Unknown ALERT while loading class

Question

When I try to load a class in the kvm I get the following error:
"ALERT: Cannot create class in system package"
I've done a Google search, and a search on this site, with no luck. Am I the first person to get this error?
I have a few ideas about what might be causing it. If anyone could confirm or deny them, I'd appreciate it:
#1. This is prime culprit-> Dynamic class loading via Class.forName. Does the stripped down JVM support all the functionality I need for this?
#2. Am I not specifying the classpath correctly? I tried adding J2ME's src directory and J2SE's rt.jar to the classpath to no avail.
#3. Did I preverify incorrectly? I didn't get any errors, but without verbose output, I can't be sure exactly what happened anyway.
Any help would be greatly appreciated.

Answer 1

Let me explain the situation in more detail
I have a MIDlet class, that is in my own package JMarket:
package JMarket;
import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;
public void startApp() {
mm = new Form("Welcome to JVS!");
//make connection to Bluetooth Server
connect = new JvsConnect(); if I uncomment this line error message disappears
Let me now show you my JvsConnect class:
package JMarket;
import javax.bluetooth.*;
import javax.microedition.io.*;
import com.rococosoft.impronto.configuration.*;
import com.rococosoft.impronto.util.*;
public class JvsConnect {
These two lines cause the problem.When I uncomment them error is gone
private static LocalDevice device = null;
private final static UUID uuid = new UUID(0x7C3434CC);
public JvsConnect() {
System.out.println("Starting Bluetooth Connection...");
In my project properties(in JBuilder), as required library I have Impronto's APIs (without them I cannot say " import com.rococosoft.impronto.util.*; " - which is needed for bluetooth connection "LocalDevice" and others..)
So as you can see when I only uncomment two lines from JvsConnect class error message is gone and MIDlet can do everything ok....Otherwise it always says ALERT: Cannot create class in system package
What is wrong???
