Java Applets in Safari

I'm trying to run a Java applet with safari, but everytime I go to the webpage all I get is a grey box with a picture of a coffee cup that has two arrows circling it. Nothing loads after that. Any idea how to fix this?

Hi ad1054,
Are you sure you have java 1.6 and if so, how did you get it? I believe the latest version available from apple is 1.5.0_06. Java 1.6 was only just released by Sun, and, if I'm not mistaken, only for PC and Linux. Apple may be waiting to force people to pay for Leopard to get Java 1.6. (Though you can get a beta version from developer.apple.com.) As Hawaiian_Starman mentioned above, you can check your java version.
That said, you don't have to worry about lower versions of Java because Java is backwards compatible. In fact, if you use Firefox (sorry, but I just checked it in Safari, and got a blank page so I guess Safari, like IE, doesn't support this) and go to "about:plugins" you will see something like
<pre>
Java Embedding Plugin 0.9.5g2
File name: MRJPlugin.plugin
Runs Java applets using the latest installed versions of Java. For more information: Java Embedding Plugin. Run version test: Test Your JVM.
MIME Type Description Suffixes Enabled
application/x-java-vm Embedded JVM xjv Yes
application/x-java-applet Embedded Java Applet xja Yes
application/x-java-applet;version=1.1 Embedded Java Applet xja11 Yes
application/x-java-applet;version=1.1.1 Embedded Java Applet xja111 Yes
application/x-java-applet;version=1.1.2 Embedded Java Applet xja112 Yes
application/x-java-applet;version=1.1.3 Embedded Java Applet xja113 Yes
application/x-java-applet;version=1.2 Embedded Java Applet xja12 Yes
application/x-java-applet;version=1.2.1 Embedded Java Applet xja121 Yes
application/x-java-applet;version=1.2.2 Embedded Java Applet xja122 Yes
application/x-java-applet;version=1.3 Embedded Java Applet xja13 Yes
application/x-java-applet;version=1.3.1 Embedded Java Applet xja131 Yes
application/x-java-applet;version=1.4 Embedded Java Applet xja14 Yes
application/x-java-applet;version=1.4.1 Embedded Java Applet xja141 Yes
application/x-java-applet;version=1.4.2 Embedded Java Applet xja142 Yes
application/x-java-applet;version=1.5 Embedded Java Applet xja15 Yes
</pre>
You can see from this list that all versions up to and including the currently installed one are supported. The only thing you have to fear is that the applet you are trying to use was compiled with Java 1.6 and is not itself backwards compatible. However, when I made a test applet of this type, I got a red X, and no coffee cup.
If you see the red X, and I think the coffee cup as well, you should be able to right-click (or ctrl-click) the icon. If so, this will give you a menu with "console" and "about" choices. "About" will give you the version of Java you have, and "console" is supposed to show you the errors that kept the applet from working. (However, with my Java 1.6 test, the console was empty.)
I hope this helps.

Issue with running Java applets on Safari 6.1

I conducted a system capability check on the course site I access (Defense Acquisition University) and one of the results indicated that I do not have the capability to run applets (requirements to run all courses). I verified my setings and I do have Java ver. 7 update 45 installed. I verified Safari's security preferences and confirmed that the "Enable Java Script" is checked. I tried configuring the website settings for Java plug-in but cannot figure out how to add url on the configured websites box. Is there any way to enable running applets in Safari? Any help is appreciated. Thanks in advance.

Please post a link to the page you're having trouble with (unless it requires a password.)

Cannot load java applets in Safari

I have several accounts on my machine. In one, the one I use most of the time, Safari will not load java applets. I have checked preferences and compared with those set on the other accounts. They are the same, including enabling javva and javascript. I have removed the Safari plist. I have repaired permissions. I have reset safari, cleared history and caches, used Cocktail to clear caches. I have rebooted.
I set up a new test account and it works fine.
What's going on, and how do I cure it?

