Bizzare resource loading problem

Question

I'm working with an API that utilizes a Java to COM bridge. During the execution of the API methods a Windows DLL is loaded and used. I have written a test program that calls one of the APIs methods without an exception.
So what does this have to do with Swing? Everything works fine until I port my code into a Swing application. Then after the UIManager.setLookAndFeel() call when I call my API method again I get an exception from the COM object that a necessary DLL cannot be found. I have a suspicion that this has something to do with the class loader. Any ideas would be appreciated. Here's a code snippit to help you understand the order of things:
    QBXMLTest qbtest = new QBXMLTest();
    System.out.println(qbtest.getClass().getClassLoader());
    qbtest.go();
    try {
      UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
    catch(Exception e) {
      e.printStackTrace();
    QBXMLTest qbtest2 = new QBXMLTest();
    System.out.println(qbtest2.getClass().getClassLoader());
    qbtest2.go();Thanks,
Jack

Hi,
do the following
InputStream in = Mainclass.class.getResourceAsStream("filename");
DataInputStream din = new DataInputStream(in);
int i = -1;
ByteArrayOutputStream bos = new ByteArrayOutputStream();
byte data[] = new byte[1024];
while((i = din.read(data)) != -1)
   bos.write(data, 0, i);
bos.flush();
din.close();
data = bos.toByteArray();
