Problem with IE7

I have a strange problem. Under Vista x64, IE 7 (I use the 32 bit IE) has no support for Java at all. I have tried 6 update 5,6 and beta 10 build 14. I am currently running beta 10 as it is the version that works with Firefox.

Here is what I know:

1. Firefox works fine (with beta 10 build 14).
2. Have tried numerous applet tests on the Internet
3. addon is loaded (I checked the menu of addons in IE)
4. AV turned off
5 Anti-spyware turned off
6. Uninstalled/reinstalled, using the Installer cleanup in between
7. Java won't even show up in the system tray, like it does when Firefox comes up
8. It is enabled in Tools/Internet Options/Advanced/Java/Use JRE....
9. Security is set to run applets, scripting, ActiveX controls
10, Tried turning off "Protected Mode" in IE7 and that did not help
11. Turned off the "next generation plug in" in Control Panel

What can I do to get this working?

I had same problem. I had uninstalled and reinstalled Java without success. The last time I installed I downloaded the offline installer. When it completed I found in the IE 7 addon manager the entry: Java(TM) SE Runtime Environment 6 Update 7. But the thing still would not work. At that point I clicked the two reset buttons on the Advanced tab. Then I went to the addon manager deleted the Java Console entry and the Helper class entry, leaving just the 'Java(TM)...6 Update 7' entry. Then I restarted the browser and went to the test webpage. It worked on my computer, under an admin account. I'm about to give it the smoke test under a non admin account.

Make sure 'Enable memory protection to help mitigate online attacks' in the advanced menu is unchecked. Checking it forces Java to run in the web start mode (source of that blank window). Howewver, applets don't necessarily run in web start correctly.

I have the exact same problem on Vista x64. I too get the blank window popping up and:

unexpectedly couldn't get the ClassLoaderInfo for the codebase/cache key

This is with IE7 32-bit, and the 32-bit version of Java. I've tried everything possible except the sledgehammer 'reset all' advanced setting.

I de-installed and re-installed, even with Update 7 and still broken.

I'm also pretty shocked that we should be DISabling the memory protection feature. This is a huge security issue. By default IE 8 has this enabled. If Sun can't make apps work properly with the memory protection feature enabled, I won't be using any sites/apps that break because of it. I'm not reducing my security settings for poorly written or coded software.

I am having the same problem and after many hours of troubleshooting I found out that if I run IE7 as an administrator then everything works fine. I also created another account in Vista Home Edition and that administrator account works with no problems.

The plugin works fine in firefox so I just dont know wherre to go next. Any advise would be apprreciated.

OK here is some more info, I looked more carefully and one thing I said was wrong - the JRE is NOT loaded! Other Sun addons are. I decided to try disabling all components but Sun ones, and it still fails. But the loaded ones are

Java PLatform SE binary
JQSIEStartDetectorImpl Class
Plug-In 2 SSV Helper
Java Plug-In SSV Helper

If I "show" Add-ons that have been used by IE, I see a Java PlugIn 1.6.0-6 (or -5, or -10, depending on which one is installed).

Any ideas why it is not loading, how to force the load, review an error message about it, etc.?

Please confirm that you are running 32-bit JRE (6u05, 6u06), and not 64 bit? Mention the download/install url?

Does 6u05/6u06 works fine with Firefox browser? BTW, what is the Firefox version? Do you see/get a particular error message when trying to run a Java applet/application? Please mention in detail and attach a screenshot if possible.

[b]Please note[/b] - [i]On a 64 bit system , public JRE installed with the 32-bit JRE is not registered. You must set the PATH environment variable to point to JAVA_HOME \bin to register the JRE.[/i]

Also read the browser footnotes at:

I am running the 32 bit version. Task list processes list showed x32 next to the name. I also show the About box on the attached jpg, which shows:

1. The simple applet screen that does not work, yet javascript does.
2. The unknown window with the Java icon in it, that does not show up in the apps list.
3. You can see in the sys tray that the JRE icon started up.

Some other notes to consider:

This guy is having the exact same problem:
http://forum.java.sun.com/thread.jspa?threadID=5281599

I get this error in the Java Console:
ERROR: unexpectedly couldn't get the ClassLoaderInfo for the codebase/cache key

As a lark I went back and installed Java 6 update 2, and the exact same thing happens. IMHO I think this is some sort of security problem with Vista SP 1.