I will try the pram reset, though I am not confident of it since this problem affects only one account.
On the new account business. I note that when I set up a new account, before I launch safari, there are no files in the Library related to Safari. They are created on the first launch. If I delete them all, then they are recreated on another launch. What if, in the affected user directory, I exported the bookmarks and/or dragged the bookmarks file to the desktop. Then deleted all evidence of safari from the account. I should now have, in effect, a virgin install of safari. Launching it would create all of the necessary files and directories. If safari works with java applets, or does not, I can simply move the bookmarks back in and be no worse off than I was in the beginning.
Any serious fault with that? I am working at home today so cannot do this until I am in the office on Monday.

Can't load Java applets in Safari

Ever since I installed Snow Leopard, Safari can't load Java applets. I get a blue Lego brick with a question mark, and a message telling me that Java was not found.
Firefox is unaffected, and I get the same error whether Safari is open in 32-bit or 64-bit mode. Programs written in Java, such as Vuze, are unaffected.

Create another admin user account log into it, and see if the problem persists. If not, the issue's within the original account, usually amongst preference (plist) files. If so, then it's system-wide and reinstalling the 10.6.2 COMBO update, repairing permissions, and restarting should do the trick.

Safari crashing when trying to accept a Java applet

Hi everyone,
I am pretty new to Mac environment but I have a very irritating problem.
Whenever I try to open a specific page (tried both v3 and v4 beta) which ask me to accept a java applet / certificate, Safari crashes and the only solution is to force quit the application.
I have all my applications up to date and using a current gen MacBook 2.4 GHz with 4GB ram.
However the same page opens perfectly in Firefox.
Best regards,

It is a datasite provider and you actually need a password to get in.

How relevant is Java Applet technology in 2006 for wide web deployment?

How relevant is Java Applet technology in 2006 for wide web deployment?
I'm developing a website which requires deployment Internationally to as many users as possible. Many people advise to stay away from Java applets, others say only use Java 1.1 (AWT limitation), some say use Flash, others say stay away from applets and plugins altogether.
Of course it depends on the content. I have interactive 3D content currently powered by Java 1.1 applet BUT I have been using Swing to introduce custom GUI functionality but which I know may limit compatibility. I'm torn by this whole debate and what impact it will have on the relevancy of my website.
How many users out there have browsers that will cope with my content?
Then there's the issue of all the various different browsers nowadays. I'm testing for IE and Netscape on Windows platform, but what about other browsers and OSes on other platforms? I notice that some websites have a page with tables to show users what browser is and is not compatible with their web content. How far must a web developer go to test all these things exhaustively?
Then there's the issue of a 16MB download for the latest Java plugin if a user's system is not up to date. Can all modern browsers handle Java even with the latest Java download?
Or should I just tell the user to get a compatible browser? Another 10-20MB download, depending.
Or how about Flash? That reportedly has a vast International deployment base, but do I need to pay for a Flash editor / IDE / compiler? So far I've been using freeware (HTML, Java, NetBeans, PHP, MySQL, PNG images) to achieve excellent results within my ludicrously limited budget. The Flash Player is only a 930KB download, and that is quite user friendly even if I must tell a user to get the latest version � only 2 minutes download on a 56K modem or about 15 seconds on DSL followed by a 2 second really easy install.
Look here to see where Java ranks against Flash and others :
http://www.macromedia.com/software/player_census/flashplayer/
I know Java. I use it for apps and now applets. I get it to communicate with my server's PHP and MySQL. It works well on my machine, but will my applets work for millions of users world wide with few technical problems? Looking through Java forums I see developers struggling with Java Applets in Safari on OSX but not on Windows. Then another has problems with Applets in IE on Windows but not on Netscape. Then one browser struggles with key events . . . it's like a mine field out there and I'm struggling for clear direction.
Microsoft's support for Java has been poor. If I depend on Java Applets now and for the next year, then will they still be supported 3 or 5 years from now? Or will I have to write off this investment in Java development effort and then switch to something else? Or switch to something else now?
Does Sun Microsystems somewhere reveal how ubiquitous their JVM deployment is?
Perhaps I'm totally misinformed, but Java Applets seem to be dying out. I'd really love to hear from other active web developers out there doing stuff for wide deployment to mass markets.

