JAVA version 7 update 5 build 1.7.0_5-b06 and Firefox 14.0.1

I recently updated firefox, then had to update Adobe and Java. This seem to lead to problems with Vuze, which I unistalled and reinstalled but have not been able to get to work.

I have uninstalled and reinstalled Java 7 but have not been able to confirm it is working at the Java.com test page. I have read over Problem with Firefox 14.0.1 and Java https://support.mozilla.org/en-US/questions/932761

Used these 2 Java sites; http://www.java.com/en/download/installed.jsp http://www.java.com/en/download/testjava.jsp

But have not been able to get any answer in the Java tests

Any help would be appreciated.

1) troubleshooting JAVA tests and installation. 2) How to confirm it's not a firewall issue. If so what is the name of the java files i should allow through.

So the problem is that Vuze is not working correctly? Or that the Vuze toolbar is not working correctly? Or that sites which require the Java runtime are not working correctly? Or all three?

I have attached a screenshot of the testjava page. The applet takes about 20 seconds to load on a 5-year-old laptop. Is your display similar?

Please note that Java is not used much on the web these days. If you see any errors involving JavaScript, that is interpreted natively by Firefox and does not use the Java runtime.

Hi, thank you for responding so quickly.

JAVA: I have not been able to get the Test to run to conclusion. I have let it run for 5 minutes and no results, then it fails and an error exists. Been trying to get it to work to see if there is a Java, Firefox, or Firewall problem.

As for Vuze I have not gotten that program to work since I updated it yesterday, and even after a complete reinstall. I am trying to eliminate Java as the source of Vuze software problems. I will pursue this on the Vuze forum.

I am mostly concerned that I couldn't get the Java test to run and work on Firefox. (Just tried it on IE and couldn't get the Java test to work either). I don't know how serious this is, or if I should not bother worrying about it.

Thanks, Richard.

Where are you seeing this version number: 1.7.0_5-b06 ?

Edit: I think I see it now: Windows Control Panel > Java (32-bit)

Can you check the below as well?


When I open the about:plugins page (type or paste that into the address bar and press Enter) I get this:


Java(TM) Platform SE 7 U5
   File: npjp2.dll
   Version: 10.5.1.255
   Next Generation Java Plug-in 10.5.1 for Mozilla browsers

You can try http://www.java.com/en/download/manual.jsp for the latest version (see screen shot).


The Plugin Check page (http://www.mozilla.org/en-US/plugincheck/) shows:


Java(TM) Platform SE 7 U5 Next Generation Java Plug-in 10.5.1 for Mozilla browsers 1.7.0.5

Well according to my Firefox Check Plugins my Java is uptodate (Big Green Button with thumbs up)

INFO Java(TM) Platform SE 7 U5 Next Generation Java Plug-in 10.5.0 for Mozilla browsers 1.7.0.5

I checked About:plugins

Java(TM) Platform SE 7 U5

   File: npjp2.dll
   Version: 10.5.0.6
   Next Generation Java Plug-in 10.5.0 for Mozilla browsers


So I can see a discrepancy between my 10.5.0 and your 10.5.1 And I have no Idea why since I just finished deleting and installing the most recent version from Java.com

I have decided that Java must be working. I just updated to Java 10.6 and seems to be working. Though i'm unable to test properly. I will just wait till something comes up.

All the problems I have been having with Firefox seemed to relate to my Flash Player, which I have completely uninstalled. Now Firefox is working fine, a little slow, but no bugs yet.

I will have to browse to find a solution to Flash Player plugin.

Install Flash 10.3

JAVA FRUSTRATIONS

Java Application Error General Exception "ClassNotFoundException: CrosswordLoader.class"

From trying; http://www.thestar.com/games/crossword and clicking on Todays Crossowrd

Are Java and Flash connected (I have disabled my uptodate Flash because of problems)

Rich

ps I just tried to verify through Java that Java was working, correctly installed and recieved this error

Ignored Exceptions: java.lang.ClassNotFoundException: jreVerification.class

Is there a problem inside my java settings?

Again any help would be appreciated. Thanks.

I have been reading Firefox help files and they discuss Java plugins, and missing plugins. Even though my java plugin in enabled it does not appear to be at this location?

C:\Program Files\Mozilla Firefox\plugins

What should it be called? And if it is missing where can i find it?

Any help would be appreciated. Thank you all.

Dear ideato

I checked to see if java was working at Java.com per your link and got this error message;

Ignored Exception: java.lang.ClassNotFoundException: testJava2_1.TestVMApplet.class

more options

Check, anti-virus and firewall programs if blocked java from there. Disable anti-virus and firewall to see if this solve the issue, if yes create an exception.

Thanks for the idea Ideato;

I have already thought of that, and believe that should not be the problem. I have added JAVA to my list of programs to allow through the firewall. I have F-Secure anti-virus.

But I will check that out again. One problem is that from the list of JAVA programs i'm not sure which ones I should make an exception for?

Just Brilliant!

New Java flaw could hit 1 billion users

A new Java vulnerability has surfaced that apparently affects all Java runtimes and therefore puts close to a billion users at risk.

Security research company Security Explorations has issued a description of a new critical security flaw in Java SE 5 build 1.5.0_22-b03, Java SE 6 build 1.6.0_35-b10, and the latest Java SE 7 build 1.7.0_07-b10. This error is caused by a discrepancy with how the Java virtual machine handles defined data types (a type-safety error) and in doing so violates a fundamental security constraint in the Java runtime, allowing a complete bypass of the Java sandbox.
