Oracle reflects on starting an app store of JavaFx?

Similar to stores mobile app.

Only to read this post if you are really interested in deployment of JavaFX. What follows is more free-thinking hikes than anything else (sorry if this is kind of off-topic since the original post).

I get where Jeff is coming from here.

The statement "packaging App is a prohibitively expensive process for young and beginner developers--Oracle could make this easy again" is true. There was some progress in NetBeans to make the process pretty simple packaging, but which requires that you apply a NetBeans project which is not ideal. The JavaFX deployment guide is complete, but surprisingly elaborate and complex. Ant based build tasks and the deployment of browser based, which form a large part of the deployment guide, are both a bit archaic now. For those using Gradle or Maven there is third-party build such plugins Plugin Maven JavaFX and Gradle Plugin JavaFX - these things can help a lot, if you use those build tools. The simple fact of having JavaFX on the class path by default Java for Java 8 helps to solve many problems of generation and deployment, what new developers.

> There is enough information in a JNLP for Oracle to do it for any platform

I'm not completely sold on JNLP is the main mechanism of definition of package or Web Start is a primary deployment platform. JNLP ends up being incomplete or a nice abstraction that leak. The history of JNLP and Webstart is littered with good ideas not implemented or maintained (e.g. implementations have bugs and quirks). Microsoft Appx packaging format contains additional items such as rotation preferences, definition of lock screen and showcase related details, which could be applied to modern devices. AppX clearly resembles she modeled some of it is of ideas of JNLP and the associated JNLP services. Maybe with the right amount of effort and focus JNLP could make desirable, but it seemed like that for a long time and never quite there.

On the deployment plan, the main competition for JavaFX apps are native applications and HTML applications - in order to succeed, deployment for JavaFX applications should be as simple as those, everything else is a failure.

Packing a JavaFX application as a native application that can be deployed on an app store means that JavaFX and native applications are on a nice playground. The only thing is to make sure that the JavaFX application can easily make enough use of the features native app (for example, the customizable installers, office integration, the icons appropriate, etc.). Existing packaging features for JavaFX app get pretty close to this ideal (especially if complete you some of the logic of the 3rd party JavaFX Gradle tool that will do the conversions of icon as appropriate - which are a pain in the neck for native applications).

Competing with the HTML is more problematic, because its extreme accessibility, universal client, deployment patterns well-established and simple links and deep links have long been some of the main advantages of HTML on almost all other types of software. In addition, existing customers of HTML are positively hostile to the traditional technical deployment Java applets or built-in browser applications (with reason in some cases) web-based.

A thought I had is that could use a service such as Amazon app streaming , so everything you do is upload your application to a cloud based server and everyone can access the application via a browser, just as they do a web application. To a user, they can not really say that there is a JavaFX application and there is nothing to install. If done correctly, all required that a user is a browser that has the ability to canvas and websocket (and a tip big enough and fast enough to make the transfer of data and offset size isn't a problem). You need a pretty Beefy Server (CPU and GPU) wise to manage the rendering of the interface of many users - but cloud computing user ceases to be cheaper. When I get some time (which is as ever), I really want to prototype this approach to see the feasibility (or not) it is.

> Oracle needs to have a site that sells applications Java Web Start related in form of packages from a native application for the selected platform... they could manage the platform code signing and, ideally, issue certificates themselves, like Apple

One of the problems with the current native packaging techniques is that they require the user to run the native OS target to complete the packaging.

I think that there is a place where Oracle or a 3rd party could turn a cloud of basic service (with appropriate front-end GUI) to which developers can submit JavaFX applications and service can open packaging of the application for deployment platforms selected (including the signature, verification, staging and possibly accommodation for webgame app deployments). I guess the signature part might be a bit of a problem because it requires a private key, but a rich client could handle this part so that the relevant private key could be generated on the client and not transferred to the cloud. For free software, the cloud service could shoot automatically in a github or bitbucket repository, so => consignment of your code and a few seconds later there is an appropriate set of native clients hosted to download as well as a listening server update application anyone can navigate to and use with no installation.

> I think having a good console tool and IDE/maven/gradle integration is more practical and easy fare

Maybe you could do a large part of the above with a console tool. There is an existing console tool supplied with JavaFX, it's the javafxpackager, but its interface is a bit heavy as it tries to do so much. If a console tool have been used, a System snap-in (such as the Ceylon command-line tool), is probably the way to go, that way we can community plugins and extensions to allow the deployment tool doing additional things. It is difficult to advocate a console tool however, because there are already tools to build extensible plugin in the Java world such as Maven and Gradle which are (possibly) better suited to this task and most well-established. The git model on which is based the Ceylon command-line tool has proved in the past with the two access nice command line traditional and cloud rich interfaces such as github being built on the basic functions of git.

> It could also have a JavaBrowser.app, to manage the applets.

It's something like WebFX - not sure what would be the adoption of such a model of deployment, but it is technically possible (even a reality really). Only handles WebFX scripted JavaFX applications (as far as I know) but you could extend to run applets or embedded apps.

----

Anyway, the best news around Java Client package is Danno Ferrin (creator of the Gradle Plugin JavaFX) working on it. He has created a google for JavaFX packaging discussion group, so ping it if you are interested in the subject.

