Share a DLL between 2 java applets

I got this problem:
i'm working with 2 java applets (A and B) that try to use the same DLL.
It seems that when applet A loads this DLL, it locks access to the same DLL to applet B.
Is there a way to make this DLL accessible to both applets?
Can i store this DLL somewhere on client so applets A and B can access it concurrently?
Java says something like this: "File is used by another process"
thanks to all

Maybe the cleanest solution for you is to write a third utility class U which implements your native methods and load the library there. Then you can call the native methods of U from both A and B applets (as long as you add the U class to the classpath for both applets).

How to Use DLL Function in Java Applet

Hi all,
I have been assigned a task to develop java applet. The problem is, I need to use DLL functions in my applet to read records. Could you pls anyone guide me how to interface DLL and applet to read records with sample code?
I'm using JDK 1.5.0_06 and Windows XP OS. thanx..
best rgds,
jpdbay

You will need to use Java Native Interface JNI. Ther are many posts on the subject, please search, and this is the documentation:

Socket communication failure between Java applet and C++ application

I have a java applet that connects to a C++ application via Java's ServerSocket and Socket objects. THe C++ application is using the Winsock 2 API. The applet and application are running on an NT workstation (SP 6) and using IE (5.5) For a very simple C++ test applications the communictions work fine. Once more code gets added to the C++ application the portion of the socket that C++ listens to seems to close. Upon performing a recv call the return value is a zero. Microsoft insists this is a sign the Java side has shut down the socket. The Java applet can still receive messages from the C++ app but C++ cannot receive responses from the Java side. Java throws no exceptions and an explicit check of the socket shows no errors. Again, what puzzles me is that it works for simple C++ applications. Are there any known conflicts between Java and C++ in this regard?
I have inlcuded the basic java code segments below.
/ run Method.
* This method is called by the Thread.start() method. This
* method is required for the implementation of the Runnable interface
* This method sets up the server side socket communication and
* contiuously loops looking for requests from a external
* socket.
* @author Chris Duke
public void run(){
     // create socket connections
     boolean success = false;
     try {
         cServerSocket = new ServerSocket(cPortID);
         System.out.println("Waiting for client to connect...");
         cClientSocket = cServerSocket.accept();
         System.out.println("Client connected");
         // Create a stream to read from the client
         cInStream = new BufferedReader(new InputStreamReader(
           cClientSocket.getInputStream()));
         // Create a stream to write to the client
         cOutStream = new PrintWriter(
           cClientSocket.getOutputStream(), true);
         success = true;
     }catch (IOException e) {
         System.out.println("CommSocket:Run - Socket Exception(1) " + e);
         success = false;
     // if the socket was successfully created, keep the thread running
     while (success){
         try{
            // check socket to see if it is still available for reading
            if (cInStream != null && cInStream.ready()){
                // check for an incoming message
                String message = ReceiveMessage();
                // Send message to listeners
                Event(message);
            if (cInStream == null){
                success = false;
                System.out.println("CommSocket:Run - shutdown");
         }catch (IOException e){
            System.out.println("CommSocket:Run - Socket not ready exception");
            break;
// SendMessage method -
* Sends a text message to a connected listener through port specified by portID
* @author Chris Duke
* @param String message - This will be the message sent out through the server
* socket's port specified by portID.
   public void SendMessage(String message){
      cOutStream.println(message);
      if (cOutStream.checkError() == true)
        System.out.println("SendMessage : Flush = Error");
      else{
        System.out.println("SendMessage : Flush - No Error");
   }

a very simple C++ test applications the communictions work fine. Once more code gets added to the C++ application the portion of the socket that C++ listens to seems to close.
This quite strongly implicates the extra code in the C++ App. The firstly thing I would try would be telnet. Try connecting to both versions of the C++ Application and manually reproducing a proper exchange.
a recv call the return value is a zero. Microsoft insists this is a sign the Java side has shut down the socket.
A correct implementation of recv should return the number of bytes received, or -1 for an error. A zero return indicates no bytes received not a socket closed/error. This sounds like FUD to me.
Are there any known conflicts between Java and C++ in this regard?
I can see no obvious faults, though the code is incomplete, I don't think it's an sockets implementation issue, at either end, it sounds more likely to be a protocol/handshaking bug in the C++ App.

