When we starting IR and ID, it will look for java web start platform? why?

hi praveen,
Java web start is platform to launch the java application.
All the file from the central server are copied to the local machine

How to setup Proxy for Java Web Start App ?

I'm having trouble getting Java Web Start to work.
at... http://java.sun.com/docs/books/tutorial/uiswing/14start/compile.html
It tell me...
To test whether your browser can launch an application using Java Web Start, click this link.
http://java.sun.com/docs/books/tutorialJWS/uiswing/14start/example-1dot4/HelloJWS.jnlp
I do that & see Java Web Start try to start but get message...
Java Web Start - Invalid Argument
Unable to launch specified application
An error occurred while launching/running the application.
Category: Invalid Argument error
Could not load file/URL specified: C:\Documents and Settings\Will\Local Settings\Temporary Internet Files\Content.IE5\OP8RSBCV\HelloJWS[1].jnlp
Then... http://java.sun.com/docs/books/tutorial/information/javawebstart.html tells me...
"This situation usually happens when your browser and your copy of Java Web Start have different proxy settings."
I click Start | Programs | Java Web Start | Java Web Start,,, then click File | Preferences | General
My choices are... Proxies: None User Browser _ Manual (User Browser grayed out)
If _ Manual checked then I get...
HTTP Proxy ______
HTTP Port _______
I'm running XP Pro via Wi Fi to a Linksys Wi Fi router to a cable modem... I'm also running Zone Alarm (tried turning it off but no luck)
I don't know how to set up the Proxy stuff... can any one please help me get this set up.
thanks - Will

OK, on my XP Pro system I went to...
Start IE -> Control Panel -> Internet Options -> Connections -> Lan Settings -> Proxy Settings
This is my 'Local Area network (LAN) Settings panel...
- user Proxy server for LAN is checked
- Address is blank
- Port is blank
So do I plug something in here... the ip address of my linksys wi-fi router and a port number or what?
My Java Web Start Preferences won't let me click 'Use Browser' only None or Manual
If I click Manual, I don't know what to plug into the HTTP Proxy and HTTP Port fields...
I tried the ip address of my router... thinking it may have a built in Proxy Server... and port 8080 as indicated by the Help page for the Java Web Start... but no luck.
I really appriceate any help on this...
thanks - Will

Java Update 4 -- "Safe" java-vm-args Arguments for Java Web Start?

Sun's Java documentation notes that JNLP files can request arbitrary arguments to the virtual machine using the java-vm-args argument. However, only arguments considered "safe" will be recognized. The JNLP spec doesn't list the safe arguments, since the list might change on a per-release basis.
Unfortunately I can't find a current list of safe arguments either on Apple's site or Sun's site. I am fairly sure that -Xss is no longer on the safe list, since it's not working any more, but it would be nice to have that confirmed.
Anyone have any ideas/pointers?

I'm pretty sure that list is not accurate for the Java Web Start released in Update 4 recently. I have an app which attempts to specify heap and stack sizes using java-vm-args="-Xmx1024m -Xms1024m -Xss8m"; when I use the Java console to display memory usage, it shows that the heap is 81MB (which is the default). If I use initial-heap-size="1024m" max-heap-size="1024m" in the same JNLP file, the heap size is set properly.
Unfortunately I don't think there's any way other than -Xss to set the stack size in a JNLP file, and I need to do that too.
It's also possible that I screwed something up which caused this problem, but I reproduced it on both my Mac Pro and my Macbook Pro.

Customize the "update message" for Java Web Start

For the default value (false) of silentInstallLicenseAcceptance in Java Web Start when an application's server side has changed, the user will be asked with a message box whether he/she wants to update his local application now or quit the application.
I would like to know if I can manipulate the message that Java Web Start should ask the user. I also would like to know if I can change the button from Yes/No to Upgrade Now and Upgrade Later.
Any API reference, idea, tutorial or sample code would be appreciated.

How to enable logging for Java Web Start on Java 6.

