Applet doesn't work with IE, even tough I have plugin

I have an applet that work properly in appletviewer.
When I start it from IE, I only get an empty page.
I have j2sdk140_01 so the plugin is there. I have also tried the html Converter, but nothing works. Any suggestions what to do?
In the applet I have a background image (.jpg), JButtons, JLabels and a JTextField.

I have opened the Java plugin-Control Panel and the java plugin is activated.
Under the advanced tab I changed from the standard plugin to the JRE 1.4.0_01 in C:\Program\Java\jre1.4.0_01
My applet contains of a background image (.jpg), a Jtextfield and some JButtons. Now I can see the image but not the other components...
"Kevinja" says something about a Java-console. I have no such under "View" and I don't know what to enable under Internet Options. The only "thing" that has to do anything with java is the Java plugin and that one is activated.
Any suggestions what to do next?

    I copy the my html file which has this applet built-in to my local computer. The webpage can be openned and the applet running fine even with jre1.4.1. Why it didn't run with Jre1.4.1 and it did run with jre 1.3.1 when loading remotely? Could someone tell me what the above messages mean? Is this a bug from Jre1.4.1_01?
    Thanks,
    Kunlun

  • I use Firefox 3.6.12 and a Macbook Pro. Firefox doesn't work with some sites that need java plugin. What do I ?

    I Have Macbook Pro with Snow Leopard and all the softwares are updated. Safari works in the sites that Firefox doesn't work.

    Hi,
    You can try the latest in the [https://www.mozilla.org/en-US/firefox/all-older.html 3.6 series] which is still supported.

  • How do I switch back to 3.6? I use Norton 360 and it doesn't work with Firefox 4. I have uninstalled 4 and try to reinstall 3.6 from my downloads but it deleted 3.6 exe when it installed 4. I WANT 3.6 BACK.

    Norton isn't supported on Firefox 4. I don't trust ANY web browser that I can't use Norton on. I had no complaints with it when I had Firefox 3.6. I want to reinstall 3.6 but can't. I have looked all over for a download but every one comes back to Firefox 4.

    Symantec need to update their Firefox add-ons so that they are compatible with Firefox 4. They have indicated that for Norton 360 they plan to release an update to Norton 360 to support Firefox 4 in early May - http://us.norton.com/support/kb/web_view.jsp?wv_type=public_web&docurl=20100720113635EN&ln=en_US
    To downgrade to Firefox 3.6 first uninstall Firefox 4, but do not select the option to "Remove my Firefox personal data". If you select that option it will delete your bookmarks, passwords and other user data.
    You can then install the latest version of Firefox 3.6 available from http://www.mozilla.com/en-US/firefox/all-older.html - it will automatically use your current bookmarks, passwords etc.
    To avoid possible problems with downgrading, I recommend going to your profile folder and deleting the following files if they exist - extensions.cache, extensions.rdf, extensions.ini, extensions.sqlite and localstore.rdf. Deleting these files will force Firefox to rebuild the list of installed extensions, checking their compatibility, and reset toolbar customizations.
    For details of how to find your profile folder see https://support.mozilla.com/kb/Profiles

  • Applet doesn't work with Windows XP - Netscape 4.x

    All - I have a Java web application which is supported for Windows 2000. Users are required to use Netscape 4.x. It uses a Swing JApplet. A plug-in is not required for Netscape, but there are some supporting JAR files installed on the client to enable the Swing components. It works fine on Windows 2K, but it breaks on Windows XP. More specifically, it throws an Exception:
    java.lang.NoClassDefFoundError: com/sun/java/swing/Japplet
    Does anybody have any thoughts as to why it works for Windows 2K but won't load the JApplet for Windows XP?
    Thanks

    Hi,
    I'm assuming that if your users must use Netscape 4x, (without the plugin), then 1) they are using the built-in version of Java (1.1.5), and 2), the Java 1.1 swingall.jar file, is placed in the user's Netscape classes directory?
    If that's true, then you probably want to make sure you are using the same version of the Java 1.1 swingall.jar on both the Windows 2000 and on the XP machines. When Sun was first working on Swing, each beta version had a different package placement for the swing classes. One version placed the classes in com.sun.java.swing, but the final version placed the classes in javax.swing.
    The JApplet you are trying to use is still referring to the package name used in that beta version of Swing. If you try to download a current version of the Java 1.1 swing runtime, for installation on your XP machines, however, the swingall.jar will not have the classes in those locations.

