Motorola Mk3000 application development - java

Does anyone have experience developing an application for Motorola MK3000, been reading the manuals and browing the web but can't seem to find a good guide. I feel like this is my last resort. I have a background in c++ and java, anyone can help me? or point me to a good (not confusing) guide? Thanks in advance...
Edit:
Sorry forgot to write what kind of app. I would like to create a bar code scanner that will fetch the image and other infos from server with the corresponding ID, kinda like the one they use in malls to find the item price.

There are similar topics if you search for them. E.g:
How to integrate the scan barcode option on my WinCE application?
If you need more information feel free to ask.

Java JADE: Network connection

I'm a beginner on JADE and I need some help with a problem. I have an application which is a Seller and a Buyer buy books. Actually, the seller will add some books and the buyer could search for one to buy it and this is made by using JADE framework.
Now my question is: Is there any possibility to make this application online? For example, if I am a seller on another computer, how could I add some book to be able one buyer see them from other computer? And I can have any number of seller and buyers.
I've heard about JadeGateway and GatewayAgent and some stuff with webpages...
So if anyone knows how can I do this kind of connection on internet(preferably without some webpages and automatically application) please explain me, or sent me an simple tutorial.
HERE it's my code, I could not post it here because it's too big. If anyone could give me and idea how to do this based on my code will be perfect, if now... Any kind of advice or tutorial will be great :).

To make a decent to high quality mobile version of my website?

I'm new to Stack Overflow, but I asked a question last night regarding some code and it was answered just over night. I'm very glad I finally signed up here. Anyway, on to my question...
I need to make a mobile version of my website [www.famebyname.us]
I am using Dreamweaver CS6, and my intention with the domain is to turn it into an online nightclub/chat/music type thing. It has a long way to go, but it's basic for now and can do for basic communication. I'd like to make a mobile version of it. But instead of just going forth with that, I thought I'd ask here if anyone could share some experience designing mobile sites [IE button sizes, content alignment, and above all how to keep the smartchatbox working for the mobile device while being size friendly.]
On a site note I'm going to be using the java code below to redirect users with a screen size under 699px to the mobile version aif anyone has any better recommendation for this type of redirection, I'm open to new ideas.
<!--if (screen.width <= 699) { document.location = "mobile.html"; } //-->
Thanks in advance.
Instead of doing all the coding for mobile site. Why not use the framework? There are many frameworks out there that support mobile friendly site. All you need to do is setup files and start calling them in div tags as classes and it will do all by itself. You would need to understand tho how it works.
Checkout this frameworks :
Bootstrap
Foundation
Ui kit
Semantic UI
Dont reinvent the wheel when you such powerful frameworks to help you.

Sign in with MySite

I want users will be able to sign in other sites using their accounts on my site. It should be something like "Sign in with Google". Can you advice me any libraries or frameworks?
I thought about how to run my site as openid provider but I really don't understand it... Can you help me? I'm just a beginner in programming. I using java.
Thanks. And sorry for my english.
If you're just beginning to program then this might be a bit over your head. But if you're still willing to try, then take a look at tutorials regarding writing an open id provider (like here or here ).
Some helpful libraries are listed here and here.
It is important for you to understand how open id works and one good place to start is this google presentation.

AJAX Chat How to add voice with Java?

Ok so I use Ajax Chat (http://sourceforge.net/projects/ajax-chat/) and it is a great chat script. I use the MyBB Integrated version and all is well. What I am wanting to know is how I could add voice capabilities.
Basically each channel would be similar to a Yahoo chat room and have a talk button. This way someone could talk and the rest of the room could hear.
Flash is NOT an option, and I tried RED5 with it and the results were terrible. Bad quality, couldnt hear half of the time, etc.
I have searched and searched and searched and all I find is calling, IP-to-IP, etc.
I would like to do this in JAVA if possible which is not one of my best languages. I do have root access to my server and it is linux (CentOS). So what I really need is a point in the right direction on how to do this.
Thanks in advance.
The best way to do this is to use the Java Speech API. You can find out more information about this at this site. This question was already answered actually in this link.

Streaming audio from online radio

I've had a break from programming from a while and slowly but surely I'm coming back into it. I've been looking for a way to stream (and play) audio from an online radiostation (such as FearFM). I've been looking for duplicates and similar questions on Stackoverflow but didn't really found something usefull. I've also looked at Google, but it gives me the impression that the audio support at java is a bit a dark space.
Could anyone point me a direction on how to approach this? Libraries, examples, descriptions.. everything would be appreciated :)
Thanks in advance,
wvd
If you want to work with media in a Java GUI you could check if JavaFX suppports what you need:
