Java does not work on my Win 7 IBM-compatible PC using Firefox as my web browser

A typical example of a website I would like to access & view is "www'cut-the-knot.org", a relatively mathematics-related website with a lot a very nice math content, where (roughly estimating) 70-90% of all web pages on the web site use Java applets to communicate that math content.
I CANNOT view the Java applets (am restricted/prevented from doing so) --- on CTK or ANY other website!.
I could go into all the details but, essentially, I have tried just about everything I can think of (or have found to do/try in discussions on the Internet by googling the problem) & nothing seems to have had any positive affect ... I can still not view ANY Java applets on ANY website! :-(
I USED to be able to view Java content on the PC I was working on, although, a few months ago, I migrated from Win XP to Win 7 when MS stopped supported Win XP. I don't know when things changed but, "while I wasn't looking" (&/or paying attention) something DID change. :-(
I'm using an IBM-compatble PC (not a Mac) with Windows 7 & Firefox as my web-browser.
I'm just a private individual ... just a "little guy" in my home ... little personal technical knowledge, no big biz connections, no $ to hire expensive (or inexpensive) experts to come in & assess & fix the problem. I would even just like to know if there is some kind of future expected date when something MIGHT get improved, barring an action "solution" of the problem.
From what I read on the Internet, some problem(s) relating to this issue has/have been extant for at least two years, dating back to at least 2012, if not further? I assume the problem would have been fixed long ago if it were easy to fix so, I'm not trying to be overly critical ... just asking for some kind of status report --- help/communication/knowledge/expertise/solution/etc ... & any information would be appreciated. Knowing WHAT the problem is is a high priority to me, certainly as well as understanding HOW TO FIX the problem, & WHEN that fix will occur.
Java is a seemingly wonderful technology but, if there are such severe security risks that require it be enabled so that no one (I'll assume I'm not the only one unable to view Java applets) can use it, it doesn't have much value to visitors to websites that employ Java to deliver a majority of their content. Part of the problem, obviously, is that (like CTK) MANY websites ALREADY use/employ Java --- & therefore, end-users have almost no access to the content in/on those websites.
Thanx in advance ...

Java does not work at all upon using the update manager to update to firefox 3.6.10 for Ubuntu 9.0.4

OS: Ubuntu 9.0.4
Browser: Firefox 3.6.10
upon updating to firefox 3.6.10, java does not work at all.
websites that use java do not work at all anymore, when they worked just fine before the updating thru update manager. e.g. hulu website cannot play any of the shows.
i can give the folder of bookmarked pages i tried.
how to do that on here, i've yet to see if possible.
i can even give saved text from the terminal concerning certain attempts.
when i updated thru update manager, it gave some weird java plugin that wasn't there before "The IcedTea Web Browser Plugin IcedTea6 Java Web Browser Plugin (execution of applets on webpages)".
i uninstalled this as instructed by an answer found in one of the pages i saved, cuz it was conflicting w/another java program the updater said i needed. right now, i don't remember for sure what it was. it perhaps was realplayer flash or Java itself. w/all the hours/days of searching i put in, it's difficult if not downright impossible for me to remember all the specifics of what i tried.
i've searched throughout many webpages (including many searches on mozilla, ubuntu, java, etc) for instruction in fixing the problem.
oh, and incidentally, on the Java site, when i try the verify test of Java, firefox pops up with that yellow bar right below the slew of tabbed website windows, giving the statement "additional plugins are required to display all the media on this page. (w/link to) install missing plugins ." which is what i do, go thru the requesting plugin installation. it comes up with, guess what, the IcedTea Java Plugin. i click on the 'next' in the "Plugin Finder Service" box that pops up, & all it gives me is "No plugins were installed. IcedTea ...Plugin failed. and the link 'find out more about plugins or manually find missing plugins'". the link takes me to some of the very things/plugins that wouldn't install in the first place. the Java test failure is a LOL funny, as what plugin it is saying is required (IcedTea) is a recommended alternate program to display the very test in the first place.
i followed the given instructions on those many searched pages, in every case (barring what i may have just plain missed), but to no avail.
i've even gone to the point of trying to reinstall the previous 3.5.13 firefox version, from mozilla site. even that wouldn't install.
i've tried installing Java for my sys direct from it's site. nada.
now it's time for me to post the problem & perhaps someone will come up with some kind of "dummy" way to fix it.
until then many sites a regularly use are totally useless to me on this fast puter.
the only way i can get to use such sites, are two choices: 1. use a dinosaur laptop, which is slower than molasses & cannot handle to any streaming stuff, or 2. use an available internet access puter at the library. but useage for ea person per day is limited to only one hour a day. and one can end up waiting for an hour or more ( in the busiest periods) to even get to use one.
so, is there anyone at all, who knows any for-sure working fix for this problem?
thanks muchly :^D
p.s. i can't pay anybody any money for such help, as is required in certain sites (e.g. Java website), cuz i don't have any.
i can pay in labor tho, if there is someway to find someone who can physically be at this puter w/me, taking me step-by-step
sorry for the 20-pg essay. i hope it was all clearly understood. if, not, well, clear communication is always what is needed, ask away.

