Java web start error running Asset Editor or any jnlp page

When I try to launch Asset Editor or Import/Export or any of the jnlp pages that runs using Java Web Start, I get an error. Java 7 Web start starts but It throws “Could not connect to Server. Please check your Java Web Start and Browser proxy settings”.
I read conflicting opinions on the internet as to what version of JRE/JDK is needed and potentially some issues running Java Web start with Java 7. I have 64-bit java 1.7.0_45 JDK/JRE installed and no other version. I tried installing 32-bit 1.7.0_45 as well. I have tried to run it from 32-bit as well as 64-bit browser also. All situations provide the same error.
However, when I install JRockit, it seems to work fine. But we cannot use jrockit. We have to use IBM JDK/JRE 7 eventually. Currently, the java web start does not work on Oracle Java as well as IBM JRE.
Any help is much appreciated.

I found a solution for this problem. We have to apply patch 17634436.

Just thought it will be useful for anyone encountering this problem.

Java Web Start Error in through codebase url with SSL

I have created one Java web-start plugin application in swing which is launched from PHP site at browser plugin.
All things were working fine, but when we implemented SSL in our site it stopped working. And when we try to start the application from browser it thorws error like:
Unable to launch Application.
In Java console it puts following log:

Hi,
I am facing the exact same issue when getting a big jar of more than 7 megs. It seems to occur in some special network configuration that I am not yet able to figure out. It is obviously linked to the fact that the jar is unpacked on the client side.
Anybody ran into this one and understood the root cause?Please, don't resurrect old threads, and don't use signatures with addresses. I'm locking this thread.

Java Web Start Error in Tiger

I just received a new MacBookPro and when I attempt to download/run a Java application I get the following error (worked with my older system):
An error occurred while launching/running the application.

Check your web server's access logs to see how many requests web start is sending for each jar. After you've loaded the application the first time, for each subsequent launch, if you've got everything configured right, you should only see requests for the JNLP file and maybe some gifs because web start should load everything else out of the cache (if you're using the version-based download protocol). Or if you're using the basic download protocol, then you might see requests for each jar file, but even in this case, if your web server is prepared to evaluate the last-updated attribute for each jar request and for jars that have not changed, respond with no actual payload and a header value of Not-Modified, then that should run almost as fast.
You might also want to consider changing the "check" attribute of the "update" element from "always" to "background" for a couple of reasons. It should allow your app to start sooner (but this means that you might have to launch once or twice after an update is applied to the web server before the update shows up on the workstation). Also, my impression is that "always" is broken and prevents web start from ever checking to see if your jnlp file has been updated if you launch your app from a web start shortcut - launching from a browser is less likely to have this problem, depending on how often your browser is configured to check for updated resources.

Java Web Start error message when trying to run vSphere1.2 compliance checker

It installed fine but a javaws usage message displayed when attempting to run. Seems like this might be some kind of Java environment problem on the Windows 7 Pro desktop. Not very familiar with Microsoft, any ideas and/or suggestion?.

Thanks for your suggestions, I will look into them.
One assumption I made is since the install completed without incident the program was able to locate any needed resources.
Another assumption is since I received an error message from javaws then itself was being located - just lacking something else it needed.
Ran javaws from command prompt, received same usage message. Apparently using 64 bit 1.7.0_13, didn't see a Java folder in the 32 bit Program Files so would that be the problen? That 32 bit Java version is needed to run this? Java Web State 10.13.3.20-fcs.
I'm the administrator of the system, so privilege is not an issue
In Properties/Shortcut, verified that the .jar file was pathed correctly
Target -> "C:\Program Files\Java\jre7\bin\javaws.exe" -jar "C:\Program Files (x86)\VMware\VMware Compliance Checker for vSphere\vmcc.jar"

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.

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......