Since my zwebsite is already using Java 1.1 for 3D visualization I've decided to standardize on Java 1.1 to gain maximum browser compatibility. To add another technology like Flash at this point may just complicate matters, especially for me.
I'm now converting my Swing GUI to AWT. It wastes a lot of time, but the effort should be worth it in terms of the deployment success rate - in theory at least :-)
Just imagine if Java 1 had Swing . . . dream on!
In the deployment stats noted in my first post on this thread they state that Java has 86% world wide desktop deployment. Problem is that I bet that figure only relates to Java1. I wonder what pathetic percentage is true for Java2?
Regarding the use of Java for content rich dynamic content for world world wide web browser deployment . . . I'm rather disillusioned at this point. It seems for this application Java is stuck indefinitely at Java1 and the cool things they developed after that cannot be used effectively. Please note that I am ONLY referring to wide browser deployment. For stand-alone apps and targeted web deployment (where you can reasonably expect your user to upgrade his/her system for a good reason) Java is still very cool.
As for Java WebStart: I can see the uses for it, but it just does not fit into the browser application where the general public enter your web pages and see cool content inside the essential context of your webpage. This last point is vital for any serious web site. If the object of the site is to deploy a useful app to the user (like a forex trading front-end with GUI) then use Java WebStart by all means.
After this website, I'll invest in Flash. I'm sure Flash is not without its share of issues, but it has 97% deployment of nearly the latest versions and user download/upgrade is under 1MB. On top of that it does not seem to suffer from corporate relationship woes like those between Sun and Microsoft.
After all, Flash is labelled as a 'player' and not a Virtual Machine. Mass users out there want to play rather than know about complex and bulky IT stuff.

Citrix Access Gateway/ Java applet

I have just recently downloaded Maverick OS. But now i cannot get access to Citrix Access Gateway/Java applet through safari. However, when i use firefox i can. Why is this? I used to be able to get access through safari, until i downloaded Maverick.
Please help?

Is the Oracle Java plugin installed? If not, you need to install it.

Can I save as pdf when printing from a Java applet on a webpage in Safari?

I am trying to use a webpage that is running a Java applet. A dialog comes up that asks me, "Do you want to run this application?" The dialog also says, "This application will run with limited access that is intended to protect your computer and personal information." I select "Run". The applet generates an image I want to print. There is a "Print" button on the applet. I select "Print". A Security Warning dialog comes up that says, "The applet has requested access to the printer. Do you want to allow this action?" I select "OK". The Print dialog comes up. I choose the PDF button in the lower left corner. I choose "Save as PDF...". A second Print dialog comes up. I input a title in the Save As box. I choose Desktop in the Where box. I do not change anything else and select the "Save" button. A dialog appears that says, "Print Error while printing." There is an icon with paper, a pencil, a ruler and a paintbrush on the dialog.
Is this an issue with Apple and Java security? Does "run with limited access" mean I can't print and save as PDF? Should I upgrade to Mavericks? It seems like others have not been happy with Mavericks and have had problems saving as PDF with Mavericks. How do I let Apple know about this error? The error dialog is useless.
I am on a Mac running OS X 10.8.5 and Safari 6.1.2. My Java version is 7 update 51.
What other information can I provide to help solve the problem (if it can be solved)?
Thank you for your help!

I am trying to use an education program that needs Java applets to install and use and it will not use Safari. When I download IE from the web it will not install. How can I get a browser that will work on my MacAir for travel use of this program?

I am trying to use and education program that needs Java applets and it will not run on Safari. IE will not install from the web. How do I get a browser that will work to install so I can use this program when I travel.

