3D applet deployment -- download extension

Hi, I need to deploy an applet using Java3D package. Trying to avoid the installation hassle (on the client side), I want to put the three packages available on the server (j3dcore.jar, j3dutils.jar, vecmath.jar), and then add the class path of these jar files in the manifest of the applet jar file. It's not working. now I start to wonder if such an approach is feasible or not. Can anyone give me some suggestions? Thanks a lot. (By the way, I uploaded my files on geocities (the yahoo free webspace) -- guess this does not make a difference, right?

Maybe you can try Java WebStart.

Sorry. But I was not quite sure which forum would be the most appropriate one.

Problem with download extension.

Hi,
I've tried to run the java tutorial download extension's example but without success.
I've compiled the two java files and put the class files into their respective jar file.
- The two jar files are in the same directory (AreaApplet.jar and RectangleArea.jar).
- The AreaApplet.jar's manifest is :
Manifest-Version: 1.0
Created-By: 1.3.1_01 (Sun Microsystems Inc.)
Class-Path: RectangleArea.jar
- The RectangleArea.jar's manifest is :
Manifest-Version: 1.0
Created-By: 1.3.1_01 (Sun Microsystems Inc.)
- The applet tag in the html file is :
<APPLET NAME=test
     CODE=AreaApplet.class
     ARCHIVE=AreaApplet.jar
     WIDTH=100 HEIGHT=100>
</APPLET>
All seems to be good but I have a ClassNotFoundException with the RectangleArea class.
Please, does anyone see what's wrong ?

Hi,
I can give you the steps I follow.
In an empty directory (all the files are in the same) :
- I put the two classes in the files : RectangleArea.java and AreaApplet.java
- I compile the two classes with this command line :
c:\jdk1.3.1_01\bin\javac AreaApplet.java RectangleArea.java
- I make the jar files with these command lines :
c:\jdk1.3.1_01\bin\jar cf RectangleArea.jar RectangleArea.class
c:\jdk1.3.1_01\bin\jar cmf manifest.txt AreaApplet.jar AreaApplet.class
manifext.txt :
Class-Path: RectangleArea.jar <Enter>
- I make a basic html file with this applet tag :
<applet name=test code=AreaApplet.class archive=AreaApplet.jar width=200 height=100>
</applet>
- I delete these files : RectangleArea.class and AreaApplet.class
- I run my html file and I have : ClassNotFoundException : RectangleArea
But it runs correctly with the applet viewer :
c:\jdk1.3.1_01\bin\java -verbose sun.applet.AppletViewer test.html
Is it possible that a wrong system CLASSPATH can cause this error ?
Thank you for your help.

Firefox 24.0 does not update any YouTube page for the download extensions. Video aivalable for download is the 1th opened in the tab and not the video playing.

On YouTube, when more than one video have been played, staying on the same page, videos aivalable for download, by any Firefox Download Extension as Downloader Helper, Flash Video Downloader or 1 Click Video Download, are the format options for the first video opened in the tab, and not format options for the video actually playing.
I have tried resetting Firefox ( Firefox menu : ? \ Troubleshooting Information \ Reset Firefox), and reinstall Videos Downloaders (without Adblock Plus that I normally use), it did not solve the problem.
Temporary Solution :
Refreshing the http://www.youtube.com/... page ( by hitting the round arrow at the right of the adress bar ) allows me to update the download features but it is annoying as it restarts the playback every time I decide to download a video ( so is it having to remember to refresh the page ).
I am surprised it seems no one have experience and solved this problem yet.

Problem in deploying Java Extension to ORacle SQL Developer

Hi all,
I have developed a simple Java extension using Oracle Jdeveloper. This extension creates a preference in Tools->Preferences.
I have deployed it on Jdeveloper and it works fine. But when I deploy it on Oracle SQL Developer its functionality does not work
I am using JDeveloper 11.1.1.4
and Oracle SQL Developer 3.2.20.09 (Latest Version).

Hello,
You are giving few informations. Is the extension listed in the extensions tab in the 'About' tab? Are you able to deploy any extension to SQLD?

Safari doesn't download extensions- When I click on the install button it says "This developer's server appears to be busy. Please try again later."

I`ve restarted my macbook, checked the wifi (webpages still load), and downloaded the extensions from the developer`s websites. When I download the extensions this way they supposedly install but yet I've yet to see them actually work. (Ultimate Status Bar doesn't appear in links, News Ticker doesn't show news, etc.) I know I probably installed too many, too fast. I uninstalled all my previous extensions and the problem still persists.
I've tried installing the same extensions on my iMac and they work perfectly. What can I do??
Thank You in advance...
Adrian

Can you install from the Safari Extensions Gallery instead > https://extensions.apple.com/
Downloading extensions from the internet instead of the Safari gallery may not be a safe thing to do anyway. I downloaded the file from here > http://ultimatestatusbar.com/ then a dialog asked if I wanted to download from the internet. I for one never download extensions except from the gallery.
I found it in the gallery > https://extensions.apple.com/
Try downloading from there instead. That will download the file to your Downloads folder. Double click the file to install.

