Next generation java plugin - How to toggle as non admin

We have several users that have to access some timekeeping and bookkeeping sites that use the java plugin. However, one of these sites requires us to disable the next generation plugin and the rest of them require us to enable it. What I'm looking for is a way to grant our users permission to toggle the plugin without granting them administrator rights to the whole computer. These systems are all running Windows 7 x64, and Java 6 update 31 (32 bit, and this particular version due to compatibility issues with these sites) Can anybody suggest a way to do this?

Done Thanks!!

Next Generation Java Plugin issues with Applets

Hi,
We have an web application with a jsp page which launches different apps in seperate browsers.
The jsp page has
<jsp:plugin type="applet"
                            code="AppLauncherApplet"
                            height="0" codebase="../../jars/" width="0"
                            name="LaunchApplet"
                            align="bottom">
                        <jsp:params>
                                <jsp:param name="applicationURL"
                                           value="applicationURL"/>
                        </jsp:params>
                        <jsp:fallback>
                                <p>This feature should run on applet supported
                                   browser.</p>
                        </jsp:fallback>
                </jsp:plugin>And applet has
           init()
          String appURL = getParameter("applicationURL");
          if(appURL != null && appURL.length() > 0)
               String WIN_PROGRAMFILES = System.getenv("programfiles");
               String FILE_SEPARATOR   = System.getProperty("file.separator");
               String execUrl = WIN_PROGRAMFILES + FILE_SEPARATOR + "Internet Explorer" + FILE_SEPARATOR + "iexplore.exe "+ appURL;
               System.out.println(execUrl);
               Runtime.getRuntime().exec(execUrl);
               System.out.println("Opening New IE Instance...");
            }Basically this is a launcher app...
This works fine when we run on JRE-build 1.6.0_21-rev-b08and launches apps in seperate browser windows as we click on links...
But after i disable Disable next-generation Java Plug-in as explained in http://www.java.com/en/download/help/new_plugin.xml
Then i noticed weird behavior that apps are getting opened in multiple windows per click.
For example... if i click on a link to open that app in a new browser... 3 seperate browsers are launched.... where it is expected to launch 1 seperate browser window....
I noticed applets init method got called 3 times... means applet initialised 3 times...
I am wondering if it is a JRE issue?
JRE-build 1.6.0_21-rev-b08
Please advice....
Thanks,
Murali

Disable next-generation Java Plug-in-Is Applets load on same JVM guranteed?

Dear all,
I am working on a banking application that uses WinXP and JRE1.5, where the banking application is browser based and with a lot of applets. For inter-applet communcation, we use singleton, a Object called CommonFunctionUtility, which is a single instance so that all applets can share information.
Recently, there is a direction to upgrade the JRE to 1.7. However, after upgrade, we find that applets are loaded to different JVMs so that they're not referring to the same instance of this CommonFunctionUtility, so applet hangs as they cannot retrieve correct information.
As an interim solution to meet internal requirement to complete JRE1.7 rollout, it is suggested to disable the next-generation java plugin first, and amend the application later using other way to share data later. In view to this, may anyone have any idea that Oracle ever confirm that after disabling next-generation java plugin, it is guranteed that all applets in same browser will be loaded on same JVM?
Regards,
Francis

By disabling the next generation plugin it should "work as before". That's about as much guarantee as you'll get, the business of providing guarantees lies on your shoulders (without an Oracle service agreement) through system integration tests.

