Java deployment

as part of a my dissertation i need to discuss how i would deploy my java system.
The system needs to run on 400ish computers and it would be stupid to just go round 1 by 1 and install java.
My question is how do you deploy java over a large network so that all machines can run java applications. How does this effect performance and stability of the machines.
If anyone can suggest a place for me to read about it or a few ways so i can wrie about them. My tutor is a c# and .net fan so i really need to show him that java is not evil and that i was right to do my work in java!
please help and thanks to those who do!

the application will be saved onto the disk space of each computer. Java Web Start ensures you have the latest copy installed and the approriate version of java installed.
When it is ran i need it to how. You can install it by opening an approriate web page or URL or shortcut.
How would i use java start web for this??This is exactly what JWS was designed to do.

Error in Java deployment step of SAP Netweaver installation

Hi Team,
We are installing SAP Netweaver 7.4 SR2.
We are using How to install SAP NetWeaver Application Server Java guide.
We have completed all steps upto step 27 without much hiccups, but during Java deploy stage, we are getting errors related to port 50004.
We have restarted the machine and continued the installation .but are still getting the error.
We have checked the heap size -- Its value is 1024mb.
Do not know what is wrong with this.
We have assigned 4 GB Ram and Paging is also set as per requirement. Previously we had used 3.5 GB RAM
Attaching the log files:
In deploy_api.0 log file we are getting lots of messages as:

Hi Suraj,
Hope you are doing good.
Nice to hear from you again. It looks like P4 connection is affected:
1)
Review note 1158626 and adjust the P4 port configuration accordingly. You will need to check whether the P4 port is available. Note 1925352 will help you to check this (you can use the sapcontrol command or others mentioned to check whether host: 172.16.35.110 and port: 50004 is available or not).
2)
Make sure that there are no invalid profile files. Kindly move the profile files that are old to some other location.
3)
Also, please verify that you don't have any non-deterministic names in the etc/hosts file, per SAP note:
1134222 - Cannot access AS Java via P4 connection
Hope this helps.
Kind Regards,
Hemanth

How do i fix the message to update java deployment kit when I already have the lastest version of java installed?

I keep getting a message that "An important update is available for Java Deployment Toolkit 7.0.400.43". I click on "Update Now" and I get taken to the Mozilla Plug-in check page. A brief message shows at the top of the page that tells me some plugins are out of date and then disappears. The plugin checks show all plugins are up to date. I have uninstalled/reinstalled Java more than once and run a registry cleaner, but once I install Java the same messages appear. I am on a Windows XP machine and I am running an older version of Firefox (9.0) because addons for some of my other software don't work with newer versions of firefox. Can I get rid of the message or do I have to live with it because I use an older version of firefox?

Please update to Firefox 23.0.1 IMMEDIATELY. Old versions are extremely vulnerable to security issues, and all your add-ons should work if they work in Firefox 10 anyway.

Removing the Java Deployment Toolkit?

Hello,
I was wondering if it is possible to remove the Deployment ToolKit .dll from the machine or disable it in browser within an infrastructure? I wanted to see if there are any other functionality that could be impacted I remove the deployJava1.dll from my machine or disable it in browser?
The link below shows the following information regarding blocking or removing.
What is the Java Deployment Toolkit?
What happens if the Java Deployment Toolkit plug-in is blocked?
By blocking the Java DT plug-in, the Java version detection mechanism is disabled. Therefore, when a user tries to launch a Java applet or application, that requires a specific Java version other than the active Java version on a user’s system, it will fail.
Does this mean the application will break? Or just that the detection mechanism will be broken for the application version check and the app will still run? I would like to remove these bits to ensure no version checking is done on my systems.
Thanks,
Michael

Your "More System Details" doesn't show any Java plugin at all. Are you sure you have the current version installed? This test page will lead you to a download if needed:
http://www.java.com/en/download/testjava.jsp
If you have Java installed, check whether its two plugins (Java Platform SE and Java Deployment Toolkit) are set to "Never Activate" on the Add-ons page. That disables them. Open the Add-ons page using either:
* Ctrl+Shift+a
* orange Firefox button (or Tools menu) > Add-ons
In the left column, click Plugins. Note that disabled plugins cluster at the bottom of the list.

Why is Java Deployment Toolkit (click-to-play) blocked, also the referenced bug is closed and there are no security issues known in Version 7 U51?

