Help, WinXP can't recognise JRE ?

To all
I've installed the j2sdk 1.4.2 with the NetBeans IDE to my WinXP, I can compile and run java programs, but somehow, the Web browser (IE 6) can't recognise I've installed j2sdk and so I can't run some java games hosted on the web
What's the problem ???
Thanks!
From Jason (Kusanagihk)

Hi Jason,
I've had several slightly different problems with client machines, the only constant in all cases is the machines were recently patched from Microsoft.
Some could no longer load Applets at all using the APPLET tag but worked with the OBJECT tag, This was solved by re-installing the MS JVM (which was a pig to find as Microsoft no longer have it on there site) onto the machines (which I assume should have no impact on the Sun JVM which was still installed and not touched)
This must have re-installed support for the APPLET tag and passed the applets onto the Sun JVM as they worked fine.
The other problem is a little trickier. The applet loads and starts but the connections to our databases (using an Easysoft JDBC-ODBC bridge which has been working for over 3 years!) failed.
I've contacted Easysoft to try and solve the problem and they had the same problem on one of their machines which was solved by upgrading to the latest Sun JVM (1.4.2_04).
Unfortunately the client I was dealing with already had this version and re-installing it made no difference. In the end this client had to set his machine to use the MS JVM which now works but is not a full solution.
I have just been talking to another client today who is having the same problem but using the MS JVM doesn't work either (with or without a firewall connected).
This is becoming a potentially serious problem for us as we have over 30 E-commerce sites that use Java extensively so as you can imagine, I need to get this solved.
I am trying to contact Sun, Microsoft and Easysoft to get some insight into the cause, I'll keep you posted (no pun on forums intended).
Any Ideas you have on this would be most appreciated.
Regards,
Alastair.

  • Macbook pro(2008 later) can not recognise external monitor(NEC UXI2090) with mini-DP to DVI adapter with 9600GT

    I bought mini-DP to DVI frome Apple several monthes ago and it worked well in that time until yesterday the external monitor show me no signal sign. Other PCs were connected with the same cable and monitor and they are fine. I am wondering there is something wrong in the adaptor or macbook pro. Furthermore I found the external monitor can display nornally when I switched to 9400 graphic card and used mini-DP to VGA adapter. If I switch to 9600GT no signal again. If I switch 9400 using mini-DVI, it is shown on the external screening: Out of range... In a word, In the mode of 9600GT, mac can not recognise external monitor(I can not detect it in the systerm preference even I press detect display buttun) and 9400 works in VGA mode. However when I connect adapter to mac, the screen showed blue flash.
    I reseted SMC, no use; I created a new account or enter mac to safe mode, no use; so far I did not reseted PRAM beacuse of something wrong of my system. I am downlaoding Mountain Lion OS and will install it. Then I will reset PRAM and try again.
    I do not know whether I shoud change the adapter or the single-link DVI cable to dual-link. Someone said it is useful in their condition. I tried some methods from BBS, such as connected when devices were off and then open, and so on. I failed.
    Any suggestion for this problem?
    Addition: OS: 10.7.4(Lion)

    I turns out that the logic board of my MacBook Pro was faulty (despite being brand new).
    I took it to the Apple Store, presented the problem, and one of the Tech's came to the same conclusion that I had -- hardware failure.  Phone support was no help in the matter (and even told me that what I was trying to do wasn't a supported option, which is rediculous).  However, the Genius Bar did take care of the problem, and my MacBook Pro was back to me with a replaced logic board within a few days.
    Hope that htis helps.

  • Help! Backups not recognised when attempting full restore

    I recently screwed up my Macbook while trying to mess about with partitions and the like, and I thought no problem simply reinstall and restore from time machine back ups.
    Slight problem. No OS X install disc, only a leopard upgrade one.
    So I used an old image cloned using superduper and copied that to Macintosh HD so now the main HD has a bootable image (btw I'm really not at all sure about the terminology here, it is the result of massive googling) as in it will turn on and work fine and dandy.
    But this image is from a long time ago and is missing lots of important stuff. So I try and restore it from my time machine back ups using the upgrade disc - and it doesn't work.
    Doesn't recognise anything as time machine back ups, it simply shows my external as an orange icon, not the green TM one, same on the desktop when I simply turn the computer on.
    Anyone know a way around this problem? You'll have my undying gratitude.
    Thanks in advance for any help you can give me!

    Well it shows up, but when I select it there seems to be no back ups that it recognises.
    But when I manually go into the drive the data is all there and correct :$ This is very annoying.
    Any suggestions?