Next-Generation Java 7 Plugin Performance on Windows 7 and IE 8

Applet performance has historically been a black eye, to say the least, for Java Applets. Slow load times over today's networks are simply not tolerated by today's network standards. I'm currently supporting an Applet that is forced to move to the Java 7 Platform. As such, we are particularly sensitive to anything new that may further hinder applet performance. To that end, I've been doing quite a bit of benchmarking lately of Applet load times using various configurations with the Java 7 Plugin on Windows 7 using IE 8.
To capture Java Applet load times, I've simply been marking the start time in Javascript from the HTML onLoad() event, and then calling out to a similar Javascript function to mark the end time from the bottom of the init() method in the Java Applet. I subtract the two times to get a general idea of how long it takes to load the applet.
The best load times, so far, (when loading the JARs from the web server) occur when caching is employed (e.g., cache_option, cache_archive, cache_version). What I've noticed though, is that when everything else is the same, the performance is degraded by at least half when I check the 'Enable the next-generation Java Plug-in' in the Plugin Control Panel. Applet load times slow down by at least half when this option is enabled. When loading JAR files from the web server, with caching in effect, the applet load time performance is comparable to loading JAR files from the file system only when the next-generation plugin is not enabled. I assume this is because of the associated overhead of spinning-up this external JVM process, but I'm not certain.
Does anyone know if this is a correct assumption? And if I'm correct, are there ways to speed up the loading of an applet when caching is used with the next-generation plugin? Is this another cold-start vs. warm-start issue for the JVM?
My goal is to have applet load times for JARs loaded from the web server, using the next-generation plugin, as fast as when the JARs could be loaded from the local file system (which apparently is no longer possible using the next-generation plugin, sadly).
Thanks!

Thanks Igor.

Java Applet is in O&M phase and been around a while. Rich Internet Application with file system access requirements. Currently compiled with JDK 1.5. 10 JAR files total, 6 of which are third-party JARs. 4 JARs are custom and are signed.

                    1.0.0.11"/>
<PARAM name="type" value="application/x-java-applet"/>
</object>
Here's a brief synopsis of my test methodology:
Assuming caching is the fastest performance I'm going to get by putting JARs on web server, goal was to determine if browser plugin and next-gen plugin will offer the same performance in terms of time to load the Applet.
To test, I unchecked the 'Enable Next-Gen' plugin option in the Java Plugin. I updated the cache_version values for all JARs. I 'touched' all JAR files in the WAR (I use cygwin) and redeployed the WAR. I have a cli script that launches IE and points it at my applet. When the applet loads, a Javascript Alert box displays showing the number of milliseconds it took to load the applet. I document the time, quit the browser, and re-execute my script. I do this 10 times for each test scenario and take the average.
The two basic test scenarios are using the Browser Plugin (not next-gen) and using the Next-Gen Plugin. That is the only variable I change between test scenarios. Here is the raw data I collected for each test scenario:
Not Using Next-Gen Plugin (milliseconds):
run1 run2 run3 run4 run5 run6 run7 run8 run9 run10
1761 474 535 495 500 505 502 267 693 513
Avg: 625ms
Using Next-Generation Plugin (milliseconds):
run1 run2 run3 run4 run5 run6 run7 run8 run9 run10
5382 1529 983 1545 1622 1575 1544 1544 1545 1529
Avg: 1880ms
The time it takes to load for each first run indicates caching is happening as subsequent runs are faster. I verified that the JVM is not making http requests for cached JAR files by proxying these requests with Tcpmon just to confirm this was the case.
I'm basically just looking for a logical explanation to account for the significant time difference that occurs from this Plugin configuration change. It seems to make logical sense to me that this can be explained by JVM Process start up time, but I'm looking for corroboration on that or another explanation.
Thanks for any advice, help, etc. I'll start looking into JNLP and JAR index as well.

How to disable Next Generation Java Plug-in for GPO software deployments?

Is there a way to disable the Next Generation Java Plug-in using a script or batch file for GPO software deployments?
Our group needs to deploy JRE 6 Update 20 to a large number of Oracle Financials users. As part of this deployment, we need to disable the Next Generation Java Plug-in as part of the installation for each desktop. Our plan is to extract the MSI installer package from Sun and create a GPO for software deployment.
It seems you cannot disable the Next Generation Java Plug-in using a simple registry hack or customized MST transform file. Is there another method for disabling Next Generation Java Plug-in?

btenney,
Thanks very much for your suggestion. Can you explain what the parameters are on the ssvagent.exe that you noted -high -jpisetup -old? I can't seem to find any information on the parameters. Also, will this set the configuration just for the user logged on (current user) OR for all users existing and future?
We are having trouble getting next-gen java shut off for all possible users that may logon to a machine in future .. thus looking at putting in bootup login script, but hoping there is a better way to have it take affect at the machine level. Or to at least automate at the user level (existing and future windows users/profiles)

How to reload proxy configuration with Next Generation Java Plug-in

When using the Next Generation Java Plug-in, I no longer see an option in the console to reload the proxy from the browser by pressing p. If the proxy information is changed in the browser after the Java console loads, is there a way to reload the proxy from the browser? If not, why was it removed?
It's been useful to us because of the way we test with LoadRunner, which uses a proxy. Our other options are to either disable the Next Generation Java Plug-in so the option comes back, or set the proxy in the Java settings instead of trying to read from the browser, but I'm trying to find out it's one of those will be necessary.
We're using Java 1.6.0_17. Thanks!

