First MIDlet help

Hello,
I'm brand new to J2ME (and still a beginning programmer), and I was hoping to get some assistance or some resources for my current issue.
I have a very small, very simple MIDlet that I am trying to get to run on my Samsung SGH-A707 (also known as the Samsung Sync).
The MIDlet runs in the emulator provided in the Wireless Toolkit 2.5.1. I've used the toolkit to package the MIDlet and created the .jar and .jad files.
The issue is when I move it to the phone. Using Bluetooth, I''ve pushed the .jad, the .jar, .mf, all to the phone. I even tried the raw .class file just as an option. Whenever I try to run any of these, the phone gives me "Unsupported file type".
I've read that Cingular has locked the phone's capabilities and you can't simply move java files to the phone, but that you have to use OTA provisioning. I found www.euploader.com, a site that allows you to upload your files for free, and then download them to your phone over WAP. I can surf with my phone to the site to download the file, but when I try to actually download the file, the phone tells me "Incorrect description", and I am unable to download it.
I've been researching this problem for a few days now and I can't seem to find any references to either of these error messages.
Am I still going about this the wrong way, trying to get my MIDlet on the phone? Did I miss a step? Does anyone have other suggestions to get the program on the phone?
I appreciate any answers and resources anyone can present.

Almost nothing concrete to check in descriptor, only its format.
It should contain property pairs:
name1: value1
name2: value2
etc.
Only one idea also, check the following items:
MicroEdition-Configuration: CLDC-1.1
MicroEdition-Profile: MIDP-2.1
Check, if this ClDC and MIDP versions are supported by your target device.
If they are not - set acceptable for device versions of libraries in build configurations of your project in WTK.
If all is OK, Emulator does successfully upload and run the package, versions of libraries are OK too, then it's only possible to report bug to producer of your phone device.
Regards.

My parents ended up with my contacts on their Iphone when updating their Iphone for the first time, help?!

Ok, my family uses one Apple Account and we share music and stuff but when me and my sibling got Iphones like my parents, it got confusing. I was the first to sync my Iphone 4s into the computer and the Apple ID is put under my name. All of my Apps, contacts etc are on the account. But my parents decided to update their phone. Theirs is an Iphone 4s, like mine but they haven't updated it to IOS 7 since they got it so they plugged their phone into the computer syncing my information while deleting THEIR information. I think the computer thought it was MY phone and kicked out my parents information in the process. I don't know what to do, they have my contacts, pictures, apps, games, email accounts and TEXT MESSAGES. We have different phone numbers but how is that possible? I don't get it. Anyway, it would be nice to solve this problem because my sibling wants to update his own phone. If you guys have the answer, just post it up on here That would help alot!! Thank you!
<Email Edited by Host>

Go to Settings>General>Passcode Lock>tap Turn Passcode Lock Off, enter your "pin".
Edit: Are you saying you are getting a prompt for your email pin, or are you talking about the passcode lock that appears when you turn the phone on?

Broken on the first day HELP

hello have just bought a iphone 5 and in the first day the lock button has jammed down what can i do please HELP many thanks declan

It's under warranty. Take it back.

JAX-WS contract first solution help needed

Hi,
I am trying to create a bunch of web services using jax-ws which I will deploy on Jboss. I would like to create xml schemas and wsdl files before I create my solution because I want a clearer contract betweent client and server that is not defined by the server code.
I have managed to create an xml schema and generated the message files. I also created a wsdl file and implemented a service endpoint which refers to the wsdl file.
My problem now is that I cannot seem to get the mapping (marshalling) to the Java objects to work correctly. When I create a simple client that calls the service defined in the wsdl file I have managed to get the request to map to the webmethod in my endpoint. But I cannot seem to figure out how to get my message validated against the schema, which means that I can call the method with any type of request without getting an error message. This is also true for the return object. The solution doesn't seem to care whether I return a string or the object defined in the wsdl file.
I created my solution as a "regular" jar which I deploy on Jboss.
@Stateless
@WebService(name = "Test", portName = "TestPort", targetNamespace = "http://www.company.com/test-service/", wsdlLocation = "META-INF/wsdl/test-service.wsdl")
@SOAPBinding(parameterStyle = SOAPBinding.ParameterStyle.BARE)
public class TestBean {
     @WebMethod(operationName = "PerformOperation")
     public Response newOperation(Request request) {
          return response;
}Could you give me some tips and advice to help me finish my solution. It would also good if anyone could tell me how to turn message validation on.
Regards,
Leo

Hi Nico,
In multithreading, all the threads are independent. Here the threads miao and bau are independent.
There is no guarantee which thread executes first. In your program for miao you explisitly called sleep and hence bau thread executed.
Explanation:
========
When you start both the threads miao and bau both are in runnable start. Only one thread can go to running. Lets consider miao goes to running state. Because you called sleep miao goes to sleeping and bau goes to running state and once the sleep completed for miao it goes to runnable state and as bau is in running and once bau completes miao again goes to running state and then it also completes.
Thanks & Regards,
Murali.