COMMUNICATION BETWEEN JAVASCRIPT AND JAVA APPLET: US$20 AWARD FOR SOLUTION!

COMMUNICATION BETWEEN JAVASCRIPT AND JAVA APPLET PROBLEM (Easy Filter Java Applet) -
US$20 TO ANYONE WHO CAN RESOLVE THE PROBLEM
To forum visitors:
I am prepared to pay a standard shareware fee of US$20 to a user who can resolve this technical problem.
If your advice resolves the problem, I'll forward the payment to your postal address (include your
address with your reply, and also your email address)
I am attempting to enable a HTML button (using Javascript's onClick command) to directly input a number into one of the parameter text boxes in the Easy Filter Java applet (ie, enter a new color value number in the text field of the standard Colors Multiplicator Filter interface).
The applet is Freeware and can be downloaded at: http://www.javazoom.net/applets/easyfilter10/EasyFilter10.html
(It is a very effective bitmap display and editing utility)
To achieve this, I am trying to access the part of the applet that defines and sets the textbox. The text box is defined in the .class file by accessing the parameter details in the genericfilter.txt file (accompanies the .class files). I need to access 'private String appletInitialize()' and then one of the 'textFieldParameters' which sets the textbox.
I understand the basic syntax for referencing the applet:
document.appletname.setString("An example"). However, accessing the text fields in this applet is more complex!!
Please can you recommend the correct Javascript syntax to achieve communication with the applet.
Thank you for your kind assistance.

I am using a Application in c dll calling from jni jar by java applet in firefox version 19.0 , the problem is click event message box will not working correct

I am using a Application in c dll calling from jni jar by java applet in firefox version 19.0 , the problem is button click event message box or popup window will not working correctly. Please any one suggest me the steps to overcome this not responding or slowness in the responding problem of Button click event.

Hello,
In Firefox 23, as part of an effort to simplify the Firefox options set and protect users from unintentially damaging their Firefox, the option to disable JavaScript was removed from the Firefox Options window.
However, the option to disable JavaScript was not removed from Firefox entirely. You can still access it from about:config or by installing an add-on.
'''about:config'''
# In the address bar, type "about:config" (with no quotes), and press Enter.
# Click "I'll be careful, I promise"
# In the search bar, search for "javascript.enabled" (with no quotes).
# Right click the result named "javascript.enabled" and click "Toggle". JavaScript is now disabled.
To Re-enable JavaScript, repeat these steps.
'''Add-ons'''
You can alternatively install an add-on that lets you disable JavaScript, such as
*[https://addons.mozilla.org/firefox/addon/noscript/ No-Script] (to disable JavaScript on a per page basis, as required)
*[https://addons.mozilla.org/firefox/addon/quickjava/ QuickJava] (to easily disable and enable JavaScript, automatic loading of images, and other content)
Thank you and I hope this helps!

On certain web sites(with java applets embedded or rich content),sometimes browser hotkeys are beeing used with other functionality (eg.: youtube uses ctrl + tab for sliding between player controls).How can I prevent this?

Thanks for posting this!
I would only mention that your definition is incomplete for this -
Contextual selector A type of Style Sheet Selector that
and that it's most often referred to now as a Descendent selector, not a contextual selector. It's basically the same as the Compound selector that you have already defined....

Difference between Java applet and JavaFX

Hello, all!
I am studying javaFX in general. As far as I understand there is no main difference between java applet and javafx, except javafx has different syntax and library simple to use. Is it right?

Basically, yes. But as you point out, it is supposed to be faster to develop in JavaFX...
For example, Processing allows to export to applet, and is strong on doing graphics, but to see if user has clicked on a circle, you have to check the mouse coordinates against the circle coordinates, or create your own Circle class: it is at a much lower level.
Likewise, you can use gaming frameworks like Slick2D or PulpCore, but they might be lacking on GUI (but perhaps faster). Or use Apache's Pivot, strong on GUI, but perhaps lacking a bit on graphics and animation.
It depends on your needs, if you prefer to stick to Java, etc.

What're the differences between JSP, Java Script, and Java Applet?

I am confused by the concepts: JSP (Java Server Page), Java Script, and Java Applet? What are their main differences?