Next Generation Java Plug-in

Hi -
Our desktop application was built using older versions of core java and now runs on 1.6.0_19. When the next generation java plug-in came into play (enabled by default) we started having some GUI issues with various dialog boxes (freezing, not functioning properly, etc). These could probably have been written better whenever they were. We can individually go back and fix all of these but don't have the time to do it now. So we decided to uncheck the plug-in for now. When I do this locally on my pc, everything works fine. However, our application is available on citrix servers and when I disabled the plug-in there, I'm getting "Java Heap Space" exceptions. I definitely know there is sufficient memory on the box and the JRE settings are fine as well. Any idea why disabling the plug-in would cause java to run out of memory? I have been really confused by this and any insight would be greatly appreciated.

anyone?

The next-generation Java Plug-in

I really need to disable the next-generation Java Plug-in on the Advanced tab of the Java control Panel, but it is grayed out. I have admin rights. I tried to uninstall/install Java, but that did not work. Any suggestions? Thank you

Java 8, next-generation java plug-in?

hey all,
i'm looking for the "enable the next-generation java plug-in" option in java 8 update 40, but can't find it in the advanced tab of the java control panel.
has it been removed?
thanks!

anyone?

Java options: "Enable the next-generation Java Plug-in"

On windows, this option is sometimes "grayed out" and you cannot disable it.
This option is available since java 6 u 10, and is accessible via windows control panel, or alternatively via javacpl.exe.
Which are the cases where the option is grayed out?
I've made the assumption that it is grayed out on windows 7, or on windows 7 64, but there are cases of windows 7 64 where the option isn't grayed out.
It seem neither connected with Internet Explorer version, since it works or not with either IE 8 or IE 9.

Current Firefox versions (3.6 and later) can only run Java applets via the Next Generation plugin.

hey all,
hope I have the right forum for this question.
I'm deploying Java 7 update 55 to users in our company and have discovered that we need to disable the next generation plug-in.
is there a way to deploy Java with the plug-in disabled? preferably a command that I can add to a batch file.
I've read about a registry hack (doesn't work based on feedback), but I'd prefer not to deploy a mass registry change company-wide.
any help would be greatly appreciated.

Firefox keeps prompting users to disable java plugins How can reinable them through the command line or registry?

Windows users keep getting prompted about java version being insecure and are advised to disable the plugin. They then complain that java based websites no longer work. Can I disable / prevent this warning feature. And can I re-enable java plugin via command line or script? I need to do this on a large scale and various versions of firefox. Right now I will need to abandon firefox if I cannot easily resolve this. Yes I realize updating to latest version of java is a solution... but this will take too much time now and how long before another security fix for java and then I will have to update yet again.

Tylerdowner, to say that Firefox 3.6 is no longer supported is not an answer. Apparently, the so-called block deployed for the Mac OS X version of Firefox, created to deal with a vulnerability in Oracle's Java, has now crept into the Windows version. Moreover, it is blocking the latest version of Java, which was not intended according to https://bugzilla.mozilla.org/show_bug.cgi?id=741592. The official text of the block follows:
Java Plugin has been blocked for your protection.
Why was it blocked?
Outdated versions of the Java plugin are vulnerable to an actively exploited security issue. All Mac OS X users are strongly encouraged to update their Java plugin through Software Update, or disable it if no alternatives are available. For more information, please read our blog post or Oracle's Advisory.
Who is affected?
All Firefox users who have installed the Java plugin, JRE versions below 1.6.0_31 or between 1.7.0 and 1.7.0_2.
What does this mean?
Users are strongly encouraged to disable the problematic add-on or plugin, but may choose to continue using it if they accept the risks described.
When Mozilla becomes aware of add-ons, plugins, or other third-party software that seriously compromises Firefox security, stability, or performance and meets certain criteria, the software may be blocked from general use. For more information, please read this support article.
Well, whoever wrote the code to block the Java plug-ins specified above screwed up, since it is blocking even the updated Java plug-in.
I have an enterprise with many computers, and we had deployed Firefox as our browsing platform. Based on the latest decisions at Mozilla, new version numbering, forced release cycle, and almost all add-on vendors just walking away from the maintainence nightmare created by this decision, I guess it's time to move over to the Dark Side and adopt Google Chrome.

