Java applet in Mac OS

Hello. There was a problem in applet under Mac OS. The problem is that if I call the dialog from an applet, then close the dialog applet does not receive the focus and have to again click on the applet.
What can I do? Or should we write AppleScript applet to transfer the focus after the dialog is closed

Oracle does not provide JRE for Mac OS X (at this moment).
It may work better if you ask for advice on Apple's Java forum.

Running a Java Applet on Mac OS browser

I'm having trouble getting my Java Applet to work properly on the Mac OS version of IE5. Basicaly, the app fails to appear. Are there any do's and don'ts regarding the running of Java Applets on Mac Browsers?
I read somewhere that you can't send parameters through to the Applet. Is that true? I'm not trying to do this and it's still doesn't work.
Any help would be appreciated.

If anyone can help me with this problem I would be greatful.

Safari will not run a signed applet on mac os x 10.5.7 with new Java update

Hi Everyone,
I've got a problem that hopefully you guys can help me solve. I have an applet that runs on windows, mac and linux that is signed by a verisign certificate my work has. The certificate is valid and everything works just fine on windows and linux, but after I upgraded our macs with the newest java update for mac (which gave macs Java 1.6.13), the applets won't work. When the applet is loaded in Safari or Firefox, it asks if I want to trust the certificate. When I tell it to trust it, Safari comes back with a message saying that it will not trust the code and will treat it as unsigned code.
For a long time the applet was built and signed on windows, but now it can be built and signed on windows and mac. Building and signing on either platform gives the same results and the mac signed applet works just fine on windows.
Has anyone else run across this problem? Any help or advice will be appreciated.
Thanks,
Robbie

How did you tell it to fully trust it? I thought the dialog comes up asking the user whether to trust it.
I only ask because it's not practical to expect all users to dig around for settings to trust a particular certificate.They don't have to dig around. When a signed Applet is loaded, if the certificate chain contains a certificate not in the trust store then a dialogue box asks the user if he wants to run it anyway. This dialogue box also has check box to indicate the the user should always trust this certificate and checking this means the user will not be asked again.

JDK 1.4.2 java applet image printing on mac safari

Hi there,
I'm trying to implement printing inside java applet using javax.print package. I read an article somewhere about the package not working perfectly under mac, and a workaround is to use the old java.awt.print to get the print services, then use the DocPrintJob to print.
The SimpleDoc I use for capturing the image that I need to print works fine, and the printServices are there. The problem I have is it's giving me an 'invalid flavor' exception when clicking 'Print' on popup PrintDialog.
It seems that the mimetype is what's causing the problem, as the printer's supported mime type is "application/x-java-jvm-local-objectref". (note that, on PC the printing works fine, with Doc flavor mimetype as image/png and the image I need to print in png format). I tried switching the flavor to SERVICE_FORMATTED.RENDERABLE_IMAGE, printing an ImageDoc class which implements Doc and RenderableImage, but 'invalid flavor' exception still occurs.
I don't know much about printers on Mac, so I'm not sure what I can do about it, is it something that can be controlled from the Applet or it's something that the user has to set in the system - the Applet can only warn the user and tell the user to do the configuration.
Thanks in advance!

SwingUtilities.updateComponentTreeUI() works by first updating the UI of the given component, and then updating the component's children (and their children). So first it will update the JToolBar's UI (which installs the appropriate borders on its buttons), and then it will update each button's UI (which subsequently installs its own default border onto the button, undoing JToolBar's border installation, thanks to the bug mentioned previously).
Another possible work-around for this problem would be to write your own updateComponentTreeUI() method that updates the child components' UI's before updating the parent component's UI:public static void newUpdateComponentTreeUI(Component c)
     updateTreeUIs(c);
     c.invalidate();
     c.validate();
     c.repaint();
private static void updateTreeUIs(Component c)
     Component[] children = null;
     if (c instanceof JMenu) children = ((JMenu)c).getMenuComponents();
     else if (c instanceof Container) children = ((Container)c).getComponents();
     // Children first...
     for (int i=0; children != null && i < children.length; i++)
          updateTreeUIs(children);
     // Parent last...
     if (c instanceof JComponent) ((JComponent)c).updateUI();
}Not sure if this will present any other conflicts though.

I have a Mac running OS X 10.6.8 and have installed all updates and disabled Java Applets. Do I need to put virus protection on this computer and, if so, any recommendations?

I have a Mac running OS X 10.6.8 and have installed all updates and have disabled Java Applets. Do I need to install antivirus software and, if so, do you have a recommendation on what works best.

Mac OS X versions 10.6.7 and later have built-in detection of known Mac malware in downloaded files. The recognition database is automatically updated once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders. In most cases, there’s no benefit from any other automated protection against malware.
The most effective defense against malware is your own intelligence. All known malware that affects a fully-updated installation of Mac OS X 10.6 or later takes the form of trojans, which can only work if the victim is duped into running them. If you're smarter than the malware attacker thinks you are, you won't be duped. That means, primarily, that you never install software from an untrustworthy source. How do you know a source is untrustworthy?
Any website that prompts you to install a “codec,” “plug-in,” or “certificate” that comes from that same site, or an unknown site, merely in order to use the site, is untrustworthy.
A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim.
“Cracked” versions of commercial software downloaded from a bittorrent are likely to be infected.
Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. No intermediary is acceptable.
Disable Java (not JavaScript) in your web browser(s). Few websites have Java content nowadays, so you won’t be missing much. This setting is mandatory in Mac OS X 10.5.8 or earlier, because Java in those versions has bugs that make it unsafe to use on the Internet. Those bugs will probably never be fixed, because those older operating systems are no longer being maintained by Apple. Migrate to a newer version of the Mac OS as soon as you can.
Follow these guidelines, and you’ll be as safe from malware as you can reasonably be.
Never install any commercial "anti-virus" products for the Mac, as they all do more harm than good. If you need to be able to detect Windows malware in your files, use ClamXav — nothing else.

