I have a JAR (java application), which I want to run on my iPad. Is that possible, How to do this? If possible through Appstore, (I know the process of Appstore and I have Apple Appstore account), please let me know is it possible to upload jar in Appstore and download from there?
No, it's not possible to run jar file into iOS or upload to App store. but Oracle ADF Mobile uses a native container that runs applications on both iOS and Android from a single source base. One part of that native container is a headless/lightweight JVM, but it's definitely not a .jar file

That's impossible. Apple doesn't support Java. Apple uses Objective-C as its main language. If I'm not mistaken, Safari on iOS doesn't support Java too so you can't run applet on iOS too.

I'm developing a system whose requires to capture user fingerprint. I have done this task using a desktop app in Java.
I need to do it via web using a form or dialog, but I have no idea how to do it. I want to avoid applets. Is there a way to place a button in HTML and capture a fingerprint?
I'm using verifinger sdk
UPDATE
I sent a message to Verifinger team and they sent me this:
Trial SDK package includes all the functionality, including VeriFinger Extended.
Before starting to implement these questions should be raised and answered:
Will your solution be able to interact with user's computer?
If you want your browser application to use client side fingerprint scanners and you want to use Neurotechnology components for it - you should write an applet (Java) or ActiveX component and then embed it to C# asp.net application (sorry we do not have sample for that). There are other ways of implementation but the applet is a general approach.
Will your solution be able to extract biometric templates on client side?
If you want your application to extract and/or do matching on client pc - you will have to use either an applet or ActiveX (in order to run code that references our libraries on clients pc). If you do not want to do that - you can capture an image (either with our components, or maybe just allowing client to select a file), upload it to the back-end (running C# ASP.NET, Java EE or even PHP), do processing there, return the results.
In general the Java Applet sample is a good place to start: you can use it for image capture and/or template extraction and write your own middleware (like enrollment to database or matching) on server (i.e. web services) and reference it from the client browser application.
SDK does include Abis sample java applet. It can be built with Maven running from command prompt this command: "mvn clean install -Papplet"
From SDK\samples\biometrics\java directory (if SDK 5.0 is used)
From SDK\samples\ (if SDK 4.5 is used)
Maven version 3.1.1 is recommended.
I hope it can be useful.
UPDATE 2
I did an applet which capture the fingerprints and passed them to a javascript function.
UPDATE 3
I released an example project to to this, explained in this post.
The Verifinger SDK contains components for creating stand-alone or web-based applications.
Available as a software development kit that allows development of stand-alone and Web-based solutions on Microsoft Windows, Linux, Mac OS X, iOS and Android platforms.
Is it possible to run java app (jar) in my android application? Because I need to create PDF, the problem is if I generate PDF in android, only can show with small image, if it contains large image in many pages, it will be error. So I think, I can generate PDF in java and then included to android app.
Concernig the mentiones app JBED:
Well honestly, I could not find any credible source for this tools JBED, so I would really be very cautious (e.g. who is the developer?)
In the manifestfile (in Androidmanifest.xml, where every app has to state what rights it needs to run, see How to view AndroidManifest.xml from APK file?) there are many rights mentioned (what could be necessary, as the app wants to run as an emulator), so a java application might want to send an SMS, record audio, take pictures and place calls -- so the emulator would need those rights as well.
But then the app also registers the "android.intent.action.BOOT_COMPLETED" event (i.e. autostart after boot) and this would go against every description of the tool.
Ah yeah and giveaway: The apk has a folder "certs" that has some (root-)certificates. But those are not the real certificates of the authorities, e.g. Versign. If one installs the app and by that those certificates the trust you might have in https-connections is lost because those who made the fake certificates can create own, false certificates that your phone would trust.
I assume (or am pretty sure) this is a spy tool, but I could be wrong. The (rare) testimonials that claim the tool ran perfectly will probably be the same person that posted the tool under a different name.

