Java 1.6.0_3 Java web start causing repeated downloads of jar files

Has anyone else experienced the issue of repeated downloads of their jar files using 1.6.0 Update 3 ? This did not happen with previous versions. Looks like the way caching is done has changed with this update.
Thanks,
-- John

JDK 6 used "if-modified-since" GET requests, whereas 1.5.0 and earlier use HEAD requests for the timestamp. You might want to check what server is returning for these requests.

Java 7 Web start fails to download Java 1.6 version

Sorry for the almost exact duplication of a previous thread, but that was closed (Java 7 Web start fails to download Java 1.6 version
When launching an application requiring Java 1.6 with a Java 1.7 web start it fails when it tries to download 1.6 with the following message:
"Unable to download http://javadl-esd.sun.com/update/1.6.0/1.6.0_29-b11.xml for installation"
Problem only seems to occur on Windows 7 (64 bit), seems fine on Windows XP.
Bug has been raised with Oracle by poster Matt Taylor - http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7168311
Does anybody have any ideas?
Thanks,

0) Explain how exactly you launch JNLP when it does not work.We have a website with a link to a jnlp file. User clicks on the link the jnlp file downloads and installs.
"install the jnlp from the dos window" - do you mean run "javaws applicationURL"?Yes. But actually that only worked because we had already installed a Java 6 version.
When it does not work do you use Deployment Toolkit to embed link into web page?

How can I enable java applet plug-in and Web Start applications via terminal?

Since the last Java update to Snow Leopard, I have found that the system periodically disables the Java applet plug-in after a period of disuse. I know I can go to /Applications/Utilities/Java Preferences and just click to re-enable Java. But I want to write a script which will do this periodically for a couple hundred Mac users where I work.
My question is - how can I reenable the Java applet plug-in and web start applications via Terminal command? Is this possible? Is there a plist file that can be modified, etc.?
Bob Reed

It is my understanding that Apple's most recent Java update automatically disables Java after a certain period of time that it hasn't been used. We don't want users to have to keep re-enabling it. So we wanted to find a way to do this via script either run by a Casper JSS server or stored locally on each workstation.   With the guidance provided by Mark Jalbert above and some text from a script written by Rich Trouton, I was able to make a script (with some minor changes) and a launch agent to re-run the script upon login. So the preference is always enabled.
For your reference, the script content is:
#!/bin/sh
# DYNAMICALLY SET THE UUID FOR THE BYHOST FILE NAMING
if [[ `ioreg -rd1 -c IOPlatformExpertDevice | grep -i "UUID" | cut -c27-50` == "00000000-0000-1000-8000-" ]]; then
MAC_UUID=`ioreg -rd1 -c IOPlatformExpertDevice | grep -i "UUID" | cut -c51-62 | awk {'print tolower()'}`
elif [[ `ioreg -rd1 -c IOPlatformExpertDevice | grep -i "UUID" | cut -c27-50` != "00000000-0000-1000-8000-" ]]; then
MAC_UUID=`ioreg -rd1 -c IOPlatformExpertDevice | grep -i "UUID" | cut -c27-62`
fi

No option to Enable the Java applet plug-in and Web Start applications

How do I Enable the Java applet plug-in and Web Start applications
Their is no option under java preferences General Tab
The options i get their are
     Run appelts
          in their own proccess
          Within the browser process
          (Defaut most compatible)
Under the network tab im told
By default java applets and web start applications use network settings in the system network preferences. Only advanced users should modify these settings
Any ideas on why it is like this?

Mac OS 10.6.8
This happend once before when I was running 10.5.8 I fixed it but for the life of me i can't remember how i did it.

Error message at start-up Unable to access Jar file

I am a consumer, not a business...and not an IT professional. I am running Vista and have not installed any new software recently.
At every start-up, I get a pop-up titled Java Virtual Machine Launcher. The message says "Unable to access jar file". C:\users\user\.jnana.jnana.tsa.
Any idea how to fix this?
Thanks in advance.

ok i'm gonna make it easier on you.
i gess i found what is the problem but have no idea how to solve it.
when i obtained the .jar file i also obtained a README.txt file in which it is written the following phrase:
** If a library on the projects classpath also has a Class-Path element*
specified in the manifest,the content of the Class-Path element has to be on the projects runtime path.
I'M SORRY BUT I DID NOT UNDERSTAND WHAT IS MEANT BY: what is "the projects runtime path"?
the content of my manifest is:
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.7.1
Created-By: 10.0-b23 (Sun Microsystems Inc.)
Main-Class: hequalifies.ui.HeQualifies
Class-Path: lib/PlugIn
X-COMMENT: Main-Class will be added automatically by build
I'm having problem with lib/plugin.