Your above posted system details show outdated plugin(s) with known security and stability risks.

Update the [[Managing the Flash plugin|Flash]] plugin to the latest version.

Back up all data.
Quit Safari. In the Finder, select Go ▹ Go to Folder... from the menu bar, or press the key combination shift-command-G. Copy the line of text below into the box that opens, and press return:
/Library/Internet Plug-ins
From the folder that opens, remove any items that have the letters “PDF” in the name. You may be prompted for your login password. Then launch Safari and test.
If you still have the issue, repeat with this line:

i use firefox as my internet browser. when i go to itunes to download music it says i am not connected to the internet when actualy i am. what am i doing wrong?

Firefox is a web browser not a homepage.
It sounds like you you have the old www.google.com/firefox/ start page that used to be the default homepage in Firefox before Firefox 4.0 sometime. It is not being maintained by Google anymore so either ignore the message or while in Firefox go to Tools->Options->General->Homepage section and change your homepage.

C execve of $JAVA_HOME/jre/bin/java does not work

I have a static executable (I don't want to link shared libraries for security reasons) which ultimately tries to execve the java executable in the JRE (Linux). Unfortunately I'm getting the following errors:
Error: could not find libjava.so
Error: could not find Java 2 Runtime Environment.
I've seen mention of these errors in other posts and have tried everything I can find (add stuff to PATH, CLASSPATH, LD_LIBRARY_PATH, JAVA_HOME, and more). Everything I've tried does not seem to do a lick of good. The execve function constructs an explicit environment, so I'm wondering if there is something basic that java needs in the environment that is inherited normally in a shell. I'm at a complete loss here. Any help would be appreciated. A very simple C program to reproduce this is pasted bellow.
#include <unistd.h>
void main(void)
char * arg[2];
char * env[10];
int i;
i=0;
arg[i++] = "-version";
arg[i] = NULL;
i=0;
//add any environment variables to env like...
//env[i++] = "LD_LIBRARY_PATH=<java_path>/jre/lib/i386/libjava.so";
env[i] = NULL;
execve("/usr/local/j2sdk_nb/j2sdk1.4.2/jre/bin/java", arg, env);
}

It fails because you do not set argv[0] to the path of the program you're calling.
Try:
#include <unistd.h>
int main()
char * arg[3];
char * env[10];
int i;
i=0;
// This is the big deal:
arg[i++] = "/usr/java/j2re1.4.2_02/bin/java";
arg[i++] = "-version";
arg[i++] = NULL;
i=0;
env[i++] = NULL;
execve("/usr/java/j2re1.4.2_02/bin/java", arg, env);
}

Custom URL Handler in Java does not work for JavaFX

Hi,
for the purpose of playing Media Files that are decrypted on the fly and then hold in memory with the JavaFX MediaPlayer we are trying to register a custom URL Handler. The thought behind that would be that with the handler JavaFX should be able to open a stream and play back the file (a bit like jar://). In a testcase isolated from JavaFX my handler including registration at JVM is working fine, but once i plug it into JavaFX it stops to do so. I'm calling the Media(String) constructor. It fails with "Unsupported scheme". It seems like that JavaFX is not relying on the JVM URLStreamFactory but rather implementing a separate mechanism to figure out which handler it should use thus failing in my use case.
Is this expected behavior and if so can anybody suggest a work around?
EDIT: Actually read the Javadoc for Media. It explicitly says that it only supports File, HTTP and Jar. So it is expected behavior however I am still open for suggestions on this.
cheers,
andreas

I believe that the connection details are stored as part of the CR itself. Therefore if you update a connection in the CMC that might not change the parameters and credentials, especially when using sub-reports.
Hope this helps...