Not getting application in Java Web Start

Hello Sir,
I wanted to run an application using Java Web Start. So, I created a jnlp file and i have mentioned the necessary jar files and the main class file. when I clicked on the jnlp file, the application is running in the Server using Java Web Start and its shortcuts are creates on the desktop and in the startmenu. I am able to run the application by clicking on the shortcut in the server. But I am unable to Download the application in the Java Web Start. It is not showing any Error Messages and the application is not running in the cleint machines.

"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

Can not launch swing application from Java Web Start 1.6.0_37

Problem with CORBA application deployed using Java Web Start 1_6_0.

Java Web Start fans and experts:
We have been using Java Web Start to deploy the client side of a CORBA-based application since the inception of Java Web Start ... including Java Web Start 1.0 right up through the present.
With Java Web Start 1_6_0, we see evidence that Web Start is "tinkering with" the IOR that CORBA uses to communicate. In all previous versions of Java Web Start, independent of the JRE which the application uses, the stringified IOR have been the same size regardless of whether the application is deployed locally or via Java Web Start. With Java Web Start 1_6_0, the stringified IOR is much longer than the "real" IOR (again, regardless of the JRE used by the application itself). To me this smells like a bug in Java Web Start 1_6_0. Has anyone else observed this behavior?
Here are some specifics .... I've run the same client application with various JREs both with and without Java Web Start as the deployment mechanism. The application was compiled and runs against servers that are running JDK 1_5_0_09.
Here is the summary of my results from a Linux box running various JREs, various versions of Java Web Start, and also running as a non-JWS deployed application. I've listed the length of the stringified IOR in each case.
JRE 1.5.0 non-JWS client: stringified IOR length = 344
JRE 1.6.0 non-JWS client: stringified IOR length = 344 ... this, I think, excludes the JRE as the cause of these problems.
Java WS 1.5.0, JRE 1.5.0 JWS client: stringified IOR length = 344
Java WS 1.5.0, JRE 1.6.0 JWS client: stringified IOR length = 344
Java WS 1.6.0, JRE 1.6.0 JWS client: stringified IOR length = 1568
Java WS 1.6.0, JRE 1.5.0 JWS cleint: stringified IOR length = 1568
In all cases, the stringified IOR length is determined by the service receiving the message and is always running JRE 1_5_9_09 and is
always the same 344 characters in length UNLESS it was deployed
using Java Web Start 1_6_0, in which case it in nearly 5 times as big!
To me, it sure looks as if there is a problem with Java Web Start 1_6_0 to be adding so much to the stringified IOR. Note: it's hard to tell how different the underlying IOR is in the JWS 1_6_0 case because, unlike most other ORBs, the Sun ORB doesn't have a tool to extract the IOR into a human readable structure. However, I can think of no good reason why the identical application deployed using Java Web Start 1_6_0 should have a stringified IOR length that is different than that of the same application deployed in non-JWS form or should differ from the behavior seen in all previous releases of Java Web Start.
Any clues or suggestions? Has anyone else observed this behavior?
Thanks,
John

Any help is appreciated. Thanks.

I got the solution for ClassNotFound issue. To avoid this error, one need to package EJB stubs on client side. Packaging just the EJB interfaces doesn't help.
EJB stubs can be generated using weblogic.appc utility. For more information about this utility please refer

Java Web Start doesn't start

I have installed Java 7 update 51 in Mac OS X 10.7.5. Yesterday Java Web Start starts well but today doesn't start. /Library/Application Support/Oracle/Java/javaws displays this error:
Bad Installation: JAVAWS_HOME not set.

Hi,
I found some stuff, but it didn't work for me. Maybe you can give it a try.
1. Deactivate Proxy
Add or edit javaws.cfg.proxy.setting=NONE in the javaws.cfg file.
2. Deactivate Splashscreen
Add option "-Xnosplash" in the Windows registry for the .JNLP ending, i.e. "C:\Program Files\Java Web Start\javaws.exe" "-Xnosplash" "%1"
3. Run with Java VM
I created a .BAT file:
SET JWS=C:/Programme/Java Web Start
java -cp "%JWS%/javaws.jar" "-Djnlpx.home=%JWS%" com.sun.javaws.Main %1
To run Java Web Start simply run the .BAT file. To run a specific application run the .BAT file with the complete URL of the .JNLP file.
If this works for you, please drop a note here! Thanks!
Bye

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.