I'm trying to get logging working in Java Web Start from Java 6. In previous versions I was able to specify a log file in the Java Web Star control panel (or whatever it was called) , but I can't work out what to do in the Java 6 version of JWS. I've checked the docs and searched the forums here and on java.net but haven't been able to find anything.
Does anybody know how I can get this working?
Cheers
Stephen.

Sorry, I was in a hurry and didn't read your e-mail properly. Note: This is a thread in a public forum, not email.
If it were email, it would be a private conversation,
between you, me and whoever we add to the addess
list. ..and you would be paying consulatnacy fees for
my participation.
On the public forum, it can be seen by anybody, and
I don't send you a bill.
And on that note, when asking for free advice on
public forums, please read replies carefully (I
might ask the same of a consultancy client, but
since thay are paying by the email - it is really
their own choice).
..the problem is that I can't find where the log file
is being written. Do you know where it writes to?..
I understand it is specified in the logging.properties
in the lib of the JRE/JDK. E.G. several locations
for my current system..
C:/Program Files/Java/j2re1.5.0/lib/logging.properties
C:/Program Files/Java/j2sdk1.5.0/jre/lib/logging.properties
C:/Program Files/Java/j2re1.6.0/jre/lib/logging.properties

When drop .ps file into Acrobat Distiller message looking for network alias folder. Why?

Hi,
Anyone can help on this.
My system is OSX 10.6.4 on a MacBook Pro.
I have some window network Alias folders placed on my Desktop, created and placed there from my other office workers for easy excess to their hard disk. Like pick-up files and dropping files off without using emailing.
My problem is why? when ever I drop a .ps file into the Acrobat Distiller for converting .ps into .pdf file, a similar message asking for all the Alias folders, one at a time, will appear one after another (See attached). The .pdf file will only be converted and appear when all the Alias messages are click "OK" away.
In the past, I have done the .pdf conversion as mentioned above, no popping messages.
What must I do so that this kind of message do not appear again.
Obviously, if I delete all the Alias folders, the messages will not appear but I would rather like to know if I am missing something.
Help.
Thanks
Jack

It could be that Distiller thinks some fonts are on the server: Check your font settings. It could be a corrupt preference file. It could be a cache problem. You can empty your cache using Applejack or Onyx.

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

Hi.
I got a different problem. My Corba application works in JRE 1.6, but doesn't works in JRE 1.5.X. I got an unexpected error and my console shows:

Can you help me?

Mac OS 10.4.8 , Java Web Start and JRE version of 1.4.2 and 1.5.0 problem

Hello,
I've been searching internet and reading the problems related to Java Web Start and JNLP.
But no solution I read can solve what I faced.
I'm running Mac OS x 10.4.8 and Macintosh updates the Java in my machine so that it has Java version 1.4.2 and Java 1.5.0
The application I'm running needs to be running in JRE 1.4.2.
So I changed the Java Preferences so that the default Java setting is JRE 1.4.2. However, the JNLP application still running in Java 1.5.0
So I changed the MIME and make sure the JNLP is opened with Java Web start instead. The Java Web start is for version 1.4.2. I also change its preference so that the console is opened.
I tried to run the JNLP application once again. Java web start 1.4.2_09 starts and console open, but the Java Runtime is still showing Java 1.5.0
I adjust the JNLP file so that the version is only showing 1.4.2_09 (ignoring all other variables of version 1.4.1, 1.4.2, etc found in the original JNLP file). That didn't work either.
I search on methods on how to uninstall Java 1.5.0 in Mac - apple page told me that I can't do that unless I reinstall the whole OS.
I am henceforth declare that I am stuck now !!!! Heellllpp....

