Java WebStart and Mac OS X 10.8

I'm a bit afraid that Java WebStart applications are encountering a problem with the latest OS X release because of the Gatekeeper settings preventing Java WebStart applications from running. Is it really true that if an application is not signed with an apple developer id that it will no longer be allowed to start unless changes are made to the Gatekeeper settings?

http://docs.oracle.com/javase/7/docs/technotes/guides/jweb/mac-faq.html#gatekeeper
If this is the case then of course my question would be how can I additionally sign my webstart application built with maven on windows with a free apple developer id?

doing a test app where you replace the .png with a .jpg might be a good idea. If you do not have a "test app", you probably should for JWS. It does not have to do much.

Java webstart on Mac OS9.2

Hi I have a java webstart application that uploads files to my website, I now have 2 people that want to upload to my site that are running mac OS9.2.
They both seem to be having the same problem as that the java application just does not start. They both have Mac OS runtime for Java 2.2.5 installed
Can someone give me some clues as to what may be going wrong and where to look on a mac as I have never owned one and have no idea.
Thanks
Dean

http://www.versiontracker.com/dyn/moreinfo/macos/377&vid=381
From that site:
Mac OS Runtime for Java (MRJ) is Apple's implementation of the Java Virtual Machine (JVM), based on Sun Microsystems' Java 1.1.8 specificationAlso from that site, there is a version 2.2.6 (fixes some Oracle bug)
If you need anything other than 1.1.8, your only option is to ditch 9.2 (which is 5+ years old at this stage!) and get OS X

Java, Safari and Mac OS X

Hello,
I have a mac machine with both Safari and Firefox on it. I hit a web page that references an applet in a jar file. I set up Java preferences to always show the console. With Firefox, the minit I hit the page, the java console appears and I start seing the applet's output there.
With Safari, the page seems to idle (it shows the HTML ocntent) but there is not Java console, and no reaction when clicking buttons that invoke actioons against the applet.
I enabled Safari's developer windows (error log etc) and I just saw a few HTML warning about malformed <br/> tags. But these occur down the file, long after the object reference to the jar.
How do I go about diagnosing this problem?
Thanks.

The difference between Java webstart and Java Applet?

Hi all!
I'm preparing deploy my application. But I'm in two minds I should deploy My application follow Java Webstart model or Java Applet Model.
if i deploy application by using Java webstart then what will I get benefit? and otherwise?
Could you tell me some advices?
Thanks!

Applet runs in the context of a browser, Webstart requires a small piece of software to be installed on the client and then when you click on your link/icon webstart downloads your application from the server and runs as a Java application (not within a browser).

Different versions of Java webstart and Java Runtime Environment

Hi I am using a thin application client (swings application) which is downloaded as a jar file using Java Web Start. The earlier version of the application was deployed on the server and client using the version 1.5.0_09. Due to some performance measures we are changing the Client version of JRE to 1.6.0_03. Will this really help??
The approach we are following is bit confusing.
First we are launching the application in JRE 1.5.0_09 and creating a shortcut for that (WebStart shortcut). Later we are changing the Java Web Start version from 1.5.0_09 to 1.6.0_03 in the shortcut.
And of course also changing the JNLP j2se version tag to 1.6
The application we are launching using this shortcut but its throwing FailedDownloadException : Unable to Load Resource hxxp://ascdcf.....*.jnlp
The funny thing is when i launched the same shortcut using the 1.5.0_09 version i.e. only the WebStart version as 1.5.0_09 and the JRE on client as 1.6.0_03 the application starts.
I searched about this and came to know that webstart just deploys the application jar on the client in a browser independent form and then it is run on JRE. If thats the case (and if i am right) then Webstart version can be anything only the JRE version should be the latest as specified in the JNLP. Can anyone give me suggestions in this regard???
Also if this approach is correct where will we get more performance???
1. Is it running application on updated JRE Version i.e. 1.6.0_03
2. Or on updating Java Web Start i.e. 1.6.0_03 (curretnly which is not running)
Also the Java Web Start is a part of JRE then where does this lead to....???
I am just an amateur with great doubts.....kindly help......

Java WEBSTART on Mac OS X??

Has anyone played with Java Web Start on OS X - is it possible to get the source and recompile for OS X?
Any help would be appreciated.
Cor!

I am part of a team that have written an app for Mac OS10.1 to be launched via JWS. It is a Stockmarket Analysis App, and after a ~2MB download you can sign up for a free trial if you like. If is available at http://www.mytradingtool.com/stockman.jnlp - or if you would just like to read a little about it first, go to http://www.mytradingtools.com

Java WebStart and JacORB!

Hi All,
When running the application from command line using -Xbootclasspath
works fine, but when started from webstart, I am getting method not found exception. I was able to initialize the ORB properly(used ORBClass, and ORBSingleton options). Basically this is happening because of loading Sun's ORB instead of JacORB. Looked at this forum and applied setContextLoader() tip, but it didn't help.
I am using Java Web Start 1.4.2_02, and 1.4.2 Java.
Any Help is appreciated.
Thanks,
Sanjay.