Java applet freezes while loading on Firefox on Mac OS 10.9

I am using Mac OS 10.9.4 with Firefox 32 and Java 7 update 67. The java applet freezes while loading for the first time. On double clicking, it loads successfully. Once the applet gets loaded then it loads successfully until the web-page is refreshed or cache is cleared. I don't see any error message or any errors in the java console logs. Any help on this issue, apart from the double click work around? Any permanent solution?

This delay can also happen when Java has been unloaded from memory and needs to be reloaded from disk and (re)initialized.
You may be tight on available (free) memory if this happens all the time.

HT5642 Java applet doesn't work on my Mac

I have the new Mountain Lion 10.82 software version on my Mac as I needed it to be able to use java applet update 11. I downloaded and installed the security fix java update 11 on 27th January 2013 and it worked for a couple of days fine but now a sign with "blocked plug-in" appears. Even after installing it again it doesn't seem to work. Could anybody please help me?

There's apparently another security bug in Java.
Depending on what you're working with, you may be able to download and invoke the application outside of the browser — such as can be done with Minecraft — or you can both enable the Java JVM plug-in within the browser and also disable the version-check defenses in Xprotect (see the comments here for details) that are blocking the Java webstart stuff (again), if you need to run that stuff from the web browser.
Otherwise, Oracle will likely be providing an update to block the most recent attacks.
There are two other potential wrinkles here, where the Java JVM web plug-in disables itself after some interval of non-use, and there are also diagnostics issued when launching an app that isn't signed by a developer ID from Apple. Java checks for its own signatures, and Apple checks for its signatures, and the Java apps aren't signed with the Apple keys.

When using Java Wizard with Firefox 3.6.23 on a Mac OS X 10.6.8 it keep getting an error message: "The Java Wizard cannot run. Please configure your browser to allow Java applets to access the filesystem." Have NO idea how to fix this problem.

When trying to upload files I received the following error: "The Java Wizard cannot run. Please configure your browser to allow Java applets to access the filesystem."

If the problem is with a site that is hosted using MOVEit DMZ by Ipswitch, please notify the site owner of the issue and ask them to apply the patch that is available on the support site to resolve the issue.
This is a better resolution than downgrading your version of Java that was updated due to security issues.

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?
Safari 5.1.2
MacOS 10.6.8

Thanks for quick reply and help. I am able to drag multiple files but this is giving problem in case of filename with spaces like "abc def.png". Can you please put some thoughts on this.
DataFlavor uriListFlavor = new DataFlavor("text/uri-list;class=java.lang.String");
               Reader in = (Reader)t.getTransferData(DataFlavor.plainTextFlavor);
               BufferedReader br = new BufferedReader(in);
               String uriStr;
               while ((uriStr = br.readLine()) != null)
                   URL url = new URL(uriStr);
                   String category = GalleryUtils.contentsPanel.getCurrentCategoryPath();
                   GalleryUtils.generateILPFromFile(new File(url.getFile()), category);

On a Mac Java applets not working on FF 31, have not worked since FF26; how to fix?

KeepVid, Quietube, Pin It, and placeholders on most websites instead of Java applets. Running Mavericks and Mountain Lion on an iMac and MacAir, and the applets don't work on either - they haven't worked since FF26. Plug-in is installed, and "always activate" in on. Anyone know what's going on and how to fix this?

I know of two settings associated with Java, maybe we can start there?
About:addons and then go to "extensions". Look for the Java plugin and make sure it is activated.
After this you can go to the Java options to make sure that it is active and check if it is up to date here [https://www.mozilla.org/en-US/plugincheck/]
[https://support.mozilla.org/en-US/kb/how-allow-java-trusted-sites How to allow Java on Trusted Sites in Firefox] may also be helpful.

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!

Correction I would like to save as PDF/A-1b
for archiving.

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.

Printing problem on java applet

Hi, I'm Korean and MacBook air user.
I'm very not good at English, please excuse me .
I use OS X 10.8.3 and jdk 7.
I make a simple java applet program includes printing functionary.
But, only browsers (Safari and FireFox) on Mac OS X not printing font correctly.
I use setFont() function and then drawString() function.
If you cannot understand my question, enter the link below. I think that question is same with my question.
http://stackoverflow.com/questions/15466060/java-app-on-mac-os-x-not-printing-fo nts-correctly
Thank you for reading my question.

Points/questions.
It is a lot easier to debug these things if we can see the applet. Is it on the net? Can you give us the URL?
Have you considered launching this applet using web start? (If it turns out to be related to security, the web
start JNLP API has a neat way to sidestep that problem.)
Edit 1: Deleted the entire first two paragraphs when realised you said 'always prints'.
