[news.eclipse.tools] Using CLSIDFromProgID method

[tmcguire@xxxxxxxxxxxx (Thomas McGuire)]

Hello,
    I'm a developer in a pure-java application that supports COM for
certain operations.
    I need to get the classID from a progID on win32 platforms and I
discovered the method CLSIDFromProgID in the class
org.eclipse.swt.internal.ole.win32.COM

    I recognize that the package is internal, but assuming (for now) that
I'll always run on win32, can someone tell me how to use this function? 
No matter what I pass in, I get an undecipherable result integer, and the
arguments don't appear to be changed (I'm assuming the GUID is an in,out).
     Thanks for any help anyone can provide.
