Problem with my new project [message #696196]

Ok, I'm hoping this is the right subforum for this topic, if not: let me know and I'll change it.

So what I want to do is use the Wiimote for tracking purposes. I found a very nice library called WiiGee, which has some jars for download. I downloaded the jars and included them in my project as internal jars. Basically drag-and-drop into Eclipse and "add jar" via project properties

It didn't work, I got the following error:

Exception in thread "main" java.lang.NoClassDefFoundError: javax/microedition/io/Connector
	at org.wiigee.device.Wiimote.connect(Wiimote.java:133)
	at org.wiigee.device.Wiimote.<init>(Wiimote.java:119)
	at org.WiiGeeTest.controller.WiimoteController.<init>(WiimoteController.java:20)
	at org.WiiGeeTest.controller.WiimoteController.main(WiimoteController.java:43)
Caused by: java.lang.ClassNotFoundException: javax.microedition.io.Connector
	at java.net.URLClassLoader$1.run(Unknown Source)
	at java.security.AccessController.doPrivileged(Native Method)
	at java.net.URLClassLoader.findClass(Unknown Source)
	at java.lang.ClassLoader.loadClass(Unknown Source)
	at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
	at java.lang.ClassLoader.loadClass(Unknown Source)

A friend then told me I needed to download the Java ME SDK. So I downloaded Java SE and got the ME SDK from the Oracle.com-website and installed both setups.

This doesn't do very much, as I'm sure I need to change some settings in Eclipse to make sure it knows about the recently installed SDK. Unfortunately, I have absolutely no idea how to do this. I've been looking at the settings for 2 days now, and still nothing. This project is my master thesis, so I need to get this to work ASAP!!

Any help is appreciated...

Thx

This is the right forum...

Directing Eclipse to use J2ME JAR(s) involves right-clicking on the
project, choosing Build Path, then Configure Build Path and finally the
Libraries tab.

Come back with more pointed questions as they arise. We're glad to help.