Try using FireFox. IE will only run on a Mac if you run Windows on the Mac.
Windows on Intel Macs
There are presently several alternatives for running Windows on Intel Macs.
Install the Apple Boot Camp software. Purchase Windows 7 or Windows 8. Follow instructions in the Boot Camp documentation on installation of Boot Camp, creating Driver CD, and installing Windows. Boot Camp enables you to boot the computer into OS X or Windows.
Parallels Desktop for Mac and Windows XP, Vista Business, Vista Ultimate, or Windows 7. Parallels is software virtualization that enables running Windows concurrently with OS X.
VM Fusion and Windows XP, Vista Business, Vista Ultimate, or Windows 7. VM Fusion is software virtualization that enables running Windows concurrently with OS X.
CrossOver which enables running many Windows applications without having to install Windows. The Windows applications can run concurrently with OS X.
VirtualBox is a new Open Source freeware virtual machine such as VM Fusion and Parallels that was developed by Solaris. It is not as fully developed for the Mac as Parallels and VM Fusion.
Note that Parallels and VM Fusion can also run other operating systems such as Linux, Unix, OS/2, Solaris, etc. There are performance differences between dual-boot systems and virtualization. The latter tend to be a little slower (not much) and do not provide the video performance of the dual-boot system. See MacTech.com's Virtualization Benchmarking for comparisons of Boot Camp, Parallels, and VM Fusion. A more recent comparison of Parallels, VM Fusion, and Virtual Box is found at Virtualization Benchmarks- Parallels 10 vs. Fusion 7 vs. VirtualBox. Boot Camp is only available with Leopard and later. Except for Crossover and a couple of similar alternatives like DarWine you must have a valid installer disc for Windows.
You must also have an internal optical drive for installing Windows. Windows cannot be installed from an external optical drive.

Print- Save as PDF from Java applet on a webpage in Safari

I am on a Mac running OS X version 10.8.5 and Safari version 6.1.2. I am using the website www.wordle.net, which uses a Java applet to create a Wordle. The applet has a print button. The website FAQ says I should be able to save a Wordle as a PDF on a Mac. When I try to do this I get a small dialog that simply says "Error whilte printing."
Here is some of the system.log:

Print->Save to PDF works from Pages
Help! I want to make Wordles for the teachers at my kids school for Teacher Appreciation Week.

YES!!!!!!!
I was pulling my hair out last night over this. I noticed the Find function was not working properly. I KNEW there was something in the PDF and Preview was not showing it. I spent 2 hours trying to find someone with a similar Find function problem, but could not find much. Also, it could not copy and paste text. I KNOW it worked before because I had taken notes on this particular PDF and had copy and pasted whole paragraphs for myself into Pages. Which is what got me searching online tonight.
I re-downloaded the same PDF. When first opened in Preview, the Find and copy/paste functions worked. Same thing in Acrobat reader and Acrobat Pro. After confirming this, I re-opened it in Preview, highlighted some text and closed. It asked to Save Changes and I did. I immediately re-opened it, and guess what? Find no longer works and neither does copy/paste. Just to be sure, I tried re-opening in Acrobat reader and Pro; same thing. No copy/paste, corrupted Find feature. Well, copy/paste sort of functions, its just that it pastes a square with an alien head in it that says "Private Use 100000 Plane 16".
And finally, on some PDFs that have not even been saved in Preview, the Find function is not working properly also. It happened on the re-downloaded PDF I just talked about. It finds many instances of the word, bit the left and right arrows next to "Found on X# Pages are greyed out and do not move through the document. Once I go to the left pane that displays page thumbnails and click on a few different ones, THEN it starts working.
So yes, Apple, Preview is corrupting PDF files upon save, AND it is not working properly on other files. Please fix this. PLEASE.
And my specs are the same as Gary; iMac 27 inch Late 2009, Yosemite 10.10.1. Is ANYONE else having this issue with a different Mac?

Java applets wont load in Safari and constantly crash in Firefox

I have to use Java Applets to work from home. I normally use Firefox as my browser but since the last Java update Forefox keeps crashing. I have tried Safari too and it wont load the applets at all. I am desperate to get some work done but I can't get into my work files that are stored on my office's servers.
I have seen lots of discussion about enabling java etc. in my browser and all of that has been done.