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.

Java Web Start doesn't start (Windows XP)

Hi,
I've installed Java Web Start on a Windows XP machine. When I try to run an application or I try to open Java Web Start directly the "Java Web Start" splash screen appears for a few seconds and than disappears and nothing else happens.
I heard that other people using Windows XP have the same problem. Can anyone help?
Java Runtime is 1.4.0, but I also tried some other runtimes as well with the same result.
Thanks in advance

Hi,
I found some stuff, but it didn't work for me. Maybe you can give it a try.
1. Deactivate Proxy
Add or edit javaws.cfg.proxy.setting=NONE in the javaws.cfg file.
2. Deactivate Splashscreen
Add option "-Xnosplash" in the Windows registry for the .JNLP ending, i.e. "C:\Program Files\Java Web Start\javaws.exe" "-Xnosplash" "%1"
3. Run with Java VM
I created a .BAT file:
SET JWS=C:/Programme/Java Web Start
java -cp "%JWS%/javaws.jar" "-Djnlpx.home=%JWS%" com.sun.javaws.Main %1
To run Java Web Start simply run the .BAT file. To run a specific application run the .BAT file with the complete URL of the .JNLP file.
If this works for you, please drop a note here! Thanks!
Bye

Java Web Start (JNLP) getResource return null.

I have a Java Web Start Swing application and with the Java version 1.6.0_u27.
same code run from jdk1.1.8 to jdk 1.6, more then 10 customers it's work fine, java web start only run on jdk 1.4.0 and jdk 1.5.0.
just migrate one customer from Java version 1.5.0_u6 to 1.6.0_u27.
sometimes, the getResource will return null, when system return null, then system cannot get any other resource, always return null.
It only happen in Java web start environment, work fine in command line (java/javaw), and same as the WebStart loses resources post,
"Unfortunately this cannot be reproduced easily. Sometimes this happens after some minutes, sometimes the application can be used for days without problems.",
note. all of my resource files put in the same jar file, one resource file in that jar get fail, all files will be fail.
after I get the url, I will use new BufferedInputStream(url.openStream()); to retrieve data, never use the File object.
for example, get resource from "/path/a1.xml", "/path/a2.xml"....... 30 minutes pass, get same file "/path/a1.xml" will return null, then all resource will return null.
URL url = getClass().getResource(s);
if(url == null) {
System.out.println(getClass().getResourceAsStream(s)); // also null, log only
// if the url == null, the following retrieve will be null
url = Thread.currentThread().getContextClassLoader().getResource(s);
if(url == null){
System.out.println(Thread.currentThread().getContextClassLoader().getResourceAsStream(s)); // also null, log only
ClassLoader loader = getClass().getClassLoader();
if(loader == null){
loader = ClassLoader.getSystemClassLoader();
if(loader != null) {
System.out.println(loader.getResourceAsStream(s)); // also null, log only
url = loader.getResource(s);
if(url == null) {
System.out.println("URL resource still can not found!!" + s);

I ran into the same problem with JNLP and IE.
Here is the trick I am using to make IE think that it is dealing with "real" .jnlp file. This works on JBoss-3.2.1/Tomcat-4.1.24 bundle.
In web.xml:
<servlet>
<servlet-name>fakejnlp</servlet-name>
<description>jsp that generates JNLP on the fly</description>
<jsp-file>start.jsp</jsp-file>
</servlet>
<servlet-mapping>
<servlet-name>fakejnlp</servlet-name>
<url-pattern>/start.jnlp</url-pattern>
</servlet-mapping>
Now, when you request start.jnlp (perhaps, with HTTP parameters), you end up executing your start.jsp. IE is happy. One limitation, though: if you need to pass parameters, there should be no href attribute in <jnlp> element.