Java Signing issues when loading web start app

Hey, not sure if this is the correct place for this - but couldn't think where else to put it...
I'm a bit stuck at the moment and i wondered if anyone could shed some light on my problem, and where I might go from here.
We've developed a EJB3 application that has a web start UI for users to start... The application is developed in Eclipse and compiled and deployed with ant build scripts... When we deploy the application from within Eclipse everything runs smoothly and users are able to start the web start app without any problems... However I've recently tried setting up a Continuous Integration server (Hudson) for us to test new deploys on and for this our build scripts need to be run outside of Eclipse...
This appears to run without a problem, however each time the system is deployed from here the web start application fails to start because web start cannot verify the signing in the client jar
Could not verify signing in resource: http://10.39.216.5:8080/mist2/lib/mist2-client.jarAs far as I can tell from the output of the build everything goes according to plan and there is little difference between the output if the build had been started in eclipse... The only big difference is that when building in Eclipse the build only packs up the compiled code, because Eclipse auto build the application, whereas in Hudson the code is clean built using the ant scripts (which are created by Eclipse)... and if I turn autobuild off eclipse and build the project from scratch using only the build scripts then the same problem arises...
I'm not really an expert on jar signing so I can't really guess at what might cause the verification to fail... any hints would be much appreciated. It feels like there is something that the Eclipse compiler does that is missing from the scripts but I can't think what this might be as the scripts are created in Eclipse
Thanks
Alex

Alex,
I believe your problem might be similar to one I had. According to one forum response (of course I can't find it now), if you have third-party JARs in your application (which in your case would be any eclipse jars), they might already be signed by their originators (as are eclipse jars), which may cause some really strange errors.
The solution for me was to package my third-party (that is, eclipse) jars into their own feature, separate from my application's feature. So, my main jnlp file has an extension to my application's feature jnlp, and that feature's jnlp file has an extension to yet another jnlp file containing the list of third-party (eclipse) jars. Of course, your jar list will probably be different than mine.
Here's all three files. Hope this helps!!

Java 7 Update 21 and Web Start Install Java Extension problem

Hi,
We've been running WebStart with Java 7 update 17 for several months. Late last month we updated to Java 7 update 21. Since this update, we're seeing 14 additional dialogs when the application is launched. Dialogs are Install Java Exception, do you want to install the following software? and then lists a jar file. I've verified that all JAR and JNLP files are signed with a trusted CA.
Has anyone else seen this? Is there away to suppress these additional dialogs?
Thanks,
Terry

I have just found that the use of uppercase/lowercase has changed in 7U21.
We have been running with the codebase notation like this: codebase="http://SERVER:port/folder/file.jnlp" since Java 1.4.2
In 7U21 I get a dialog pr. jar.
If I change to: codebase="http://server:port/folder/file.jnlp " the dialogs are not shown.

Java 1.6 won't download library jar files

I am developing 2 applets for use on an embedded web server, similar to what you would see when you connect to the web interface of a network router. I need charting functionality in both applets, so I'm using an open source Java charting library called JFreeChart. I have very limited disk space, so I want to keep the JFreeChart jar seperate from my applet jar, rather than zipping JFreeChart with each applet. So I've placed the files on the ebedded web server like this:
applet_1.html
applet_1.jar
applet_2.html
applet_2.jar
lib/JFreeChart.jar
When I open applet_1.html with Java 1.5_11 installed, the JFreeChart library jar downloads with no issues, but for some reason when I install Java 1.6_1 it just hangs. The java console shows the following:
network: Cache entry not found [url: http://10.0.1.200/lib/jfreechart-1.0.5.jar, version: null]
network: Connecting http://10.0.1.200/lib/jfreechart-1.0.5.jar with proxy=DIRECT
network: Cache entry not found [url: http://10.0.1.200/lib/jfreechart-1.0.5.jar, version: null]
network: Connecting http://10.0.1.200/jfreechart-1.0.5.jar with proxy=DIRECT
1.5_11 actually shows the same thing, except the jar downloads just fine.
In researching this problem I've found that there is apparently an "entirely new downloading engine" in Java 1.6, which is supposed to help with Web Start applications. That leads me to beleive that this is a bug with the new engine.
Should I submit a bug report? I have a packet sniffer program that I could use to capture the packets between the host PC and the web server, should I try to get this info to help diagnose the problem?

