I have my javaFX application running on a Tomcat server and the client access to this app by a browser. I want to create an file on the server side. How can i do that? Because at the moment if i use a path for example "/Users/username/Desktop" it will create the file on the client Desktop. I want to create this file on the server desktop. I'm using javaFX 2.2 on netbeans 7.2.1
Thanks in advance
I recommend the use of the library FileUpload. See too this other answer.

I'm very new on Java Web dev. On intellij Idea 14, I started a new project with plain Java, JSF support (no JavaEE, will add Spring later). Tomcat 7.0.59 as server. When I hit run on the IDE, firefox opens up and hits on 'http://localhost:8080/index.xhtml', it should display the hello world in index.xhtml that the IDE makes on new project, but the page just displays 'HTTP 404'.
I think the problem is path on the browser, how can I find the correct path and configure it on IDE deploy settings?, how can I debug on tomcat?, where can I start looking?
http://localhost:8080/index.xhtml is an incomplete address. Where is the context root? It should be the name of your project/webapplication, where you would have
"http://localhost:8080/{application-name}/index.xhtml".
Unless you've set your application to be the default tomcat application (which I highly doubt), you should have the name of your project in there in the URL
%CATALINA_HOME% is Tomcat install directory. Use %CATALINA_HOME%\logs to read Tomcat log for debugging.
When you create a new Java web project, It also means you are diving to Java EE (Enterprise Edition).

I am new to any JS framework and hence I am planning to build a SPA without using any Server Side Development using Ebmer.js. Since everything need to be done at the client side, can it be done without using node.Js which does provide some server side functionality ?
Basically I would like to build a login page functionality so that user can login only when they have provided correct credentials.
To build a SPA, you can go through different framework like jQuery Mobile, Sencha Touch which are AJAX based completely and needs a server. To simulate a server and to handle AJAX request you need to host a local server. Sencha has provided Sencha CMD 5.x which you can install in any system (Windows, MAC, Linux). After installing this software you just have to browse to the folder which you want to deploy on the server.
.
Open Command prompt or terminal,and type the command sencha web start.
After this you can access your application through a local server hosted on port:1841.
You will get an access to your file system as shown below.
And the result is like
I made a Java Web Application with Netbeans. I used JSF, PrimeFaces and the Glassfish Server. Now I want to put my application in a server but i just dont have idea of how to do that. I think fist of all have to install Glassfish in the server. How do I do that? The server i will be using has Windows Server 2008 Enterprise. Do I have to look for a .exe to install Glassfish? The same to do with Java? I have already done the connection to the SQL Server database so that part must work. So please explain me step by step what i have to have, how to install and configure everything and how to try if everything worked please.
Thanks for Your answers! :)
Depending on what your web application requires you will need to install more than just the glassfish server.
You need to install:
-Java jdk (required)
-Glassfish server (required)
-Database (if using one)
-Apache (if needed)
After you install everything, you need to deploy the war file of the application to the glassfish server. To do this you must first create a war file by 'cleaning and building' the app (option in netbeans). The war file will be located in one of the folders in the project.
Then you must log in to your glassfish admin console (located at http://localhost:4848 if run on localhost) and click on one of the options in the left menu that lets you manage the applications on the server. There will then be an option that lets you add war files to the server.
I am working about embedding a JavaFX GUI in a web application and I have this issue: the application launched standalone without using the jnlp file is faster than when it is launched by the web application using the jnlp file.
Some details:
The jvm is the last stable 1.7u40
All (also the application server) is running on my pc
All used jars are signed by a certificate I signed using a CA created by my self using keytool.
I set <update check="always" policy="always"/> on the jnlp file
The download policy of jars on jnlp file is lazy
On the web I found nothing useful or explaining this behaviour. My suspect is that the jnlp start my application and something more, I will do some check about this.
I am open to any suggestions.
Thank you
Update
I found that the JavaFX GUI is slow only if it is embedded in the web page: if I call from the web page dtjava.launch(that executes the jnlp standalone) instead of dtjava.embed(that embeds the GUI in the page) all seams to work quite good.
The question persists why is it slower embedded?
I want to build set of tools for my team and they will be as part of JavaFX application for which GUI will be build with help of SCENE BUILDER. I have seen everything that was available but I need an example how to embed this type of application on the server from which it can be invoked somehow. Please help with examples and links. I'd like to make it look as this one. http://download.oracle.com/otndocs/products/javafx/2.2/samples/Ensemble/index.html
Thank you.
Place a copy of the jar, jnlp and html file output by the NetBeans JavaFX project build or JavaFX packaging tools deploy command into a directory of your webserver, then access the html file in your browser.
For example, let's say you called your application MyPowerApp and netbeans output MyPowerApp.html and you wanted to deploy that to a local Tomcat server:
Download and install a copy of Tomcat
Copy the jar, jnlp and html file into tomcat's webapps/ROOT directory.
Start tomcat.
Access your application via http://localhost:8080/MyPowerApp.html
The applet will start automatically and you can click on the link to launch the application via WebStart.
To update the application just rebuild it in NetBeans, copy it over into the tomcat webapps/ROOT directory and refresh your browser link (no need to restart Tomcat).
In practice you will want to modify the html rather than use the generated html to embed either the applet or WebStart link somewhere on your website (you won't need both execution modes in a single page like the Netbeans generated sample).
You may need to sign your application if it refers to needs permissions outside of the jnlp application sandbox.
To get the application to fill a browser window like Ensemble, it's height and width need to be set to 100% and the HTML page template modified to not have any page margins (view source on the Ensemble page for a sample).
You can include your fxml in your application jar and load it from there or you can load it off your server relative to your application deployment directory.
