Black screen on java

when i try to enter some irc channels which are using java, i get black screen instead the chat screen. it's not like the script doesn't work at all, but all i can see is some of the words. it works perfect on my desktop pc, but not on my macbook pro. my java is up to date. what should i do?

Performing a plug-in check and updating to the latest version of Adobe Shockwave should fix the problem.

Black Screen with cursor. Java Desktop System.

Hello everyone.
I've installed Solaris 10 05/08 x86 32bit in VMWare Workstation 6.5.
After I logged in in the system (Java Desktop System, Release 3), I've got only a black screen with cursor, nothing more.
X server: Xsun server configuration:
Video Device: VMWare Inc vmware0405

Hi
Have you installed all the Recommended Patchset . If not try to install the patches .
Regards

To open "Java Preferences," you need to install a Java runtime, but you are not connected to the Internet. I have tried links that people have put on other discussions but all i get is a black screen please help!!

JAVA BLACK SCREEN

WHEN I TRY TO PLAY GAMES THAT USE JAVA THE GAME COMES UP AND THEN WHEN JAVA IS SUPPOSE TO COME UP I GET A BLACK SCREEN AND IT DOESN' T GO ANY FURTHER. WHEN I TRY TO UNINSTALL JAVA SO I CAN REINSTALL IT A MESSAGE COMES UP SAYING THAT I ALREADY HAVE IT , AND TO UNINSTALL IT BEFORE TRYING TO INSTALL. CAN ANYONE HELP?

Try the following:
1. Update Windows DirectX to the latest version.
2. Update your video drivers to the latest version.
3. Set your video driver to Application-controlled for Ant-Aliasing and Anisotropic filtering instead of overriding it.

My iMac 8.1 was slowing down and had permissions problems. I backed everything up, and then re-installed. Now all I get is a black screen. Power+D gives me a hardware error message: HDD-1336. Help!

My iMac 8.1 (10.6.8 ) was slowing down and had recurrent permissions problems, mostly with Java. I backed everything up, and then re-installed from time machine. Now all I get is a black screen which says I need to reboot. Power+D gives me a hardware error message: 4 MOT/1/40000003: HDD-1336 or HDD-1327. When I reboot from the OSX CD and start disc utilities everything checks out OK. When I reload 10.5.2 from the OSX CD everything seems to work OK and no more permissions problems. But then I loose all my email and safari stuff. Anyone have any ideas short of going back to my old PC?

Hi
Thanks for the help. No point in fooling around with it any more. Will I be able to use it as a monitor if I get a mimi mac?
Cheers. Don
No unfortunatley it's too old, you are referring to Target Display Mode which became avialble in 2009, your 2008 needs to have the HD replaced. I'd still do that if everything else is OK or you can simply buy a new MM and display or even a new iMac or an Apple refurbished iMac to save money.

Screen problems - black screen and lock-up (plus HDMI issues)

Hi, I'm not sure if these are related to the same fundamental issue, but they are both serious problems that need resolution.
I have a new mid-2012 MBPretina. I am on all the latest updates (10.8.2).
The first problem is the most recent, and the most serious problem. Since I updated the Java a couple of days ago I've been experiencing random black screens and lock-ups. Essentially, what happens is that sometimes when I perform an action (opening an app, clicking a link on a webpage, performing other kinds of in-app actions, etc.) the computer screen will go black. About half the time I can, through my own memory, try keyboard combinations to quit or force quit the most recently used app (the one where the action was just performed), and I will get some glimpse of the underlying apps, while the menubar and other areas will remain black until I move a window on top of the black space. Sometimes no key combinations work and I am forced to perform a hard restart with the power button. This is a serious issue, obviously, since I will lose current work/progress in my apps. I'm not sure if this is because of the new Java update, or has to do with something else, but it started happening shortly thereafter, over the last 2 days. I work most of my waking day on my laptop, and this "black screen of death" has happened about 5 or 6 times a day.
The second problem I have been experiencing since I starting using my MBPr with external HDMI displays in August/September. The problem is that I will plug the MBPr into an HDMI display, the screen will temporaliy go black, and then bring me to the login screen (as if it's crashing, albeit softly). This happens about 1 out of 4 times nowadays.
How can I fix these problems, especially the first?

