DeployJava.runApplet & JRE 8
I have the latest/greatest JRE 7 (1.7_51) installed. This is the at the 1.7 security baseline.
In my web page I am trying to launch an applet that runs on 1.7 like this:
var version = '1.7';
deployJava.runApplet(attributes, parameters, version);
I am informed that my plugin has security vulnerabilities and it directs me to install JRE 8 update 25.
2 questions:
1) Why is it telling I have security vulnerabilities when I am at java 7 security baseline?
2) Why is it trying forcing Java 8 family on me?
The latest 7 is 7u71, which you can find here: Java Downloads for All Operating Systems Version 7 Update 71
Try installing 7u71 and reply back about what messaging you see after that.

DeployJava.runApplet considered malware
hello Sun,
While I think your efforts to improve the ease of Java deployment are admirable, I have an issue with the overall operation of "http://java.com/js/deployJava.js":
The suggested download includes the Yahoo toolbar checked by default.
I feel that not only is this deceptive (the user should have a choice up front, as on the main Sun Java distribution site), but the opt-out nature gives off the impression of my site promoting malware.
I will continue to be part of this new deployment strategy, to file bugs and try to help improve the process, because I think this drive is important. But this new method will lose my support if this malware problem is not addressed.
Also, in terms of experience, it would be a huge benefit if the installer popped the viewer back to the referring site when it finished. The process is hard to follow right now.
Best Regards,
Brien ColwellThe latest 7 is 7u71, which you can find here: Java Downloads for All Operating Systems Version 7 Update 71

DeployJava.js doesn't work in FF 3.0.11?
I have the following html code for running my applets:
<script src="http://java.com/js/deployJava.js"></script>
<script>
var attributes = {code:'test.MyApplet.class',
archive:'MyApplet.jar,MyApplet_media.jar,MyLib.jar',
width:907, height:653} ;
var parameters ;
if (deployJava.versionCheck('1.6.0_10+')) {
parameters = {image:'animated_loader.gif', boxborder:'false', centerimage:'true'} ;
} else {
parameters = {image:'static_loader.gif'} ;
var version = '1.5' ;
deployJava.runApplet(attributes, parameters, version);
</script>It works fine in FF before 3.0.11 and IE 6-7, but FF 3.0.11 freezes and doesn't respond to user..
I've already created a bug on bugzilla.mozilla.org for sure. https://bugzilla.mozilla.org/show_bug.cgi?id=498305
Edited by: MrRed on Jun 15, 2009 3:37 AMPlease contact PriceBlink for assistance with your issue here: http://www.priceblink.com/webcpns/page.php?sp_id=5
As for the hanging please see the following:
'''Try the Firefox Safe Mode''' to see how it works there. The Safe Mode is a troubleshooting mode, which disables most add-ons.''
''(If you're not using it, switch to the Default theme.)''
* You can open the Firefox 4.0+ Safe Mode by holding the '''Shift''' key when you use the Firefox desktop or Start menu shortcut.
* Or use the Help menu item and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
''Don't select anything right now, just use "'Start in Safe Mode"''
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shift key) to open it again.''
'''''If it is good in the Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one.
Please follow the [[Troubleshooting extensions and themes]] article for that.
''When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.'' -
Important addition to deployJava.js
Hello,
We slowly started to use deployJava.js on our produciton servers, and except few problems with Mac, it works pretty good. Today we needed dynamically (on a click), to populate a DIV with code like this, to start an applet.
<script>
var attributes = {codebase:'http://java.sun.com/products/plugin/1.5.0/demos/jfc/Java2D',
code:'java2d.Java2DemoApplet.class',
archive:'Java2Demo.jar',
width:710, height:540} ;
var parameters = {fontSize:16} ;
var version = '1.6.0' ;
deployJava.runApplet(attributes, parameters, version);
</script>And the reason why we don't do it at page load, because we don't want to run an applet everytime somebody visits the page, only when they click on a button. So, the problem was, that deployJava.runApplet method, which calls writeAppletTag method uses document.write(), which completely destroys content of the page. So, we had to make a local copy of deployJava.js, and change document.write() to just return us a string, which then we populate using innterHTML, and applet worked like a charm.
So, since it's not a good idea to have a local copy of this deploy js tool, I would like to ask Sun to create a special method, which would return a HTML instead of using document.write directly.
Thank you in advance,
--DmitriQuick and dirty workaround:
function activateApplet()
var intercepted = ''; var got = document.write;
document.write = function(arg){intercepted += arg;}
deployJava.runApplet(attributes, parameters, '1.6');
document.write = got;
domElem.innerHTML = intercepted;