When App Store starting spinning wheel

I often get a spinning wheel when starting the App Store on my iMac. It's still, sometimes accidents application after some time. On the internet I found some solutions (killing the app, removing plist files, doing a NVRAM reset,...). It helps, but the second time I start the App Store to the spinning wheel is back. It's annoying because I want to install the updates and I don't want to delete the plist files and make a NVRAM reset each time. Maybe someone knows a more permanent solution?

Start Safe Mode removes the system caches that can help.

Upper left corner of your screen, click on the Apple  > Shut Down.

After your Mac stops, wait 10 seconds, then press the power button.

As soon as you hear the startup tone, hold down the SHIFT key. You must press the SHIFT key as soon as possible once you hear the startup tone, but not before.

Release the SHIFT key when you see the gray Apple logo and progress indicator.

Once you are in Mode without failure, return to the menu Apple . In the drop-down list, click: reboot

Then launch the App Store then try your updates.

Please test after taking each of the steps that you have not already tried it. Stop when the problem is resolved. Back up all data before making any changes.

Sometimes, the cause of the problem may be an Apple network, whereby failure cases none of the steps below will have no effect. You just have to wait for the failure be fixed. This should rarely, if ever, take more than a few hours.

Step 1

Connect to the App Store by selecting Sign In in the Store menu. If you are already connected, disconnect and then reconnect.

Step 2

Log off or restart the computer.

Step 3

Remove or disable 'LittleSnitch' or any other third party software like that blocks outbound connections to network in accordance with the instructions of the developer.

Step 4

Start in safe mode and log on to the account of the problem.

Note: If FileVault is enabled in OS X 10.9 or an earlier version, or if a firmware password is defined, or if the boot volume is a software RAID, you can not do this. Ask for additional instructions.

Safe mode is much slower to boot and run as normal, with limited graphics performance, and some things work at all, including an audio output and a Wi - Fi connection on some models. The next normal boot can also be a bit slow.

The login screen is displayed even if you usually connect automatically. You need your password to log on. If you have forgotten the password, you will have to reset it before you begin.

After testing, restart as usual (not in safe mode).

Step 5

If possible, connect to a different network and test.

Step 6

Reset the NVRAM.

App Store starts do not. Just blinks and falls

Hello

I've updated to Windows Pro 8.1 today. Windows 8 Pro. I updated via the App Store.

After installing, everything works well except for the App Store. When I click it (regardless of whether it is by the start screen or in the list of Apps) begins the application store - the green screen with the logo of the store. And after a second or seconds (depends) it's just minimazes. It will not load. It has not been loaded since the update.

After I click on the App Store reduced it shows the screen green with the logo of a second (or seconds) and reduced again. Closing and re-opening do not help. The pattern is repeated.

Reboot PC (several times) does not help.

All Windows updates are installed. No new are available (I checked manually).

No update in the App Store Windows were pending before upgrade to Windows 8.1.

I tried to disable Firewall (I use Eset Smart Security 6 antivirus.). Did not help.

I would appreciate your help.

How Windows App Store does not start (I tried "everything")

It's just my story. The OP may be completely different.

The research on the net I saw that many people suffer the problem described, that is to say the App Store apps and win 8 crashing. So I was hoping that a solution could be found.

That's all just amazing! I have the same problem with exactly the same results. It doesn't seem to be a solution without refreshing. I can't access the Windows store, I'm stuck with Windows 8 and cannot move to 8.1. I tried several times to pass to 8.1 when I could go to the store, but it failed every time with an error code OxC1900101-Ox20017. Any suggestions as to what this error is and how to fix it. So, I seem to be stuck with Windows 8 until Windows 9 comes out. I am not convinced that this will present all kinds of new questions. I can't understand why Microsoft cannot fix this easily because he seems to have been going on for at least a year. I hate the idea of how much time I wasted on this. My only saving grace is that I can return to my laptop with Windows 7... happiness!

connected to internet but app store don't think so just upgraded to 8.1

Try to update an app but the AppStore do not think that I am connected to the internet when I am, everything, Google Mail, search etc. working fine, just improved 8 to 8.1 is relevant thar?

Bertieandrose,

Welcome to the HP Forum.

The upgrade to Windows 8.1 could have mistaken your app Store of Windows.

Try / review
- Create a Restore Point: create a restore - Win7 Point OR create a restore point Win8
- Ensure that all of your Windows updates for Windows 8.1 news have been installed. This is a must-do. Even if you're usually afraid of the presence of updates of Windows running on your computer, this isn't the time to be shy - after an upgrade to the version of the operating system, you run the updates.
NOTES:
1. If you do not like to be surprised, set Windows Updates to Notify instead of auto. In this way, that you can click on the updates of Windows when you are ready to check / install updates, see the list of updates advance, create your own "pre update" Restore Point, and then install the updates when you are ready to do.
2. Do not install any optional updates, unless you know what you're doing and you really need. Most people do not require or need optional updates on their computer.
- Reset your Windows Application Store:
Windows key (Opens the start screen) > anywhere type wsreset >

Right click on wsreset > select run as administrator

Reboot / restart the computer and log in, if you like
