Error calling JNI method

Question

Hello Everyone,
I´m trying to call a method wich is inside a DDL by JNI. This works fine in a Java console application. However, this call doesn´t work when i put this operation in a web apllication and deploy in a weblogic server. I´ve already put the dll path in the PATH variable but it didn´t work. When I debug the application, the DLL can be loaded but i call the native method a error happens and a get the following message:
java.lang.UnsatisfiedLinkError: criptografa
     at com.tim.util.cripto.ACC_Cripto.criptografa(Native Method)
Why does it work when I use a java console application ?
Thanks for help

I see yere points but what I see on linux is it makes it to the constructor of the Java object and somewhere afterwards it bails out, the Java app does work alone. It appears to have problems initializing the JFrame, could there be a problem with the Java inheritance when a JVM is invoked throurgh native invocation??
Here's some of the Java stuff
public class Framework extends WindowAdapter {
    public int numWindows = 0;
    private Point lastLocation = null;
    private int maxX = 500;
    private int maxY = 500;
    public Framework() {
        System.out.println("JAVA Framework cnst");//GETTING HERE
        makeNewWindow();
    public void makeNewWindow() {
        System.out.println("JAVA makeWindow"); //GETTING HERE
        JFrame frame = new MyFrame(this); //NOT GETTING HERE!!!!!!!!!
        numWindows++;
        System.out.println("Number of windows: " + numWindows);
        System.out.println("Frame location: " + lastLocation);
        frame.setVisible(true);
        System.out.println("Post Java set frame visible");
    public static void main(String[] args) {
    System.out.println("Main method in Framework");
        Framework framework = new Framework();//GETTING HERE
class MyFrame extends JFrame {
    protected Dimension defaultSize = new Dimension(200, 200);
    protected Framework framework = null;
    public MyFrame(Framework controller) {
        super("New Frame");
        System.out.println("MyFrame cnst ");//NOT GETTING HERE!!!!!!
        framework = controller;
        setDefaultCloseOperation(DISPOSE_ON_CLOSE);
        addWindowListener(framework);
        JMenu menu = new JMenu("Window");
        menu.setMnemonic(KeyEvent.VK_W);
       setSize(defaultSize);
}
