Web Start &JDeveloper

Hello,
We're developing a web application which uses Java Web Start(JNLP). Is there any way to be able to install necessary security files (.java.policy,.keystore) to the clients' machine automatically? Or how can we force installing these files to run our applicaiton on the client's machine?
Thanks...

what necessary security files?
you build an app and then offer it to the client via JNLP
if you are asking if you can overwrite the security settings on the client, the answer is no, otherwise there wouldn't be any security FOR the client
am i missing something here?

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.

I did in this way.See the error message first.Try to understand the error and find out the extension name which is causing this problem.Go to tools-preferences-extensions and uncheck the respective extension and restart the jdeveloper.
If still this problem exists,go to <jdeveloper home>\jdev\extensions,close the jdeveloper app,delete the respective extension jar file and start jdeveloper.Thanks.

Err. in programs copiled with Jdev 9.0.3 and run with Java Web Start

Hi all,
when I build my programs with Oracle9j JDeveloper 9.0.3.988 and I use them with Java Web Start, programs do not run, while when compiled with Oracle9j JDeveloper 9.0.2.x it runs without problems.
The Java version used in both cases is 1.4.0.
Here's an example of the log from Java Web Start:

Does anybody know why this happens?
Thanks

Hi There.
We had the same problem with some of our code. We moved the definition of the class from a method out of the method. Like this:
public class{
class{
instead of doing this:
public class{
method() {
class{
This worked with the web start......

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"

XYlayout don't work with Java web start

I have created a simple application that display a 2 form, the second form
use oracle XYLayout. so far it works fine, than I put the application as
a Java web start, however I got an error message saying

Hi,

on the jnlp file I change to
<jar href="/om.jar" main="true" download="eager" />
<jar href="/jdev-rt.jar" main="false" download="eager" />
it's working fine now.

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

I am attempting to render the following .jnlp in MS IE:

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).