DeployJava.js ,Applet Deployment errors?
Some great work has been done on applet deployment. ref: [Applet deployment toolkit |http://blogs.sun.com/thejavatutorials/entry/deployment_toolkit_101 ]
I've been trying to use this tool with considerable frustration. I'm serving internet applications on Godaddy.com and jar file usage is problematic during development with them. You have to wait for up to 24 hours to deploy .jar contents. What the fix? Use straight up classes to prove out an application. I know that I have users without java browser add ins, and I'd like to use the deployJava routine to keep things easy (for me!)
Problem is that the deployJava.js defaults are set up for JNLP and .jar files. For anybody stuck with "Exception: java.lang.ClassNotFoundException: ..." errors, with deployJava, and you are only using .classes and not .jar files, you should be aware of the following:
You have to specifically add the codebase_lookup parameter to the deployJava routine. [ reference: Codebase_lookup |http://java.sun.com/javase/6/docs/technotes/guides/plugin/developer_guide/special_attributes.html] This script assumes codebase_lookup = false. Thats not good for us xxx.class only folks.
suggested solution:
<script src="http://java.com/js/deployJava.js"></script>
<script> var attributes = { codebase:'classes',
code:'directory/cool_function.class',
width:1000, height:650 };
var parameters = {codebase_lookup:'true'}; <----- default behavior is 'false'
deployJava.runApplet(attributes, parameters, '1.6');
</script>
Info offered here in case anybody else gets stuck on the same errors as I.
thanks for reading. --Zipzilti wrote:
I have something that could be improved in the deployJava.js.So don't tell us. Raise a bug report through [http://bugs.sun.com/bugdatabase/].
I'm sure this is something which could be done easily.In that case, make sure your bug report includes the changes to be made to the JS. Bug reports with code solutions will likely be given a higher priority than reports where the reporter reckons it will be easy for someone else to do the changes. -
Applet-tag in deployJava.js - really!?!
I have studied the deployJava source, and am surprised!
From what I can deduce, the script embeds an invisible "object"-object or an "embed"-object when it is initially loaded.
But the call to deployJava.runApplet() then actually embeds an "applet"-object!
Isn't the applet tag long since depreciated?!?
Also, why not simply make good use of the initial "object"- og "embed"-object, and place the applet there?
I will comment on major lacks in a separate thread.Nope. Oracle doesn't even fix the bugs in this forum - thats how much they care.
The best you can get is someone working on a certain API or spec to comment in the respective forum. It has happened that someone from the JSF group commented on JSF related topics (usually mentioning bugs) for example. But it is rare. -
DeployJava.js and using css display:none;
Hi all,
I am using the deployJava.js to add an applet to a page.
The applet is on a tab. My webpage has a few tabs and when you click from one to another using css I make a certain DIV disappear using display:none; and then to make the other DIV visible I use display:block;
As I flick between tabs my applet has problems. Sometimes its loads and sometimes it doesn't. The documentation says you should only call deployJava.runApplet once, so maybe this is the problem. Any ideas how I should avoid this?
Thanks,
CormacHello Doktat,
I also agree with you. This is a very annoying.
My web application has a number of tabs and as you flick through them I use display:none; to hide certain divs.
Unfortunately different browsers seem to handle differently.
On Firefox, if I go to a different tab. My Applet is Stopped and when I go back to the original tab, my applet is redeployed and started again. This looks bad and also sometimes my applet doesn't show up at all, but maybe that is because I am calling deployJava more than once.
On IE 7, everything seems to work beautifully and as I move between tabs the applet isn't started and stopped and deployJava only seems to be ever called once.
This is frustrating, web pages are more complex now and java needs to fit in with this new complexity.
I may have to move back to a pure javascript solution now. But I like to develop in java, so I keep pushing it to my manager and colleagues. Then it fails on something simple like this. I've been burnt before by applets and now it seems I am burnt again.
I do hope that they think more about haw applets fit into more advanced situations.
Talk later,
Cormac -
DeployJava.js and HTTPS Problem
I'm using the following code for my applet:
<script src="https://www.java.com/js/deployJava.js" type="text/javascript"></script>
<script type="text/javascript">
var attributes = {
codebase:'.',
code:'com.myclass.class',
archive:'/applets/myprogram.jar',
width:715,
height:340};
var parameters = {
java_arguments:'-Djnlp.packEnabled=true',
locale:'en_US',
systemVersion:'${settings.systemVersion}',
var version = '1.6';
deployJava.runApplet(attributes, parameters, version);
</script>The applet is hosted on https://mysite.com/myfile.jsf, when a user that has never had Java installed on his machine goes to my applet page it takes him to the Sun Java download page. After wards the user is taken to:
http://https//mysite.com/myfile.jsf
This is obviously an invalid link and instead should go back to the original URL. This does not happen and works correctly if the server is using http instead of https. Any ideas on how this can be fixed?Apparently no one has reported this is a bug on the bug parade. I did that, for what it's worth. I am shocked that this has been allowed to remain open for two years.

