I have a Neatbeans application, that works well and runs well so I want to move it into Android. So I am taking code snippets and moving it into Eclipse, and into a default made droid class. (which compiles, loads, and displays on the virtual device)
The problem, is that a few things that used to "import" into Netbeans, won't in Eclipse, or I am just doing it wrong, not sure.
Usually in Neatbeans I hit "import such and such class" and then it all compiles fine and no red errors appear in the code. In Eclipse, it is not giving any import option to some features, examples are..
DefaultModelList
HTMLUnitDriver/WebDriver (Selenium's program)
JOptionPane
And I am guessing some more will eventually pop up in the future.
Does Eclipse not support those options or something? Or is it Android that does not support those options?
Can someone tell me how to work around those issues, with their respective problems please?
The program itself is a mobile chat application, that will basically be a mobile version, of a chat that already exists on the web. Pulls chat feed data, lets you post chats back; basically the same thing as the chat on the website, but accessible from your smartphone.
Your problem is not with NetBeans vs. Eclipse. It sounds like your app uses the Java UI Framework Swing, from which you have JOptionPane. Swing is not available under Android, and anything that uses Swing will have to be extensively recoded to use the native Android UI instead.
Your app may use other libraries that aren't available in Android, as well.
Eclipse does support those options (press ctrl-shift-o). The problem is most likely the transition to Android -- lots of items change names. The Android native item to use is not JSpinner but Spinner, etc.
Also: In Android most GUI work is done with layout .xml files, a bit different than plain Java programming.
TLDR: you're conflating multiple issues. Eclipse can even import a Netbeans Project directly.
Is Eclipse a strong requirement for you? If you love NetBeans and everything is working, why not to continue with it? I believe you can develop for Android in NetBeans too...

I am kind of confused as i am using Eclipse Luna in my kind of big project, and i was using JavaFX fine, for now.
I am trying to implement a Process Dialog as shown in here
And here is a tricky part, my eclipse does not recognize nor know what to do with those few badly importat lines
Dialogs.create()
.owner(stage)
.title("Progress Dialog")
.masthead("Searching for friends")
.showWorkerProgress(service);
The first word in this code gets underlined and a mysterious
Dialogs cannot be resolved
show up as i hover above it..
I can not understand this matter as i use a lot of JavaFX in this project, and i did not have any issues with any part. Alerts, windows and all stuff like that works fine, only this thing is kind of strange for me.
Also, i do use JavaFX ver 8.0.45-b11, and it disturbs me as somewhere i found that
JavaFX has never had a dialogs API, which has always seemed to be a
glaring omission – but no more! It has (finally!!!) been decided that
JavaFX 8u40 will be the first release that will include a dialogs API.
Could someone please tell me if there is any mysterious thing that one must do to use this JavaFX Dialogs API?
No need to use 3rd party dialogs going forward. Learn how to use the dialogs native to jdk8u40+ from this JavaFX Dialogs page.
I am working on a primitive online game client that I wrote as a Java Swing application. My problem is that potential users refuse to download and run any unfamiliar executable. I want my game to be reach as many people as possible and users fear that the executable might contain a virus. That is why I would like to embed the game client into my web page instead. How would you turn this Java executable code (liked below) into an applet?
Thus far I have a main which makes the initial connection to the game server...
https://dl.dropboxusercontent.com/u/214507961/Main.java
A Java Swing GUI that I made with the Netbeans GUI builder...
https://dl.dropboxusercontent.com/u/214507961/GUI.form
Object input/output streams connected to my game/web server...
https://dl.dropboxusercontent.com/u/214507961/Clients_Input.java
https://dl.dropboxusercontent.com/u/214507961/Clients_Output.java
And some buffered images for graphics...
https://dl.dropboxusercontent.com/u/214507961/Image_Repo.java
Note that in future development, I would like to replace much of the primitive looking 2D Swing GUI with content rendered with the Lightweight Java Game Library or some other higher-level video game graphics specific library to make the game look better.
Given that information, what is the best way to make this Java application into an embed-able (applet)? Describe your method and reasoning in such a way that even a college freshman could follow.
Note: Following the advice below, I have tried using WebStart, but I still get an intimidating warning:
Update:
I am in the process of refactoring my code so that the top level container is a JPanel.
I have tried making "GUI" extend JPanel and changing the "gamewindow" from a JFrame into a JPanel.
Modified Main:
https://dl.dropboxusercontent.com/u/214507961/Panel_Top_Level_Container/Main.java
Modified GUI:
https://dl.dropboxusercontent.com/u/214507961/Panel_Top_Level_Container/GUI.java
Despite the changes, Netbeans will not allow this program to run with Java Web Start.