I think it is important to block unsecure addons. But if you do so there should be an open bug assigened. The referenced bug for this add-on is allready resolved so I do not know why this plugin is disabled. https://bugzilla.mozilla.org/show_bug.cgi?id=636633
I have the problem that I want to use Secure_Auth that is using the Java Deployment Kit in such a nasty way (via javascript) that firefox doesn't see that the deployment kit should be started. Therefore I will not be asked to allow this plugin always for this web site. Since there is no documentation available how to do this configuration in a config file I am stuck at the moment.
I'm a liitle bit suprised that blocking all versions (even secure versions) is a way to get a good user experience.
Regards
Martin

That's a bug report in the Blocklisting component, meaning it's a request to add an add-on to the blocklist. The fact that it's marked as fixed means the add-on has been added to the blocklist.
* https://addons.mozilla.org/firefox/blocked/p428
* [[Add-ons that cause stability or security issues are put on a blocklist]]
Given that there's no way to disable Click-to-Play for this plug-in (the only options are Ask to Activate or Never Activate), if Firefox doesn't trigger a Click-to-Play prompt, I see no way to use it apart from disabling the entire blocklist. This carries a considerable security risk, as no plug-ins will be blocked or set to Click-to-Play, including known malware. If you're sure you want to go through with it, set ''extensions.blocklist.enabled'' to '''false''' in [http://kb.mozillazine.org/About:config about:config].

Java platform and Java Deployment should be updated but there is no other version, always the warning to update but thats not possible

Java Platform 7u9 and Java Deployment Kit plug-ins are yellow and asked to be updated.
The problem is that there is no other version than I have already installed.
Even if I try to instal this latest version again I've get the message that I already have the latest version.
The same problem was with Flashplayer where I installed the latest version but three days Firefox asked to update the plugin.
The last one is now ok but Java Platform and Java Deployment Kit is hopeless.
Why it ask for an update if there is none?
What should or can I do? I always be careful and patch my pc if necesserry.
All my friends who are working with Firefox have the same problem.
Can anybody tell me whats going on here?
greetings, Mimi321

Hi
There is still an issue for me. When i check to see if add-ons are up to date it identifies "Java(TM) Platform SE 7 U9" as out-of-date and gives me an orange "Update" action. When i hit this it takes me to the Java website giving me "Recommended Version 7 Update 9". This is the one i've already got so i cannot get rid of the orange Update action buttons.
Furthermore, if i try the link earlier in this thread to test to see which version of Java i should be using it says "Congratulations! You have the recommended Java installed (Version 7 Update 9)" so i'm not sure what this talk of version 7.10 is about?

Firefox plug-in: Java Deployment Toolkit

JRE 6u17 (probably older versions as well) install for Firefox the plug-in as in stated in subject.
What is this plug-in good for?
What functionality will the user miss if he/she decides to deactivate/uninstall the java deployment toolkit?

Contrary to what BIJ001 suggests, the Java Deployment Toolkit Plugin is installed in Java SE 6 Update 10 and above.
More info for the Java Deployment Toolkit Plugin can be found at:
http://java.sun.com/javase/6/6u10faq.jsp#DT
http://java.sun.com/javase/6/docs/technotes/guides/jweb/deployment_advice.html
Ever since Java 6 Update 10, an NPAPI plugin and an ActiveX control (npdeploytk.dll and deploytk.dll, respectively) have both been installed by default with the JRE.
You should be able to find them under one or more of these folders (there are other locations you may find them on your drive):
C:\Program Files\Java\jre6\bin (both)
C:\Program Files\Java\jre6\bin\new_plugin (npdeploytk.dll only)
C:\WINDOWS\system32 (deploytk.dll only)
The this new functionality is the focus of attention for 2 recent vulnerabilities:

I "allowed" Java Deployment Toolkit, it made me upgrade java, and now there are ads everywhere

I was doing homework on masteringgenetics and there was this box in the top left hand corner that said to allow java deployment toolkit because some of the content on the website needed it so I clicked "always allow". This then took me to java's website to update java and I was gullible so I did. Now there are random ads on most websites I go to and if I stay on there it takes me to some random website. I've tried disabling all plugins, uninstalling java, uninstalling then reinstalling firefox, but it still happened. It doesn't happen when I use google chrome so I think it's a firefox thing (actually now it's happening on chrome too).

Oracle may be bundling other software with a Java update, so always be careful when installing or updating programs like Java and Flash and look carefully for any check boxes to installs such unwanted extras.
You can check in "Windows Control Panel > Programs" for recently installed programs (sort by installed time) to see if any suspicious software shows up.

Java Deployment Toolkit 6.0.200.2

Java Deployment Toolkit 6.0.200.2
== URL of affected sites ==
http://www.fsr.ac.ma/congres-sm2a/#

Same thing is happening to me, and I have no solution either.

Java deployment toolkit

My Java (TM) Platform SE 6 U23 6.0230.5 is disabled because it's known to cause security problems. Should I also disable Java Deployment Toolkit 6.0.230.5? Both are listed in the plug in section. Also Java Quickstarter 1.o is disabled in the extension section. Should it be?

I would update the JRE and JDT to the latest versions, which are 6 update 31. Or you can update to the version 7 branch, which is update 3. That will enable them for you and keep you safe from security issues. [http://www.java.com www.java.com] is where you can get them.