I am seeing similar entries with another applet.
I see three attempts on my Windows XP machine with JRE 1.6.0_10-rc2
one for /lib/QTJava.zip (which isn't there, nor should it need to be)
one for /lib/plugin.jar
and one for /lib/lib
Why on earth the applet or JRE is looking for stuff in those folders in beyond me, but it is adding 4 seconds to the applet load time while it goes off on a shopping spree trying to find things.
The same applet, when loaded on Windows Vista with JRE 1.6.0_07, the console doesn't show those errors at all.

How to authenticate a JWS Client download of jar files on a web server

Here is a history of how i tried to implement the auth system:
The resources(jar files) cannot be downloaded by any HTTP client from the server without some authentication method.
As JWS is not reliable when using cookies (only 1.5 supports them, but with problems when in JNLP file i specify j2se version=older that 1.5) , i implemented another mecanism that works like this:
1. 1.The template JNLP looks like this
<?xml version="1.0" encoding="utf-8"?>
<jnlp codebase="http://10.3.0.62/" href="mapped/#JWS_CODE#___#PLATFORM#___app2.2.jnlp">
    <information>
       bla bla
    </information>
    <security>
        <all-permissions/>
    </security>
    <resources>
        <j2se version="1.4"/>
        <jar href="http://10.3.0.62/mapped/gui.jar?jwsid=#JWS_CODE#" version="2.2"/>
        <jar href="http://10.3.0.62/mapped/data.jar?jwsid=#JWS_CODE#" version="2.2"/>
        <jar href="http://10.3.0.62/mapped/log4j.jar?jwsid=#JWS_CODE#"/>
    </resources>
    <application-desc main-class="com.bet.blues.gui.Application">
        <argument>-host</argument>
        <argument>ursus</argument>
        <argument>-port</argument>
        <argument>17771</argument>
    </application-desc>
</jnlp>2. All resources found in /mapped/ directory are mapped to JWSServlet
3. The users login to a site , clik on link , /mapped/app2.2.jnlp , the servlet checks if the session is active , gets the PLATFORM form browser request header , gets the JWSCODE for the logged user, replaces this in the template, and returns it to the client
4.Now after the 1st download the JNLP file is opened by JWS Client , that checks for latest version , requesting the JNLP file again
like this:
GET http://10.3.0.62/mapped/f12ks21092___windows___app2.2.jnlp5.Now the servlet sees the the request has a JNLP file name with an ID and PLATFORM, and serves the JNLP as before
6.The JWS Client will request for JAR Files
GET http://10.3.0.62/mapped/gui.jar?jwscode=f12ks21092?version-id=2.2Note: that i have forced JWSID parameter in the URL, that's why the query string contains 2 "?"
- forcing this is because the mapped/*.jar is redirected JnlpDownloadServlet that supports versions , diffs - i cannot use 'version' to put there the jswid param(e.g .../mapped/gui.jar version="fk12ks21092_2.2" because the JnlpDownloadServlet will not find this version , and if JWS Servlet will redirect to JnlpDownloadServlet with correct version param in request, the JWS Client will raise an exception because version responded is not right(JNLPDownloadServlet marks in response HTTP header the version of the jar so JWS CLient will chek it)
JWS Client expects version 'fk12ks21092_ver2.2'; to correct this i should modify the JnlpDownloadServlet and i shouldnt
THE PROBLEM :
on older versions than 1.5 JWS Client raises an exception because it wants to create a temp file named
" gui.jar?jwscode=f12ks21092" because it contains "?"
Only with 1.5 that seems to parse the jar name until it meets "?" char :(
Thats why i wanted to send an error to the client to upgrade to Java Web Start 1.5
Now, maybe u have a solution to this problem...
All i want is a solution to let JWS Client download jars only if the user is authenticated by some mecanism....and also support the versioning system.
Also:
Note that the jar names must preserve on the client JWS Cache dir ( i cannot use the same method to pass the JWSCODE when requesting the JARS as when requesting the JNLP).