UPDATE:
Clearly there's a problem because a third of the way through a clean reinstallation from scratch it black screened again. Hmmmm.
Now this is not good. Problem is I can't rule out potential updates from Apple that might have caused this either.
The search for solutions continues.

Black screen after login / after sleep

Hoping somebody can help, I've spent like the last two days straight at the genius bar without success. When I boot up I see my profile and the guest, it boots as normal (not the delayed boot with black screen others have mentioned), but then I log in, see my desktop, icons, and then the screen goes black.
If I let it sleep for a few hours, when I wake it up the screen is also black and there's nothing I can do except hold the power till it shuts down.
In both cases I can tell the computer is still on because the backlit keyboard stays lit.
I've tried resetting nvram, smc, deleting the library cache file, doing a is reinstall without wipe, and I only have one partition/HD so it's definitely the default boot disc.
I can boot into safe mode, and occasionally boot up regularly after being in safe mode for a bit.
I had the display replaced due to a physical defect just before this happened, but I also got 10.10.3, which I know has caused graphics glitches for other people.
Hope you guys have some ideas! Thank you!

Mac users often ask whether they should install "anti-virus" (AV) software. The usual answer is "no." That answer is right, but it may give the wrong impression that there is no threat from what are loosely called "viruses." There is a threat, and you need to educate yourself about it.
1. This is a comment on what you should—and should not—do to protect yourself from malicious software ("malware") that circulates on the Internet and gets onto a computer as an unintended consequence of the user's actions.
It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the computer, or who has been able to take control of it remotely. That threat is in a different category, and there's no easy way to defend against it. AV software is not intended to, and does not, defend against such attacks.
The comment is long because the issue is complex. The key points are in sections 5, 6, and 10.
OS X now implements three layers of built-in protection specifically against malware, not counting runtime protections such as execute disable, sandboxing, system library randomization, and address space layout randomization that may also guard against other kinds of exploits.
2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user. Internally Apple calls it "XProtect."
The malware recognition database used by XProtect is automatically updated; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
The following caveats apply to XProtect:
☞ It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets.
☞ It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
As new versions of OS X are released, it's not clear whether Apple will indefinitely continue to maintain the XProtect database of older versions such as 10.6. The security of obsolete system versions may eventually be degraded. Security updates to the code of obsolete systems will stop being released at some point, and that may leave them open to other kinds of attack besides malware.
3. Starting with OS X 10.7.5, there has been a second layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't been checked for security by Apple unless it comes from the App Store, but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. That may not mean much if the developer lives in a country with a weak legal system (see below.)
Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following:
☞ It can easily be disabled or overridden by the user.
☞ A malware attacker could get control of a code-signing certificate under false pretenses, or could simply ignore the consequences of distributing codesigned malware.
☞ An App Store developer could find a way to bypass Apple's oversight, or the oversight could fail due to human error.
Apple has taken far too long to revoke the codesigning certificates of some known abusers, thereby diluting the value of Gatekeeper and the Developer ID program. Those lapses don't involve App Store products, however.
For the reasons given, App Store products, and—to a lesser extent—other applications recognized by Gatekeeper as signed, are safer than others, but they can't be considered absolutely safe. "Sandboxed" applications may prompt for access to private data, such as your contacts, or for access to the network. Think before granting that access. Sandbox security is based on user input. Never click through any request for authorization without thinking.
4. Starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background when you update the OS. It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is effective against known threats, but not against unknown ones. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
5. The built-in security features of OS X reduce the risk of malware attack, but they are not, and never will be, complete protection. Malware is a problem of human behavior, not machine behavior, and no technological fix alone is going to solve it. Trusting software to protect you will only make you more vulnerable.
The best defense is always going to be your own intelligence. With the possible exception of Java exploits, all known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "Trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and Internet criminals. If you're better informed than they think you are, you'll win. That means, in practice, that you always stay within a safe harbor of computing practices. How do you know when you're leaving the safe harbor? Below are some warning signs of danger.
Software from an untrustworthy source
☞ Software with a corporate brand, such as Adobe Flash Player, doesn't come directly from the developer’s website. Do not trust an alert from any website to update Flash, or your browser, or any other software. A genuine alert that Flash is outdated and blocked is shown on this support page. Follow the instructions on the support page in that case. Otherwise, assume that the alert is fake and someone is trying to scam you into installing malware. If you see such alerts on more than one website, ask for instructions.
☞ Software of any kind is distributed via BitTorrent, or Usenet, or on a website that also distributes pirated music or movies.
☞ Rogue websites such as Softonic, Soft32, and CNET Download distribute free applications that have been packaged in a superfluous "installer."
