Hi Carlos, Please next time create a new post for your question. As for your question, on Windows, the default web browser engine is Internet Explorer which is now deprecated. If you use a recent version of the SWT library and if you use the latest preview of DJ Native Swing, you can force the use of the Edge runtime either by passing "JWebBrowser.useEdgeRuntime()" to the JWebBrowser constructor or using the system property "nativeswing.webbrowser.runtime=edge". On some systems, you need to explicitly...

I thank you for this browser, but I have a problem, it only loads Internet Explorer 11, it is very old, I have seen comments from Criss that you updated to Edge, I have not been able to with the .jar, could you help me please, so I can run it on another more updated browser, thank you very much.

Hi Andrey, DJ Native Swing uses the SWT library internally. SWT Edge implementation is based on the WebView2 component: https://www.eclipse.org/swt/faq.php#howuseedge You would need to find a way to solve the SSO issue with the WebView2. Here is a hint: https://github.com/MicrosoftEdge/WebView2Feedback/issues/550 I have seen mentions of the environment variable "WEBVIEW2_ADDITIONAL_BROWSER_ARGUMENTS" which could be set to "--enable-features=msSingleSignOnOSForPrimaryAccountIsShared", but it is unclear...

Hi there, we are using chrriis.dj.nativeswing.swtimpl.components.JWebBrowser component for user authentication over Azure Cloud SSO. And what interesting... it works fine when we are not using "EDGE runtime". However, when we use "EDGE runtime", Azure Cloud SSO fails. And the cause of the error is "Device ID" is missing on the authentication. Any ideas what should be changed here to make SSO authentication successfully with "EDGE runtime" option? Thanks!

Hi Chris, I've been monitoring this problem for a while, and the issue is not so much that it's a warning, but that when it occurs, the browser freezes for about 90 seconds, after which control is passed back to my app and it continues normally. Perhaps there's a code path that both leads to the reflective access warning and to this condition? I tried upgrading to 1.03 and the issue persists. Thanks for any help, Ithran
-
Hi, Sorry for the late reply... For now, this is just a warning. This is due to the module system introduced in Java 9. Perhaps I could pass "--add-opens=java.base/java.lang=ALL-UNNAMED" when I spawn the process responsible for the native stuff to get rid of the warning, but then I also need to test the version of Java to not use that option if < Java 9. Hope this helps, -Christopher

Hi, I'm successfully using JWebBrowser on 32 bit Linux (Centos 6) with the Mozilla interface. Occasionally, the browser will freeze and I see this written to the console: Native Command: [/usr/java/jdk-11.0.17/bin/java, -client, -Xms512m, -Xmx2048m, -Djava.library.path=/usr/local/javapos/wn/bin:::/opt/EpsonJavaPOS/bin:/opt/nextor/lib/psc:/opt/nextor/lib/psc/SupportJars:/opt/nextor/lib/jai:/usr/java/packages/lib:/lib:/usr/lib, -Dnativeswing.peervm.debug.printStartMessage=true, -Dnativeswing.localhostAddress=127.0.0.1,...
-
As I indicated in my last post, you need to force the use of the Edge runtime on Windows. This can be done using a system property. Perhaps the problem is that you are not using the lastest preview version, older (and official) version did not support Edge.

thank you Christopher, It works know, i have one more question : when navigate on sites JWebBrowser asks me to update compatible browser, and after i update the browsers i have , i'm still getting the same thing .

Hi, I don't think you have the relevant JAR files in your classpath. You need: - NativeSwing.jar - NativeSwing-SWT.jar - The SWT library conforming to your platform (64 bit, Windows, etc.) Hope this helps, -Christopher

Hi Chris, I wonder if you have taken a second look at the possibility of rendering the native canvas to a JavaFX node. This would close the gap significantly for many JavaFX developers out there. There has been success with embedding CEF (chromium embedded framework), but what I like so much about DJ is that I don't have to package the browser with my application, it simply uses the Edge WebView2 that's already on the users machine. When I want to use DJ JWebBrowser, I do one of two things. 1. Open...

Hello, I'm using JWebBrowser to display some page content inside our application. I've noticed that in some windows machines the content is not displayed properly the HTTP page that is not loading correctly is : https://ic2integra-web.mspe.globalblue.com/ As I said the issue can be observed only on some machines, in attachments working and not working example from two different PCs, using the same version of demo app (newest one). Both machines are windows 10. Can you let me know how we can start...
-
Hi Thomas, IE retires, but I don't know if the COM component that SWT uses will cease to work. I think I read that it will continue to work for several years. About the cookies that do not work, this is because Edge has some limitations and thus SWT cannot implement all APIs: https://www.eclipse.org/swt/faq.php#edgelimitations You are saying that something is not working with JDK8. What exactly is not working? Cheers, -Christopher
-
It did work on JDK 11 with the latest swt. Still can't get it to work on JDK 8 though.
-
After looking at the SendingCommands demo, I was able to create a workaround by executing the following javascript after the page was loaded: webBrowser.executeJavascriptWithResult("sendNSCommand(document.cookie);") Using the command received function, I got the web page cookies and was able to parse them. This should work just fine, but it still seems strange that the getCookie function simply returns null.
-
Also, the reason why I am using the edge browser is because I assume we will be required to when IE retires on June 15, 2022.

getCookie returns null when using Edge

Hi! I found out the solution. If not letting jpackage create runtime but creating it by jlink and pass it to jpackage everything works perfectly. In this case the runtime can be used from outside not only by the packaged app. There is bin directory and java under it, etc. Cheers, Lóránd

Using JWebBrowser from installed app
-
Hi, I am not too familiar with the jpackage tool. But one thing is sure: the native side that is manipulated by the Swing side needs to be in its own VM, so a separate java process is started. I don't know how a new VM can be spawned from an application packaged this way. If you do have a way to start a VM, for example by shipping the java exe, etc., then I suppose you could set a different process factory if the default one is not suitable: NativeInterface.getConfiguration().setPeerVMProcessFactory(MyPeerVMProcessFactoryImplementation)...

