Sony Ericsson SDK for the Java ME platform 2.5.0.3
Downloaded Sony Ericsson's latest SDK (111 MB). About twice
the size of Nokia SDK.
During installation in Vista I get error message:
"WTK2 emulator needs VoiceAge.DLL in order to work"
To solve this, open the cmd shell as Adminstrator (Right click
on the cmd icon from Start menu and Run as Adminstrator).
Then execute this command whilst in the default system32
directory:
Later after trying again to install, another message came up:
"Need to close this program before continuing: jsl.exe"
Just click next, the installer will kill the process and continue.
After installation, the process to link the SDK to Netbeans 6.5 is
the same as for the Nokia SDK.
However, you will note that there are two platforms added.
The first one is as shown below, Debug On-Device SDK.
The second one is the Emulator. See below:
When running tests, you should use the Emulator. There are many
Sony Ericsson mobile phone models. For example, K510:
The above K510 emulator is running the World Clock Program

Netbeans 6.5 installation
At time of writing, Netbeans 6.5 is the latest edition.
After downloading from netbeans.org, the barebones
edition i.e. the Netbeans 6.5 SE, it does not come with
JWTK 2.5.2. You will need to add it as a Platform
by clicking on the Tools menu, then Java Platform,
then add Java Platform.
But before you can do that, you will need to install
a plugin first. Goto Tools, then Plugins, then add the
mobility plugin. It's around 9 MB to download.
After intsalling that, then only add the JWTK Platform.
Two other optional plugins are the mobility vmd and
mobility end-to-end.
moility vmd enables you to design the midlet's
GUI visually and also has flow layout view.

Workaround to List Bug in Nokia SDK 6th Edition
Running the application compiled under SDK 5th edition
on the SDK 6th edition's emulator:
A temporary work-around to the List Bug:
In Netbeans 6.5, compile the application using SDK 5.
Then fire up your SDK 6 emulator (outside of Netbeans 6.5).
Use the File menu, navigate to the dist folder of the Netbeans
project. You will find a .jad and a .jar file there.
Open the .jad file (emulator will then execute the .jar).
The above image is the result. Works like
a charm! This temporary workaround will do for now,
while waiting for Nokia to fix the bug.

List Bug in Nokia Series 40 SDK 6th edition
Using Nokia Series 40 Emulator Edition 5:
TheList Bug:
I found a new bug in Nokia Series 40 SDK Edition 6
(which was released last month: Nov, 2008), which I
now call the 'List' Bug.
I tried to compile the following code:
private String sCities[]={"KL","PG"};
private int hr, min;
public WorldClock() throws IOException {
citylist=new List("World Clock 0.0.22",List.IMPLICIT,sCities,null);
cmExit = new Command("Exit", Command.ITEM, 2);
citylist.addCommand(cmExit);
citylist.setCommandListener(this);
}
And it raised this compiler error:
class file for javax.microedition.lcdui.ChoiceVector not found
citylist=new List("World Clock 0.0.22",List.IMPLICIT,sCities,null);
I then downloaded the earlier Edition 5 (2007) and it compiled fine.
It appears that Edition 6 SDK wrongly called the non-existent
ChoiceVector to create the List.
Status of World Clock Project:
As can be seen in image above, I am now able to simulate
an analog clock in real-time.

World Clock Project using Nokia Series 40 Emulator Edition 6
This is what it looks like using the Nokia Series 40 Emulator Edition 6:
You need to integrate the Nokia SDK to Netbeans 6.5 first.
From Tools Menu select Java Platforms then select
C:\Nokia\Devices\S40_6th_Edition_SDK
The project is not finished yet. The above is just a testrun
on the initial clockface design.
