Question

I use using following codes to open a dialog box in my current project as i have read about controlfx and its awesome dialogbox so i have used its code in my project but it gives error and i don't know why?

 Dialogs.create()
        .owner(SchoolManagement2.stage1)
        .title("Information Dialog")
        .masthead("Look, an Information Dialog")
        .message("I have a great message for you!")
        .showInformation();

I have added following jar

Hey man i used an warning, and works i wanted

Alert alert = new Alert(AlertType.WARNING);

        alert.setTitle("Warning");
        alert.setHeaderText("Look, a Warning Dialog");
        alert.setContentText("your content text!");
        alert.showAndWait();

Answer 2

i'm working with Netbeans and Mac OS ML.

I have the same problem, i can't run my program from Netbeans. But if i run the .jar file out of Netbeans, this works fine :)

I see that in Netbeans the JRE setted is 1.8.11, i can't set the JRE 1.8.20 installed into my machine.

Edit: I solved the issue, in my cas: editing the Netbeans config file

• On Mac OS X: Ctrl-click /Applications/NetBeans/NetBeans IDE 6.5.app in the Finder and choose 'show package contents', then browse to /Applications/NetBeans/NetBeans\ IDE\ 6.5.app/Contents/Resources/NetBeans/etc/netbeans.conf.
• On Windows: C:\Program Files\Netbeans\etc\netbeans.conf
• On Linux the installer lets the user choose where you want to install NetBeans. You may find it under /home/yourname/netbeans/etc/netbeans.conf or /opt/netbeans/etc/netbeans.conf.

See: http://wiki.netbeans.org/FaqNetbeansConf

We need replace the current jdk by jdk1.8.0_20 in this line: netbeans_jdkhome="/Library/Java/JavaVirtualMachines/jdk1.8.0_11.jdk/Contents/Home"

For security, after do that, do a copy of netbeans.conf file :)
