Embed Adobe Reader with OLE into Java client

Hi all,

I am trying to integrate Adobe  Reader 9.3 using OLE into an Eclipse base Java client using SWT.

However  the basic initialization of the OLE Control fails with this error:

Unable to open type library  for AcroPDF.PDF.1
org.eclipse.swt.SWTException: Failed to create Ole  Client. result = -2147221164
    at  org.eclipse.swt.ole.win32.OLE.error(OLE.java:302)
    at  org.eclipse.swt.ole.win32.OleControlSite.<init>(OleControlSite.java:142)

        ...

Here  is the code I used:

String  progID = "AcroPDF.PDF.1";

Shell shell = new Shell();

OleFrame frame = new  OleFrame(shell, SWT.NONE);
OleControlSite site = null;
OleAutomation  auto = null;

try {
     site = new OleControlSite(frame, SWT.NONE, progID);
    auto = new  OleAutomation(site);
} catch (SWTException e) {

         System.err.println("Unable  to open type library for " + progID);
    e.printStackTrace();
    return;
}

I can see  the key "AcroPDF.PDF.1" in my registry...

Does anybody know what I am missing  here?

Thanks!

Paul