Flash does not work correctly in full screen after most recent Firefox update

== Issue
==
Firefox is having problems with certain web sites
== Description
==
Yesterday, firefox updated itself automatically. The "what's new" screen suggested that I update Flash immediately, so I did. I had a little trouble. I eventually uninstalled Flash and re-installed with the latest version, but it is now up to date. Now flash videos will not play properly in full screen. The picture will freeze for a few seconds with the audio still playing, the screen will go blank, then the video will restart from where the audio was when the screen went blank. Sometimes Flash will crash completely and I will have to reload the page to restart the video, even not full screen. Other times I get an error message that my video driver stopped working. I have checked and my video driver is up to date.

I updated to 3.6.4 and when I went to NetFlix to watch the next show of a series, it said
something like
Installation complete, restart your browser.
I restarted browser, same problem. Restarted comp. Same problem.
I updated Adobe Flash 10.1, still same problem.
But able to watch some vids on other sites, but full screen gave me the big blank white screen with audio only, had to click around in the dark ( so to speak) to find the minimize button.
I did a System Restore to before the Firefox and Adobe updates.
I then did not update Firefox as recommended and went to NetFlix and wellah, i can view the movies again.
And Full Screen is fine.
I then experimented and updated Firefox only, went to NetFlix and got same msg with no viewable shows.
So did a System Restore once more.
Staying at 3.6.3 for a while longer until I know I can watch my movies.
I don't own a TV, so this is my only form of an occasional escape.
I do hope this is figured out soon.
With what I have done, it seems to be Firefox, Not Flash.
Good Luck to us all.

Firefox does not allow me to 'paste' url's/rapidshare links anywhere on the web browser.

I noticed this problem when I purchased a Rapidshare account. In Google i found the URL of a movie>highlight the link>copy>but the 'paste' option is blanked out (not available) when i come to paste the link in the web browser. I have tried ctrl-v and also the edit>paste but the 'paste' icon i always 'greyed' or blanked out. This problem does not occur on any other computer in the house, just on my laptop. It only occurs with rapidshare links (and similar URL's). I can not paste in the web browser nor can I paste on the rapidshare website because the paste option is not 'click-able'. I don't know what do to, please help.
== This happened ==
Every time Firefox opened
== I just signed up to rapidshare and have the 'paste' option has never worked.

Java does not work

I have installed the java runtime environment and then when i went into addons it was not there. I have tried installing from file but it says it could not install because the file was corrupt. I am running puppy linux.

Which Java version did you try to install (Java 6 or Java 7)?
The rpm version or the tar.gz (or bin) version for Linux?
If the rpm doesn't work then you can try the tar.gz archive and copy the files to a java folder in /usr/local<br />
You will have to create a symlink to the Java plugin (lib/i386/libnpjp2.so) in a location that Firefox scans for plugins.

Generate Java does not work

I am using Jdeveloper 10.1.3.0.4. No files are generated when I use the generate Java command.
Basically I open a database connection, highlight a PL/SQL procedure and right mouse, select Generate Java, select OK to the dialogue box. When I check for the genrated files nothing has been generated.
Can anyone help?

Fixed this by running sqljutl.sql .

Need Java for online course. Java does not work with Mavericks or times out quickly?

After upgrading to Mavericks 10.9.3 I am unable to connect to Blackboard through Java for my online courses. Research shows compatability issues. Same issue also occurs with my two Mac Air. is there a solution without taking down firewall and allow all applications?

You might be able to add the website to the list of excepted sites on the Java System preference.
You might be able to setup a proxy connection to your server that Java can speak over.