Is IE11 compatible with deployJava.js?
I installed Windows 8.1 and tested WEB-START with Javascript(http://www.java.com/js/deployJava.js).
It worked fine with Chrome but not with IE11.
Below code returns empty.
deployJava.getJREs();
And below function redirects to Java Installation page.
deployJava.runApplet(attributes, parameters, '1.6');
Did anyone succeeded running WEB-START with JNLP file?As a temporary solution, you can modify deployJava.js adding a condition in line 1013
1013: if ((browser.indexOf('msie') != -1) && (browser.indexOf('opera') == -1)) {
new version
1013: if ((browser.indexOf('msie') != -1) && (browser.indexOf('opera') == -1) || (browser.indexOf('trident') != -1)) {
Since IE11 doesn't send anymore MSIE in the useragent string (see previous Stefano answer for details) the Trident string must be checked to identify new IE version.
Hope that Oracle will fix this asap. -
Copy in sand-boxed app. in 1.6.0_24+

<h2><a name="summary"></a>Problem Summary</h2>
A security bug was fixed recently in the JRE (1.6.0_24 in Sun's JRE). The result of the fix is that sand-boxed apps. no longer provide 'Ctrl-c' copy (or cut/paste) functionality by default on text output controls like JTextArea & JTable.
While Ctrl-c copy no longer works by default, it is possible to add the functionality back in for any applet run in a 'Next Generation' Java Plug-In. Since Java Web Start existed, JWS provided sand-boxed copy via. the JNLP API's javax.jnlp.ClipboardService, & since Sun 1.6.0_10, & the next gen. plug-in, embedded applets can be deployed using JWS & can access the JNLP API.
I have redesigned an applet that relied on the old functionality, to now use the JNLP API Services if available.
<h2><a name="question"></a>Question</h2>
Does it work for you?
To answer that question:
<ol>
<li>Surf on over to the applet at http://pscode.org/prop/js.html and attempt to copy the data. See the instructions in the page for details of how to copy using the old and new forms of the applet. If the button appears, you should be prompted as to whether to allow the copy.
<li>Paste the data here (assuming the copy is successful). Or report if it fails to copy or the applet fails to appear.
</ol>
<h2><a name="egoutput"></a>Typical Output</h2>
This is what you might see at the applet.

<h2><a name="results"></a>Accumulated Results</h2>
<p>The first form of the applet showed a variety of problems with 'post copy focus', if the security prompt appeared in the JWS form of the applet.

The security popup really messes with the focus in Firefox (3.6.16) though.Not saying you're wrong, but I'm using FireFox 3.6.16, as well, and I have none of the focus troubles you've described.Cannot reproduce it now either. Weird.I got the impression you were referring to keyboard focus, so I did some further tests on focus behavior. The test results are listed in the Accumulated Results table on the 1st post.
The only browser so far that works as I'd expect, or at least as I'd like, is IE.
Applets and keyboard navigation have always been a PITA. Some time ago I vaguely recall seeing an update involving a new parameter to regulate initial focus (applet or page, ..or another applet), but for the life of me I cannot locate it now. Given that it was a parameter for initial focus, I doubt it would help in this case.

Let me know if anyone want to look at entire messages in java console.
for all the classes in jar which is signed.