☞ The software is advertised by means of spam or intrusive web ads. Any ad, on any site, that includes a direct link to a download should be ignored.
Software that is plainly illegal or does something illegal
☞ High-priced commercial software such as Photoshop is "cracked" or "free."
☞ An application helps you to infringe copyright, for instance by circumventing the copy protection on commercial software, or saving streamed media for reuse without permission. All "YouTube downloaders" are in this category, though not all are necessarily malicious.
Conditional or unsolicited offers from strangers
☞ A telephone caller or a web page tells you that you have a “virus” and offers to help you remove it. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
☞ A web site offers free content such as video or music, but to use it you must install a “codec,” “plug-in,” "player," "downloader," "extractor," or “certificate” that comes from that same site, or an unknown one.
☞ You win a prize in a contest you never entered.
☞ Someone on a message board such as this one is eager to help you, but only if you download an application of his choosing.
☞ A "FREE WI-FI !!!" network advertises itself in a public place such as an airport, but is not provided by the management.
☞ Anything online that you would expect to pay for is "free."
Unexpected events
☞ A file is downloaded automatically when you visit a web page, with no other action on your part. Delete any such file without opening it.
☞ You open what you think is a document and get an alert that it's "an application downloaded from the Internet." Click Cancel and delete the file. Even if you don't get the alert, you should still delete any file that isn't what you expected it to be.
☞ An application does something you don't expect, such as asking for permission to access your contacts, your location, or the Internet for no obvious reason.
☞ Software is attached to email that you didn't request, even if it comes (or seems to come) from someone you trust.
I don't say that leaving the safe harbor just once will necessarily result in disaster, but making a habit of it will weaken your defenses against malware attack. Any of the above scenarios should, at the very least, make you uncomfortable.
6. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was always a bad idea, and Java's developers have proven themselves incapable of implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style virus affecting OS X. Merely loading a page with malicious Java content could be harmful.
Fortunately, client-side Java on the Web is obsolete and mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other non-essential uses of Java.
Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it—not JavaScript—in your browsers.
Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a task on a specific site, enable Java only for that site in Safari. Never enable Java for a public website that carries third-party advertising. Use it only on well-known, login-protected, secure websites without ads. In Safari 6 or later, you'll see a padlock icon in the address bar when visiting a secure site.
Stay within the safe harbor, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself.
7. Never install any commercial AV or "Internet security" products for the Mac, as they are all worse than useless. If you need to be able to detect Windows malware in your files, use one of the free security apps in the Mac App Store—nothing else.
Why shouldn't you use commercial AV products?
☞ To recognize malware, the software depends on a database of known threats, which is always at least a day out of date. This technique is a proven failure, as a major AV software vendor has admitted. Most attacks are "zero-day"—that is, previously unknown. Recognition-based AV does not defend against such attacks, and the enterprise IT industry is coming to the realization that traditional AV software is worthless.
☞ Its design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere. In order to meet that nonexistent threat, commercial AV software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
☞ By modifying the operating system, the software may also create weaknesses that could be exploited by malware attackers.
☞ Most importantly, a false sense of security is dangerous.
8. An AV product from the App Store, such as "ClamXav," has the same drawback as the commercial suites of being always out of date, but it does not inject low-level code into the operating system. That doesn't mean it's entirely harmless. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
An AV app is not needed, and cannot be relied upon, for protection against OS X malware. It's useful, if at all, only for detecting Windows malware, and even for that use it's not really effective, because new Windows malware is emerging much faster than OS X malware.
Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else. A malicious attachment in email is usually easy to recognize by the name alone. An actual example:
London Terror Moovie.avi [124 spaces] Checked By Norton Antivirus.exe
You don't need software to tell you that's a Windows trojan. Software may be able to tell you which trojan it is, but who cares? In practice, there's no reason to use recognition software unless an organizational policy requires it. Windows malware is so widespread that you should assume it's in every email attachment until proven otherwise. Nevertheless, ClamXav or a similar product from the App Store may serve a purpose if it satisfies an ill-informed network administrator who says you must run some kind of AV application. It's free and it won't handicap the system.
The ClamXav developer won't try to "upsell" you to a paid version of the product. Other developers may do that. Don't be upsold. For one thing, you should not pay to protect Windows users from the consequences of their choice of computing platform. For another, a paid upgrade from a free app will probably have all the disadvantages mentioned in section 7.
9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.
10. As a Mac user, you don't have to live in fear that your computer may be infected every time you install software, read email, or visit a web page. But neither can you assume that you will always be safe from exploitation, no matter what you do. Navigating the Internet is like walking the streets of a big city. It can be as safe or as dangerous as you choose to make it. The greatest harm done by security software is precisely its selling point: it makes people feel safe. They may then feel safe enough to take risks from which the software doesn't protect them. Nothing can lessen the need for safe computing practices.