  • Since flash player doesn't work with 17.0 what video player plugin replaces this function.

    Flash Player is on the bad list for version 17.0 firefox. Therefor it can't be installed. I get missing plugin screen or simply nothing when I click on videos on websites. Is there another plugin that can take Flash Player's place?

    For what it is worth, I could not get videos to work on FF 17.01. I also tried re-installation and updates to get Adobe FlashPlayer plugins to work, but without success.
    '''Solution''': After I downloaded and installed RealPlayer with its plugins, my problems with videos went away.

  • Java doesn't work with Windows 7. I have newest version of Java. I click on something that requires a Java script, and nothing happens.

    I'm on a website. I click on a link, and nothing happens. In the lower corner of the browser, it says "Done" Internet Explorer works fine. Gasp!

    To test if an add-on is causing the problem try running Firefox in [[safe mode|Firefox safe mode]], that will disable all add-ons. If it works in safe mode, follow the procedure in the [[Troubleshooting extensions and themes]] article to identify the culprit.
    Another troubleshooting option is to create a new profile. Firefox stores user data in a profile, creating a new profile will show if the problem is in your profile. For details of how to do that see [http://kb.mozillazine.org/Creating_a_new_Firefox_profile_on_Windows Creating a new Firefox profile on Windows - MozillaZine Knowledge Base].
    If the new profile works, you can copy the files as shown in the "Copying files between profile folders" section of the [[Recovering important data from an old profile]] article. You will need to re-install any extensions.

  • AT-AO-10 doesn´t work with Windows 2000

    I have an AT-AO-10 board that doesn’t work with Windows 2000. I have reserved two IRQs for legacy devices (non plug and play) in BIOS. The AT-AO-10 has got assigned these IRQs, a DMA and a base address that are free, and there aren’t any hardware conflicts, but the board doesn't pass the MAX's text.
    In Windows 'Information System', the board is shown in 'Forced hardware', but I don’t know that is a problem.
    If the board is unplugged, error messages are the same.

    Hello;
    You didn't mention what version of the NI-DAQ driver you are using over there. Anyway, my suggestion to you is to uninstall the NI-DAQ driver you have installed, remove the board, reboot the machine, download and install the latest NI-DAQ version (6.9.3) from NI web site.
    Try the installation with the new driver, and if that is still not working, the best bet is to try the same installation on a different machine to double check if the hardware is not defective.

  • Lexmark scanner doesn't work with mac os x

    I have a problem with my scanner lexmark p4330. For two weeks now it doesn't work with my imac. I have the imac os x 10.7.5.
    When I try to scan, my printer displays "the all in one driver did not respond" and in Image Capture it displays "lexmark language error".
    I updated my softwares, there's one for lexmark but I can't install it and I don't know why!
    Can someone help me please?

    Mmm. Not sure what's going on. Has scanning ever worked with the OS you are currently running?
    A couple of suggestions (my last two I think as I'm running out of ideas ). I realise that your problems are only with scanning, but sometimes resetting the printing system resloves printing problems. I wonder whether it will help with the scanning issue given that Print & Scan are lumped together in System Preferences. To do it go to:
    System Preferences>Print & Scan, Control+Click or Right Click on the printer on the left and select 'reset printing system'. All printers will be deleted and need to be added again using the '+' button.
    If that doesn't help my last suggestion is to download the paid for app VueScan (which you can run in demo mode for free) to see whether it works or not. VueScan is very good and driving numerous types of scanners:

  • The Bluetooth on my 2012 Lexus doesn't work with my iPhone 5.  My old android phone worked perfectly with my car.  Even the tech guy at Lexus couldn't get it to work.  What is apple doing to fix this.

    The Bluetooth on my 2012 Lexus doesn't work with my iPhone 5.  My old android worked perfectly with my car.  Even the tech specialist at Lexus couldn't get it to work.  Lexus said that other iPhone 5s were having the same problem.  What is apple doing to fix this?