Every sync gets "You are about to synchronize your calendar for the first time" - Help !!!

I am on a MBP with the Tour and was able to successfully sync iCal and Address Book with BB. But everytime I try to sync, I get the " You are about to synchronize our Calendar data for the first time." with the options to "Replace Device Data", "Merge Data" or Cancel. Has anyone seen this and know how to fix? Replacing data makes it impossible to update Mac with changes on BB.
Please help!

Create a backup of your iCal and your BlackBerry.
Then create a test Calendar event on the BlackBerry, in iCal then test another synchronization once again.
The first time sync prompt usually occurs when it does not detect entries in either the BlackBerry or iCal Calendar.

Jagged Fonts - My First Logo -Help Plz

I've gotten my first freelance job, and I'm designing the logo.
It came out great, but I just noticed today that when I save it as an eps or a pdf, the fonts are extremely jagged.
I'm worried my client will be unable to successfully take this file to a printer.
I am using Illustrator CS2, and using fonts Impact and Times New Roman.
What could be causing this? I am getting flagged for "Only fonts with appropriate permission bits will be enabled." and "This document contains artwork that requires flattening."
Any help is appreciated.

I think there are settings when you go to print as a pdf where you can make it print in high resolution. I had a publication I did once and the initial pdf's were not clear for printing. NOTE - I did the publication in InDesign, NOT PhotoShop. In speaking with the printer he walked me through a way that made it come out crystal clear. Of course the file was huge (250 Megs) but not a problem because I ftp'd it up.
In InDesign I EXPORTED the pdf, but I don't see that feature in PhotoShop. However, there is a Export Paths to Illustrator. I have not done this but you might play with it. I usually create vector logos then export to a bitmap format and get better results...not that I'm a pro like so many others on these forums, but it works for me.
In the meantime you might want to contact a local commercial printer in your area and ask if they can help direct you. Some work with you and others shun you.
Best of luck.

Hi,
I think Bill has given the unambiguous solution.
In all my years as an administrator of an internet data center, networking Architecture is flexible. Network schema is always changed for meeting a variety of needs. There isn’t an only standard for it.
In your case, the solution which is given by Bill works best for you.
In addition, if there is any misunderstanding, please let us know what you would like to achieve.

Depth First Search help

I have an assignment to do on a graph and have to apply depth first search so it ouputs the vertices in a order. I understand the algorithm and can do it on paper but i cannot do it in code so if anyone can help me on this. Here are the classes i am working with
public class MatrixGraph extends AbstractGraph {
    private double[][] matrix;
    public MatrixGraph(int nV, boolean direct, boolean weight ){
        super(nV, direct, weight);
        matrix = new double[nV][nV];
        // if a weighted graph set all values to Double.POSITIVE_INFINITY
        // otherwise set all values to 0
        //complete this code
    public boolean isEdge(int source, int dest) {
        throw new UnsupportedOperationException("Not supported yet.");
    public void insert(Edge edge) {
        throw new UnsupportedOperationException("Not supported yet.");
    public void remove(Edge edge) {
        throw new UnsupportedOperationException("Not supported yet.");
    public void depthFirstTraversal(int start){
        //Output the vertices in depth first order
public abstract class AbstractGraph implements Graph {
    private int numV;
    private boolean directed;
    private boolean weighted;
    public AbstractGraph(int nV, boolean direct, boolean weight){
        numV = nV;
        directed = direct;
        weighted = weight;
    public int getNumV() {
        return numV;
    public boolean isDirected() {
        return directed;
    public boolean isWeighted() {
        return weighted;
public interface Graph {
    //returns the number of vertices
    int getNumV();
    // determine if this is a directed graph
    boolean isDirected();
    // determine if this is a weighted graph
    boolean isWeighted();
    // determine if an edge exists between source and destination
    boolean isEdge(int source, int dest);
    void insert(Edge edge);
    void remove(Edge edge);
}

}I need help on this part i don't know how to write it.You mentioned you understand the algorithm and can do it on paper so what have you tried so far?
If you are completely stuck on implementing the traversal in Java, provide pseudo code.

