i have created simple applet program and hosted in tomcat server.
it works good in PC's browsers. but when i try to load that page in smart phones (android, iphone ) could not work.
Does the applet supports on smartphones ?
or is there any additional configurations that i need to do ?
Is there any option to install java plugin on smartphones(android , iphone) browsers?
I think now most of smartphone not support applet.
But if you use framework like phonegap then may be you can get exact GUI.
And yes Android has not JVM so android can not run your applet contain class file.
And iphone also not support JAVA. Iphone support only Objective-C.

I have installed eclipse phonegap plugin and I am easily able to make applications for android. However I want to make application for any other platform like bada, tizen , blackberry, etc. But when I create new Phonegap project, it doesn't show any option for choosing platform. It directly takes me to android. Is there any way that I can use this plugin for developing for other platforms.
I have googled a lot but nothing found relevant.
Probably you may be interested in Titanium. Latest version supports (check beta) Tizen and Blackberry 10 as well as Android and iPhone. With it you will be able use javascript for mobile application development. Also it creates "native" application instead of html if possible.
And forgot Bada. It`s gone.
I have an android project that targets Android 2.2 (developing in Eclipse). Exporting the android project to the Droid Incredible works perfectly. Is it possible to export the project to a file suitable for installing on an iphone? I know that most iPhone apps are developed using xCode, but I'm not sure if xCode packages into a .apk or other file format that's equivalent.
Thanks in advance.
Only if you write or port your own complete Dalvik VM (in Objective C or Javascript), plus developing the runtime support needed for any and all API calls that your app uses, and bundling all that with your app, as that would be the only way to run a regular Android project on an iPhone.
A non-trivial amount of work.
Completely rewriting the app in Objective C and Cocoa Touch would be magnitudes easier.
Not even remotely possible. Android and iOS are completely different environments. There are a few frameworks for developing applications that'll run on either, but the results often end up looking kind of weird on both platforms.
You cannot export an Android application and run it in an iPhone because the hardware/software stacks/APIs/etc. are different.
However, if you build an application using for instance PhoneGap (a HTML5 based application framework), it is possible to deploy it on different mobile platforms.
If you feel curious about multi-platform mobile frameworks (Android/iPhone) you may find this thread interesting.
I have created a simple web plug-in to write data to file system. This works as expected on a mac Safari. Here i have to manually place the plug-in on to the /Library/Internet Plug-Ins folder. My question is there a way to find if the plug-in is not present through JavaScript and if it is not then download and install the same. I also would like to know if the same can be done on mobile Safari running on ios4 devices?
Obviously you can not load Plugins of any kind in Safari on the iOS device. This is the main reason Flash does not exist on iOS.
On the Mac you can do that. But you need to create the plugin in C++ and for each platform independently.
If you code the plugin correctly, it should be possible to "detect" it using JavaScript. I highly doubt you can download it automatically, though. This would pose a very large security hole for every user.
Recently we are going to develop some products on mobile phone (specially for 3g). There are many platforms about mobile phones: iPhone OS, Symbian, Blackberry's. If I want to develop a product, should I use Java or write every program for the main platforms?
Particular one question for iPhone development: are there many Java programs on iPhone? Most iphone app I've seen are developed by their own xCode.
I need some guidance on how to do coding for mobiles correctly.
All these platforms are completely different beasts as in the old days. About symbian, (which I am most familiar with) you can use Qt for quality native applications. Native api is confusing so avoid it where possible. If your application is simple, you can even get away with python.
In short, use the language which you are most productive available for each platform. Their apis are wildly different anyway. Language choice doesn't matter as much as the choice of platforms you are supporting.
Java is not available for use on the iPhone; you can use Objective-C, C and C++ to develop iPhone applications.
There is currently no Java for iPhone, so you need to develop separately for iPhone in objective C.
Alternatively you can create application which runs in web browser, it'll be available on all platforms, but not every application is suitable for web.
Have you considered you using web technologies?
There are a couple of cross platform tool kits for iPhone and Android. They work in the same fashion as Adobe Air. Allowing you to make HTML/JS based web app and run it as native code in the browser.
Titanium Mobile (Android & iPhone) HTML/CSS/JS
Corona iPhone Only via Lua
Palm's Web OS is also based on web technologies.
Finally the old guard, Symbian Provides a Web Widgets system, that works in on all handsets with 9.2 fp 2 installed (n95,e72, n97 etc.) The api supports some hardware functionality.
The only one left out in the cold is Windows Mobile. There is some 3rd party support in the form of Web Widgets by torch mobile
It's currently limited to iPhone, BlackBerry, and Android (and possibly WinMo) but you may want to check out the open source project called PhoneGap. I think it is basically just a native wrapper around the built in web browser for each device, but it does expose some functionality not normally available in that environment such as geolocation, accelerometer, sound, etc.
Exists an universal phone developement language?
I mean, for example, php or java or whatever
Edit : We have to develop a few phone applicatons, and we are looking for the best reusable language in differents devices (Blackberry, iPhone, Motorola, etc)
Java is as close as you'll come, but it's no where near universal (iPhone doesn't support it!)
Since iPhone's language isn't used by anything else either, it's pretty much a given that you won't find a universal solution.
Rhodes by Rhomobile is a Ruby framework for building cross-platform phone applications. It allows you to build a single application that works on all major smartphones: iPhone, BlackBerry, Windows Mobile, Symbian and Android. (The only obvious omissions seem to be OpenMoko and PalmOS/webOS, but all the phones you listed are supported.)
The way Rhodes works, is that you write your application in Ruby and your UI in HTML. A Ruby implementation, the Rhodes framework itself, your application scripts and your HTML files then get packaged up into what looks to the phone's operating system like a single native application. Rhodes then runs a webserver inside of the phone and serves the application from there, using the phone's builtin web browser UI component and a JavaScript UI library for making the web app look like a native app. (E.g. iUI for the iPhone.)
There was a nice introduction to Rhodes (with live coding) by the Rhomobile CEO at the Mountain West RubyConf 2009, the video is available at the Confreaks website.
Java (more specifically J2ME) will work on most phones. Googles Android and Blackberry development involves Java too. On Symbian-phones you can develop in C and there is an interpreter for python. If you are aiming for the iPhone market you have to stick to Objective-C and the Cocoa Touch framework.
There is no universal language, nor universal runtime that is supported by all of the major platforms. Two major players are Java on J2ME, BlackBerry and Android devices and Objective-C on the iPhone.
You might want to check out Symbian phone OS, it is intended as a common OS originally a joint collaboration between Nokia, Motorla and Ericsson. see: www.symbian.org/index.php
HTML + Javascript + CSS
PhoneGap!
It is the only cross platform mobile framework that I know of. Has feature support for iPhone, Android and Blackberry

Well!!! Most of the phones support java. What are you trying to do? Learn a new language?
Java is probably the closest you're going to find.
Even if you can do it, what good does it do to write a mediocre application that doesn't really take full advantage of whatever device it is on?
Bite the bullet and choose to do great implementations on a selected subset of mobile platforms.
