I cannot set Factory on ConnectionCreationTool, my version of GEF is 1.0,
have you added it in GEF 2.0?
If you set the Factory on the ConnectionCreationTool, it should provide the
new Type and instance information to the request.
Someone at IBM requested this about 6 months ago so I believe it should
work.

I mean GEF 1.0 which is embeded in the WSAD 4.11 IE version.
And I get the documents of GEF 1.0 from an internal site of IBM.

Ok. this didn't work in 1.0. No one was trying to do this, or if they did,
they were subclassing our tool instead of reporting the bug.
You can probably workaround this in 1.0. You might have to override the
conneciton tool's createRequest method, and set the factory on the request.
Sorry, I don't have 1.0 code installed right now.
