How to embed jetty and webkit like Electron framework does? - java
We have distributed web application and front-end part of this application should be standalone desktop application and have integration with desktop apps such as telephony. I saw Electron framework and apps (for instance Slack) built on top of it and it is pretty good.
Does Java world have such a tool for embedding of jetty/tomcat and webkit browser to built native desktop apps?

Update:
See my test application on Java CEF: https://github.com/jreznot/cefc.
It uses Jetty/Swing/JavaCEF/Vaadin as HTML 5 Desktop Stack.
Final Update:
See my Electron+Java madness: https://github.com/jreznot/electron-java-app
It uses Electron with Java server side and Vaadin for application UI.
I recommend to use Electron instead of Java-Webkit bindings because it is mature framework and it has large community of JS developers.
I have search for similar solution in these last days and haven't found a totally fine solution.
These below is the more interesting partials solutions I have found.
Embed a browser (chromium) in java
I found two web site and is unclear what is the better solution:
jcef on github.com
build instructions
jcef on bitbucket.org
build instructions
I am not sure if these embedding solution will work well.
Please let me known if someone have found a quicker solution to embed web browser.
If you embed the browser into your code you have not trouble if the browser will update itself in the future and the user have your window container unless the standard browser window.
If you use an external browser you are sure on it well known behaviour but it can be change in the future and if this happens you have to update your application.
I choose to avoid embedded browser and reuse a standard external browser.
Embed http server
I like two solution I have found. All these solution can be use with minimal code change on your web application.
One thing is better you do is to make your web application a Maven application.
To do this in the past I have look at every library in web application class path and put in maven pom.xml dependency tree.
Spring-boot framework
Spring-boot is part of Spring framework.
It is a Spring projects: Spring-boot.
This project help a lot to start your web application.
Since you are developing a web application, you will add a spring-boot-
starter-web dependency in maven pom.xml
It standard embed server web is tomcat7/8 but you can change to Jetty8/9 or Undertow 1.1
Spark framework
This framework is a good alternative to Spring-boot. It is more concise and use Jetty as embedded web server.
I like Spring-boot because I am use to Spring configuration and use a mix of xml/annotation configuration and I like spring IoC. Using Spring-boot it easy to add other Spring constellation capability.
I hope that this can help you.
I think you can use wt. This is a system that takes a Qt based GUI application and rewrites the drawing mechanism from the usual desktop controls into html controls on a web page. IIRC its very transparent in that you only need to change a line or two of your original code. Qt is not java though, so I'm only pointing it out for completeness, its still pretty cool though.
But the simplest way would be to implement it using web technologies (eg HTML/JSP controls) so that it can be displayed as a web page easily, and then create a desktop app that uses the same html pages only wrapped as a 'executable'.
To create a desktop application you can either view the web page in an embedded browser in an application that exists solely to show the browser in a window, or you can use something like Microsoft's HTA system that presents web pages as desktop-style windows.

How to run a Swing application on a web page?
I have created a Swing application in Netbeans that is basically a chat system (between multiple clients and server using socket programming). Now I wanted to run this application on a webpage. Is this possible without changing any code?
Now I wanted to run this application on a webpage. Is this possible without changing any code? No. It would have to be a JApplet to be embedded in a web page, and applets have been effectively killed off. See Java Plugin support deprecated and Moving to a Plugin-Free Web. On the other hand, a desktop application (based on a JFrame) can be launched from a link on a web page using Java Web Start. Edit Scrap that advice regarding JWS, apparently it too is being deprecated as of Java 9.
Java integrated or embedded browser
I need a integrated or embedded java browser. I used WebEngine of javafx which support basic css as well html & java script but could not able to run flash file. Any way to do so. Or any other Project u know which could fulfill my requirement.
You can also look at JxBrowser Java library that allows embedding Chromium-based web browser control into Java AWT/Swing application. It supports both Java Swing and JavaFX. BTW: the browser control is totally lightweight. All rendering happens in a separate native process by native Chromium engine. The web page looks like it's displayed in Google Chrome.
Check those (although they are not JavaFX but I suppose that they can be used): http://lobobrowser.org/java-browser.jsp - pure Java http://www.javadesktop.org/articles/jdic/index.html - better imho, but no longer maintained
JNLP file and other requirements for deployment of JavaFX 2.0 application in web browser
I need to create a JNLP file for a online Application i have developed in JavaFX 2.0... I have no idea where to start since there is no documentation that relates a JNLP file to a JAVAFX 2.0 application on the web currently...at least none that I have found. I kind of would like this page to be a tutorial of how to go from code to deployment to a browser. I would like the application to load when the page loads. Similar to the ensemble sample for JavaFX 2.0.
There is documentation directly on javafx.com: http://docs.oracle.com/javafx/2.0/deployment/packaging.htm#BABFECGG But it is a bit complex, so you can opt for an easier way : install NetBeans 7.1 Beta, create JavaFX project there and click "Clean and Build". NB7.1 will create all required files. http://netbeans.org/community/releases/71/
What is "java web start" used for?
