I need help in coding. I have setup up UIQ3.1 in my PC, and tried to make the emulator to work with my network. I've tried so many times but I just can't get the emulator to work with XP's network. The document of UIQ3.1 seems not quite clear how to setup the networking. Can somebody guide me the detail of setting up the network? What I'm trying to do is to write a java program which can retrieve database or a CSV file from a server and get some text stream back on the screen. If it is not possible to setup a network through the emulator. Can somebody show me an example code for reading a 54MB sized CSV database file, and input a string of text or numbers, than retrieve a part of that CSV content to the screen. At the mean time, store the input stream with a small database locally. The other function is to retrieve the stored database with an add and extract function to the database? I would like to see the code and I will...

I have read all the relevant JavaME documentation but I am lost when it comes to the UIQ 3 specialities. My code looks a bit like: javax.microedition.io.file.FileConnection connection = and #40;javax.microedition.io.file.FileConnection and #41; javax.microedition.io.Connector .open and #40;filename and #41;; java.io.DataInputStream out = connection.openDataOutputStream and #40; and #41;; out.write and #40;0x00 and #41;; out.close and #40; and #41;; connection.close and #40; and #41;; For a filename I tried file:///fx-602p.df, file:///C:/other/fx-602p.df, file:///D:/other/fx-602p.df. But all my code currently does is to produce an all sorts of security warnings but no file appeared anywhere. Now I have few questions: 1. Is general direction right? 2. What should the filename correctly look like on UIQ 3 devices? 3. What can I do to min...

For those of you who don't know this, it's a j2me application that let's you control a desktop computer through a mobile phone. It's open source and under GPL license. I made a few changes all around the application and I also included some new funcionalities. This version comes with a VNC server which I also made changes too, allowing you to transfer sound, set user profiles, use server side scaling... I would appreciate your feedback, comments, ideas and so one, so I could try to improve this. I only tested this in a few nokia mobile phones so I don't know how it will work (or not) in other platforms...feedback on this would also be great :) You can check the project at: http://web.ist.utl.pt/nfcf/ The original project can be found here: http://j2mevnc.sourceforge.net/ You should read the user guide I made to understand how to work with the ...

Basically, the application should repeat whatever the mobile user says (audio feedback), according to a specific delay value (i.e., repeat what has been said after 1.2 seconds, or after 300 milliseconds). I started with the following code but i am stuck: Player player = Manager.createPlayer(capture://audio); player.realize(); player.start(); I don't think I will need the RecordControl since I do not want to record the audio on a file or in-memory, I just want to relay it back. Or shall I record it in-memory using an OutPutStream and initialize a new player with an InputStream that is connected to the OutputStream? I would really appreciate your help.

I put them for sale on handango and there is absolutely no activity (unlike when I put the same apps for sale on Blackberry). So, I found out from the handango people the following: "Handango does not distribute any content labeled as 'Java' on Handango-branded channels and we have not since over a year ago. If your application is truly meant for Symbian UIQ devices, then you will need to enter your Handango account and create a new product labeled as Symbian rather than Java. Afterwards, the application should be listed on Handango.com." So, I went to release the product as a Symbian OS product. However, I come to find out that for uploading the OTA version, they need SIS files. Here is what it says: (OTA Installation files should be CAB files for PocketPC (or EXE only if the file is compiled with Spb AirSetup), PRC files for Palm OS, and S...