I don't know about differences, but one of their main similarities is that each of them has a page in Wikipedia.
JSP
JavaScript
[Java applet|http://en.wikipedia.org/wiki/Java_applet]
There. That should give you enough information.

The difference between Java webstart and Java Applet?

Hi all!
I'm preparing deploy my application. But I'm in two minds I should deploy My application follow Java Webstart model or Java Applet Model.
if i deploy application by using Java webstart then what will I get benefit? and otherwise?
Could you tell me some advices?
Thanks!

Applet runs in the context of a browser, Webstart requires a small piece of software to be installed on the client and then when you click on your link/icon webstart downloads your application from the server and runs as a Java application (not within a browser).

How relevant is Java Applet technology in 2006 for wide web deployment?

How relevant is Java Applet technology in 2006 for wide web deployment?
I'm developing a website which requires deployment Internationally to as many users as possible. Many people advise to stay away from Java applets, others say only use Java 1.1 (AWT limitation), some say use Flash, others say stay away from applets and plugins altogether.
Of course it depends on the content. I have interactive 3D content currently powered by Java 1.1 applet BUT I have been using Swing to introduce custom GUI functionality but which I know may limit compatibility. I'm torn by this whole debate and what impact it will have on the relevancy of my website.
How many users out there have browsers that will cope with my content?
Then there's the issue of all the various different browsers nowadays. I'm testing for IE and Netscape on Windows platform, but what about other browsers and OSes on other platforms? I notice that some websites have a page with tables to show users what browser is and is not compatible with their web content. How far must a web developer go to test all these things exhaustively?
Then there's the issue of a 16MB download for the latest Java plugin if a user's system is not up to date. Can all modern browsers handle Java even with the latest Java download?
Or should I just tell the user to get a compatible browser? Another 10-20MB download, depending.
Or how about Flash? That reportedly has a vast International deployment base, but do I need to pay for a Flash editor / IDE / compiler? So far I've been using freeware (HTML, Java, NetBeans, PHP, MySQL, PNG images) to achieve excellent results within my ludicrously limited budget. The Flash Player is only a 930KB download, and that is quite user friendly even if I must tell a user to get the latest version � only 2 minutes download on a 56K modem or about 15 seconds on DSL followed by a 2 second really easy install.
Look here to see where Java ranks against Flash and others :
http://www.macromedia.com/software/player_census/flashplayer/
I know Java. I use it for apps and now applets. I get it to communicate with my server's PHP and MySQL. It works well on my machine, but will my applets work for millions of users world wide with few technical problems? Looking through Java forums I see developers struggling with Java Applets in Safari on OSX but not on Windows. Then another has problems with Applets in IE on Windows but not on Netscape. Then one browser struggles with key events . . . it's like a mine field out there and I'm struggling for clear direction.
Microsoft's support for Java has been poor. If I depend on Java Applets now and for the next year, then will they still be supported 3 or 5 years from now? Or will I have to write off this investment in Java development effort and then switch to something else? Or switch to something else now?
Does Sun Microsystems somewhere reveal how ubiquitous their JVM deployment is?
Perhaps I'm totally misinformed, but Java Applets seem to be dying out. I'd really love to hear from other active web developers out there doing stuff for wide deployment to mass markets.

Since my zwebsite is already using Java 1.1 for 3D visualization I've decided to standardize on Java 1.1 to gain maximum browser compatibility. To add another technology like Flash at this point may just complicate matters, especially for me.
I'm now converting my Swing GUI to AWT. It wastes a lot of time, but the effort should be worth it in terms of the deployment success rate - in theory at least :-)
Just imagine if Java 1 had Swing . . . dream on!
In the deployment stats noted in my first post on this thread they state that Java has 86% world wide desktop deployment. Problem is that I bet that figure only relates to Java1. I wonder what pathetic percentage is true for Java2?
Regarding the use of Java for content rich dynamic content for world world wide web browser deployment . . . I'm rather disillusioned at this point. It seems for this application Java is stuck indefinitely at Java1 and the cool things they developed after that cannot be used effectively. Please note that I am ONLY referring to wide browser deployment. For stand-alone apps and targeted web deployment (where you can reasonably expect your user to upgrade his/her system for a good reason) Java is still very cool.
As for Java WebStart: I can see the uses for it, but it just does not fit into the browser application where the general public enter your web pages and see cool content inside the essential context of your webpage. This last point is vital for any serious web site. If the object of the site is to deploy a useful app to the user (like a forex trading front-end with GUI) then use Java WebStart by all means.
After this website, I'll invest in Flash. I'm sure Flash is not without its share of issues, but it has 97% deployment of nearly the latest versions and user download/upgrade is under 1MB. On top of that it does not seem to suffer from corporate relationship woes like those between Sun and Microsoft.
After all, Flash is labelled as a 'player' and not a Virtual Machine. Mass users out there want to play rather than know about complex and bulky IT stuff.