Make sure your Java system is updated on both sides (home and work computers).
As an alternative, you might look into a non-Java VPN solution. I use RealVNC (free for up to 5 computers) to work from home on my Macs and connetc to WinXP and Win7 systems at work. It works beautifully and I can connect to all 4 work systems simultaniously! The only thing the free version won't do is print remotely... so I print to PDF in my Dropbox and print that at home.
For VPN, I use a Cisco RV042 4 port router (about $90 at BestBuy) and connect via the built in OS X VPN in the Network Preferences panel. It literally took less than 5 minutes to set up. Sweet, simple, minimal cost and setup, and I can work from the house 24/7 if needed.

Java Applet not loading in Safari

Hi folks.
I just noticed a problem with Safari on my Macbook Pro. I'm trying to use Keepvid to download videos from Youtube but it no longer works.
I load then link into Keepvid and then get the message "Java Applet Loading..". Except that it remains stuck like this forever and it does not work at all.
How to fix this please?

I have exactly the same problem.

I'm also using zonealarm as a firewall.
any Ideas?

Safari for Mac, webpage with Java applet, drag and drop area not working.

At my company, we have a web page that our users access to submit media files, (QuickTime, Audio, images...), for transcoding for delivery. The web page consists of a java applet, with an area that our users drag and drop media file into.
After updating to Safari 5.1.2, the applet will not work anymore. Instead, the browser will "open" the quicktime and play it, instead of allowing the Java Applet to do it's job.
CAN I TURN THIS FUNCTIONALITY OFF??
I read that Safari 5.1.2, (when it was initially released), broke something with the THEN current version of Java, and everyone was awaiting the latest update (build 1.6.0_29) to fix it. Unfortunately, this update did not fix my issue with the functionality of dragging and dropping media files into the web page.
It seems to me, as if, there is an over-arching functionality setting (or something) that needs to be either turned off, or in some other way DE-prioritized.
Anyone have any ideas?

Java applets won't run on Safari???

I have reinstalled Java twice, and it still won't run any Java applets. It just sits there with the cup logo and the arrow on either side. It works fine on Firefox but not Safari. Help?

Hello
I'm piggy backing on this thread because I too have had problems with Java and Safari
Java runs fine for me in Firefox, however.
I went to a federal website
https://blrscr3.egs-seg.gc.ca/gol-ged/gov/browserdetection/BrowserCheck.html
that uses java and received this message
" Java applet unable to load
To use this service, you must either install a recent version of the Sun JVM or enable "Scripting of Java applets" if it has been disabled."
so i looked for an update and have downloaded and installed release 6, (at least, it said that it was installed, but have never been able to figure out where)
when I check Java preferences, the choices are J2SE 1.4.2 or J2SE 5, and when I've switched to 1.4.2 I still have no luck.
When i run firefox, i get the java console opening, but it doesn't open with safari, and I can't find the option for this to turn on in safari
i have restarted both safari and my computer and no luck. I have repaired permissions and no changes have taken place.
Any more suggestions?
(thank you, by the way)

Is running local Java applets disabled in Safari 6?

Ever since updating to Mountain Lion—and Safari 6—locally stored Java applets don't work any more. A quick test in JavaScript:
navigator.javaEnabled();
returns FALSE if the page is on the file server, and TRUE if the exact same page comes from a web server. Unfortunately these pages can't be delivered over a web server, they have to run from a file server.
Anyone know how to get applets to run locally in Safari? I've opened up Gatekeeper to run all apps and poked around the Java settings to no luck. I don't even get a "Inactive Plug-in" message, just...nothing. Am running both the Apple JRE6 as well as the most recent Oracle version 7u7.
Cheers

Java is locked down SO tightly now. I had local Java applets that ran fine in Firefox but wouldn't run in Safari. My friend did a little troubleshooting with me and figured this out:
1) In Safari > Preferences > Advanced, check "Show Develop menu in menu bar"
2) In Safari > Develop, select "Disable Local File Restriction"
Hope this helps!