Is it posisble tho to someone pass files using code so that they can be used in links/images.. for example, instead of needing an external link for a image on the page, is it possible to just use logo.jpg... and somehow pass that image into the browser in the same way setHTMLContent is used?

Windows DPI Scaling Problem
-
I added the version "DJNativeSwing-SWT-1-0-3-20220201.zip" that applies the scaling factor to the mouse coordinates. There are other parts of the API that might not respect scaling, but which are probably not used anymore, such as printing a native component to an image. Unless someone actually needs that, I don't intend to fix scaling there. In the case of printing to an image, it is unclear how to solve it: should we assume that the passed in image on which to print has the unscaled bounds? Etc....
-

Dimencia posted a comment on ticket #78
Mouse coordinates should probably be okay once it's scaled; coordinates should still be based on the unscaled resolution, which judging by what it was giving previously, is probably what it outputs now Won't have a chance to try it for a little while, though, so I'm just guessing at what it's doing right now If that's not what it's doing, then yeah, your method sounds fine. The events should never give values outside of the bounds the user defined for the window (unscaled); but of course, the window...
-
Hi, The bounds occupied by the web browser should be fixed in version: 1.0.3-20220131 Please try with "DJNativeSwing-SWT-1-0-3-20220131.zip". I haven't done any conversion of the mouse coordinates for mouse events. I suppose that I would have to convert the physical pixels into conceptual pixels so that if there are physically 500 pixels Swing should receive an event for 400 pixels if the scaling factor is 125%. I am not sure yet if this could cause other problems... Any opinion? Cheers, -Christ...

I also attach the Java class that I am compiling and running. I use Java 11. 0.10. This is the script I use under Window to run the program: java -cp .;./build/classes;./lib/* -Dfile.encoding=utf-8 -Dorg.eclipse.swt.browser.DefaultType=edge Test My screen resolution is 1920 x 1080 while my Scaling factor is 125% (on Windows it should be "Change the size of text, apps, and other items"). Thank you very much Best Livio
-
Dear Christopher, The menu that is displayed after right-clicking is the one of Edge. See imagine attached.
-
Hi Livio, First, we should confirm that it is using the Edge browser (meaning that the system property was taken into account). One way to do so is to right click in the web page that is displayed, the menu is very different if it is Edge. It is a pity that I cannot reproduce the problem to find a solution at my end... If it is indeed Edge and you still have the problem, could you give me more information? - What version of Java? - What is your screen resolution? - What is the scaling factor in your...
-
Hi Christopher, Thank you very much for your help! I am using SWT 4.22, which is the latest version so that is not the problem. I tried to install Edge runtime but during the installation, the installer told me that it was already installed. I set the property by adding: System.setProperty("org.eclipse.swt.browser.DefaultType", "edge"); at the beginning of my code, but the result did not change: JWebBrowser is still (wrongly) displayed as in the JPEG attached above :-( Thanks again for your help...
-
Hi Livio, I am curious: have you tried upgrading the SWT library? https://download.eclipse.org/eclipse/downloads/drops4/R-4.22-202111241800/#SWT If you have and the bug is still present, you could try switching to the Edge runtime, to see if that makes a difference. To do so, you first have to make sure that the WebView2 component is installed: https://developer.microsoft.com/en-us/microsoft-edge/webview2/#download-section And you need to launch the application with that system property set before...

Ok, I changed the Zoom settings of IE when I open it to 100% but it does not solve the problem with JWebBrowser. Never mind, thanks anyway for your quick and kind replies :-) Have a nice day Livio

Well, check the zoom-related settings I mentioned, because in the end the way the PDF is displayed is by leveraging Internet Explorer as an integrated viewer. Cheers, -Christopher

Hi Christopher, Thank you for the quick reply. Actually I am interested in displaying pdf files. Therefore, Internet Explorer is immaterial. However, if I replace webBrowser.navigate("http://www.google.com"); with: webBrowser.navigate("http://www.cran.r-project.org/doc/manuals/R-intro.pdf"); The result is the same (see attached imagine). You asked me to check the zoom level in Windows display settings (and I guess I have to look for the same also in the Acrobat reader). I searched on Google but I...

Hi Livio, If you launch standalone Internet Explorer, is the zoom level set to 100%? If you check your Windows display settings, do you have a zoom level other then 100%? I have seen problems related to High DPI screens (and thus the use of these zoom factors) with Internet Explorer. I don't think Internet Explorer will ever support that properly. When time permits, I will investigate if the SWT library (which I integrate to make the browser possible in Swing) has made progress with other renderers...

Hi Devi, I think that if you use a recent version of SWT and if a Webkit browser is installed, then that would be used. But... I don't know the state of this support. Java client applications are less and less developed, so this project might be getting a bit obsolete. To force the use of Webkit, you might have to set this system property: nativeswing.webbrowser.runtime=webkit The requirements for SWT to load Webkit are explained here: https://www.eclipse.org/swt/faq.php#howusewebkit Hope this helps,...

This requires certain steps which are specific to this native integration, among which opening the interface and running events in the main of the application.