Hi,
I am using jacorb with NO problems.
I load a signed jacorb.jar as an extension:
<jar href="lib/jacorb.jar" />
Then,
before calling orb.init, y load jacorb.properties as a resource from another .jar, and put it in a Properties object.
Properties prop = new Properties();
InputStream bis= null;
try {
bis = getFileJar(fileNamePropertiesJacorb);
prop.load(bis);
for (Enumeration e = prop.keys(); e.hasMoreElements(); ) {
     Object key = e.nextElement();
     String valor = prop.getProperty(key.toString());
     prop.put(key.toString(), valor);
Then, I initialize the ORB:
orb = org.omg.CORBA.ORB.init(args, prop);
Make sure these properties exists in your jacorb.properties file:
org.omg.CORBA.ORBClass=org.jacorb.orb.ORB and
org.omg.CORBA.ORBSingletonClass=org.jacorb.orb.ORBSingleton
Hope this helps.
Any doubt, ask me.

PI 7.1 ESR and Java Webstart very slow

Hi,
I have been using the PI ESR and IB on the snow leapord OS with Mozilla and Safari browsers. The java webstart seems to be very slow and working on the ESR objects is sometimes a pain as it takes long time to save , activate or change and sometimes I end up java heap space issues although we are running at a 2 gig heap size. Is it only me or is anyone else facing the same issue?
Is it time to go back to good old windows XP? or can this be fixed in Mac ...I love my Mac for other reasons though...:)

Hi,

HT5367 How can I tell if I have 64 bit Java installed on my mac? I have something like Minecraft on it and I want to install 64 bit java on my mac. PLEASE HELP! Thanks!

I just need a bit help on how to install 64 bit java, i searched on youtube for it but it came up with many that I don't know much about. Please recommend a video you guys trust or know about. thanks

You can use 3rd party software such as Carbon Copy Cloner or SuperDuper! to create a bootable clone on an external drive.
I use SuperDuper to create a clone. Yes, it's true the Recovery HD will need to be recreated after restoring a clone because neither of these softwares nor Time Machine backup that partition. It's really no big deal. You just reinstall Lion on top of itself after the restore and reapply any Software Updates including the 10.7.1 update. I've done this a few times with no issues.
The Lion Recovery Assistant app creates an external Recovery HD on like a USB thumb drive, but it creates this using the Recovery HD from your Lion install. If the Recovery HD is missing, the app will not create one for you.
EDITED:
Create your bootable clone on an external drive.
Create an external USB thumb drive with the Recovery HD using the Lion Recovery Assistant.
Swap out hard drives.
Boot from the USB Recovery HD thumb drive.
Use Disk Utilities to create a new partition (Macintosh HD), format it with the GUID partition table and Mac OS Extended (Journaled).
While in Disk Utilities, click your hard drive (not the new partition); then click the Restore button.
The Source of your restore is the external clone you created. The Destination is the newly created Macintosh HD partition.
Click the Restore button. The restore will take awhile depending on the size of the clone.
After the restore, boot your system and it should boot into Lion.
Reinstall Lion on top of itself to recreate the Recovery HD at the end of your Lion partition.
Reapply Software Updates including the 10.7.1 update (if you want it).
Hope this helps!

Where is the built in Java runtime and development environment in my MAC???

I keep reading that my macintosh (dual G5 with OSX 10.4.10) came with a fully configured and ready-to-use Java runtime and development environment, however I cannot find, nor do I know how to open it. Doe anyone know how to open this up? thanks so much!

Your JRE should already be configured so that when you double-click a self-executing jar or open a page with an Applet it will run.
Your compiler (javac) should be available through your sheel in your terminal application.
If none of this helps you (and it may well not) you may want to consider installing an IDE. Eclipse for example has a Mac OS version, I am sure there are others but I do not develop on Mac so I can't tell you about them.

Java and Mac OS X

Hello,
I have some problems in here while developing in Java using Netbeans 8 with JDK 8.5.
It happens that sometimes I face some weird behavior from Java, for example, I have a small window with a button when pressed call two more windows with 500x500 bounds, and the problem is that after few changes in the code these windows are not appearign correctly, they're totally without any bounds and the X and Y position in the screen are also wrong, appearing in the very corner of the left side of my screen. I am sure I did not touch the code from these.
I know Apple is trying to get rid of Java, so I wonder if it has something about it.
Thank you.

I have found Mac OS X to be very Java friendly for several reasons...
Out of the box, OS X has at a minimum version 1.3 of the JRE installed in addition to command line tools like javac, java, jar. Panther, 10.3, has 1.4 installed out of box. The JDK/JRE for the Mac is available via the Software Updates capability directly from Apple. That is, you obtain JRE upgrades in the same manner in which you obtain updates on the OS itself. And it's simple and painless to do.
I've used JEdit and BBEdit and also XCode. It sounds like XCode is available via download (good to know..). I installed the Xcode tools from a CD that came with the box CD set for my Panther (10.3) OS. With the Developer tools, I can use a program called Jar Bundler to create "*.app" files for my Java applications so that they run with a native look and feel on OS X - (I mean having an icon in the dock for the Java app, and the icon bounces up and down like the others when the app executes etc). This makes deployment easy. To the best of my knowledge, that kind of convenience does not exist on Windows. For windows OS I think it is necessary to obtain install and configure a separate third party application which creates the "exe" file for the java application.
All Browsers on Mac OS X are set up to use the JRE on the system. The drawback is that only Safari right now is capable of using version 1.4 of the JRE. All other browsers, Mozilla, IE 5.2, OmniWeb, etc will use version 1.3. The good news is that configuring for the plugin is done behind the scenes, automatically. No messing with Tools menu or creating symbolic links are necessary in order to have the browser find the jre.