Are you up to date with the updates?
Update for Snow Leopard users:
Apple issued update 12 for Java for OS 10.6:
http://support.apple.com/kb/DL1573
Note: On systems that have not already installed Java for Mac OS X 10.6 update 9 or later, this update will configure web browsers to not automatically run Java applets. Java applets may be re-enabled by clicking the region labeled "Inactive plug-in" on a web page. If no applets have been run for an extended period of time, the Java web plug-in will deactivate.
If, after installing Java for OS X 2013-002 and the latest version of Java 7 from Oracle, you want to disable Java 7 and re-enable the Apple-provided Java SE 6 web plug-in and Web Start functionality, follow these steps:
http://support.apple.com/kb/HT5559?viewlocale=en_US
Further update:
Apple issued this Java related security update No. 13 on February 19:
http://support.apple.com/kb/HT5666
and Update No. 14 on March 4: http://support.apple.com/kb/DL1573
http://support.apple.com/kb/HT5677
The standard recommendation is for users to turn off Java except when they have to use it on known and trusted websites (like their bank). Javascript, which is unrelated despite the name, can be left on.

Custom classloader fails when using Java Web Start

Hope you can help me with a problem that is driving me nuts. I have implemented my own classloader to support plugins. This classloader works as follows:
1. The classloader is configured to access a plugin components jar file downloaded by jws.
2. The plugin components jar file contains other jar files which contains the actual plugin code to be loaded using my own classloader.
3. Upon initialization - my classloader extracts all jar files contained in the plugin components jar file into temporary files.
4. These temporary files are used by my classloader when defining plugin classes.
The classloader works fine when not using java web start. Then I launch the application using java web start with security policy in .jnlp file set to:
<security>
<all-permissions/>
</security>
After a while (it was able to load some of the classes) it fails with the following stack-trace:
Regards,
Terje

     at java.lang.ClassLoader.loadClassInternal(Unknown Source)
Does anyone have source code for implementing a simple class loader that can be used with Java Web Start (preferrably with all jar files to be used by the classloader wrapped into a jar file)

If you implement your own classloader, and then still run with a SecurityManager installed, then your ClossLoader is responsible for asigning the permissions to the code it loads.
You need your ClassLoader to extend SecureClassLoader, and implement the method :
SecureClassLoader.getPermissions(CodeSource cs) to return the PermissionCollection you want.

Java Web Start and Policy File

Hi,
I've a problem for Java Web Start (JWS) in working with Policy File.
I like to apply a policy file for a JWS application to fine tune the secuirty setting instead of granting permission in JWS.
For an applet environment, I can apply policy file like this:
appletviewer -J"-Djava.security.policy=all.policy" writeFile.html
However, in JWS environment, I try to apply in JNLP file as below but fail:

Could anyone please help on this!

There are two problems with what you are trying to do.
First, setting a property PROP=VALUE in the jnlp file does not mean that java will be launched -DPROP=VALUE, instead, javawebstart will call System.setProperty(PROP,VALUE) before your apps main() is called. The difference is, the property will not be set at the time the VM is initialized.
Second, the javaws security policy will not allow you to set arbitrary properties in an unsigned application. Only properties begining with "jnlp." or "javaws." (and possibly a few other specific props known to the native javaws code) can be set in an application unless <all-permissions> is specified and the app is signed.

Java Web Start and the Mac OS

I am new to the Mac OS and to Java Web Start. Using Java Web Start to launch a Java application on the Mac is discussed in several of the posts here. However, in the requirement section of the Overview for Java Web Start says
"Requirements
Desktop/Client requirements:
The client machine requires support for the Java Runtime Environment (JRE), version 1.3 or later. Java Web Start is available for Windows 98/NT/2000/ME/XP, the Solaris Operating Environment, and Linux."
As you can see, Mac OS is not mentioned. Yet Java Web Start exists on my Mac. Am I looking at the wrong documentation? The document is located at
http://java.sun.com/javase/6/docs/technotes/guides/javaws/developersguide/overview.html#jws
I don't know how to use Java Web Start . I don't even know where to look for help. If anyone would care to offer some help it would be greatly appreciated.

You are looking in the right place alright. The reason OSX is not mentioned in the document (or, by extend, any of the official sun documents) is that sun does not (may not?) provide an official java release on OSX. Java on OSX is implemented by Apple (and much to the dismay of both users and developers, they are not doing a very good job). Still, Apple's java usually fulfills the same specifications as the official sun java, so you can take any one of sun's documents on webstart or any other technology and it will usually work on the Mac. You just can't expect sun to assure that a technology will work on a platform they have no control over...

