverManagerDataSource"
name="sqlserverDBDS"
location="jdbc/SQLServerCoreDS"
xa-location="jdbc/xa/SQLServerXADS"
ejb-location="jdbc/SQLServerDS"
connection-driver="com.microsoft.jdbc.sqlserver.SQLServerDriver"
username="scott"
password="PwdForScott"
url="xxxx"
inactivity-timeout="30"
/>
Thnks,