  • How can I simplify JRE?

    I want my Java application released with JRE in order to support Green Software. But JRE 1.6.0 has 100m size, can I simplify JRE, remove something I don't use? Is there any tools can do that?
    Thanks.

    After install it, it will take 100mb size. For a green software, I don't want customer to install any thing in their computer.What's "green software", and how do you see trimming the JRE as helping? Why don't you want your customers to install anything? How can they run software without it being installed in some way?

  • BIOS update issue on Satellite Pro L40-15A - Old BIOS can't recognise EEPROM

    Hi
    I'm having trouble flashing my bios.
    I have a Satellite Pro L40-15A.
    The Toshiba winflash tool that comes with the bios file tells me that the 'Old BIOS can't recognise EEPROM'
    I was recommended to use AFUDOS on another forum but that tells me the bios has an invalid boot block.
    AMI flas for dos tells me the flash rom is write-protected??? There is no option in bios to disable it and I don't think anyone would be dumb enough to put a hardware Bios protect jumper on a laptop.
    Please help
    Thx

    Hi and thanks for reply
    The 5.10 bios update is only for XP laptops, my one came with windows vista installed so I need v2.20
    "old BIOS cannot recognise EEPROM" is the error message i get when i try to flash the bios with the supplied software from Toshiba
    _+UPDATE:+_
    New verion of BIOS update has worked!!
    Case could be closed

  • How do I get rid of the Microsoft Setup Assistant loop? I migrated my software/documents from another laptop so don't have the disk to reinstall. Please help! Can't open any Microsoft Office software, like Word, and stuck in a loop?

    I migrated my software/documents from another laptop so don't have the disk to reinstall. Please help! Can't open any Microsoft Office software, like Word (for 2008), and stuck in a loop?
    Whenever I select Word Microsoft Setup Assistant appears, asks for feedback, then after selecting okay (both on saying yes or no to feedback) goes on to a registration page. When I click on this it says I've already registered so I just click okay, and then move on to a update page. After this, if I click on Word, the process repeats itself.
    As I said, I don't have the disk to reinstall, and can't find the Office Settings to delete as many pages have suggested I should try. Safe Boot restarting also hasn't worked... Really stuck and need Word very soon for work.
    If you can help, that would be great, and feel free to ask any questions about the situation as I'm not an expert here.
    Cheers,
    Jack

    First, export your contact from iCloud.com and save them on your computer in a safe spot some where (like you desktop).  Use this to help you do this: http://support.apple.com/kb/PH3606
    Next, on both of your devices, go to Settings > iCloud and turn on contacts and select Merge. Then turn off contacts and select 'Delete form my [device]' when prompted.
    Now go back to iCloud.com and select a contact (yes they will all be messed up again) and select Command+A on a Mac or Control+A on a PC to select all of the contacts.  Tap the delete key on your keyboard (or right click /control click a contact and select delete).
    You iPhone, iPad and iCloud.com should not be empty for contacts.
    Go back to Settings > iCloud on both devices and turn on contacts again (you should not see merge this time).
    Next, go back to iCloud.com and import your contacts (those exported .vcards).  You can either drag and drop them into the empty contacts list in your web browser, or you can use the gear icon to import.
    You cleaned up contacts should import correctly into iCloud.com and sync to both of your devices.
    Good luck.

  • Pls help - How can I add a typekit font to muse?

    As Muse doesn't come with all typekit fonts already included in the dropdown list of webfonts, I'd like to know how I can add a typekit font to the dropdown menu so I can use it for my website. I have Adobe creative cloud membership.
    I've searched the whole of the web and can't find anything about this at all - only about adding one of the existing muse typekit fonts which I already know how to do.
    Why doesn't Adobe include all typekit fonts with Muse when you're already a full creative cloud subscriber?

    Done!

  • Help!Can't access iCloud (pics apps) even with correct password. Won't download my stored info on my new phone

    Help!Can't access iCloud (pics apps) even with correct password. Won't download my stored info on my new phone

    That happens because photo stream photos only remain in iCloud for 30 days, even though your last 1000 photo stream photos remain on your devices until deleted.  When you enabled photo stream on your iPod 4, you only received photo stream photos from the last 30 days as older photos are no longer in iCloud.  If you want to stream these older photos to your new iPod, you will have to create a shared photo stream on your old one that contains these photos (requires iOS 6 or higher) and invite yourself as a subscriber, as explained here: http://help.apple.com/icloud/#/mmc0cd7e99.