    Going to the local Apple store this morning...
    My problem is not uncommon as the board is showing signs of this happening to many others as well. That is where I found the restore and reboot information to try to solve the issue of crashing apps.
    I understand that Apple will not "give away the cow", but letting iPhone users know that the problems they are having are being addressed by Apple is a little more comforting than nothing at all. Other wise, all the apps in world are useless and even more importantly worthless, if a person has to reset/reboot/reload just to get them to work.
    IF Apple can not address the basic problems with todays iPhone apps, why should one believe that the iPhone 3.0 OS is any better? Using a PC comparison, which is better, XP or Vista. If the current iPhone OS of 2.2. what ever is not working that well (as related to down loaded apps and iTunes), will OS 3.0 be any better?
    The waste of time I refer to is in going to the apps store and downloading the apps... Again why by apps if the free version does not work?

  • Move focus between elements of browser page doesn't work with JVM 1.6.x

    Hi,
    why JVM 1.6 doesn't support accessibility?
    with JVM 1.5_10 or above it's possible to move from elements of IE browser page with tab and enter and exit from applet
    with JVM 1.6 or using plugin 1.6 this is not more possible.
    with plugin 1.6 and JVM 1.5 applet can gains focus but it doesn't release it
    with JVM 1.6 applet doesn't gain focus and all keyevents are intercepted from browser.
    to make my applet and page accessible I need to move focus between elements of browser page with tab,
    and enter and exit from applet.
    Just because my users can't use mouse but only keyboard.
    Note that FireFox doesn't work at all, even if bug seems fixed https://bugzilla.mozilla.org/show_bug.cgi?id=93149
    (you can watch a recorder right sample here on: http://www.vista.it/ing_vista_0311_video_streaming_accessibile_demo.php)
    Please advise.

    some things are so easy if some one takes place the clou. I clear all cache information in the firefox browser and all is working fine.

  • Cinema Display (clear) with DVI/ADC box doesn't work with MacBook Pro

    Cinema Display (clear) with DVI/ADC box doesn't work with MacBook Pro when plugged in with a dvi to mini dvi cable. Any ideas what to do to make it work? I lugged the 23" 2500 miles into the wilderness and I need help

    Okay, here's an update: the DVI to ADC adapter does work with the Apple displays that I have tried, but it won't work with the Formac. I have tried multiple time to contact them, but to no avail... they don't even respond to threats of posting my opinion of them, which is this:
    DON'T BUY ANYTHING FROM FORMAC! They make quality products, but their customer service is a big time joke! They won't take care of you.

  • Quicklook doesn't work with .avi files

  • Firefox command line option "-no-remote" doesn't work with profile.

    I want to run the stripped version of firefox in background with one application and another full version of firefox for normal browsing. I have created the profile for the stripped version of firefox and loading the same using command firefox -P "stripped" -no-remote/firefox -no-remote -P "stripped". But when I start the full version of firefox by launcher "firefox" than it directly loads the stripped version even used the -no-remote option with profile. So I have created launcher for firefox and used the -no-remote with default profile like "firefox -no-remote". It works when first time I click on launcher but for second click it shows the message "Firefox instance is running, or not responding. close the firefox and restart the system". I have gone through the online available documents that suggests that use the -no-remote option with profile so the default profiles works correctly. But -no-remote option doesn't work with the profile. So is there any way to launch the full version of firefox by launcher on second click on launcher?

    Yes, I used separate profiles only. But the -no-remote option doesn't work as mentioned http://kb.mozillazine.org/Opening_a_new_instance_of_Firefox_with_another_profile.
    Please find below the command what I am using
    firefox -P "stripped" -no-remote
    firefox
    If I use the above command than the new firefox window get the configuration from the stripped even if I have used the -no-remote.
    I use the -no-remote with firefox default than it works for the first time.
    I have created the launcher for firefox default. So if I click second time on launcher than it doesn't work.
    firefox -P "stripped"
    firefox -no-remote
    (But doc on link -> http://kb.mozillazine.org/Opening_a_new_instance_of_Firefox_with_another_profile) says do not use the -no-remote with default.
    Do you have any idea why this is happening?