In the above script I have tried various combinations like codebase, code, type, archive. finally i kept the minimal attributes and parameters.
Kindly note my applet is working fine in the browser. But I think because of the try again messages in java console it is taking time to load the applet ?
Any help on this highly appreciated. I have almost spent my week trying to remove these messages.837182 wrote:
..the last message of fetching resources japllet.jar is there as i changed the location. .. How? To what? I now note the applet Jar uses a version number, which JaNeLA fails to take into account.
..but how about rest of the messages, How to get rid of those ? ..Although I wrote the software, in conjunction with others, we did not configure it to send us an email when someone runs the software. Because of that (and hopefully unsurprisingly) I will state that I do not know what JaNeLA reported. OTOH I will make a WAG that there was an 'invalid content' message somewhere in the report.
Have you checked the JaNeLA Help page? It is the first place to check the error messages.
Some notes:
<li> Most of the errors are produced by J2SE inbuilt tools, and are messages common to XML validation. Search the net for them and you should find many hits.
<li> You can 'ignore' the warnings and optimizations. They are intended to identify things that might or might not be relevant. JaNeLA is unable to tell, and prompts you to make an informed decision.
As to whether it matters, consider this. I dealt with a failed JNLP launch that came down to illegal characters in the application title field. That is not something that JaNeLA even checks. But the simple principle is: Garbage In, Garbage Out. Before even considering why a JWS based launch is failing (or not working as you expect), it pays to ensure the input files are as logical and valid as we can make them. Otherwise 'all bets are off' as to how JWS clients will parse and act (or not) on the JNLP.
Reviewing the original problem now that you have at least run the JaNeLA tool. Just as an 'out there' suggestion, try adding a codebase_lookup='false' parameter into the applet code (JNLP launch file(1)). That attribute is only relevant to applets that can use loose class files & JWS should not need that, but it might indicate a JRE bug if it speeds things up.
1) ..Oh heck, throw it into the deployJava.js script as well. It will probably not help, but cannot hurt.
BTW: How big is apllet.jar in bytes? How 'slow' in seconds/minutes is slow? What is the network bandwidth of the testing machine(s)?
And now I remember to mention:
1) 'apllet' -> 'applet'.
2) Please use the code tags when posting Java or JavaScript code or snippets, XML/HTML/JNLP or input/output. For details see the 'sticky post' on the top of the forum thread listing. It is still possible to edit your original post to add the code tags. -
Getting JNLP error: "exception: Unable to load resource:-"
I've posted this question in Stackoverflow... but didn't get any answer...
Hi Guys,
I'm brand new to JNLP.
I've been trying to fix this for straight 2 days... I have no clue...
I've a dynamic web project in eclipse. And I wanted to append an Applet in html. It works fine, if I append it without using jnlp. But if I use jnlp, its throws exception...

- I really don't understand where the hell "/jars" coming from???
- My project name is "DaaS" and my jar, html page and jnlp page are in same directory. And I'm running my html page on tomcat-7 server.

Edited by: user1202074 on Feb 7, 2012 4:24 PMIt must be coming from the commented-out <applet> tag somehow.
You aren't specifying an 'id' element. See the Deploy Java Toolkit documentation. -
I'm crazy!Applet and JNA Error:Library 'jnidispatch' was not found!
Hi all,
sorry to bother you, I really have no idea how to do JNA and Applet. I'm hardly mazy, man.
Every time it will throw an error to me :

here is the structure of my program:
Applet code :

import javax.swing.JButton;
import javax.swing.JPanel;
import com.sun.jna.Native;
public class JNAApplet extends JApplet {

kernel32 = (Kernel32)Native.loadLibrary("Kernel32", Kernel32.class);
if (kernel32 == null) {
System.out.println("load kernel32 fail!");
} else {
System.out.println("load kernel32 success!");
private void createGUI() {
JPanel panelCenter = new JPanel();
JButton butTest = new JButton("Test");
panelCenter.add(butTest);
setContentPane(panelCenter);
}When I run it on debug mode, it is ok! but when I deploy it , it will throw above error message to me.