Black screen upon waking Mac

Mac Mini 2011 with 2x4GB RAM, 2.3Ghz i5, 500GB 5400RPM HDD
So I need some help regarding my Mac and it's driving me mad! Its a bit tempermental and it isnt always the same occurance each time, but basically symptons are (somtimes it occurs, sometimes not with each one!):
Turning on It will freeze on white screen (no logo)
upon waking up from sleep it will display black screen with mouse and notifications. no login UI or wallpaper. Can SOMETIMES login if i just type password (as if login screen is still there). mouse dissapears once typing begins
Sometimes when the previous event occurs (^) and i put computer to sleep it will then do the opposite and display just the wallpaper with no input from mouse, keyboard
I have tried removing all devices (webcam, USB mouse etc) and turning on computer but as its tempermental
I have also reinstalled a new OS X over the top from internet recovery
Also reformated HDD and restored OS X.
Also reset SMC and NVRAM.
Also checked in
/private/var/run/StartupItems   -doesnt exsist
/Library/StartupItems - nothing in this folder
/System/Library/StartupItems - nothing either
/System/Library/LaunchDaemons - Loads of files in this folder
/Library/LaunchDaemons - only a few files
Also only 3rd party pref are Java and Flash.
Internet Plug-ins:

Also run the AHT extended test, no issues detected.
Also set "sudo pmset autopoweroff 0" and "sudo pmset standby 0" in Kernal.
Also repaired disk permissions, it only repaired the printer stuff.
After i gave this in kernal, i then reset SMC again to check.
Checked console and noticed a 40 second gap before this error:   "05/02/2014 07:03:00.266 configd[55]: inet_set_autoaddr(en1, 1) failed, Resource busy"
turned off my WiFi and issues still persisted.
This had previously been on forums last week in Mac Mini section with the help of 'BDAqua' however im out of options and need some more help. If anyone could be helpful enough to give some suggestions on why my screen is black upon waking up (exc. notifications. they appear) and most time i need to hard reboot (sometimes i can type in password and it unlocks).
I can not afford to start fresh, i have a 110GB iTunes Library with 210 iOS apps and photos too important to me to be forgotten.
PLEASE HELP ME

Try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work. The intent is to see if it is specific to one account or a system wide problem. This account can be deleted later.
Isolating an issue by using another user account
If the problem is still there, try booting into the Safe Mode using your normal account. Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up after waiting 10 seconds. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application un-installer. For each disable/delete, you will need to restart if you don't do them all at once.