  • I have purchased a ringtone in the iTunes Store for my iPad, and I cannot find the download together with my music. I have received the invoice but I have no product. I am working with iOS6, if that helps. Can anybody help me?

    I have purchased a ringtone in the iTunes Store for my iPad, and I cannot find the download together with my music. I have received the invoice but I have no product. I am working with iOS6, if that helps. Can anybody help me?

    I am confused. Do you mean you found the music, not the tones, or you can't find either?
    If the former, then this is normal. You can't redownload tones from the Cloud.

  • Help I can only have max. 3 osx apps. open at the same time ?

    Help I can only have max. 3 apps. open at the same time ?
    If I have 3 apps. open, and try to open a 4th. this message comes up :
    The application "Mail" cannot be launched. -10810
    Of cause if I'm trying to open up something else than mail, lets say iPhoto, it will say "iPhoto".
    This is very weird to me, and I'm normally pretty good at solving issues myself, but I'm stuck with this one.
    Please help out

    I've had this quite a lot too. Do you find that under these conditions you can't load a disk image either?
    At first I put this down to Rosetta taking up a lot of resources. I was running OmniWeb with a lot of pages open in the workspaces so I've switched back to Safari until OmniWeb is UB. This morning I read that having Windows file sharing switched on helps to cause this problem. I switched this off, rebooted and ran disk utility to repair disk permissions and I've been running OK since then. I've currently got 13 apps open plus Finder and Widgets. They include 2 bigguns, Eclipse/MyEclipse and Visual Paradigm for UML. It'll probably stop working now I've written that.
    I run a MBP 17 with 2GB memory. My guess is that Windows file sharing does cause problems. I just hope Apple has resolved this in 10.4.7... whenever that is.

  • Help, I can't sync any music to my iPhone 5s or iPad 2 ! :( it says it's finished sync but the music is greyed out and not on my devices.. I've tried unchecking the music and doing it manually. Nothing works. I took it to Apple store Robina no help..

    Help, I can't sync any music to my iPhone 5s or iPad 2 ! it says it's finished sync but the music is greyed out and not on my devices.. I've tried unchecking the music and doing it manually. Nothing works. I took it to Apple store Robina no help..

    So I have found a common denominator to this phenomenon. After having the same problem, I started to recopy my playlist of 500+ songs in groups of 10-20, 30+, 75+, and then over a 100+. Any music I have purchased from iTunes won't copy, but everything else did. Unsure if I made a playlist called "Purchased" at some point or this is an iTunes default, I also noticed it had some of the songs contained in my other playlist and was showing on my iPhone. Regardless of what I did such as dragging music from that playlist to the other and clearing songs from that playlist, I removed it altogether from the iPhone itself vs. doing through iTunes. After that, music copied fine to my playlist.
    So, my theory is that iTunes is getting tripped up on purchased tracks already showing on the phone and all songs are showing grayed out/dotted circle because iTunes can't resolve the conflict with purchased tracks.
    Hope this makes sense and is helpful.

  • Help! Can't update iwork and imovie because "You have updates available for other accounts".

    I recently purchased Macbook Pro with iMovie, iwork keynotes, pages and numbers preloaded in the machine. Now the App Store icon indicates that I have updates available.  So when I open up app store and click update, I got an warning stating " You have updates avaialbe for other accounts - to update this application, sing in to the account you used to purchase it". 
    I called tech support.  I was told that I must have had another account.  But clearly I don't have another account.  I'm not alzheimer.  If I had another account, I would have remembered it.  I used the same account for ipod, iphone, itune for many many years.  So I went on the support communities for help.  I read some post saying I should add my hard drive to spotlight privacy, then remove it.  I tried it, it didn't work.  Some said I need to enable something by entering a script to the terminal.  I followed the steps, it didn't work. Then some other post said that I should delete the apps, then reinstall it.  So stupidly enough, I deleted keynotes to "TEST" if it works.  Guess what? I completed removed keynotes from my macbook.  I can't even recover it?! At least before I deleted it, I had the old version of keynotes although obsolete, still functional.  Now I removed it, I don't even know how to reinstall it. 
    So, I'm so update and dying for help.  Can someone please teach me how to make my Macbook understand that I only have one account and let me update iMovie and iwork? Also, how to restore the accidentally deleted Keynotes?
    Thank you!!!

    You're just going to have to get back to the support folks with your Apple ID problem - http://www.apple.com/support/appleid/.
    They should be able to rectify the problem.
