Hi there - VB.Net / C# coder with a sense of adventure here...
I've read a few books on Java, and decided to give it a whirl - having used
Eclipse 3.3 to knock together a quick "Hello World" app with Swing, I've
decided to try and create a small application for mobile phones. EclipseME
looks like just the sort of think I'm after then, no?
So, I've got Eclipse Version: 3.3.1.1 Build id: M20071023-1652 installed to
d:\eclipse\eclipse.
I've got the Sun jre1.6.0_03, hidden away in c:\program files...
I've got the Sun Wireless Toolkit 2.5.2 installed at c:\WTK2.5.2.
EclipseME 1.7.7 running as a plugin on Eclipse...
I've "written" the following as a first midlet...
import javax.microedition.midlet.MIDlet;
import javax.microedition.midlet.MIDletStateChangeException;
public class CMainForm extends MIDlet {
protected void destroyApp(boolean arg0) throws
MIDletStateChangeException {
}
protected void pauseApp() {
// TODO Auto-generated method stub
}
protected void startApp() throws MIDletStateChangeException {
// TODO Auto-generated method stub
}
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
}
}
In other words - just the stubs... When I try and debug this in eclipse, I'm
getting a UnsatisfiedLinkError. Here's the stack trace:
Exception in thread "main" java.lang.UnsatisfiedLinkError:
com.sun.midp.main.Configuration.getProperty0

-2
JDWP exit error AGENT_ERROR_NO_JNI_ENV(183):
[../../../src/share/back/util.c:820]
I've tried looking on Google, and it seems this is a common problem, and one
that ought to be obvious for people who know what they are doing with
Eclipse. Any cnance of a hint for us beginners?
Cheers,
Martin