Black screen when running MIDlets on a real phone (motorola V330)

Hello.
I'm developing a simple Java ME application as a part of my senior project in college. Up until this point I've been working with emulators and everything works fine. Yesterday I tried to upload and test my application on my old phone - Motorola V330 (CLDC 1.0 MIDP 2.0).
I can upload and install MIDlets without problems. (Using unlocked application loader and a USB cable). When I try to start them, the screen goes black and stays black. If I hit the "exit" softbutton or the red power button, I can see my application for a split second before the program exits. For example if I try to run a game, I see the game screen for a split second, if I try to run a form, I see that form. That tells me that the application can start, but I dont know why I get a black screen.
I tried that with a bunch of applications, even for a simple form with "hello world" on it, the screen goes black.
I also tried some games from SUN examples and I have the same problem.
Anybody can give me any hints on how to solve the problem? Could this be the phone issue or is it some sort of security certificate issue?
I tried googling the issue and searching these boards but I cant find any concrete solutions.
PS. The phone is old and is no longer connected to the network, but it still has a sim card.

Yeah, it's CLDC1.0 and MIDP 2.0.
I've looked at the phone again and found out that in "Java settings" menu the "backlight" option was turned off by default. Turning it on allows me to see my java apps. So the problem is solved.
When I had similar problems with my laptop (black screen, barely visible text) it took me a ridiculous amount of time to talk to technicians over the phone and try to explain to them what I'm seeing. Apparently the problem was the same - the backlight on my laptop's display was malfunctioning. I hope this info will help some of you or at least will help you googling stuff if you ever encounter the same problem.

Update=black screen on restart

Did software update this AM (daylight savings, java, quicktime & security update) everything seemed fine. Clicked on restart as required - now I only get a black screen that says:
Darwin/BSD (G4-GM.local) (console)
Login:
I've entered the administrator name & password and
no home directory and something else
briefly appear, a blue screen shows then back to black as above.
I'm guessing that the home directory was renamed? but don't know how to get past this black screen! I don't have a 10.3 Install disk (bought computer used) but have a 10.4 Install set from my imac at home. Can I do anything? It's the boss's computer that's screwed!

Betsy:
Michael Conniff has worked on a number of these situations. Here is a list of recent posts from Michael. Hopefully you will be able to find help in them.
When I had a similar issue a while ago I ended up having to do a complete reinstall. Here's a link to that thread.
Let me know if anything works.
Good luck.

Re: A Black Screen

I've been running SDK 1.3.1 with j3d 1.3 at home on Windows XP and it all works fine. I've tried running the same program at work on windows 2000 and although the program executes all I get is a black screen. I know the program IS running though as my debug messages still come up in the console window... Anybody got a solution?
Thanks.

There is a certain combination of versions of jdk and j3d where you need specific maintenance releases in order to get it to run properly. I'm not quite sure if it is jdk 1.4 with j3d 1.2.1 or jdk 1.3.1 with j3d 1.3. Check the mail archive for this issue: http://archives.java.sun.com/archives/java3d-interest.html

Why do some of the pdf files I try to open just display a black screen?

Black screen in Firefox 3.6.13. Any way of opening pdf files?

With Adobe Reader X I'm unable to open pdf files in Firefox (or any other browser I've tried so far). I've uninstalled and reinstalled numerous times but I just get a completely black screen (grey in IE).
Anyone with a non-jargon filled answer for computer illiterates, please!

There are other things that need attention:
Your above posted system details show multiple Java Console extensions.<br />
You can uninstall (remove) the Java Console extensions and disable the Java Quick Starter extension, you do not need them to run Java applets.
See http://kb.mozillazine.org/Java#Multiple_Java_Console_extensions
Disable the Java Quick Starter extension: Tools -> Add-ons -> Extensions
Control Panel -> Java -> Advanced tab -> Miscellaneous -> Java Quick Starter (disable)
See http://www.java.com/en/download/help/quickstarter.xml - What is Java Quick Starter (JQS)? What is the benefit of running JQS? - 6.0