Java Deployment Toolkit and Japanese

I can't figure out how to enable Japanese in Firefox. Since following existing tutorials yielded no positive results, I tried installing the latest Java, but that only made things worse. Now I have two problems:
I still can't view Japanese characters.
I can't uninstall the Java Deployment Toolkit plugin.
The tutorials I've found on uninstalling the plugin don't work because I don't have the options they say to use. I'm using Firefox version 24.0 on Windows XP.

I only see the Java Deployment Toolkit plugin listed in the Add-ons

Hello everyone,
I only have Java Deployment Toolkit plugin 7.0.110.21 listed and enabled, and not Java Platform SE.
I tried the steps under: http://kb.mozillazine.org/Java#Enabling_Java, but nothing works.
Help! :-)

hello, in some instances firefox may not be able to detect that the java plugin is installed, because oracle made an error in registering the java plugin for mozilla-based browsers in version 7u10 & 7u11... this will apparently just be fixed with its 7u13 release.

Java 1.5.0_13 Cached HST files in %USERPROFILE%\AppData\LocalLow\Sun\Java\Deployment\host

We're using Java 1.5.0_13 required for use of Oracle EBS. After a recent failover test of Oracle EBS, users were not able to connect back to production after the DR testing was complete.
I discovered when launching a form, Java was creating a file in %USERPROFILE%\AppData\LocalLow\Sun\Java\Deployment\host named 376bdaf3.hst. Within this file is the IP address of our load balancer.
I believe this to be the cause of the connectivity issue. Those uninvolved with the DR testing were not affected.
I could find any documentation on these files much less how to disable them. Clearing Java cache doesn't seem to affect this file. The only way I could prevent its creation is make the host directory read-only, which didn't cause any apparent problems.
Has anyone faced this problem before? Is there something we can do to disable this?

Hi Andrew
Apologies for creating the same thread in a number of different forums. My intention was to grab the attention from as many forum users as possible.
Coming back to your solution, prior to your message, I didn't know anyting about Java Web Start. Having read your solution, I went back to Oracle's forum where the Forum's one of moderators Jan Carlin has blogged about the working of Oracle Forms with Java Web Start. [http://groundside.com/blog/JanCarlin.php|Forms and Java Web Start]
Having gone through the features of JWS, JWS sounds promising. But Oracle has not come out with white paper on JWS yet nor has it certified it officially yet. Hence at this stage I would not like to go with JWS. But I would certainly keep your solution in my mind whenever we decide to go for JWS.
Many thanks for taking your time out to reply to my query.
Cheers

Linux: /etc/.java/deployment/deployment.properties being ignored (JRE 7_17)

I'm trying to create a mandatory policy to roll out to users however I can't get the Control Panel to read the System Level deployment.properties in the location given by the documentation -
/etc/.java/deployment/deployment.properties
containing - deployment.system.config=/path/to/deployment.properties (world readable)
deployment.system.config.mandatory=true
To test I've set the contents of
/path/to/deployment.properties
to include - deployment.trace.locked=true
deployment.log.locked=true
as well as the defaults.
However if I fire up ControlPanel as a standard user I don't see either of the log checkboxes ticked - even if I removed the local user's ~/.java
Can anyone point me in the right direction?
I've also tried deployment.trace=true / deployment.trace.locked etc but that doesn't work either.
It's the standard Oracle JRE I'm using,
Any comments appreciated!
Thank you.

These is a problem with 7u17 and 7u21 for all users on all platforms. You can read more about it here (http://www.labareweb.com/java-1-7-auto-update-deployment-with-sccmmdt/) and here (https://blogs.oracle.com/security/entry/maintaining_the_security_worthiness_of) is the lead developer of Oracle admitted (at the end) that the enterprise tools for JRE is broken. It seems we're at their mercy at the moment.

Why does Firefox still tell me it's blocking Java Deployment Toolkit after I did the update?

On the "Mozilla - Check Your Plugins" webpage, I was told that the " Java Deployment Toolkit" was vulnerable. So I did the update. But afterwards I was still told the same problem. Why? And should I care?
Please see the attached screenshot.
The funny thing is... I visited two sites that use Java, one being Java.com, but I did not see the black banner message of blocking.

The Java Deployment Toolkit may be the latest version, but Oracle still hasn't fixed the security faults with that plugin; so Mozilla still has it on the Blocklist and disables it so far as to require the user to use "Ask to Activate". ''A "soft-block" - usable if needed, but needs user-action per implementation''.
Specifically, do you have a program on your PC that actually needs that Deployment Toolkit?
Or is your concern merely that it is disabled after updating Java?
Very few consumer applications even use that Deployment Toolkit, which is intended for people who develop Java applications or who use applications such as various Oracle programs in the workplace.
Going back to before Oracle bought out Sun Systems Java in 2010, that Deployment Toolkit wasn't being installed with the Java Runtime Environment for users. Java developers had to install a separate Developers Toolkit to get that Plugin - the SDK program had it.