DeployJava.js ,Applet Deployment errors?

Some great work has been done on applet deployment. ref: [Applet deployment toolkit |http://blogs.sun.com/thejavatutorials/entry/deployment_toolkit_101 ]
I've been trying to use this tool with considerable frustration. I'm serving internet applications on Godaddy.com and jar file usage is problematic during development with them. You have to wait for up to 24 hours to deploy .jar contents. What the fix? Use straight up classes to prove out an application. I know that I have users without java browser add ins, and I'd like to use the deployJava routine to keep things easy (for me!)
Problem is that the deployJava.js defaults are set up for JNLP and .jar files. For anybody stuck with "Exception: java.lang.ClassNotFoundException: ..." errors, with deployJava, and you are only using .classes and not .jar files, you should be aware of the following:
You have to specifically add the codebase_lookup parameter to the deployJava routine. [ reference: Codebase_lookup |http://java.sun.com/javase/6/docs/technotes/guides/plugin/developer_guide/special_attributes.html] This script assumes codebase_lookup = false. Thats not good for us xxx.class only folks.
suggested solution:
<script src="http://java.com/js/deployJava.js"></script>
<script> var attributes = { codebase:'classes',
code:'directory/cool_function.class',
width:1000, height:650 };
var parameters = {codebase_lookup:'true'}; <----- default behavior is 'false'
deployJava.runApplet(attributes, parameters, '1.6');
</script>
Info offered here in case anybody else gets stuck on the same errors as I.
thanks for reading. --Zip

I have something that could be improved in the deployJava.js.So don't tell us. Raise a bug report through [http://bugs.sun.com/bugdatabase/].
I'm sure this is something which could be done easily.In that case, make sure your bug report includes the changes to be made to the JS. Bug reports with code solutions will likely be given a higher priority than reports where the reporter reckons it will be easy for someone else to do the changes.

How to deploy customer extensions in EJB-Server?

Hello,
I would like to know, what is the best way to deploy customer extensions
to a J2EE application (which is deployed as an .ear file) .
I am using a configurable dynamic class loading to allow product
customization (usually implementations of interfaces).
I know some possible solutions, but...
1. solution: the customer provides its product extensions as a jar file
which is then located in the classpath of the J2EE server.
But I dislike this solution, beause it requires a server restart if the
customer extensions are redeployed and further on, depending on the
customer company's security restricition, no access to the J2EE server's
CLASSPATH might be granted.
2. solution: the customer opens the .ear file of our product, adds its
extension.jar to it and the extension.jar has to have a predefined name.
By that we can make sure, that the classloader finds this jar (because
it can be referenced in the classpath of the manifest.mf of the ejb.jar,
it will do no harm, if it does not exist).
What do you think about this?
Are there other possible solutions?
Best regards from sunny Black Forest, Germany,

Deploying Adobe Extension Manager and Toolkit for CreateJS

Has anyone tried deploying Adobe Extension Manager and/or Toolkit for CreateJS through Group Policy. Any tips for gettig it to work?

We haven't tried to deploy Extension Manager through Group Policy. Maybe you can consider Adobe Application Manager Enterprise Edition (AAMEE): http://www.adobe.com/devnet/creativesuite/enterprisedeployment.html .

Applet Size - Download times

Hi
this might be completely stupid questeion - but is there a way of checking how long it takes an applet to download without building it.
'I know that my applet has 2550 lines and need to increase this by approx 10-fold to approx 24073. Does this mean that the applet will take 10 times longer to download?
Is this very large for this kind of thing? The new lines are a lookup table - could i do this differently?
Aparantly we want to avoid linking to a database - but will do if it is the bast way -
Is there anywhere i can read up on this?
Many thanks

'I know that my applet has 2550 lines and need to
increase this by approx 10-fold to approx 24073. Does
this mean that the applet will take 10 times longer to
download?Depends on how you distribute it.
If you use a jar, then stuff gets compressed and it depends on your data's "repetiveness" how much this yields.
On the other hand, different people have different connection speeds and it is not easy to judge speed.
Depends on where your typicall users reside, and
how they are connected.

How can i download extension updates as files, to install on another computer?

Installed FF on my wife's work computer, in our gradeschool library. The network that she is connected to allows FF to be updated, but blocks extension updates. How can i download extensions as files, to a stick at home, to update her computer? Extensions used are AdBlock+, TabMix+, NoScript, ForecastFox, checkCompatability, and (since FF29) Classic Theme Restorer.
Both machines running Win7; FF28 at home, FF29 in the library.

hello kthompsn, you can right-click the '''+ add to firefox button''' button on addons.mozilla.org & select "save target as...".
<br>then you will end up with a .xpi file that you can put on a memory stick and install on the target pc by dragging the file into an open firefox window.

SOLVED Downloading extensions

Hey dev team,
I'm running JDeveloper 10.3.1.2 (ok, behind one version) and I'm trying to download the Extensions SDK. I'm using the Check for Updates... as specified but the server connection doesn't appear to be working. Is there another download location?
Sorry to bother you with a stupid server-related thread but I'm an oracle intern here on-campus and kind of want to get the software to do my work.