Firefox crashes with 6u5 and 6u6. It runs fine with 6u10 beta, but IE7 does nothing with that version - it's like Java doesn't even exist on the machine (now JRE in sys tray, etc.)

To affirm, I am doing nothing with 64 bit as far as apps - Java, Firefox, and IE7 are all 32 bit. The only 64 bit is the OS.

Thanks for your help!

Is there any way I can do further diagnostics for you?

Most likely this is an issue associated with IE7 settings/add-ons etc. I tested JRE installation with versions 6u06 and 6u10 according to your configuration/instructions and everything worked as it should.

Here, as a possible workaround I propose 3 steps action-
[b]1) Reset web settings for IE7[/b] - Tools -> Internet Options -> Advanced -> Reset (Reset Internet Explorer Settings)
Note: Above will disable toolbars and add-ons including deleting of browsing history and cookies

Now as a next step -
[b]2) Uninstall any/all traces of JRE from your system:[/b] Detailed instructions can be had from:
http://java.com/en/download/help/5000010800.xml

[b]3) Install 6u06:[/b] Once you are sure that JRE is completely removed, download and reinstall latest stable version 6u06 from:
http://java.sun.com/javase/downloads/index.jsp

Now, run this testvm applet from:
http://www.java.com/en/download/help/testvm.xml

Please confirm back if this worked.

I tried EXACTLY this (a couple of things I can note for clarification), but it did not work! Java 6u6 SE appears in the system tray, I verified in the task list it is the 32 bit because it shows *32 next to javaw, but nothing happens on the link you specified and I got that blank window again. What is that blank windw that shows up in the attachment I posted a few messages higher?

Some notes:
1. I did the reset exactly.
2. I uninstalled 6u6 and 6u10 beta which were both tested. Uninstalls went fine. I did run the Uninstall cleanup utility just in case, and no Java showed up. I checked in Program Files and Program Files x86 and there were no Java folders.
3. I installed 6u6 only. I turned off Spybot prior so it wouldn't inquire about changes to registry (which I always accepted). When IE 7 started, it asked me if I wanted Pfishing turned on, I said Yes. Tools/Internet Options/Java shows "Use JRE 1.6_06 for (requires restart)" as checked.

I turned off automatic Pfishing checking and the same results occur.

What is that blank Java window that shows up??

I posted a screen shot in the 4th post in this thread. Can anyone PLEASE respond as to what the extra blank window is? I have to believe that's a big clue why this is not working. Instead of an active applet, I get this blank windows with a Sun "coffee cup" logo in the top left corner. Nothing shows in task bar.

I think this is a clue if someone could look at it and tell em what it is or why it is there...It happens from every version back to 5.0 update 9 (I just tried it) to 6u6.

I still get the error with the window coming up, and I still get this error if the Java Console is up:

ERROR: unexpectedly couldn't get the ClassLoaderInfo for the codebase/cache key

Why can't anyone say what the window is, or what the error message means?

If there is some advice that can be passed on, please let me know as soon as you can. My management sees the lack of progress on this and a Java solution is quickly becoming something they feel is not well supported. Thanks.

There is a bug posted on this issue:
http://bugs.sun.com/view_bug.do?bug_id=6694620

Can you tell as well what is the result of running this testvm applet from:
http://www.java.com/en/download/help/testvm.xml

Please feel free to update the same (bug) with any suitable/useful information you would like to add. At the same time you can submit your responses to:
jre-install-feedback@sun.com

Updated the testvm applet link. Please try the same and let me know the output

Thanks for the bug report.

I am not sure what question you are asking me as the link below it is the same bug report page:
"Can you tell as well what is the result of running this testvm applet from"

FYI, this bug occurs as well on JRE 1.6 update 10 build 22, and 1.7.0-ea. I'll update that in the bug report.

Hi donawalt,

Could you please try to uninstall both Spybot and Java, and then install only Java?

According to the error you saw at java console, it seems that you are using the old Plug-In. And, the applet seems to fail very early when Plug-In was trying to get the codebase of the applet. There's a chance the JavaScript engine from IE is not working.

I'm not familiar with Spybot, but I suspect there might be something blocking or interrupting the JavaScript process, and Spybot could be one of those. Also, are you able to reproduce this issue on other machines?

Regards,
Roger Y.