I was reading about java web start from wiki. Can someone please tell me What is it used for? A practical application of it; to make its use clearer. Do other languages like C++ / C# have anything similar? Thanks, Roger
Java Web Start is kind of like a successor to applets - it allows Java programs to be run from your browser (though unlike applets, they don't run within the browser). For a practical example, see the TopCoder Arena. http://www.topcoder.com/contest/arena/ContestAppletProd.jnlp Here, Java Network Launching Protocol (JNLP) is the protocol that defines how a Web Start application should be run (analogous to HTML telling a browser how a page should be rendered). See the Oracle tutorials: Lesson: Web Start Deploying a Java Web Start Application Java Network Launch Protocol
Java Web Start software provides the power to launch full-featured applications with a single click. Users can download and launch applications, such as a complete spreadsheet program or an Internet chat client, without going through lengthy installation procedures. With Java Web Start software, users can launch a Java application by clicking a link in a web page. The link points to a Java Network Launch Protocol (JNLP) file, which instructs Java Web Start software to download, cache, and run the application. I'm quoting the Java Tutorial lesson on WebStart For those of you who work with .Net something like Java Webstart is ClickOnce technology.
Java Web Start is used to write sandboxed desktop applications similar to Java Applets. Like applets they can be launched from a web browser, but they run in their own window - not inside the browser. It runs just like a normal application, but started from clicking a web page instead of having to download and run an installer. An advantage is that it's very easy to get people who are afraid of all the security warnings to try your application. Another advantage is that you don't need to keep the browser open while you run your application. You can even install a shortcut to your application onto the user's desktop so they don't need to touch the browser at all once they have run it the first time. The .NET equivalent is Click Once.
What is it used for? To roll out and keep updated an application to clients. Clients need "only" a Java Runtime installed. This may be more interesting to read.
Java webstart is used to deploy/install Java applications over the network. The alternative is to send an application (MyApp.jar) to the users who will run that directly. But if it is out-of-date, they could have collisions when the application talks to the server (for example, or other such badness). It also allows you to package all of the required libraries. This is a HUGE benefit. http://java.sun.com/javase/technologies/desktop/javawebstart/index.jsp
As mentioned above, it's a technology to allow you to 'push' an always up to date Java app to users. It's not often used on a consumer level, but has some adoption in a corporate atmosphere. It's best used in somewhat controlled environments, and is especially useful to push a specific version of client software to control a server.
Do other languages like C++ / C# have anything similar? Yes. Microsoft provides something called ClickOnce that provides a web-based installer.
Today i am looking for the same example about the Java web start... I thing this link will work for you,i have used as a beginner. Click Here As mention With Java Web Start software, users can launch a Java application by clicking a link in a web page. The link points to a Java Network Launch Protocol (JNLP) file, which instructs Java Web Start software to download, cache, and run the application.
We had a project, a plugin for Protégé, which is an ontology editor. Installing the plugin isn't that hard, but to give the user a quick impression how the plugin worked, we supplied a Java Web Start application on our site. The page is still active, the plugin may have some rough edges, since it hasn't been updated for a while ... http://dac.icore.at/one/solutions. I'm currently not aware of similar products for C/++/#.
Java web start is the 0-install solution in the java world. An application built to use Java web start (JWS) will be available as a link in a web site. This site will have the .jnlp extension. When a user clicks this link (and clicks the "execute" button of his browser) , the javaws.exe runtime will be launched. This executable will download the application and dependencies (libraries, images, and so on) and launch the application using the provided main-class of the .jnlp file). An extensive reference of JNLP content can be found at http://lopica.sourceforge.net/ref.html Examples of Java web start applications can be found at Swing sightings. Notice that, depending upon the chosen configuration, these applciations can also be automatically installed in start menu.
Java and Silverlight together forever
I want to display a silverlight web page inside my java desktop application. Does anyone know of a plugin or browser control that I can use to do this?
Embed an appropriate browser window into the Java app and it can load the SL - there will not be any interaction / communication between the two without some hacky code. Multiple browsers support SL but you are better off using the an IE based one at present, the chrome support is not official as I remember.
How about an iFrame? In the nutshell... Alternatively you can make a request to .Net app from within your java server code using something like HttpClient and then serve markup that way - would be relatively easy thing to do (relatively since if there authentication involved things can get complicated fast. And if you want (willing) to get "sophisticated" and you are using portlet technology there is WSRP For the desktop app I would go with HttpClient suggestion: get the content, parse it then do with it what you please unless that Silverlite app is also running as webservice then you have some additional options by utilizing components that can consume services
Eclipse's SWT provides out of the box web browser component based on IE and/or Mozilla engine. For swing application you can use one of ActiveX bridges, such as J-Integra or JDIC or EZ JCOM.
Use JDIC WebBrowser component
