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