I am trying to use an education program that needs Java applets to install and use and it will not use Safari. When I download IE from the web it will not install. How can I get a browser that will work on my MacAir for travel use of this program?

I am trying to use and education program that needs Java applets and it will not run on Safari. IE will not install from the web. How do I get a browser that will work to install so I can use this program when I travel.

Try using FireFox. IE will only run on a Mac if you run Windows on the Mac.
Windows on Intel Macs
There are presently several alternatives for running Windows on Intel Macs.
Install the Apple Boot Camp software. Purchase Windows 7 or Windows 8. Follow instructions in the Boot Camp documentation on installation of Boot Camp, creating Driver CD, and installing Windows. Boot Camp enables you to boot the computer into OS X or Windows.
Parallels Desktop for Mac and Windows XP, Vista Business, Vista Ultimate, or Windows 7. Parallels is software virtualization that enables running Windows concurrently with OS X.
VM Fusion and Windows XP, Vista Business, Vista Ultimate, or Windows 7. VM Fusion is software virtualization that enables running Windows concurrently with OS X.
CrossOver which enables running many Windows applications without having to install Windows. The Windows applications can run concurrently with OS X.
VirtualBox is a new Open Source freeware virtual machine such as VM Fusion and Parallels that was developed by Solaris. It is not as fully developed for the Mac as Parallels and VM Fusion.
Note that Parallels and VM Fusion can also run other operating systems such as Linux, Unix, OS/2, Solaris, etc. There are performance differences between dual-boot systems and virtualization. The latter tend to be a little slower (not much) and do not provide the video performance of the dual-boot system. See MacTech.com's Virtualization Benchmarking for comparisons of Boot Camp, Parallels, and VM Fusion. A more recent comparison of Parallels, VM Fusion, and Virtual Box is found at Virtualization Benchmarks- Parallels 10 vs. Fusion 7 vs. VirtualBox. Boot Camp is only available with Leopard and later. Except for Crossover and a couple of similar alternatives like DarWine you must have a valid installer disc for Windows.
You must also have an internal optical drive for installing Windows. Windows cannot be installed from an external optical drive.

Forms Client Java Applet waiting several minutes

Hello,
We use Forms 10.1.2.0 and html/javascript/plsql applications.
All forms applications are working but
we have the problem that from time to time the client java applet must wait minutes until there is an answer from the forms-servlet (especially when there is high activity in the system).
More than one user is working in the form with high activity - the applet sends a request
over the network - after 4 minutes the result is shown and you can go on working
without problems.
So a lot of users think the application has crashed and terminate before.
The applet shows no error messages.
There is no sign that there is a lost connection between applet and servlet.
It is not reproducible. That means you can work 2 hours and everything is ok
or you work 5 minutes and you have to wait.
network problems?
firewall problems?
do requests of the forms servlet to the database have minor priority on the application server
than html/plsql requests?
any ideas?

when the problem occurs (user has to wait 3-4 minutes) we found in the log
3 heartbeats from the forms client within 2 seconds ?
after 3-4 minutes the forms client is ok (user can go on working)
and the pings are every 2 minutes (like it is expected).
The application.log file may contain duplicate posts requests with
identical pragma header numbers, indicating that the client
is resending
requests due to network packet losses. Under normal circumstances,
only the last Post request, terminating a Forms session,
should contain
a duplicate pragma header number.
...a network problem ?
anyone else who had the same problem ?