Certificate chain and Java Web Start

Hi,
I have an application as a JAR file with other JAR libraries. All these files are signed with a certificate that I have generated with my own CA (OpenSSL).
The trusted chain is this: rootCA.cer ->subCA1.cer ->jws.cer
jws.cer was generated with a Certificate Sign Request through the java KEYTOOL and then my CA has signed this request. After done this, I have put the jws.cer in the same keystore of the request but to do this I needed to put the rootCA.cer and subCA1.cer before in the keystore.
The keystore has now three certificates and the key pair of jws.cer. This certificate works good to sign the JAR files.
Is it all good?
When I call this application with Java Web Start a popup always appears and say "Certificate is valid, etc. etc.". All it's good but pop-up is shown anyway.
I have inserted the rootCA and subCA1 certificate in the client Java Web Start certificate store but the pop-up is always shown.
Why this?
Is It not enough to install the CA certificate (and then the SubCA certificate) in the JavaWS certificate (client) store to not have the pop-up visualization?
Thanks

no.
Having a validly signed certificate (even if ussing a root already in the jres trusted root ca store) only verifys who the code is comming from, it is still up to the user to determine if your are trustworthy (to grant trust based on that verified identity).
If you want to avoid seeing the certificate, you would need to import your certificate into the pre-approved certificate keystore. (that is , either into the User or System Trusted Certificates list) using the security tab on the Java Control Panel.

Java Web Start and Java Preferences

I am having trouble with Java Web Start and Java Preferences. I have tried reinstalling the update with the link http://www.apple.com/downloads/macosx/apple/application_updates/javaformacosx105 update6.html but to no avail. What else can be done ? Moreover the file /System/Library/Frameworks/JavaVM.framework/Versions/A/ seems to be in place, but Java Web Start wont open and Java Preferences can't access cache files. Any ideas about how to resolve this? I have been having issues with Java for a long time and have already done a clean Leopard reinstall and all the Combo updates. Java Web Start and Java Preferences worked correctly for a while after that but seem to have gone haywire again.

Java Web Start and JDK Logger

The JDK logger uses the logging.properties file in the JRE lib directory. However I would like to use my own logging.properties file as part of the application that uses Java Web Start. This config file will be part of the application jar file.
The usual way to specify the logging properties file is by using the -D parameter
-Djava.util.logging.config.file=logging.properties
How do I specify my own logging.properties file for Java Web Start? TIA.

I'm trying to track down a solution to that problem too. The reason is because of the strange way webstart is creating its own log. It attaches a class: com.sun.deploy.util.LoggerTraceListener which records console messages. The way it does this is by generating its own log messages at the FINE level. If you look in the javaws.log file which is inside of the webstart cache area, you can see the result of this. On a mac this is located at: ~/Libraries/Caches/java/log
So if the console handler is configured to printing out FINE level messages then an infinite recursion happens. If you change the console handler's level so it isn't printing FINE messages then it works. But I want to see my own FINE level messages, so that isn't a good solution for me.
I tried setting com.sun.deploy.level=INFO in the global logging.properties, so webstart's log messages would not show up in the console. However, it appears webstart resets this level on startup.
If you set that property using the resource loading you figured out above, it might work because that should happen after webstart does its own logging configuration.

Hi,
-To make IE associate with .jnlp is the same way you set in the explorer.
-but i'm using Netscape which is my prefer.. I just set it in....
EDIT -> Preferences -> Navigator -> Helper Application -> [New Types]
then Set MIME : "application/x-java-jnlp-file" and Application to Use : javaws.exe (Java Web Start)...
ummm this should make Netscape See JNLP file and launch it with JWS...
PS. Ummm... I have to say that i'm newbie.. sometime i know how to make it works but i don't know how to make it work properly. So if somethings wrong, DON'T hesitate to give an advice. I really want to know how to make those work properly.
Hope it works.