How do I allow non-admin accounts to have access to the player?

I need help please. First I want to say that I did read the "Read this first" sequence, but I have no idea how to find out where all those posts are or how to browse for them, so PLEASE do not be cross with me if I am asking something already addressed. Here is my problem: I downloaded and installed the latest version of flashplayer according to the instructions. That gave me the flashplayer debugger and it all works like a charm on my administrator account. But as soon as I switch to a regular user account (any non admin, acct) it is as if I had not installed anything that is the videos do not get displayed instead I get a blank space, My computer Operating System is a windows 7 and I use Internet Explorer version 8. the win 7 runs both the 32 version and the 64 version of the IE8 but I never use the 64 (because I read somewhere that does not work), Thank you very much!

First thing(s) to try:
on the limited account, can you see the Flash animation at http://www.adobe.com/software/flash/about/ ?
if yes, can you right-click on the Flash object, select Settings, then disable Hardware Acceleration?
if still not working, can you check IE Tools | add-ons, if Shockwave Flash object is enabled?
If it still fails, can you try the following:
download the executable installer http://fpdownload.adobe.com/get/flashplayer/current/install_flash_player_ax.exe (save to disk)
still on the limited account, right-click on the downloaded installer, then select 'Run as Administrator')
Does it work now?

How to disable the Next Generation Java Plug-in?

How to get to use the classic plugin, that is the question. The NG plug-in was introduced in 6u10 and I have 6u14.
That is, if it's on in the first place (I have no idea).
I was told to turn it off when I complained to a company about an applet which doesn't work so well (it kind of works but is frustrating to use, animations are anything but smooth, random delays in drawing graphics and things like that), and apparently the new plugin is suspected to cause the problems (which other customers haven't reported).
Windows version of java has the option to turn it off and Sun has instructions on how to turn it off, but in Linux there is no such an option in Java Control Panel and if it's possible to do in Linux, googling and searching forums didn't really help.:(
Of course I could try downgrade, but I suspect there is no ready package for 6u9 nowhere to be found and the cvs pkgbuild I found in AUR proved to be too bitchy for me and would require more editing than simply changing version number and md5 sums.

How do I prevent non-admin users from putting Lion to sleep?

I share a MacPro at home with a few others. I use it as a server as well as keep content on it that is streamed to all sorts of devices; they use it as a mac to check e-mail. Two of the users have a really bad habit of putting it to sleep because the display wastes power being on (even though it will dim in 60 seconds and turn off in 3). Despite my best efforts to assure them that putting it to sleep will cause other things to crash once a month they go ahead and try to do it anyway. Suffice it to say they then ask me why the AppleTV has no access to the content stored on the MacPro.
With that in mind I want to know if it is possible to require an administrator password to put the Mac to sleep? 5 of 7 users do not have admin privileges, the other won't put it to sleep. If you know a wayf to prevent it - you would be my hero. If your suggestion is simply prevent them access to the Mac that won't really work - despite my hopes.
Let me know - its a huge pain every time it happens.
Thanks,
Sandy.

Hi - you have will have to change the device passwords on all the base stations and then don't give them to anyone except the administrators and tell them not to save them on their computers that use the older versions of the Airport Utility - for the newer versions like the mobile apps, as soon as you enter the pasword it is saved and is visible in the advanced pane along with the network password - so if anyone gets a hold of your iPad or iPhone, they can edit the whole network - I have this same issue with my networks in the office and it is inconvenient but doable - I hope this helps
