No, that is not necessary. Only if you are not satisfied with the
standard connection that you get with the Simple Bootstrap process or if
you want to connect to an OOo instance that is not running on the same
machine as your application.

If *your* program wants to use a specific communication channel then of
course you will need to know which one you want to use. But OOo does not
enforce that. If you are fine with whatever connection OOo uses, you can
ignore which it is exactly.

It not only starts OOo, it already connects to it and gives you an
object that can be used to create and access others. See the attached
source code that loads a document via UNO (I tried to link to the source
code on api.openoffice.org but for whatever reasons it's not there).

I don't understand why you want to know that. The Component Context you
have bootstrapped is your entry to the UNO world and gives you
everything you need. What else do you want to achieve by establishing
another connection?
I don't know what answers you will get here - in case they don't satisfy
you you could perhaps try to get more information on [EMAIL PROTECTED]

I use it for the OOo lists and only rarely read other mails sent to it.