You need to look into JAAS

Error while compiling Web Dynpro program due to missing JAR files

Hi Experts,
I am getting error message while compiling Web Dynpro program. The erring lines are as below:
          Message message = new MimeMessage(session);
          try {
               message.setFrom(new InternetAddress(fromMailId));
               message.addRecipient(
                    Message.RecipientType.TO,
                    new InternetAddress(toMailId));
               message.setSubject(mailSubject);
               message.setText(mailBody);
               message.setHeader("X-Mailer", "E-Mail");
               message.setSentDate(new Date());
               Transport.send(message);
The error messages are:

The method setSubject(String) is undefined for the type Message
The method setText(String) is undefined for the type Message
Type mismatch: cannot convert from MimeMessage to Message
Can you please help me in resolving the issue. It seems that some API is missing. I believe if some one can tell me the name of JAR file / API then I will be able to sort out the issue. I will add these JAR file in my program.
Thanks,
S

HI Stuart,
you are missing the jar files required for sending mail in java
Installing JavaMail
You will need the latest version of JavaMail (Version 1.2) available here:
http://java.sun.com/products/javamail/
Download and unzip the file, in the newly created top level JavaMail directory you will find a number of jar files,
these need adding to your classpath.
To do this in Eclipse, right click on your project in the tree view, select properties, select the libraries tab.
Now click the 'Add external jars' button, navigate to your JavaMail directory and click on the jars.
The tutorial also makes use of the Java Activation Framework, which is available here:
http://java.sun.com/products/javabeans/glasgow/jaf.html
Instalation of JAF is identical to JavaMail
activation.jar / mail.jar are 2 distinct names i remember rest you will get above
P.S: close the question to assist other users narrow the search and find solutions

Turning off jar cache causes classnotfound with signed jar files

Hi,
I have a problem with applet signed jars when the java cache is turned off.
With the cache turned off, I get a class not found for the first class it attempts to use from the signed jar file from an applet.
If I turn the jar caching on, all works perfectly with no other changes.
Anyone have any ideas? This is java 6u16.
Thanks

I think you should raise a bug report and seek Oracle's response.

Is web-inf/classes like a exploded jar file?

ie, can it make sense to have an ejb-jar.xml in the web-inf/classes directory of a war file?
Petstore has one!
Thanks
Martin

Unless I'm mistaken, yes, you could think of it this way.
In development, I usually compile things to WEB-INF/classes (and put .xml and .properties files there too) and when everything works, make a .jar of it.
Hope this helps.

Java 1.5.0.2 web start fix?

1. My reading of this 4 yerar old bug:
http://forums.java.net/jive/thread.jspa?threadID=315&tstart=0
lead me to belive that word smithing would be done to improve the scarry screen for the sofware publishers that are certified.
IT WAS NOT, SAME SCARY MSG. They could say something like:
"The publishers has been certified and they certify this sofware is safe. Please deploy Java application"
Look at how the Java Mobiel deploymnet team works.
It's like they want to prevent Java deployment becuase we users and developers are not educated enough about security.
Also, in the chat 2 weeks ago:
http://java.sun.com/developer/community/chat/JavaLive/2005/jl0301.html
the deploymnet team indicated improvments.
I asked several times: "How do you decide to weather to work on new feature or fix bugs" and the question was not answered. Deciding weather to work on bug fix or new feater is a critical tech lead decission.

Java 1.5 required for Web Start?

I just got our application to download and run through JWS, but it appears that WebStart is forcing all my clients to upgrade their JRE to 1.5. My JNLP clearly specifies 1.4.2+ as the required JRE, however. Is there somewhere other than the JNLP that the JRE version might be specified, or is there some kind of 1.5 requirement? Maybe it's just downloading the most recent version by default?
Thanks,
Dave

can u post your JNLP file

Recently i started getting repeated download of the same email even after reading it and often after moving it to trash.

i have outlook accounts. sometimes it works properly. sometime i get repeat download on one account, sometimes two or rarely three. this is new within the past few weeks. i run win8.1 up to date. thunderbird is up to date. i have made no configuration changes on my thunderbird settings. this is driving me crazy. i use norton internet security. i tried turning off email scanning. made no difference. it seems that the only sure way is to empty my trash, which i like to delay. sometimes i don't have to empty the trash...

i continue to have this problem and it is driving me nuts. i get the same messages repeated. somehow there is a failure in communication between TB and my outlook account. everything seems to be configured appropriately.
your suggestion to uninstall TB and do a new install seems wise. i don't want to lose any saved messages, etc. is there an easy way to backup the TB data?