Noobs first forum help request.

Hi.
I'm a Brit living in Korea and after 7 years of cell phone **** (having a phone that has only partial and badly written English menu)I finally got an iphone.
The manual is in korean and although i've changed all the language settings to English I have to admit that i dont know how to use some features.
Here are a few initial questions. I hope someone can help.
1. Is there any way to see a menu of 'all' the free apps in intunes and not just the top 100?
2. When I make vidios they play well on the iphone but are very stuttery on my pc. Is there a reason for this.
3. I have no idea how to transfer my mp3 collection onto my iphone. I plugged it in and on my computer it just shows up as a camera. When i look into it i can only see photos and videos. When i dragged and dropped a folder into itunes it just dropped the contents and they get mixed up with all the other song on it. After syncing though, when select 'ipod' it says no content? Im confused.
The tutorial videos on itunes seem more like marketing videos than actual in depth help vids. Is there any link where i can find specific vids to hep me. I used monkeysee.com but they were all from version 2.
4. It's a pain when i watn to organize the apps and their positions. Even when i do it with itunes. When i move one app say to the first screen it messes up the position of all the other apps. Is there anyone to lock an app so it stays exactl where i put it even if i move other apps onto or around that screen?
5. Why can't i get rid of the apps that i will 'never' use such as stocks?
6. Is there a manual i can download that shows me all the basics of how to use my iphone?
That's all for now.
Thank's.

Hi, unfortunately there is no way to remove the apps that come pre-installed (from Apple) off of the iPhone. This is just the way they made it. As far as the music goes, when ever you drag a folder or import a CD the contents within that item will add into iTunes and not the folder itself or CD. If you want certain content in a certain place you can create playlists by going to File>New Playlist in iTunes on your computer. As far as "locking" apps goes you just have to keep them where you want them. If you put the app you want on a certain home screen between 2 other apps its going to put the one you want in the middle and vice versa.
As far as free apps in itunes you can try searching "free apps" and see what results come back. Not sure if this will show all or some but may help.
Here is the link for the iPhone manuals.
Hope this Helps!!

Need Mac to automatically boot as first partition (HELP)

hi guys, i have windows and mac on a different partition and i use Alt button to select,
How do i automatically make MAC my first partition to boot
any advice would be great!!
I should probs state that i am running on a Imac27" running on the I3 processor and have the latest MAC OS 10.6 or something like that (bought this mac about christmas so not too old!)
jon

Hi,
boot your Mac into OSX.
In OSX go to System Preferences then Startup Volume and set your OSX volume to be the default.
On the next reboot your Mac should automatically boot into OSX.
To get to Windows again you would have to use the Alt/Option-key at startup.

Apple TV Photo stream shows photos OLDEST FIRST.. help!

I love the apple tv, but the photostream is driving me nuts. It's pretty useless. I select photostream (now icloud in the latest update) and my photo stream appears with the oldest photos first! I want to see my newest photos, not scroll through hundreds of photos to find the newest additions. How do I fix this?
I have the 3rd generation apple TV with the latest update.
thanks.

The subject refers to photo stream, but your post is dealing with home sharing.
If it is home sharing, as your post indicates, then both need to be on the same network (same location) as well as have the same ID

Running Windows 7 on Dell laptop, Yahoo is set as homepage, but Firefox start page always appears first. Help!

Recently, I downloaded the latest Adobe Reader update. I am not sure if it is related to the problem. For years, I've run Mozilla Firefox and I prefer it to IE. Suddenly, I find that after booting-up, my homepage has been "hijacked" to show the Mosilla Firefox start page, even though my control panel shows my homepage to be yahoo. ( I DID select Yahoo.) How can I get rid of Mozilla Firefox wanting to show itself FIRST? This always happens, starting just in the past two days or so. It's as if Mozilla Firefox has decided: "Yes, you chose Yahoo for your homepage, but I don't care. I want you to be shown OUR page before anything else." It defeats the purpose of selecting a homepage. I'd welcome a solution to this problem!

Just to be sure: In the preferences you do have ''"Show my homepage" ''enabled parallel to the yahoo URL visible in the box?
