如何在java eclipse插件中使用自定义OLE dll？(How to use a custom OLE dll in a java eclipse plugin?)

 我想在我的Eclipse RCP插件中使用带有控件的自定义OLE dll。 
 
 dll在我的工作目录中，但如果我尝试使用它，我会得到一个SWTException： 
 
 我使用这个代码： 
 
Display display = Display.getCurrent();
Shell shell = new Shell(display);
OleFrame frame = new OleFrame(shell, SWT.NONE);
OleClientSite site = new OleClientSite(frame, SWT.NONE, "MyCustomDll.TestControl");
OleAutomation test = new OleAutomation(site);
shell.open();
 
 并得到这个例外： 
 
org.eclipse.swt.SWTException: Class ID not found in registry
  at org.eclipse.swt.ole.win32.OLE.error(OLE.java:317)
  at org.eclipse.swt.ole.win32.OLE.error(OLE.java:283)
  at org.eclipse.swt.ole.win32.OleClientSite.<init>(OleClientSite.java:226)
  ...
 
 我怎么能告诉我的插件在哪里寻找类ID？ 必须有一些我缺少的基本点，但我没有找到任何关于使用自定义OLE dll的信息。 

I'm trying to use a custom OLE dll with a control in my Eclipse RCP Plugin.
 
The dll is in my working directory, but if I try to use it I get a SWTException:
 
I use this code:
 
Display display = Display.getCurrent();
Shell shell = new Shell(display);
OleFrame frame = new OleFrame(shell, SWT.NONE);
OleClientSite site = new OleClientSite(frame, SWT.NONE, "MyCustomDll.TestControl");
OleAutomation test = new OleAutomation(site);
shell.open();
 
And get this Exception:
 
org.eclipse.swt.SWTException: Class ID not found in registry
  at org.eclipse.swt.ole.win32.OLE.error(OLE.java:317)
  at org.eclipse.swt.ole.win32.OLE.error(OLE.java:283)
  at org.eclipse.swt.ole.win32.OleClientSite.<init>(OleClientSite.java:226)
  ...
 
How can I tell my plugin where to look for the Class ID? There must be some basic point I'm missing but I didn't find anything about using custom OLE dlls.