Check your Web proxy settings under tools->preferences in JDeveloper.
If this doesn't help, you can download extensions directly from here:

and here:

Need applet deployment help!

Hey everyone,
I'm having an issue understanding why my .jnlp file is seemingly being ignored. I'm trying to deploy an applet as follows:
<body bgcolor="Black">
<br><br><br><br><br>
<center>
<script src="http://www.java.com/js/deployJava.js"></script>
<script>
    var attributes = {code:'System.AppletShell', width:800, height:600};
    var parameters = {jnlp_href: 'NGEngine.jnlp'};
    deployJava.runApplet(attributes, parameters, '1.6');
</script>
</center>
</body>And my jnlp configuration file is as follows:
<?xml version="1.0" encoding="windows-1252"?>
<jnlp codebase="http://localhost/applet">
    <information>
      <title>Project Foundation</title>
      <vendor>Company</vendor>
      <homepage href="http://www.company.com"/>
      <icon href="EconomicCenter.jpg">
        <kind>splash</kind>
     <height>100</height>
     <height>200</height>
      </icon>
      <offline-allowed/>
      <shortcut online="true">
        <desktop/>
        <menu submenu="Company"/>
      </shortcut>
    </information>
    <resources>
      <java version="1.3+" initial-heap-size="128m" max-heap-size="512m"/>
      <jar href="NGEngine.jar"/>
      <extension name="jogl" href="http://download.java.net/media/jogl/builds/archive/jsr-231-webstart-current/jogl.jnlp"/>
    </resources>
<applet-desc main-class="System.AppletShell" name="Project Foundation" width="800" height="600">
</jnlp>The problem is that I can get the applet to run if I specify to the deployment SCRIPT, the following parameters: code, codebase, and archive. At that point, the applet runs but it can't find my my jogl extension. If I manually feed the .jnlp file to web start everything starts up fine. Also, I am hosting these files via apache, and the .jnlp mime type has been set up correctly afaik (mime.types).
So, why is it that the .jnlp file is seemingly being ignored?
Thanks ahead of time!

Thanks for the reply. Just a quick note, I'm both relatively new at coding in Java, and completely new at deploying anything in Java, so if any of these questions stem from a lack of research on my part, I apologize.
I've been using both these resources as primary references:
1* [http://java.sun.com/docs/books/tutorial/deployment/deploymentInDepth/runAppletFunction.html], and
2* [http://java.sun.com/javase/technologies/desktop/javawebstart/download-spec.html] (the 6.0.10 specification / 6.0.18?)
You stated that "An embedded applet JNLP should have no code base specified... ". However, according to 1*: "... if some deployment options have different values in the attribute name-value pairs and in the JNLP file ... leave the codebase attribute empty or specify an absolute URL. When the codebase attribute is left empty, it defaults to the directory containing the JNLP file." This is a bit confusing for me, because if I remove codebase attribute from the jnlp, which happens to be the "absolute path to the directory containing the JNLP file", I suddenly get an application error from the jdk web start tool: "BadFieldException[ The field <icon>href has an invalid value: EconomicCenter.jpg,EconomicCenter.jpg]". (The jdk tool starts everything perfectly fine if the codebase attribute is present.)
So I thought that specifying the document base might fix this issue, since my EconomicCenter.jpg resides in the same directory as document base, but that didn't seem to work.
Further, I have some confusion surrounding the point of the code attribute that deployJava.runApplet consumes. What is the difference between the code attribute, and the main-class attribute of the jnlp's applet-desc element?
If I try to launch the embedded applet/jnlp, from my browser, I get the error: "load: class System.AppletShell not found.", and the jnlp file is still seems to be ignored.
Also, I downloaded janela although it hasn't helped terribly much to get my feet off the ground yet, but here's the output in any case (with codebase removed from the jnlp open tag).

Error message when trying to download extensions in CC

I have downloaded two extensions now-- Font Finder and Flaticon-- neither of them are working. Both were downloaded in the mxp format, but the Extension Manager says they are invalid. Any ideas where to look to fix the problem?? Thanks in advance.

Please install Extension Manager CS6 (You may have installed it) from Adobe - Exchange : Download the Adobe Extension Manager , launch it, click "Tools"->"Convert MXP Extension To ZXP" menu item. After converting, you can install it with Extension Manager CC.

Problem in downloading extension

i have tried to download the archieve of 'java wireless extension' 10g of JDeveloper(file namely jwe.zip).
the working link for download was
http://otn.oracle.com/tech/wireless/tools/jwe/jwe.zip
even after several tries when i come with the downloaded product. it is always crupt...
why it is happening..............the archieve is by default crupt?????????
also i have tried it from update option inside the help of jdeveloper 9i version....it also says in the mid of download "archieve is corrupt contact administrator at oracle"
plz check and verify and also solve it
thanx

I just tried the link for the file you specified and it downloaded perfectly.
Can you check the file size you get is it 23.9M?
A problem I've seem with some browsers is that if the temp directory doesn't have enough space they cut the file that they download.