Can any one help me? Thank you very much!!!!Hi AndrewThompson64:
Did you mean the JNA project? Or are you refering to JNI, or ..something else?Yes, I mean is that I wanna jna.jar to replace JNI to code with Applet. I want Applet can run native library(.dll files).
That reads like so much nonsense to me.Sorry fo that.
Was there any 'caused by' part that you trimmed? I expected to see something to do with 'Security' or 'AccessControl'.Sorry, I can't saw any 'cause by' subsentence there. This message is just gain from Applet Console.(Is there any method to gain more message?)
About 'Security' and 'AccessControl' I just modify my java.policy file to allpermission. Subsequently, I signed all jar files.
For now I have 3 jar files(all have been signed ):
--example.jar : for this little program.(code include applet and application entry)
--jna.jar
--win32-x86.jar : include kernel32.dll and jnidispatch.dll for win32 and x86.
and 2 JNLP files:
--JNAApplet.jnlp the entry is JNAApplet.class (this jnlp does not work)
--JNAApp.jnlp the entry is JNAApp.class (this jnlp works)
And for now new error message show like this:
Exception in thread "thread applet-JNAApplet-1" java.lang.UnsatisfiedLinkError: Library 'Kernel32' was not found by class loader sun.plugin2.applet.JNLP2ClassLoader@4aeb52

Did you mean invoke?
Revoke: To annul by withdrawing.
Invoke: To call on.Yes, you got it. Thank you.
The JNLP file is invalid. ..I was about to put my 'standard' text here, but I'm sick of saying it. Search the forum for my posts - 50% of them, at least, mention validation and how to go about it.
Also, the applet-desc requires a documentbase.Thank you, I really think I have some invalid section. But I can't find it, and you said 'Search the forum for my posts - 50% of them...' , I can read the JNLP structure on site of sun and I can to read you post too(I'm doing like this).*I only want to know about how to load "native lib like *.dll" properly*.
What 'officer site'?I mean jna project site. Sorry for ambiguity.
Please fix that sticky '!' key. One '!' indicates astonishment, while two or more typically indicates a bozo. Thanks for your advice. Because I tried to find solution do my best lasting two days. I got nothing. I'm sadness.
here post my new files:

White border around full-size applet
I try to display an applet which spreads over the complete size of the browser window using a script element like this:
<body>
<script src="http://www.java.com/js/deployJava.js"></script>
<script>
var attributes = { code:'MyApplet.class', width:'100%', height:'100%' } ;
var parameters = {jnlp_href: 'my.jnlp'} ;
deployJava.runApplet(attributes, parameters, '1.4');
</script>
</body>
However, the applet still shows up a little smaller as the browser window so that it appears to be displayed within an approximately 5 pixel white border. Does anybody know how to get rid of this border?Ups, my fault. It was simply the margin from the HTML body ;-)

Embedded Java Applet NullPointerException in JSPX pages
We have a ADF web application programmed in JDeveloper 11g (11.1.2.4.0), which was migrated over from a 10g (10.1.3.5.0) project
Within the application, occasionally, we need to call a Java Applet which is placed in a public_html/applet folder. The jars show up in the Web-Content tab of the ViewController in the Application Navigator, just like it did in 10g.
The applet tag looks like this:
<applet height="100" width="100" code="applet.SetupApplet" archive="applet/SSetupApplet.jar">
<param name="debug" value="true"/>
</applet>
I've also tried calling the applet with the Java deploy applet script
<trh:script source="http://java.com/js/deployJava.js"></trh:script>
<trh:script>
var attributes = {code:'applet.SetupApplet',
archive:'applet/SSetupApplet.jar'};
var parameters = {} ;
var version = '1.6' ;
deployJava.runApplet(attributes, parameters, version);
</trh:script>
When I navigate to the login.jspx page that has this tag, it pops the Java Console open, but doesn't actually run the applet (or show the prompts to allow using the Applet). Instead, the applet is shown with an error and the error says "NullPointerException". I've double-checked the path and it's correct (with incorrect paths, I get a ClassNotFoundException). In the application server logs, I see the following error:
<Warning> <Socket> <BEA-000449> <Closing socket as no data read from it on IPADDRESS during the configured idle timeout of 5 secs>
I created a normal .jsp file that's outside the ADF Faces Context in the applet folder. Navigating to it with the same applet tags does have the Java applet run without the socket error. The same code in 10g works fine.
Is there anything I'm missing?
Thanks.Hi,
this is how I did it in 11g R1: http://www.oracle.com/technetwork/developer-tools/adf/learnmore/71-adf-to-applet-communication-307672.pdf