When I enable WebStart and Build/Clean, Netbeans creates two files:
I then clicked Build/Clean and it generated two files:
master-application.jnlp
https://dl.dropboxusercontent.com/u/214507961/Panel_Top_Level_Container/master-application.jnlp
preview-application.html
https://dl.dropboxusercontent.com/u/214507961/Panel_Top_Level_Container/preview-application.html
but no JAR file.
Still working on it. AI moved the remainder of this question to:
Why can't I get Netbeans with Java Web Start enabled to work on my executable?
At this point I'm so tired of putting up with the security hassles and see little to no way to get around certification warnings without paying. I have decided that it would probably be better to just re-write the entire client in HTML5 and javascript.
The basic concept is to build your app (GUI basicly) without using applet specific technologies (like commmunication with web page via JS etc.) and with JPanel as a top level container insteed of of JFrame (Window would be accceptable too, as JApplet extends Window). If you do so, that you will be able to deploy the same code as standalone application and via JNLP as applet.
The digital signature could not be verified by a trusted source.
This is caused by the app. being 'self signed' by a digital certificate we generate ourselves using the SDK tools. Security was increased recently so that 'self signed' apps. get that scary warning. This has been discussed extensively across SO in recent times.
Try looking at the posts under applet+security for details.
Redo the client using HTML5 and Javascript so that you don't run into any prompts or security warnings.
I'm building a Java application using NetBeans 7.0. The app is intended for use on Windows, so I guess the tool I'm really making most use of is Java Swing (for the cool, nifty screen elements).
My question relates to NetBeans' process of creating the various project types. The application I'm building is based on the "Java Desktop Application" template (?). My problem is that there seems to be a nice load of bloat built into that, and I can't figure out how to remove most of it without blowing up the app.
As a test, I created a "Java Application"project, but this has the opposite problem -- there's absolutely nothing built into the code, and I can figure out how to add anything. Specifically, a Java Desktop Application project created in NetBeans give me the ability to directly edit the screen layout like in Visual Studio. However, a Java Application does not appear to have this capability, I have no idea how (or even if) this can be addressed.
If I could start with a no-frills Java application, and add some capability to edit its layout and control the function of the screen elements (i.e. make it a windows application, I think), that would be just about perfect.
Does anybody have a suggestion for a minimal, but functional NetBeans application start point??
Thanks,
R.
If you start with a plain Java Application then as you realize you start with a bare bones type application. To add a GUI you can add New>JFRame Form. It adds a class that extends JFrame and Netbeans will recognize that it should open it in the visual editor for you.
So I built a program in Java using swing for the interface and i didn't realize how difficult it would be to convert it to be used as an android application. Is there any way for me to easily convert or rebuilt the program to be sold in the android market place? If not can anyone point me toward any resources to help build a android.
I did the same thing awhile back. Although there is no program out there that I know of to convert it directly. The Java code and the android code are very similar. Since android doesn't use swing's UI it uses XML based UI. once you get the UI functions of the android app down your Java code can be easily imported.
I am working on converting my Java app into an android app now. Most of my classes imported with no problem.
AjaxSwing allows to convert Swing applications and use them directly on android or ipad, see http://www.creamtec.com/products/ajaxswing/solutions/java_swing_ui_on_ipad.html
What I would do is that I would build the UI in XML, then I give the items an ID and reference to it in Java, and then I'll trigger everything by button clicks so what one button does in your swing layout does the same on android. You can't copy/paste it.
swing UI was meant for desktops and pc's but for
android you have to use Xml then you can keep your java codes as they are in the various activities
then use your event handling skills to trigger them
Open the project's properties
Select Java Build Path
Select Libraries tab
From there you can Add External Jars and you can use swing layout
For all of you android devs out there that have the Android simulator running on your comp, you know that there are a few built in apps that are already installed on your 'phone'. I had an idea for an app that would utilize a function that is already being done in the spare parts app that comes already installed.
I went on to the android developer site, dug through the source code files, and found the spare parts app, and am now trying to set it up so that running it from eclipse on my machine actually runs the app in the simulator. In other words, I want to be able to make changes to and adjust some of the things in that app for my own needs. But it won't compile, because of a number of different errors.
How do I get that source code running on my local machine? Is there some special trick that I just dont know about? I thought that if I could get the source code than the rest would be easy, but it isn't being too easy.
Not knowing what the error is, it is hard to say. But there are some tricks. First, you want the entire spare parts app in Eclipse, not just the code you are interested in running. Second, right click on your project, and go down to the "Android Tools" menu. Then click on "Fix Project Properties". Do a clean on your project and hopefully that will help.