Referencing a "locally installed" Java applet from a server-based HTML page

How does one reference a "locally installed" Java applet from a server-based HTML page (i.e. via the applet, object, or embed tags)? I have seen references in documentation that this is possible, but I have not seen any examples. I have tried a few things, but nothing seems to be working.
Some background...
I'm working on a web site that aggregates Internet video. For many users, I would like the site to work "without" requiring Java to be installed (or any prompts, etc.). This version of the site allows users to stream videos directly over the Internet and does not require any sort of access to the local system.
However, in addition, I have a download manager that can be installed on the local system. Currently, it's a Windows-based "service" that is always running in the background, downloading files, etc. (with plans to later support other OSes).
My dilemma is trying to communicate between my web site running in the local browser (executing JavaScript code) and the download manager. I call this component the "gateway". I need the gateway to be able to do the following:
1) Pass user credentials from the web browser UI to the download manager (so it can communicate with my servers).
2) Check the status of downloaded videos
3) Launch a local media player (such as Windows Media, QuickTime, etc.) (or perhaps tell the download manager to launch the media player).
Under Windows XP, I have an ActiveX control that can do these things. It communicates with the download manager via reading/writing to a shared XML configuration file.
Unfortunately, under Vista and IE7 Protected Mode, ActiveX controls have become very restricted and my gateway no longer works. As such, I am looking at using Java for the gateway (also giving me the additional benefits of supporting additional browsers and OSes).
From my understanding, I believe I can created a "face-less" Java applet, whose methods can be called from JavaScript. Ideally, I'm thinking I could install the applet onto the local system at the same time the download manager is installed. This would give the applet the security permissions it needs to communicate with the download manager.
Thanks for any help and suggestions!

Hi,
Put the .jar file and the .class file in the path mentioned in one of the aliases in the plsql.conf file like /images or create
a seperate directory and create an alias like /applets "path" in the plsql.conf file.
<html>
<body>
<applet code=com.chartapplet.chart.BarChartApplet
codebase=/applets/
archive=/applets/chart.jar width=300 height=200>
<param name=background value="white">
</body>
</html>
Hope this helps.
Thanks,
Sharmila

Java Applets do not run when UAC is enabled on Windows 7

HI,
I'm deploying Java 6.0_26-b03+ on Windows 7 and experiencing following problem:
Java applets do not run as standard domain users in Internet Explorer 9 on Windows 7 when UAC is enabled (i.E. http://www.java.com/de/download/installed.jsp). When logged on as Administrator or start IE9 as Administrator java applets do run.
If I diable UAC an log on as normal user then applets do run. Applets then still run if UAC is re-enabled again. It seems that UAC needs to be disabled for the Java Plug-In to register something in user context (assumption). If this registration happended Java applets do run also for standard Windows 7 users if UAC is enabled.
Since we're planning a corporate Windows 7 rollout (>800PCs) we cannot do this manually on every computer. Ther must be any solution for this problem.
Does anybody have the same problem and has already found a solution?
This is the content of the error log file generated when a standard domain user tries to run http://www.java.com/de/download/installed.jsp

Since we're planning a corporate Windows 7 rollout (>800PCs) we cannot do this manually on every computer. Ther must be any solution for this problem.If you're doing a corporate rollout of that size then surely you're just making an image of the desired configuration and just duplicating it onto the 800 PCs? In which case you would just configure IE appropriately as part of the image.
Or alternatively you are manually configuring each of the 800 PCs, in which case this would be just one more thing in the checklist.

Java Applet - slow response over WAN and fast on LAN

Hi All,
Using Tomcat we have a Java applet that runs very slow over the Internet but just the opposite on the LAN (fast). On our website we have a link that we click which initializes the application. it is very slow but if the same link is clicked on the LAN it is very fast in responding. We have a 10MB internet connection and even when testing with very little traffic after peak business hours we have same results.When closing the browser and reopening it is much faster the second time. This tells me it is being Cached. If I go to a system that has never accessed the applet we are very slow again. We are hosting this application for a 3rd party so we did not write the code. This company is finger pointing at Router and I am finger pointing at Java application itself maybe not being optimal.
I am attaching "debug" info from Java Console. Can anyone identify any issues from this debug output or familiarity with this type issue. Your insight is greatly appreciated.

Hi Geoff,
Thanks for posting here.
Have you checked your internet edge router ? and make sure there is no any speed limitation set on it , like QOS.