You can import java Third-party libraries into Android app, follow the steps here.
I am not sure whether it will work,but just try.
If your program is a console program, the answer is yes.
Install Jvdroid from Google play. Click terminal and then write this command: java -jar YourJarFileName.jar
The simplest way would be to some install terminal emulator and then install java and then you can run java apps on standard java. You can even install full Linux distro with x server without rooting the phone, then connect to it from x client and you have Linux desktop on android. Once I've even installed eclipse for java development on it and everything worked. I tested this setup last time in 2014, but I'm pretty sure you can do this nowadays as well. The app with Linux I get from play store as well app for the x client. The app I used back then was "Debian no ROOT" or smthg like this. You need to check what's currently available to make this setup in Google Play store according to your android version and your preferences. Last time I've checked there was a lot of different tools for this kind of task. Lastly I've even successfully installed TF and keras on my android phone using terminal emulator.
You can use JBED. JBED is an .apk Android application which run java games and app on your android Device. JBED is a java android emulator, by using
this application we can install .JAR/.JAD/Java/J2ME/MIDP app on android phones.
You can do it quite easily as there are many ways to run java apps on android. Specific application called Java Emulators can do it quite easily.
These are four most popular java emulators for android viz, JBED, PhoneME, Jblend and NetMite. These are arranged in order of their preference. You can use phoneme for non rooted device, however if your device is rooted try any of the remaining three applications.
I'm a beginner with java applets. I have developed few small desktop applications using core java ( Swing ). I need to build an applet which can do the following things -
Read a system file and modify it.
Create system file.
Execute a system command for setting some configuration of the client machine
Applet will download a file by running a system command. I need to check for the file size and plot download speed in graph.
Applet should run on all platforms ( MAC OSX, Linux, Windows, Android, IOS )
I have already developed this app using python and PyQT which is platform independent. So my app can be run on all platform but that requires PyQT and some dependencies to be installed on all platforms which is a difficult job. So we are opting for java applet to avoid dependent package installation and give more user friendliness and make the application platform independent.
I have already gone through the following link -
http://docs.oracle.com/javase/tutorial/deployment/applet/security.html
According to this link I need a privileged applet to do system related activities.
My Questions are -
Is is at all a good idea to use applets for what I need to implement?
How to make applets privileged?
Does applets work on Android or iOS? AFAIK, JRE is not available for these two platforms.
Can I go for JNLP API? Is that platform independent? I found some examples here - http://pscode.org/jws/api.html#fs
Thanks
Is is at all a good idea to use applets for what I need to implement?
No. Applets are a PITA to develop or maintain.
Do as advised by MadProgrammer and use a stand alone application.
How to make applets privileged?
Digitally sign them, then encourage the user to click OK when prompted.
Does applets work on Android or iOS?
No.
Can I go for JNLP API? Is that platform independent?
The JNLP API is available to desktop apps. and applets running in JSE (so again not iOS or Android).
There is no x-plat language that can cover all required platforms. I'd use Java for desktops & Android API for Android phones. I don't know what iOS is programmed in.
I am looking to write a web page that can load to it and run APK files. Something like a web control that can get an APK file url, load it and let the user interact with the app (No need in the whole android system, just the specified APK).
Is it possible? Is there anything like that in the market? Maybe a standalone open source emulator i can migrate to work on the web?
Short answer: no, but not fully impossible
Long answer: BlueStacks provides a raw and unstable emulation framework that is able to run single APKs without the full Android device emulation, but while it's not designed to run in a webpage, it actually executes as an ActiveX.
Here is my case, I have a window library + headers, but no source code. I want to use this lib on an android tablet. To make the porting effort minimal, I am thinking about three possibilities.
Android app + windows library.
But is this even possible?
java lib + windows lib + android app
I am not sure if I am correct. but I heard pure java app is not supported on Android. What I am planning is to make a java lib which links to that windows lib, then make a jar to include them, finally make a separate Android app using this jar.
Qt app + windows lib on android app
It is possible to run qt app on android. So if I create a standalone Qt App including that windows lib first. Run this Qt App on android device?
Please shed some light! Many thanks!
Br,

The short answer is "no, you cannot". Windows library (I assume it's a .dll or a .lib) is compiled on windows, with windows OS architecture in mind. That code would not be usable or even parseable on any other platform. It's like saying, "I have this wheel from my Mack truck, and I want to put it on my Mercedes C-class. How can I do it?"
If you don't have the source code for the lib, the you're out of luck. Moreover, even if you did, most likely it used some specific windows API that are not available on Android or any other OS, so you'd end up rewriting it anyway. As you have the header file, you are already part-way there, as you don't need to re-invent the interface.
