Hi there,
while poking around a little bit I was wondering, how one could get at
the "Type[...]" information via Java that the Java proxy object reveals,
if asking it to render to a string.
E.g. in the following (interactive) session Java is used as the bridge
for the scripting language ooRexx; first a Desktop service object is
created and assigned to a variable "a", then its
"com.sun.star.frame.XDesktop" interface is assigned to variabel "b" and
from it the "com.sun.star.beans.XPropertySet" interface is assigned to
variable "c". Sending the "toString" message to all three proxy objects
displays them allowing to distinguish which interface type they represent.
In the example session below (please watch out for line-wraps) that
interface type is the last comma separated token in the form of
"Type[...interface_name...]".
Now the question: how can one get at exactly that piece of information
via Java at runtime?

REXX-ooRexx_3.2.0(MT) 6.02 16 Jun 2008
rexxtry.rex lets you interactively try REXX statements.
Each string is executed when you hit Enter.
Enter 'call tell' for a description of the features.
Go on - try a few... Enter 'exit' to end.
call uno.cls
